Description
Technical Field
The present disclosure relates to the field of network communication technologies, and in particular, to a method and an apparatus for solving a skylight problem.
Background
As IPv4 address resources are depleted, IPv6 networks are becoming increasingly popular in order to accommodate more network access points. At present, the internet is in the transition stage from IPv4 to IPv6, and the internet can use both protocols.
In order to provide a large amount of internal resources and external resources to users, a large amount of internal resource links and external resource links are stored in various service websites. If the first website has been upgraded to support the IPv6 protocol, its internal resources are linked to links corresponding to IPv6 addresses; the IPv4 protocol is still adopted because the second website corresponding to the external resource link is not upgraded; when a client upgraded to the IPv6 protocol accesses the content of the first website through an external resource link provided by the first website, the client responds slowly and the external resource cannot be displayed; the problem that the display window has incomplete pages or partial blank contents due to the contents corresponding to the external resources is a skylight problem.
The first website can adopt the following method to avoid the skylight problem as much as possible.
The first method is as follows: when responding to a request of a client side to generate a response message, a first website converts an external resource link in the response message into a sub-domain name of a master station of a second website (the first website may also be the first website) and generates a rewriting link; when the client triggers the rewriting link, the DNS server returns the request of the client about the external resource to a second website server according to the rewriting link; the second website server requests the external resource of the second website by adopting an IPv4 network according to the external resource link; and after the external resource is obtained, the second website server returns to the client.
The second method is as follows: when responding to a user request and generating a response message, the first website converts an external resource link in the response message into a relative path link; triggering a relative path link at a client to generate a query request to reach a first website server; the first website server requests the external resource of the second website by adopting an IPv4 network according to the external resource link; and after the external resources are obtained, the first website is returned to the client.
The foregoing two methods have the following problems: two methods require the addition of sub-domain name authorization of the master domain name; the more external resource links provided by the first website, the more sub-domain name authorizations which need to be authorized, and the configuration time is increased; the probability of collision between the rewritten link rewritten by the external link and the existing resource link is also increased, resulting in an access error. Some users familiar with the external resource link IPv4 website may have a doubt that the rewritten link is a malicious link after seeing the rewritten link.

Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
The embodiment of the application provides a method for solving the skylight problem, wherein an external resource link corresponding to a second server adopting different IP protocols is replaced by a rewriting link with a domain name serving as an existing domain name of a server according to a specific conversion rule through a special processing step in a first server, so that when the client checks the rewriting link, a corresponding request is returned to the first server, and the first server obtains resources from the second server by adopting another IP protocol.
Fig. 1 is a flowchart of a method for solving a skylight problem according to an embodiment of the present disclosure. As shown in fig. 1, the participants of the method for solving the skylight problem provided by the embodiment of the present application at least include a client and a first server.
In the embodiment of the application, the client is a client only supporting a first IP protocol; the first server is a server that can support both a first IP protocol and a second IP protocol, the first IP protocol and the second IP protocol being incompatible.
In the specific application of the embodiment of the application, the first IP protocol is an IPv6 protocol, and the second IP protocol is an IPv4 protocol; alternatively, the first IP protocol is an IPv4 protocol and the second IP protocol is an IPv6 protocol.
As shown in fig. 1, the method provided by the embodiment of the present application includes steps S101-S107.
S101: and generating and sending a first request message.
As shown in fig. 1, step S101 is performed by the client.
After selecting a resource link (i.e., a hyperlink) associated with a resource in the first server, the client generates a first request message according to the first IP protocol, and sends the first request message. The destination IP address of the first request message is the IP address of the first server, and the first request message is sent to the first server by the called party after being routed by the routing equipment.
The following steps S102-S107 are performed by the first server
S102: and acquiring response data according to the received first request message.
After receiving the first request message, the first server analyzes the first request message according to the first IP protocol to obtain a resource link, and queries a server database according to the resource link to obtain response data associated with the resource link.
In practice, the response data may include text, picture files, audio files, or video files, and may also include hyperlinks. In case the response data comprises hyperlinks, this may be external resource links, i.e. hyperlinks not corresponding to the resource provided by the first server. The external resource link may be a link associated with an external server-provided resource supporting a first IP protocol or may be a link associated with an external server-provided resource supporting a second IP protocol. For convenience, a link associated with a server-provided resource externally supporting the second IP protocol is referred to as a first resource link, and a link associated with a server-provided resource externally supporting the first IP protocol is referred to as a second resource link.
As described above, if the first resource link is sent to the client, and the client generates a request message through the first resource link and sends the request message to the corresponding server, because different IP protocols are configured, the corresponding server cannot parse the message.
S103: it is determined whether the response data includes a first external resource link.
If yes, go to step S104; if not, directly executing step S106.
In this embodiment, in order to implement the step of step S103, a configurable domain name table may be stored in the first server, where the domain name table stores the domain name of a server supporting only the first IP protocol or stores the domain name of a server supporting only the second IP protocol. The first server may match the domain name of the external resource link in the response data with the domain name in the domain name table, and determine whether the response data includes the first external resource link.
S104: a rewritten link is generated that includes the first query parameter.
The first query parameter is all query parameters except the domain name information in the rewriting link.
In step S104, the rule for the first server to generate the rewrite link is: (1) taking a domain name in the first server as a domain name of the rewriting link; a domain name in the first server may be a master domain name thereof or a sub-domain name thereof, which is not limited in this embodiment of the present application. (2) The domain name in the first external resource link is converted to at least a portion of the first query parameters that overwrite the link according to the conversion rules.
According to different forms of the first external resource link, the replacement rules provided by the embodiment of the present application are different, and are divided into the following two cases.
First case
In the first case, the conversion rule comprises a first conversion rule and a second conversion rule; the conditions for adopting the first conversion rule and the second conversion rule are as follows: the first external resource link includes a second query parameter (the second query parameter is the entirety of the first external resource link and is named "second query parameter" to distinguish it from the first query parameter described previously).
At this time, the step of generating the first query parameter includes: (1) the second query parameter in the first external resource link is taken as part of the first query parameter. (2) The domain name in the first external resource link is converted to another portion of the first query parameters.
For example, the first server has a host domain name of www.test.com and is accessed using http protocol. Responding to a first external resource link with a URL (uniform resource locator) of http:// www.a.com/search ═ utf-8& key in data; after the first external resource link is inquired, the first server: (1) directly taking http:// www.test.com/as the domain name of the rewriting link; (2) according to a first conversion rule, taking/search-8 & key (namely, a second query parameter) as a part of the first query parameter; (3) according to a second conversion rule, http:// www.a.com is rewritten to & convert & http & www.a.com. Followed by http:// www.test.com/? ie — utf-8& key & convert & http & www.a.com.
It should be noted that to avoid identifying parts of the content in the first query parameters as domain names, the second conversion rule comprises an identifier of "& convert &" to "&" in the first external resource link.
Second case
In a second case, the conversion rule comprises a third conversion rule; the conditions corresponding to the third conversion rule are: the first external resource section includes a second query parameter.
At this time, the step of generating the first query parameter includes: and converting the domain name of the first external parameter into the first query parameter according to a third conversion rule.
For example, the first server has a host domain name of www.test.com and is accessed using http protocol. Responding to a first external resource link with the URL being http:// www.a.com/, after the first server inquires the first external resource link: (1) directly taking http:// www.test.com/as the domain name of the rewriting link; (2) according to a third conversion rule, http:// www.a.com/is converted into? The format of convert & http & www.a.com. Followed by http:// www.test.com/? change & http & www.a.com.
It should be noted that in order to avoid identifying part of the content in the first query parameter as a domain name, the third conversion rule employs "? convert "/" in the first external resource link to "&" as an identifier.
S105: the first external resource link in the response data is replaced with the overwrite link.
When step S105 is executed, the first server replaces the first external resource link with the replacement link according to the position of the first external resource link in the response data.
In practical implementation, the foregoing steps S102-S105 may be processed in real time for all the first external resource links in the response data.
After steps S102 to S105, all the first external resource links in the response data are replaced with the rewrite link. Execution may then continue with S106.
S106: and generating a first response message according to the response data and sending the first response message.
In step S106, the first server generates a first response packet according to the first IP protocol. The destination IP address of the first response message is the IP address of the client.
In this embodiment, according to the size of the response data, the first server may generate one first response packet or may generate a plurality of first response packets. The destination address of the first response message is the address of the client, and after the first response message is routed by the routing equipment, the first response message can be sent to the client, so that the client can obtain corresponding data.
With reference to the foregoing descriptions of steps S101 to S106, it may be determined that, in the method for solving the skylights according to the solution provided by the embodiment of the present application, when the first external resource link is included in the response data to be sent to the client, the first server forms a rewrite link by using a domain name of the first external resource link as an inquiry parameter corresponding to the domain name of the first server, replaces the first external resource link in the response data with the rewrite link, and then sends the response data to the client in the form of the first response packet.
After receiving the first response message and analyzing the response data, if the client wants to check the external resource corresponding to the first external resource link, the client actually triggers the rewrite link and generates a new request message (the new request message is a second request message in the following text). Since the domain name of the rewritten link is the first server, the newly generated second request message is sent to the first server.
In the embodiment of the present application, the first server has a capability of converting the rewriting link into the first external resource link according to the conversion rule, in addition to converting the first external resource link into the rewriting link. Therefore, the first server can determine the external resource to be acquired by the user terminal.
In the foregoing steps, the sub-domain name authorization of the domain name of the primary station does not need to be added, so that the configuration amount of resources is reduced, and the problem of possible resource link conflict is avoided. Because the hyperlink viewed by the user side is the link corresponding to the domain name of the first server, the first server is the server which is visited by the user in the previous period, and the trust degree of the first server is higher, the problem that the user suspects that the rewriting of the link is a malicious link is basically eliminated.
In the foregoing description, a method for implementing a solution to the skylight problem includes a client and a first server; in the actual method flow, the execution steps of the first server are improved relative to the prior art, and the client can still adopt the prior art scheme. In order to clearly demonstrate the innovation of the embodiment of the present application, the following briefly describes the steps performed by the first server in the embodiment of the present application.
Fig. 2 is a flowchart of a method for solving the skylight problem applied to the first server in the embodiment of the present application. With reference to fig. 1 and 2, the execution steps of the first server include S201-S202.
S201: and acquiring response data according to the received first request message.
S202: it is determined whether the response data includes a first external resource link. If yes, go to S203; if not, directly executing S205.
S203: generating a rewrite link containing the first query parameter;
s204: replacing the first external resource link in the response data with the overwrite link;
s205: and generating a first response message according to the response data and sending the first response message.
The specific implementation of steps S201-S205 can be seen in steps S102-S106, and will not be repeated here.
After receiving the first response message and adopting the first IP protocol to analyze the first winning message to obtain response data, the client may click the rewriting link in the response data to inquire the corresponding resource. Fig. 3 is a flowchart of the operation steps after triggering rewriting the link according to the present application.
In steps S101 to S107, the method for solving the skylight according to the embodiment of the present application further includes steps S301 to S306 as shown in fig. 3.
It should be noted that on the basis of the two parties shown in fig. 1, the method of fig. 3 is carried out with reference to a second server; in addition, as shown in fig. 3, a third server using the first IP protocol may be involved in practical application; since this part is the same as the prior art, the embodiments of the present application will not be described.
The second server is a server that supports only the second IP protocol. Because the client and the second server do not support the same IP protocol, the client generates a request packet requesting the resource according to the resource link associated with the resource in the second server, and the request packet cannot be analyzed by the second server, so the second server cannot directly return the request packet to the client.
S301: and generating a second request message according to the link in the user trigger response data.
Step S301 is performed by the client. When the user at the client end inquires the resources corresponding to the links, the user at the client end is triggered to generate a second request message by clicking the links and other operations.
The link clicked by the user may be the first external resource link, the second external resource link, or the internal resource link.
The domain names of the first external resource link and the internal resource link are both the first server, so that if the link clicked by the user is the two links, the second request message is sent to the first server. The domain name linked with the second external resource is the domain name of other server, and the other server is the server supporting the first IP protocol, so the second request message generated by the client can be directly sent to the other server.
S302: and receiving a second request message sent by the client.
Steps S302-S306 are performed by the first server. In step S302, the first server receives the second request packet and parses the second request packet to obtain the request information therein.
S303: and judging whether the second request message comprises the rewriting link. If yes, go to step S304; if not, go to S305.
When step S303 is executed, the first server may check whether the request information includes a hyperlink by querying the request information; if a hyperlink is included and the domain name of the hyperlink is a specific domain name and the query parameters of the hyperlink include parameters in the conversion rules, the hyperlink is determined to be a rewritten link, in which case 304 is performed.
For example, in conjunction with the foregoing distance, if the domain name of the hyperlink is http:// www.test.com/, and is included in the hyperlink? And if the hyperlink is changed, the hyperlink is judged to be the rewritten link.
S304: and according to the conversion rule, restoring according to the rewritten link to obtain the first external resource link.
The conversion rule in step S304 is the conversion rule for generating the rewrite link described above. The rewritten link is restored to obtain the first external resource link according to the conversion rule, even if the above-mentioned reverse operation of step S104 is performed, which will not be repeated here.
S305: and acquiring the external resource according to the first external resource link.
After the first server acquires the first external resource link, the external resource can be determined through corresponding processing.
In the embodiment of the application, there are various ways of obtaining the external resource according to the first external resource link.
In one particular application, step S305 may include sub-steps S3051-S3052. Correspondingly, the second server performs steps S401-S402.
S3051: and generating a third request message containing the first external resource link according to the second IP protocol and sending the third request message.
In step S3051, after generating the third request packet, the first server sends the third request packet to the network device; wherein the destination IP address of the third request message is the IP address of the second server. The third request message is sent to the second server via the network device route.
After the first server executes S3051, the second server correspondingly executes steps S401-S403.
S401: and after receiving the third request message, acquiring the first external resource link.
In step S401, the second server parses the third request packet according to the second IP protocol to obtain the first external resource link.
S402: and inquiring the external resource according to the first external resource link.
S403: and generating a third response message according to the external resource and sending the third response message.
In step S403, the second server generates a third response packet according to the second IP protocol, and uses the IP address of the first server as the destination IP address of the third request packet. After the third response message is sent, the third response message is sent to the first server through the routing device.
S3052: and receiving a third response message returned by the second server, and analyzing the third return message according to the second IP protocol to obtain the external resource.
And after receiving the third response message, the first server analyzes the third return message through a second IP protocol, and determines that the data in the third request message is the external resource requested by the client.
By adopting the substeps S3051-S3052, the first server can acquire the external resource according to the actual demand of the user.
In another specific application, step S305 may include sub-steps 3053-3056.
S3053: and inquiring whether the local existing resources comprise external resources corresponding to the first external resource link. If yes, executing S3054; if not, executing S3055-S3056.
The local existing resources are resources cached locally for the purpose that the first server has previously acquired from the second server. In some specific applications, some first external resource links are viewed frequently, and in order to improve response efficiency, the first server may cache the external resource corresponding to such first external resource links locally and use the first external resource links as identifiers.
S3054: and acquiring the external resource from the existing resource.
If the external resource corresponding to the first external resource link is cached locally, the first server can directly obtain the external resource.
S3055: and generating a third request message containing the first external resource link according to the second IP protocol so as to send the third request message to the second server.
S3056: and receiving a third response message returned by the second server, and analyzing the third return message according to the second IP protocol to obtain the external resource.
S3055 and S3056 are similar to the S3051-S3052, and detailed description is omitted here, and specific energy contents can be found in the expressions in S3051-3052.
After the execution of the completion S305, the first server may continue to execute step S306.
S306: and generating a second response message according to the external resource and sending the second response message.
In step S306, the first server generates a second response packet according to the first IP protocol, uses the IP address of the client as the destination IP address of the second response packet, and sends the second response packet.
And the second response message can be sent to the client through the route of the routing equipment, and the client obtains the external resource after analyzing the second response message.
By adopting the steps S301-S306, the client acquires the external resource, and the skylight problem is avoided.
In the foregoing embodiment, when the first server generates the rewrite link including the first query parameter in step S104 (or S203), the first server adopts its own domain name as the domain name of the rewrite link. In other embodiments, in executing S104, the first server may further adopt a domain name of a third server as the domain name of the overwriting link. The third server is also a server capable of supporting both the first IP protocol and the second IP protocol, and is configured with the aforementioned conversion rules.
In the case where the domain name of the rewrite link is the third server, the execution subject of the foregoing steps S302-S306 is changed from the first server to the third server. In a specific application of this embodiment, if the first server is a server with a large access amount, in order to reduce the access pressure, some query operations of the client may be performed by the third server by setting the domain name in the rewritten link as the third server in step S104, and then reducing the access amount of the first server.
It should also be noted that, in practical applications, the first server, the second server, and the third server may be a single server, or may be a server system formed by a plurality of actual server architectures.
