Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The page information updating method provided by the application can be applied to an application environment as shown in fig. 1, wherein a client communicates with a server through a network, the client acquires a current js script from the server, sends a standard version information inquiry request to the server according to a basic script identifier in the current js script, returns standard version information, carries out consistency check on the standard version identifier and the basic version identifier to obtain a first check result, acquires an latest js script corresponding to the basic script identifier from the server if the first check result is inconsistent in version, replaces the current js script with the latest js script to obtain an updated current js script, and finally loads the updated current js script so that page information corresponding to the updated current js script is displayed on an interface. The clients may be, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server may be implemented by a stand-alone server or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, the method is applied to the server in fig. 1, and the method includes the following steps:
s10: if the page loading request is detected, acquiring a current js script contained in the page loading request, wherein the current js script comprises a basic script identifier and a basic version identifier.
The JavaScript is an transliteration script language, and is a dynamic type, a weak type and a language based on a prototype, and a built-in support type is adopted. A file written in JavaScript is called JavaScript script (js script for short). The js script can be embedded in the current HTML page to add various dynamic functions to the webpage, and can be written as a single js script to separate the structure and the behavior of the webpage. The current js script in the embodiment refers to a JavaScript script in the current access webpage, so that the page structure information and the behavior are separated through the current js script, and the information rapid updating process of the current access webpage is realized.
Wherein the base script identification is used to uniquely identify the current js script. The base script identification may be, but is not limited to: the script name, the current page Identifier (ID), the update time, etc., for example, a basic script identifier is denoted as "2018-09-19" by the update time, and may be set according to actual needs, which is not particularly limited herein.
Wherein the base version identification is used to uniquely identify the version number of the current js script. The base version identification may be, but is not limited to: the version number, update time, or other symbols for distinguishing different version numbers, such as a random number and a combination of the version number and the timestamp, may also be set according to actual needs, and is not particularly limited herein.
Specifically, when the client detects a page loading request for a page, the client obtains a current js script contained in the page loading request, and the page loading request can be automatically triggered by the client or can be passively triggered when the client is detected to operate by a user, and the setting can be specifically performed according to actual needs, so that the method is not limited.
For example, in a specific embodiment, when a certain operation of the client by the user is detected, a loading request of the client for the page, namely, the home page of "happy and safe", is passively triggered, so that a current js script contained in the page loading request is obtained, where the current js script includes a base script identifier "happypa 1.0.0" and a base version identifier "version1.0".
S20: and sending a standard version information query request to the server according to the basic script identification.
The standard version information refers to the suffix content of the js script file of the server corresponding to the basic script identifier, and is used as a basis for judging whether the js script of the server is consistent with the current js script. The current js script includes a base script identifier, and accordingly, a base script identifier corresponds to a standard version information. For example, a server js script corresponding to the basic script identifier is "< link rel=" stylesheet "href="/css/index. Cssver=10 "/>, and it is understood that the suffix content of the server js script is" ver=10 ", that is, the standard version information is" ver=10 ".
The standard version information query request is a query request for acquiring standard version information of the js script of the server side, so that whether the current js script corresponding to the basic script identifier is consistent with the js script of the server side or not can be judged later, and the condition that after the js script of the server side is updated, the client side still loads the js script (cache page) which is not updated is prevented, so that abnormality occurs.
Specifically, the client sends a standard version information query request to the server, the query request comprises a basic script identifier, and the browser is prevented from caching the current js script by sending the standard version information query request to the server according to the basic script identifier, so that cache information is directly loaded, an updated page is not loaded, and abnormality occurs.
S30: and receiving standard version information returned by the server, wherein the standard version information comprises a standard version identifier.
The standard version identification is used for uniquely identifying the version number of the js script at the server. Continuing with the standard version information "ver=10" in step S20 as an example, the standard version is identified as "10". The standard version identification may be, but is not limited to: the version number, update time, or other symbols for distinguishing different versions, such as a combination of a random number and a version number and a time stamp, may also be set according to actual needs, and is not particularly limited herein.
Specifically, standard version information returned by the server is received, wherein the standard version information comprises a standard version identifier.
S40: and carrying out consistency check on the standard version identifier and the basic version identifier to obtain a first check result.
The consistency check is a check for judging whether the standard version identifier is consistent with the basic version identifier, so as to judge whether the server js script is updated or not. For subsequent further processing of the page load based on the consistency or non-consistency of the information. The consistency verification method can be a verification algorithm based on the editing distance, a verification algorithm based on similarity, or a verification algorithm based on approximate search.
The first verification result is obtained by comparing the consistency of the standard version identifier and the basic version identifier, and comprises inconsistent versions and consistent versions.
It can be appreciated that if the first verification result is that the versions are consistent, the standard version identification is unchanged, and the current js script is unchanged. Because the request is still the original address, the current js script is read from the local browser cache without increasing the burden on the server. If the js script at the server side changes, the browser caches the current js script, and the basic version identifier corresponding to the current js script is unchanged, namely, the standard version identifier and the first verification result of the basic version identifier are inconsistent in version, at the moment, the page information obtained by page loading is abnormal, so that consistency verification is carried out on the standard version identifier and the basic version identifier, the page corresponding to the standard version identifier is prevented from being loaded, and the accuracy of page information loading is ensured.
S50: and if the first verification result is that the versions are inconsistent, acquiring the latest js script corresponding to the basic script identifier from the server.
The latest js script refers to the js script updated by the server page last time. After the script is reloaded, the loading of the cache page is avoided, the loading to the latest js script is ensured, the latest js script is processed later, and the page loading accuracy is improved. The basic script identification has a corresponding relation with the latest js script, namely, the corresponding latest js script can be obtained through the basic script identification
Specifically, when the server js script is updated, the first verification result is that the versions are inconsistent, and at the moment, the server acquires the latest js script corresponding to the basic script identifier, so that a cache page corresponding to the current js script is prevented from being loaded, the latest js script is ensured to be loaded, the latest js script is processed later, and the page loading accuracy is improved.
S60: and replacing the current js script with the latest js script to obtain an updated current js script.
Specifically, after the latest js script corresponding to the basic version identifier is obtained from the server, the latest js script is used for replacing the current js script, namely the latest js script is used as the updated current js script, so that the current js script is updated, and the phenomenon that page information is abnormal due to the fact that the browser accesses a cache page due to reloading of the current js script is avoided.
S70: and loading the updated current js script, so that page information corresponding to the updated current js script is displayed on the interface.
Specifically, after reloading the updated current js script, the cache page corresponding to the current js script is prevented from being loaded, and the page corresponding to the latest js script is ensured to be loaded, so that the latest page content is acquired and displayed on the interface. The page updating efficiency is improved.
In this embodiment, if a page loading request is detected, a current js script included in the page loading request is obtained, so that the page structure information and the behavior are separated through the current js script, thereby implementing the rapid update processing of the information of the current access page. And sending a standard version information inquiry request to the server according to the basic script identification, so as to prevent the browser from caching the current js script and loading the cache information. And receiving standard version information returned by the server. And then, carrying out consistency check on the standard version identifier and the basic version identifier to obtain a first check result, preventing the page corresponding to the standard version identifier from being loaded, and ensuring the accuracy of page information. If the first verification result is that the versions are inconsistent, the latest js script corresponding to the basic script identification is obtained from the server, the page corresponding to the current js script is prevented from being loaded, the latest js script is ensured to be loaded, the latest js script is conveniently processed, and the page loading accuracy is improved. And replacing the current js script with the latest js script to obtain an updated current js script. And finally, loading the updated current js script, so that page information corresponding to the updated current js script is displayed on the interface, and the page information updating efficiency is improved.
In one embodiment, as shown in fig. 3, in step S40, consistency verification is performed on a standard version identifier and a basic version identifier to obtain a first verification result, which specifically includes the following steps:
S41: extracting character strings contained in the standard version identification as standard character strings, and extracting character strings contained in the basic version identification as basic character strings.
The standard character strings refer to character strings contained in the standard version identification, namely, character strings with preset number in the standard version identification are extracted. For example, the first 10 character strings of the standard version identification are extracted as standard character strings. The basic character strings refer to character strings contained in the basic version identifier, namely, the character strings with preset quantity in the basic version identifier are extracted. It should be noted that, the extraction rule of the standard character string is consistent with that of the basic character string, so as to ensure that the subsequent comparison is accurately performed.
Preferably, all character strings in the standard version identifier are extracted as standard character strings, and all character strings in the basic version identifier are extracted as basic character strings, so that the accuracy of subsequent calculation is improved.
S42: and calculating the editing distance between the standard character string and the basic character string by using an editing distance algorithm, and taking the editing distance as a target editing distance.
The edit distance (EDIT DISTANCE) is also called as a Levenshtein distance, and refers to the minimum number of editing operations required for converting one character string into another character string between two character strings, and if the distance between the two character strings is larger, the similarity between the two character strings is lower. The editing operation of the license includes replacing one character with another, inserting one character or deleting one character.
The edit distance algorithm is an algorithm for measuring the similarity of two character strings by taking the edit distance as the similarity. For determining whether the two strings are identical. The target edit distance is the distance required to obtain two identical character strings after three operations, i.e., inserting, deleting or replacing one of the two character strings. In this embodiment, the distance required to obtain the character string identical to the standard character string is obtained after three operations of inserting, deleting or replacing the basic character string. In one embodiment, the names of the standard string and the base string are str1 and str2, respectively. The calculation process of the target editing distance comprises the following four steps:
The first step: initializing a matrix d of (n+1) × (m+1), and allowing the values of the first row and column to increase from 0, where n is the length of the standard string str1 and m is the length of the base string str 2.
And a second step of: the standard string str1 and the base string str2 are scanned simultaneously, if str1[ i ] = str2[ j ], the edit distance 0 is recorded by temp, otherwise, the edit distance temp is recorded as 1.
And a third step of: the matrix d [ i, j ] is given the minimum values of d [ i-1, j ] +1, d [ i, j-1] +1, d [ i-1, j-1] +temp.
Fourth step: after scanning, the last value d [ n ] [ m ] of the matrix is returned, namely the target editing distance.
Specifically, an edit distance algorithm is used to calculate the edit distance between the standard character string and the base character string as a target edit distance. It can be appreciated that the calculation process of the edit distance algorithm is simple and convenient, and the calculated target edit distance can accurately measure the consistency degree of the standard version identifier and the basic version identifier, so in the embodiment, the edit distance between the standard character string and the basic character string is calculated by using the edit distance algorithm, and the consistency check of the standard version identifier and the basic version identifier can be accurately and rapidly performed.
S43: comparing the target editing distance with a preset distance threshold, if the target editing distance is smaller than or equal to the preset distance threshold, the first verification result is that the versions are consistent, otherwise, if the target editing distance is larger than the preset distance threshold, the first verification result is that the versions are inconsistent.
The preset threshold distance is a preset critical distance for measuring the consistency degree of two character strings. Specifically, the purpose of calculating the target edit distance in this embodiment is to perform consistency check on the standard version identifier and the base version identifier, that is, determine whether the standard character string and the base character string are identical. And if the target editing distance is smaller than or equal to the preset distance threshold, the first verification result is that the versions are consistent, otherwise, if the target editing distance is larger than the preset distance threshold, the first verification result is that the versions are inconsistent. For example, when the preset threshold distance is 2 and the target editing distance is 1, the first verification result is that the versions are consistent. It will be appreciated that when the standard string and the base string are identical, the target edit distance is zero. And comparing the target editing distance with a preset distance threshold value, thereby improving the accuracy of consistency verification.
Preferably, the preset distance threshold in this embodiment is zero. And if the target editing distance is equal to zero, the first verification result is that the versions are consistent, otherwise, the first verification result is that the versions are inconsistent.
In this embodiment, the character string included in the standard version identifier and the character string included in the base version identifier are extracted first. Then, an edit distance algorithm is used for calculating the edit distance between the standard character string and the basic character string, and the edit distance is used as a target edit distance, so that consistency check can be accurately and rapidly carried out on the standard version identification and the basic version identification. Finally, the accuracy of consistency verification is improved by comparing the target editing distance with a preset distance threshold.
In one embodiment, as shown in fig. 4, in step S40, consistency verification is performed on the standard version identifier and the base version identifier to obtain a first verification result, which specifically includes the following steps:
s41': the standard version identification is converted into a standard feature vector and the base version identification is converted into a base feature vector.
The standard feature vector is a feature vector of the standard version identifier and is used for representing a vector of text information features of the standard version table identifier, and the basic feature vector is a feature vector of the basic version identifier and is used for representing a vector of text information features of the basic version identifier. In particular, the standard version identification may be converted into a standard feature vector and the base version identification into a base feature vector by a hash vectorization tool. The feature vector can characterize text information features of the version identifier by simple data, and the subsequent consistency check process can be simplified by converting the standard version identifier and the basic version identifier into the feature vector.
S42': and calculating cosine similarity of the standard feature vector and the basic feature vector by using a cosine similarity algorithm, and taking the cosine similarity as the target similarity.
The cosine similarity algorithm is an algorithm that takes cosine similarity as a measure of similarity of two feature vectors. In this embodiment, cosine similarity is used to determine whether two character strings are identical. The cosine similarity value is between 0 and 1. The target similarity is a numerical value for measuring the similarity degree of the standard version identifier and the standard version identifier, and the target similarity is equal to 1, so that the standard version identifier is identical to the basic version identifier.
Specifically, a cosine similarity algorithm is used to calculate cosine similarity of the standard feature vector and the basic feature vector, and the cosine similarity is used as the target similarity, so that consistency verification can be accurately and rapidly performed on the standard version identifier and the basic version identifier.
S43': and comparing the target similarity with a preset similarity threshold, wherein if the target similarity is greater than or equal to the preset similarity threshold, the first verification result is that the versions are consistent, otherwise, if the target similarity is less than the preset similarity threshold, the first verification result is that the versions are inconsistent.
The preset similarity threshold is a preset critical similarity for measuring the consistency degree of two character strings.
Specifically, the purpose of calculating the cosine similarity in this embodiment is to perform consistency check on the standard version identifier and the base version identifier, that is, determine whether the standard character string and the base character string are identical. And if the target similarity is greater than or equal to a preset similarity threshold, the first verification result is that the versions are consistent, otherwise, the first verification result is that the versions are inconsistent. For example, when the preset similarity threshold is 0.98 and the target similarity is 0.99, the first verification result is that the versions are consistent. It will be appreciated that when the standard string and the base string are identical, the target similarity is 1. And the accuracy of consistency verification is improved by comparing the target similarity with a preset similarity threshold.
Preferably, the preset similarity threshold in this embodiment is 1. And if the target similarity is smaller than a preset similarity threshold, the first verification result is that the versions are inconsistent.
In this embodiment, the standard version identifier is first converted into the standard feature vector, and the basic version identifier is converted into the basic feature vector, so that the subsequent consistency verification process is simplified. And then, a cosine similarity algorithm is used for calculating cosine similarity of the standard feature vector and the basic feature vector, and the cosine similarity is used as the target similarity, so that consistency verification can be accurately and rapidly carried out on the standard version identifier and the basic version identifier. Finally, the accuracy of consistency verification is improved by comparing the target similarity with a preset similarity threshold.
In one embodiment, the current js script includes a base security code and the standard version information includes a standard security code.
The basic security code is used for preventing the falsification of the basic version identification of the current js script. The standard security code refers to a character string for preventing the standard version identification from being tampered with. Specifically, whether the version identifier of the page to be loaded is updated or not can be judged by inquiring the version information inquiry request sent by the server, and if whether the page to be loaded is updated or not is judged by only the basic version identifier, one disadvantage exists: the hacker can access the page by modifying the standard version identification, and potential safety hazards exist, so that the hacker is prevented from attacking the page to be accessed through the standard safety code and the basic safety code, and the safety of the user for accessing the page is improved.
In this embodiment, as shown in fig. 5, after the step of performing consistency check on the standard version identifier and the base version identifier to obtain the first check result, and before the step of replacing the current js script with the latest js script to obtain the updated current js script, the page information updating method further includes the following steps:
S51: if the first verification result is that the versions are consistent, the standard security code is input into a preset calculation formula, and the target security code is calculated.
The target security code is a security code obtained by calculating a standard security code according to a preset calculation formula, and is used for improving the security of page access.
The preset calculation formula is a formula for transforming the standard security code according to a certain rule in advance. The standard security codes are transformed by adopting a preset calculation formula, so that the subsequent standard security codes are prevented from being cracked, and the risk of page updating is increased.
Specifically, after the step of performing consistency check on the standard version identifier and the basic version identifier to obtain a first check result and before the step of replacing the current js script with the latest js script to obtain an updated current js script, the method further comprises the step of performing security check on the standard security code. When the first verification result is that the versions are consistent, namely the current js script is not updated, the js script of the server is consistent with the current js script, and at the moment, if the standard security code is not verified, a hacker can access the page by modifying the standard version identifier, so that potential safety hazards exist. The standard security code is input into a preset calculation formula, the target security code is calculated, hacking is prevented, and the security of page access is improved.
S52: and carrying out security verification on the target security code and the basic security code to obtain a second verification result, wherein the second verification result comprises inconsistent security codes and consistent security codes.
The security check refers to a check that determines whether the target security code is consistent with the basic security code, so as to determine the accuracy of the target security code and prevent hacking. Whether the target security code is consistent with the basic security code can be realized by adopting a regular expression algorithm or a character string comparison algorithm.
