The following embodiments may be applied to determining an encoding format of a web page, where the encoding format is generally an encoding manner adopted when creating a web page or a website, and in the related art, the setting of the type of the encoding format is relatively fixed, and after determining the encoding format of the web page, according to a user requirement, a position of each target element in the web page in a display screen and a height and a width of the display may be determined.
According to an embodiment of the application, a method for determining a webpage encoding format is provided.
Fig. 1 is a flowchart of a method for determining a web page encoding format according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S101, obtaining a Uniform Resource Locator (URL), wherein a webpage corresponding to the URL is a target webpage.
In the application, the encoding format of the target webpage is judged, the target webpage can be a webpage designated by a user, each target webpage can comprise different file resources, a path pointing to the webpage can be determined as a Uniform Resource Locator (URL), and the URL can be directly linked to the target webpage.
The encoding formats of different target webpages are different, and the encoding format of each target webpage can be determined through the implementation mode in the application.
And S102, determining the coding format of the target webpage according to the URL and the preset field content.
Through the steps, one coding format of the target webpage can be determined, the target webpage can be determined according to the URL, and the coding format of the target webpage can be determined according to the file content in the target webpage and the field content preset in the file. The preset field content may be determined by determining a charset field commonly used for determining a target web page encoding format, for example, an encoding pointed by a URL includes: < meta http-equ ═ content-type, "content ═ text/html: and charset GBK'/>, the encoding format of the target webpage can be determined to be the GBK encoding format according to the content (charset GBK) in the field.
Determining the encoding format of the target webpage according to the URL and the preset field content comprises the following steps: extracting a preset target character string in preset field content; and determining the coding format of the target webpage according to the extracted preset target character string and URL. Wherein the preset target character string may be "charset". The encoding format of the webpage can be extracted through the preset target character string.
The preset target character string in the above embodiment may also be a field written by the user, for example, bm-gbk. The user can determine the field mode capable of judging the coding format according to the self-written code.
And step S103, determining the coding format of the target webpage according to the URL and the character string conversion mode.
In the above embodiment, the character string conversion manner may include multiple manners, and since the web page content corresponding to each URL is different, when determining the encoding format of the target web page, the URL character or the encoded file content of the target web page corresponding to the URL may be converted into a corresponding character string, for example, the encoded file content of the target web page is converted into a binary form.
Optionally, determining the encoding format of the target webpage according to the URL and the character string conversion method includes: converting the target webpage into a page in a character string format; converting the page in the character string format into a byte stream by adopting a first preset encoding format; converting the byte stream into a target character string by adopting a second preset encoding format; and judging the encoding format of the target webpage according to whether the target character string comprises characters of a preset format type.
Optionally, the first preset encoding format may be a GB2312 encoding format, and the GB2312 encoding may be divided into 94 regions, each region has 94 bits, and each region has only one character, so that the region and the bit in which the region and the bit are located may be used to encode the content in the target web page. The page in the character string format can be converted into the byte stream through the first preset encoding format, and the page in the character string format can be converted into the file in the byte stream format through GB2312 encoding under the condition that the character string format is the target webpage content represented by the binary system.
The second predetermined encoding format may be a plurality of encoding formats, such as UTF-8 encoding format. The file of the target web page represented by the byte stream may be converted into a target character string by the second preset encoding format, and a specific character, for example, a chinese character, may be included in the target character string.
In another optional implementation manner, the characters of the preset format type are chinese characters, and the determining the encoding format of the target web page according to whether the characters of the preset format type are included in the target character string includes: if the target character string comprises Chinese characters, determining the encoding format of the target webpage to be UTF-8; and if the target character string does not comprise Chinese characters, determining that the coding format of the target webpage is GBK or GB 2312.
Through the implementation, the encoding format of the target webpage can be determined. The encoding format may be the same as or different from the encoding format determined using the preset field content.
And step S104, judging whether the encoding format of the target webpage determined according to the URL and the preset field content is the same as the encoding format of the target webpage determined according to the URL and the character string conversion mode.
And step S105, determining the coding format of the target webpage according to the judgment result.
For the above steps, two ways of determining the encoding format of the target webpage may be established, and by comparison, the encoding format of the target webpage determined according to the URL and the preset field content may be determined to be the encoding format of the target webpage determined according to the URL and the preset field content under the condition that the encoding format of the target webpage determined according to the URL and the character string conversion way is determined to be the same as the encoding format of the target webpage determined according to the URL and the preset field content.
In the above embodiment, if it is determined that the encoding format of the target webpage determined according to the URL and the preset field content is different from the encoding format of the target webpage determined according to the URL and the character string conversion method, the encoding format of the target webpage needs to be determined again. Optionally, under the condition that it is determined that the encoding format of the target webpage determined according to the URL and the preset field content is different from the encoding format of the target webpage determined according to the URL and the character string conversion manner, it may also be determined that the encoding format of the target webpage determined according to the URL and the preset field content is the encoding format of the target webpage.
Optionally, determining the encoding format of the target webpage according to the determination result includes: if the judgment results are the same, taking the encoding format of the target webpage determined according to the URL and the preset field content or the encoding format of the target webpage determined according to the URL or the preset character string conversion mode as the encoding format of the target webpage; and if the judgment results are different, taking the coding format of the target webpage determined according to the URL and the preset character string conversion mode as the coding format of the target webpage.
In the embodiment, when the determination result is different, the encoding format of the target webpage determined according to the URL and the preset character string conversion manner may be used as the encoding format of the target webpage.
By the embodiment, the encoding format of the target webpage can be determined according to the URL and the preset field content, the encoding format of the target webpage can also be determined according to the URL and the character string conversion mode, then whether the encoding format of the target webpage determined according to the URL and the preset field content is the same as the encoding format of the target webpage determined according to the URL and the character string conversion mode is judged, and the encoding format of the target webpage is determined according to the judgment result. By the two methods for determining the coding formats, the coding format of the target webpage can be determined more accurately, the efficiency for determining the coding format of the target webpage can be improved correspondingly, and the problem of low efficiency in determining the coding format of the webpage in the related art is solved.
The following are specific examples according to the present application.
In this embodiment, UTF-8 is used as the reference encoding format. Optionally, in this embodiment, the format of the web page code is determined by a character string mode, the web page obtained according to the URL is converted into a character string mode, and then the character string is converted into a byte stream by a GB2312 coding mode; the converted byte stream is then restored to a string-formatted file in UTF-8. And judging whether the Chinese characters exist in the file in the character string format, if so, determining that the encoding format of the webpage is a UTF-8 encoding format, otherwise, determining that the webpage is GBK or GB2312 encoding.
Optionally, the encoding format of the web page is determined by the charset field, and when the encoding format of the web page determined by the charset field is consistent with the determined encoding format of the web page, the encoding format of the web page may be determined.
Through repeated tests, the method has high judgment accuracy rate which basically reaches 98%, is a reverse judgment mode, can be used for judging the coding format of the webpage before crawling of the webpage crawler, and reduces the probability of messy codes.
In the related art, if the coding format of the web page is judged, only a small part of byte streams in the web page are often judged, and the coding format of the web page is not judged according to the full-text file. By the embodiment of the application, the accuracy of judging the webpage coding format can be improved, the coding format is dynamically generated in the crawling process, and a CSN file of the coding format does not need to be configured independently. According to the method and the device, the judgment is carried out through all byte streams of the page and the confirmation is carried out by combining fields of the webpage chase, so that the efficiency of judging the webpage codes is improved.
