The IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) upgrade website platform can upgrade the website of the IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) network to the website of the IPv6 network. The upgraded website pages will have links to other non-upgraded websites, that is, external links. If the external link website does not have an IPv6 network, and the IPv6 client clicks on the external link in the upgraded website, the access will fail.

Therefore, before the IPv6 website returns the webpage to the client, it needs to convert the external link in the page to a certain format, for example, convert the external link domain name www.aaaa.com in the upgraded website www.xxxx.com to www. aaaa.ipv6.xxxx.com, so that IPv6 client users click on the converted external link domain name www.aaaa.ipv6.xxxx.com, they will visit the IPv6 upgrade website platform, and the IPv6 upgrade website platform will proxy access to the external link IPv4 source Website www.aaaa.com, the IPv6 client can successfully access the external link.

However, for non-upgraded websites that do not exist in the pages of the upgraded website, the conversion format can be imitated and faked as converted external links in the upgraded website. Such external links are called illegal external links. For example, there is no website www.bbbb.com in the upgraded website www.xxxx.com page, and the imitation conversion format is converted to www.bbbb.ipv6.xxxx.com. Such external links are illegal external links, and users access illegal external links , the request will be directed to the IPv6 upgrade website platform, and the IPv6 upgrade website platform will proxy access to the IPv4 source site of the illegal external link, thus wasting the resources of the upgrade website platform, and may also visit some malicious websites and cause a security incident on the IPv6 upgrade website . There is no method for intercepting the above-mentioned illegal external links in the prior art.

Based on this, the embodiment of the present invention provides a processing method, device, and electronic device for accessing external link requests, specifically providing a platform for upgrading an IPv4 website to an IPv6 website or converting an IPv6 website to an IPv4 website, intercepting illegal websites forged into The method of accessing external links solves the problem of how to accurately intercept illegal external links in upgrading websites. It can not only intercept illegal websites forged as external links for access, but also ensure the normal access of upgraded websites and legal external links at the same time.

In order to facilitate the understanding of this embodiment, a method for processing a request for accessing an external link disclosed in the embodiment of the present invention is firstly introduced in detail.

Embodiment one:

The embodiment of the present invention provides a processing method for accessing an external link request, which is applied to an upgraded website platform. The client, the upgraded website platform and the designated source station are connected in sequence, and the upgraded website platform is also connected to the upgraded website; the upgraded website platform is provided with an external link Record table, the external chain domain name set in the external chain record table includes: the external chain domain name of the upgraded website and/or the external chain domain name of the designated source site.

Wherein, the upgrading website platform in this embodiment can upgrade an IPv4 website to an IPv6 website, or convert an IPv6 website to an IPv4 website. Therefore, the client, the upgraded website platform and the upgraded website in this embodiment all adopt the IPv6 protocol, and the designated source station adopts the IPv4 protocol; or, the client, the upgraded website platform and the upgraded website all adopt the IPv4 protocol, and the designated source station adopts the IPv6 protocol .

In this embodiment, the upgrading of the website platform to upgrade the IPv4 website to the IPv6 website is taken as an example, which will not be repeated hereafter. The IPv6 upgrade website platform in the present embodiment is deployed between the http (Hyper Text Transfer Protocol, hypertext transfer protocol) designated source station of IPv6 client and IPv4, and the IPv6 upgrade website is a website authorized by the IPv6 upgrade website platform, and the IPv6 client can Access the IPv6 upgrade website through the IPv6 upgrade website platform, and all non-IPv6 upgrade website domain names in the IPv6 upgrade website page.

Based on the above description, referring to the flow chart of a method for processing a request to access an external link shown in FIG. 1 , the method for processing a request to access an external link includes the following steps:

Step S102, receiving the external link access request sent by the client, and determining whether the external link domain name corresponding to the request exists in the external link record table.

The upgraded website platform has an external link record table, which can save the legal external links in the upgraded website to the external link record table. When the request for accessing the external link sent by the client reaches the upgraded website platform, the upgraded website platform can determine whether the external link domain name corresponding to the request exists in the external link record table.

Step S104, if it exists, determine that the request is passed, so that the client accesses the external link domain name corresponding to the request.

If the external link domain name corresponding to the request exists in the external link record table, it means that the external link corresponding to the request is legal and access can be allowed. If the request is confirmed, the client can access the external link domain name corresponding to the request.

For example: when an IPv6 client user accesses an external link website, the upgraded website platform can determine whether the external link domain name corresponding to the request exists in the external link record list, and if it exists in the external link record list, the access is passed.

Step S106, if it does not exist, it is determined that the request is not passed, so that the client does not access the external link domain name corresponding to the request.

If the domain name of the external link corresponding to the request does not exist in the external link record table, it means that the external link corresponding to the request is forged by an illegal website, the request can be rejected, and the request is determined not to pass, and the client cannot access the external link corresponding to the request domain name. In this way, illegal websites are forged to be accessed as external links, and normal access to upgraded websites and legal external links can be guaranteed.

For example: when an IPv6 client user accesses an external link website, the upgraded website platform can determine whether the external link domain name corresponding to the request exists in the external link record list, and if it does not exist in the external link record list, the access is rejected.

The embodiment of the present invention provides a processing method for accessing an external link request. The upgraded website platform receives the external link request sent by the client, and determines whether the external link domain name corresponding to the request exists in the external link record table; if it exists, it is determined that the request passes , the external link domain name corresponding to the client access request; if it does not exist, it is determined that the request fails, and the client does not access the external link domain name corresponding to the request. In this method, it is possible to intercept illegal websites forged as external links for access, and at the same time ensure the normal access of upgraded websites and legal external links.

Embodiment two:

This embodiment provides another method for processing a request to access an external link, which is implemented on the basis of the above-mentioned embodiment. Refer to the flow chart of another method for processing a request to access an external link shown in FIG. 2 , this embodiment The processing method for accessing the external link request in includes the following steps:

Step S202, sending a target request to the upgrade website or the designated source site; receiving a response message sent by the upgrade website or the designated source site based on the target request; and recording the external link domain name corresponding to the response message in the external link record table.

The upgrade website platform in this embodiment can send a target request to the upgrade website or the designated source station, and after receiving the response message sent by the upgrade website or the designated source station based on the target request, record the external link domain name corresponding to the response message To the external chain record table.

For example: after the IPv6 upgrade website platform receives the http response message sent by the IPv6 upgrade website or the IPv4 source site of the legal external link website, it will record all the external link domain names in the http response message into the external link record table, and regard these external link The chain domain name is a legal external chain.

Specifically, in this embodiment, the external link domain name corresponding to the response message may be determined through character string matching; the determined external link domain name corresponding to the response message may be recorded in the external link record table.

In this embodiment, the external link domain name corresponding to the response message can be determined by character string matching, so as to quickly and accurately record the determined external link domain name corresponding to the response message in the external link record table.

In this embodiment, the method for storing and identifying legal external links can be as follows: the external links in websites upgraded from IPv4 to IPv6 are regarded as legal external links, and the external links in websites with legal external links are also regarded as legal external links , and store all legal backlinks in the backlink record table.

For example: the IPv6 upgrade website platform forwards the request sent to the upgrade website or the legitimate external link website to the IPv4 source site. The IPv4 origin site responds to the http response message. After the IPv6 upgrade website platform receives the http response message, it uses the string matching algorithm to find out all the external domain names in the http response message. The IPv6 upgrade website platform adds these external link domain names to the external link domain name record table, thus completing the storage and identification of legal external links.

For example, the IPv6 upgrade website is www.aaaaa.com, and there is an external link domain name www.bbbbb.com in the http response page of its IPv4 origin site. You can add the external link domain name "www.bbbbb.com" to the external link record table, complete the storage of this external link domain name, and mark this external link domain name as a legal external link. Therefore, all external links in the upgraded website www.aaaaa.com can be stored in the external link record table, and the storage of all external link domain names is completed, and all external link domain names are identified as legitimate external links.

In this embodiment, when a user visits a website where IPv4 is upgraded to IPv6, the IPv6 website upgrade platform sends an http request to the IPv4 source station, and when the http response message of the IPv4 source station arrives at the IPv6 upgrade website platform, a character string matching algorithm can be used, Find all external domain names in the http response message, store the external domain names, and identify the external domain names as legitimate external links.

Step S204, receiving the external link access request sent by the client, and determining whether the external link domain name corresponding to the request exists in the external link record table.

Specifically, the external link record table in this embodiment has a red-black tree structure, and each node of the red-black tree structure records an external link domain name. The external chain record table can be realized based on the red-black tree, and the external chain domain name is used as the value of each node of the red-black tree, which can realize fast reading, writing and searching of the external chain domain name. A legal external link domain name is a piece of data in the external link record table, and it is also the value of a node in the red-black tree.

Specifically, in this embodiment, an external link record table based on a red-black tree can be created, and the legal external link domain name is used as the value of each node of the red-black tree, and the read, write and search functions of the external link domain name can be realized. The method provided in this embodiment also includes at least one of the following: find out whether there is an external domain name in the node of the red-black tree structure through the search function; insert the external domain name into the node of the red-black tree structure through the insertion function; Delete the external domain name from the nodes of the red-black tree structure; maintain the balance of the red-black tree structure by adjusting the function.

First, the external link record table class based on the red-black tree can be realized. The value of each node of the red-black tree is a legal external link domain name string. The lookup function is used to find out whether the specified external link domain name exists in the external link record table, actually it is to find whether there is a node whose value is the specified external link domain name in the red-black tree. The insert function is used to save the legal domain name of the external chain in the external chain record table. In fact, the string of the external chain domain name is inserted into the red-black tree as the value of the new node. The delete function is used to delete the specified external link domain name from the external link record table, and actually deletes the node whose value is the specified external link domain name in the red-black tree from the red-black tree. The adjustment function is used to adjust the red-black tree to balance when the insertion or deletion causes the red-black tree saving the external domain name to be unbalanced.

For example: for a piece of data in the external link record table, there is a legal external link domain name "www.xxxx.com" in the upgraded website www.aaaa.com, then the external link domain name string "www.xxxx.com" is used as the external link record A piece of data in the table is also the value of a node in the red-black tree.

Another example: Add an external domain name to the external link record table, add a legal external link domain name "www.xxxx.com" to the external link record table, and actually call the insert function to insert the external chain domain name string "www.xxxx.com" into the red-black tree.

Another example: for the external link record table to search for an external link domain name, the external link record table checks whether there is an external link domain name "www.xxxx.com", and actually calls the search function to find out whether there is a character in the red-black tree whose value is the external link domain name The node of the string "www.xxxx.com".

Another example: delete an external domain name record from the external chain record table, delete the external chain domain name record "www.xxxx.com" in the external chain record table, and actually call the delete function to delete the string of the external domain name in the red-black tree "www.xxxx.com" node.

Step S206, if it exists, determine that the request is passed, so that the client accesses the external link domain name corresponding to the request.

In this embodiment, when the user accesses a suspected legitimate external link domain name, the external link record module can check whether the external link exists in the external link record table, and if the requested external link domain name exists in the external link record table, the access is allowed , confirm that the request is passed, the IPv6 upgrade website platform sends an http request to the IPv4 source site, when the http response message from the IPv4 source site arrives at the IPv6 upgrade website platform, use the string matching algorithm to find all the external domain names in the http response message , record all external chain domain names in the external chain record table, and regard these external chains as legal external chains.

Step S208, if it does not exist, it is determined that the request is not passed, so that the client does not access the external link domain name corresponding to the request.

In this embodiment, when the user accesses a suspected legitimate external link domain name, the external link record module can check whether the external link exists in the external link record table, and if the external link does not exist in the external link record table, the requested external link It is regarded as an illegal external link, and the request is determined to be rejected, and the access is denied. In this way, the forged external links of illegal websites will not be successfully accessed, and the normal access of legal external links can be guaranteed.

For the overall process of judging whether the external link accessed by the user is legal and whether the user's access is passed, you can refer to the schematic diagram of the overall process of a processing method for accessing external link requests shown in Figure 3. After the user's http request arrives, first judge Whether the request is for an IPv6 upgraded website, if it is an IPv6 upgraded website, the external link recording module can store and identify the page as a legal external link, allowing access. If the website is not upgraded for IPv6, it can be judged whether the requested website is an external link website. If the requested website is not an external website, access is denied. If the request is an external link website, it is judged whether the requested external link is legal through the external link recording module. If the requested external link is illegal, access is denied. If the requested external link is legal, the external link recording module can store and identify the page as a legal external link, allowing access.

For the method of storing and identifying a page as a legal external link by the external link recording module, you can refer to the schematic diagram of a method for storing and identifying a page as a legal external link by the external link recording module shown in Figure 4. The IPv6 website upgrade platform can convert the http request Sent to the IPv4 source site, the http response message from the IPv4 source site reaches the IPv6 website upgrade platform, the IPv6 website upgrade platform can use the string matching algorithm to find all external domain names in the http response message, and store these external domain names in the external domain name Record the table and mark it as a legitimate external link.

For the method for the external link recording module to determine whether the requested external link is legal, please refer to the schematic diagram of a method for the external link recording module to determine whether the requested external link is legal as shown in Figure 5. After obtaining the external link domain name requested by http, The requested external domain name can be found in the external chain domain name record table. Determine whether the requested external link domain name exists in the external link domain name record table; if it exists in the external link domain name record table, the requested external link is legal; if it does not exist in the external link domain name record table, the requested external link is invalid.

The above method provided by this embodiment can create a red-black tree-based external link record table, which is used to record all external link domain names in legally upgraded websites and legal external link website pages and mark them as legal external links. When the link request arrives at the upgrade platform, it is judged whether the requested external link domain name exists in the external link record list. If the requested external link domain name exists in the external link record list, the request is a legal external link and the request is allowed. If the link domain name does not exist in the external link record table, the request is an illegal external link, and the request is intercepted.
