Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
With the development and demand of network technology, websites compatible with the IPv4/IPv6 protocol are accessed by more and more users, however, network modification using the dual stack technology or the translation technology is prone to have a blank window when a client accesses the network, and more so, when a link referenced by the modified website is not modified, the blank window is often called a "skylight", and the problem of the "skylight" is caused by a failure of accessing an out-link URL (Uniform resource locator) resource. For example, when a content page of a website a supporting the IPv6 protocol refers to a picture or other resources of a website B that does not support the IPv6 protocol, when an IPv6 client accesses the content of the website a, a DNS (Domain Name System) server is used to resolve the IPv6 address of the website a, and the website a server interacts with the IPv6 protocol to obtain a response page, when the IPv6 client analyzes that the picture or other resources of the website a needs to be fetched, the DNS server will also resolve the IPv6 address of the B first, because the website B does not complete the IPv6 modification, at this time, the IPv6 address cannot be resolved or the IPv6 address protocol fails to access the website B, and the IPv6 client fails to obtain the picture or resources of the website B, which causes some blank windows to appear when the client such as a browser displays the website a page, which is called "skylights". In the "skylights" problem example described above, the picture or other resource URL of website B contained in a is referred to as the out-link URL for original website a. I.e., the out-link URL refers to the URL of a domain name chain of a non-web content provider.
At present, the common method for solving the blank window solves the problems by rewriting the domain name of the out-link website accessed by the user, but the method increases unnecessary translation in the communication process of the network, prolongs the communication time and reduces the use experience of the user. Based on this, the method, the apparatus and the protocol conversion server for external link URL resource invocation provided in the embodiments of the present invention can alleviate the above technical problems.
To facilitate understanding of the embodiment, a detailed description is first given to a method for out-link URL resource invocation disclosed in the embodiment of the present invention.
The first embodiment is as follows:
the embodiment of the invention provides a method for calling an external link URL (Uniform resource locator) resource, which is applied to a protocol conversion server, wherein the protocol conversion server is a machine simultaneously having IPv6 and IPv4 addresses and protocol processing capacity, is deployed between a client and a source station server to play an agent role, is provided with seven layers of agent service software, and can communicate with two ends of an agent by using an IP (Internet protocol) protocol supported by an opposite end; the source site server is a web site content server that provides content service responses and may communicate with the protocol translation server using the supported IP address protocol.
In a specific implementation, as shown in fig. 1, a flowchart of a method for out-link URL resource invocation is provided, where the method includes the following steps:
step S102, identifying a first protocol stack used by a client and identifying a second protocol stack supported by an external link URL in page response content of a response client;
specifically, when a client accesses an HTTP:// www.abc.com/page, a DNS server resolves www.abc.com address to a Protocol conversion server, and the client sends an HTTP (Hyper text transport Protocol) request to the Protocol conversion server through a first Protocol stack, wherein the HTTP request comprises HTTP:// www.abc.com/; after receiving the request, the protocol conversion server forwards the http:// www.abc.com/returns to the server of the source station where www.abc.com is located; www.abc.com the source station server returns page response content to the protocol conversion server after receiving http:// www.abc.com/request, therefore, the protocol conversion server can identify the second protocol stack supported by the external link URL in the response page content sent by the client and the source station server.
Step S104, judging whether the first protocol stack is consistent with the second protocol stack;
step S106, if not, the first-level domain name of the outer-link URL and the whole domain name string are rewritten by utilizing a preset rewrite rule, and the rewritten page response content is sent to the client, wherein the rewritten outer-link URL can be resolved to the protocol conversion server through the domain name;
preferably, if the first protocol stack used by the client identified by the protocol conversion server is IPv6, and the identified out-link URL address www.v4exlink.com is an out-link supporting only IPv4, the out-link URL address www.v6exlink.com is an out-link supporting IPv 6; because the protocol stack of the out-link URL address www.v6exlink.com is the same as that of the client, the out-link URL address www.v6exlink.com does not need to be processed and can be directly accessed by the IPv6 client; the protocol stack of the out-link URL address www.v4exlink.com is different from that of the client, so the first-level domain name of the out-link URL and the whole domain name string need to be rewritten by a preset connection character string rewriting rule, for example, the IPv4 out-link URL address www.v4exlink.com can be rewritten to www.v4exlink.exl.ipv6.abc.com, and then the protocol conversion server sends the rewritten page response content to the client.
Step S108, receiving an external link URL calling request which is sent by the client and contains rewritten page response content;
and step S110, acquiring the resource of the external link URL according to the external link URL calling request.
Specifically, after receiving http:// www.abc.com/page response content sent by a protocol conversion server, a client analyzes and shows that the page also needs to load an external link URL www.v4exlink.exl.ipv6.abc.com, the IPv6 client requests a DNS server to analyze an IPv6 address of www.v4exlink.ex1.ipv6.abc.com, the analyzed address is the protocol conversion server, the IPv6 client sends www.v4exlink.exl.ipv6.abc.com external link URL calling request to the protocol conversion server based on an IPv6 protocol, and resources of the external link URL are obtained according to the external link URL calling request.
The method for calling the external link URL resource provided by the embodiment of the invention can identify a first protocol stack used by the client and identify a second protocol stack supported by the external link URL in the page response content of the response client; judging whether the first protocol stack is consistent with the second protocol stack; if not, utilizing a preset rewriting rule to rewrite the primary domain name of the external link URL and the whole domain name string, and sending the rewritten page response content to the client; wherein, the rewritten outer link URL can be resolved to the protocol conversion server through the domain name; receiving an external link URL (uniform resource locator) calling request which is sent by a client and contains rewritten page response content; acquiring the resource of the external link URL according to the external link URL calling request; the first-level domain name of the out-link URL and the whole domain name string are rewritten, so that the out-link URL is placed under the domain name of the accessed website, the problem of blank windows is effectively solved, the phenomenon that unnecessary translation is increased due to rewriting of the domain name of the out-link website accessed by the user is effectively relieved, the communication time is shortened, and the use experience of the user is improved.
Further, the second protocol stack supported by the out-link URL in the page response content of the identification responding client in step S106 can be implemented by steps 11 to 13:
step 11, detecting whether an address and a port corresponding to an external link URL work normally;
specifically, if the source station server responds to the HTTP request of the protocol conversion server, and returns a status code of 200 or 302, the address and the port operate normally, and the other status codes indicate that the address and the port operate abnormally.
Step 12, if yes, calling a DNS server to inquire the record information supported by the external link URL;
and step 13, determining a second protocol stack supported by the external link URL according to the record information.
During specific implementation, if the record information supported by the external link URL is first record information, wherein the first record information is an A record, determining that a second protocol stack supported by the external link URL is an IPv4 protocol stack; and if the record information supported by the external link URL is second record information, wherein the second record information is an AAAA record, determining that the second protocol stack supported by the external link URL is an IPv6 protocol stack.
In particular implementation, fig. 2 shows a flowchart of another method for out-link URL resource invocation, which includes the following steps:
step S201, identifying a first protocol stack used by a client and identifying a second protocol stack supported by an external link URL in page response content of a response client;
step S202, storing the identified second protocol stack into an external link protocol stack type cache database unit;
during specific implementation, an external link protocol stack type cache database unit is arranged in the protocol conversion server, and the detection result of the external link can be cached and recorded in the external link protocol stack type cache database unit, for example, the external link URL address www.v4exlink.com can record that the external link is an IPv4 protocol stack external link, and the external link URL address www.v6exlink.com can record that the external link is an IPv6 protocol stack external link; the same external link domain name for upgrading the website through the same protocol conversion server can directly inquire and respond through an external link protocol stack type cache database unit without repeated DNS server inquiry, thereby improving the access speed of a user. The buffering time of the external link protocol stack type buffer database unit can be independently set for different external link websites, and the buffering time of the external link protocol stack type buffer database unit is not limited in this embodiment.
Step S203, judging whether the first protocol stack is consistent with the second protocol stack;
step S204, if not, the first-level domain name of the outer-link URL and the whole domain name string are rewritten by utilizing a preset rewrite rule, and the rewritten page response content is sent to the client, wherein the rewritten outer-link URL can be resolved to the protocol conversion server through the domain name;
step S205, receiving an external link URL calling request containing rewritten page response content sent by a client;
step S206, acquiring resources of the external link URL according to the external link URL calling request;
specifically, the address of the out-link URL is determined through the out-link URL calling request; the method comprises the following steps that an external link URL calling request is restored according to a preset restoring rule; and the calling DNS server analyzes the restored external link URL calling request to determine a source station address corresponding to the external link URL. And then, acquiring the resource of the external link URL according to the address of the external link URL, specifically, sending the external link URL call request subjected to the reduction processing to the source station address by using a protocol stack corresponding to the source station address so as to acquire the resource of the external link URL responding to the external link URL call request subjected to the reduction processing.
And step S207, sending the resource of the out-link URL to the client for displaying by using the protocol stack corresponding to the first protocol stack.
Specifically, the protocol conversion server sends the resource of the out-link URL to the client for page display by using the IPv6 protocol stack. In this embodiment, the method for the protocol conversion server to process the HTTP request from the IPv4 client to invoke the IPv6/IPv4 out-link URL address is the same as the above, and will not be described herein again.
