Website access system, method and device

Technical Field

The application relates to the field of internet, in particular to a website access system, method and device.

Background

With the increasing number of Internet users, more and more IPv4(Internet Protocol version 4 Internet Protocol version four) addresses are needed, but the IPv4 addresses are fixed, so after the IPv4 addresses are exhausted, IPv6(Internet Protocol version 6 Internet Protocol version six) addresses need to be introduced to replace the IPv4 addresses, but when an IPv6 single-stack user accesses a website with an IPv6 address, the IPv4 external link website in the website cannot be opened, so the problems of access and rewriting of the IPv4 external link need to be solved.

In order to solve the above problems, a method for accessing an IPv4 external link through a NAT64 gateway appears in the related art, but the method is effective for IPv6 single-stack users, and meanwhile, the access experience of dual-stack users is not considered, in the method, the dual-stack users also access the external link through the NAT64, and after a series of processing by the NAT64 gateway, the page is returned to the users, and compared with the case that the user directly accesses the external link, the slow page opening occurs, and the dual-stack user experience is affected.

In order to solve the above problem, a method for running an IPv4 probe service on a client also appears in the related art, and specifically, IP protocol stack information of the client is determined, and whether to perform outer-link rewriting on a request initiated by the client is determined according to the IP protocol stack information. However, in this method, the NAT64 gateway needs to interact with the server twice, and meanwhile, when the NAT64 processes the first request, the NAT64 also needs to process the page returned by the server, which reduces the performance of the NAT64 gateway. In addition, under the condition that the content of the first page is relatively complex, the loading and rendering time of the client is relatively long, and the user experience effect is reduced.

Aiming at the problems that in the prior art, when the NAT64 gateway is adopted to realize that both IPv6 single-stack users and dual-stack users can open IPv4 websites, the gateway and the IPv4 website interact for many times, so that the performance of gateway equipment is reduced and the access time of a client is increased, an effective solution is not provided at present.

For convenience of description, some terms or expressions referred to in the embodiments of the present application are explained below:

IPv 4: internet Protocol version 4(Internet Protocol version 4).

IPv 6: internet Protocol version 4(Internet Protocol version 4) is a next generation IP Protocol designed by the Internet Engineering Task Force (IETF) to replace IPv 4.

NAT64 gateway: a stateful network address and protocol translation technique for enabling network access between IPv4 and IPv6 is typically used when an IPv6 host initiates communication to an IPv4 address.

Outer chain: the out link is a link for importing the own website to another website.

HTTP: request-response protocol.

According to an embodiment of the present application, a website access system is provided.

Fig. 1 is a schematic diagram of a website access system according to an embodiment of the present application. As shown in fig. 1, the system includes:

and the client 10 is in communication connection with the gateway and the server, and is configured to send an access request for a target website to the gateway, and further configured to send a domain name resolution request to the server through the probe page when receiving a probe page returned by the gateway in response to the access request, determine IP protocol stack information of the client according to a domain name resolution result returned by the server, and send an access request carrying the IP protocol stack information for the target website to the gateway again, where the target website communicates with the gateway using IPv 4.

Specifically, the client 10 may use an IPv6 single stack protocol or an IPv4/IPv6 dual stack protocol, when the client 10 uses an IPv6 single stack protocol, and the client 10 accesses a target website, it needs to perform network access through the NAT64 gateway 20, at this time, the NAT64 gateway 20 cannot determine the IP protocol stack information of the client 10, that is, cannot confirm that the client is the IPv6 single stack protocol or the IPv4/IPv6 dual stack protocol, so the NAT64 gateway 20 does not directly access the target website, but returns a preset probe page to the client 10, and automatically initiates a request to the htpdns server 30 through the probe page, performs domain name resolution on a public network of a certain IPv4 protocol, and returns a domain name resolution result, where the htpdns server 30 is a server that performs domain name resolution using the HTTP protocol, instead of the existing UDP-based DNS protocol, and the htpdns server 30 returns the domain name resolution result to the client 10 through the probe page, the IP protocol stack information of the client 10 can be determined according to the resolution result, for example, when the domain name resolution result is the domain name corresponding to the accessed public network, it is determined that the client 10 is the IPv4/IPv6 dual stack protocol, and if the returned resolution result is empty, that is, it cannot be resolved, it is determined that the client 10 is the IPv6 single stack protocol.

It should be noted that after the IP protocol stack information of the client 10 is confirmed through the probe page, the NAT64 gateway 20 may identify the IP protocol stack information of the client 10 when the client 10 accesses the website next time by setting the identifier, and quickly determine whether the client 10 is an IPv4/IPv6 dual stack or an IPv6 single stack according to the identifier of the client 10, where the Cookie may be used as the identifier for distinguishing the IP protocol stack information of the client 10. For example, when the client 10 is an IPv4/IPv6 dual stack, the Cookie value of the client 10 is set to 1; when the client 10 is an IPv6 single stack, the Cookie value of the client 10 is set to 0. By setting the Cookie value, it can be ensured that the Cookie identifier is carried when the client 10 accesses all websites before the client 10 closes the browser, and the NAT64 gateway 20 can quickly determine the IP protocol stack information of the client 10 according to the Cookie identifier of the client 10, determine the return mode of the website accessed by the client 10, and quickly access the target website by the client 10.

And the gateway 20 is in communication connection with the client, and is configured to receive an access request of the client for the target website, return the detection page to the client when the access request is analyzed to not carry the IP protocol stack information of the client, and return the web page content of the target website to the client when the access request carries the IP protocol stack information of the client.

Specifically, the gateway 20 may be a NAT64 gateway, which is used to implement network access between IPv4 and IPv6, and is generally used when an IPv6 host initiates communication to an IPv4 address. The NAT64 gateway 20 will confirm whether there is an identifier corresponding to the IP protocol stack information in the client 10 when receiving an access request from the client 10 to a target website, if there is no identifier, return a preset probe web page to the client 10, determine the IP protocol stack information and add the identifier, and identify the identifier corresponding to the IP protocol stack information in the access request from the client 10 to the target website, and the NAT64 gateway 20 will quickly determine the IP protocol stack information of the client 10 according to the identifier of the client 10, determine the return mode of the website accessed by the client 10, and quickly access the target website by the client 10.

And the server 30 is in communication connection with the client, and is used for performing domain name resolution on the public network which performs communication by using the IPv4 under the condition of receiving a domain name resolution request sent by the client through the detection page, and returning a domain name resolution result to the client.

Specifically, the server 30 may be an httpdns server, where httpdns is a domain name resolution using HTTP protocol, instead of the existing UDP-based DNS protocol. The client 10 directly sends the domain name resolution request to the httpdns server 30 through the probe page, and the httpdns server performs domain name resolution on the public network of any IPv4 protocol, returns the domain name resolution result to the client 10, and confirms the IP protocol stack information of the client 10. After confirming the IP protocol stack information of the client 10, an identifier is set for the client 10, so that when the client 10 accesses a subsequent website, the NAT64 gateway 20 can quickly determine the IP protocol stack information of the client 10.

The website access system provided in the embodiment of the application is communicatively connected to a gateway and a server through a client 10, and is configured to send an access request for a target website to the gateway, and further configured to send a domain name resolution request to the server through a detection page under the condition that the detection page returned by the gateway in response to the access request is received, determine IP Protocol stack information of the client according to a domain name resolution result returned by the server, and send an access request carrying the IP Protocol stack information for the target website to the gateway again, where the target website communicates by using IPv4(Internet Protocol version 4 Internet Protocol fourth edition); the gateway 20 is in communication connection with the client, and is configured to receive an access request of the client for a target website, return a detection page to the client when the access request is analyzed to not carry IP protocol stack information of the client, and return web page content of the target website to the client when the access request carries the IP protocol stack information of the client; and the server 30 is in communication connection with the client, and is used for performing domain name resolution on the public network which performs communication by using the IPv4 under the condition of receiving a domain name resolution request sent by the client through the detection page, and returning a domain name resolution result to the client. The problems that when the NAT64 gateway is adopted to realize that both IPv6 single-stack users and dual-stack users can open IPv4 websites, the gateway interacts with the IPv4 website for multiple times, so that the performance of gateway equipment is reduced, and the access time of a client is increased are solved. When the client accesses the IPv4 website for the first time, the effect of enabling the client to access the target webpage more quickly while improving the performance of gateway equipment is achieved by returning to the preset detection page in the NAT64 gateway and judging the IP protocol stack information of the client through the detection page.

According to an embodiment of the present application, there is provided a website access method. Fig. 2 is a flowchart of a website access method according to an embodiment of the present application. As shown in fig. 2, the method includes:

step S201, a first access request is sent to a gateway, and a detection page returned by the gateway in response to the first access request is obtained, wherein the first access request is used for requesting to access a target website, the target website is communicated by adopting IPv4, the first access request does not carry IP protocol stack information of a client, and the detection page is used for detecting the IP protocol stack information of the client.

Specifically, the gateway may be a NAT64 gateway, which is used to implement network access between IPv4 and IPv6, and is generally used when an IPv6 host initiates communication to an IPv4 address. When the client accesses the target website for the first time, the NAT64 gateway detects whether the client access request has an identifier corresponding to the IP protocol stack information of the client, and when the client access request has no identifier, the NAT64 returns a probe page to the client for acquiring the IP protocol stack information of the client and adding the identifier corresponding to the IP protocol stack information to the client.

It should be noted that the probe page is simple, the content to be loaded is less, the browser rendering is not required, the user does not need to perform interactive operation when the client uses the probe page, the probe page can enable the client to automatically initiate a request to the httpdns server, set cookies for identifying single and double stacks of the client according to a return result, and automatically initiate a second request to the NAT64 to complete the second access to the target website.

Step S203, sending a domain name resolution request to a server through a detection page, acquiring a domain name resolution result returned by the server in response to the domain name resolution request, and determining IP protocol stack information of a client according to the domain name resolution result, wherein the server is used for performing domain name resolution on a public network, and the public network adopts IPv4 for communication.

Specifically, the detection page automatically initiates a request to an httpdns server, performs domain name resolution on a public network of an IPv4 protocol, and returns a domain name resolution result, where the httpdns server is a server that performs domain name resolution using an HTTP protocol, instead of the existing UDP-based DNS protocol, the httpdns server returns the domain name resolution result to the client through the detection page, and can determine the IP protocol stack information of the client according to the resolution result, for example, when the domain name resolution result is a domain name corresponding to the accessed public network, it is determined that the client is an IPv4/IPv6 dual stack protocol, and if the returned resolution result is empty, that is, it is impossible to resolve, it is determined that the client is an IPv6 single stack protocol.

Step S205, sending a second access request to the target website to the gateway, and acquiring the web page content of the target website returned by the gateway in response to the second access request, where the second access request is used to request to access the target website, and the second access request carries the IP protocol stack information of the client.

Specifically, after the IP protocol stack information of the client is confirmed, the detection page adds an identifier to the client, and when the client automatically accesses the target website for the second time through the detection page, the NAT64 gateway recognizes the identifier of the client and returns the target website according to the identifier, thereby achieving the effect of quickly accessing the target website by the client.

According to the website access method provided by the embodiment of the application, a first access request is sent through a gateway, and a detection page returned by the gateway in response to the first access request is obtained, wherein the first access request is used for requesting to access a target website, the target website is communicated by adopting IPv4, the first access request does not carry IP protocol stack information of a client, and the detection page is used for detecting the IP protocol stack information of the client; sending a domain name resolution request to a server through a detection page, acquiring a domain name resolution result returned by the server in response to the domain name resolution request, and determining IP protocol stack information of a client according to the domain name resolution result, wherein the server is used for performing domain name resolution on a public network, and the public network adopts IPv4 for communication; and sending a second access request to the target website to the gateway, and acquiring webpage content of the target website returned by the gateway in response to the second access request, wherein the second access request is used for requesting to access the target website, and the second access request carries the IP protocol stack information of the client. The problems that when the NAT64 gateway is adopted to realize that both IPv6 single-stack users and dual-stack users can open IPv4 websites, the gateway interacts with the IPv4 website for multiple times, so that the performance of gateway equipment is reduced, and the access time of a client is increased are solved. When the client accesses the IPv4 website for the first time, the effect of enabling the client to access the target webpage more quickly while improving the performance of gateway equipment is achieved by returning to the preset detection page in the NAT64 gateway and judging the IP protocol stack information of the client through the detection page.

Optionally, in order to determine the IP protocol stack information of the client, in the website access method provided in the embodiment of the present application, determining the IP protocol stack information of the client according to the domain name resolution result includes: determining that the IP protocol stack information of the client is a double stack under the condition that the domain name resolution result is not empty; and under the condition that the domain name resolution result is empty, determining that the IP protocol stack information of the client is an IPv6 single stack.

Specifically, after receiving a domain name resolution result returned by the probe page, the client may determine, through the resolution result, the IP protocol stack information of the client according to the probe page, for example, when the domain name resolution result is a domain name corresponding to an accessed public network, it is determined that the client is an IPv4/IPv6 dual stack protocol, and if the returned resolution result is empty, that is, it cannot be resolved, it is determined that the client is an IPv6 single stack protocol.

After the IP protocol stack information of the client is judged, the identification addition can be carried out according to the judgment result, for example, when the client is an IPv4/IPv6 dual stack, the Cookie value of the client is set to be 1; when the client is an IPv6 single stack, the Cookie value of the client is set to 0. The NAT64 gateway can determine the IP stack information of the client through the Cookie identifier.

Optionally, in order to store the IP protocol stack information of the client after the IP protocol stack information of the client is confirmed, in the website access method provided in this embodiment of the application, before sending a second access request to the target website to the gateway and acquiring the web page content of the target website returned by the gateway according to the second access request, the method further includes: and storing the IP protocol stack information of the client in a local terminal of the client.

Specifically, after the client determines the IP protocol stack information of the client through the probe page, the IP protocol stack information of the client may be stored in the local terminal in an identification manner, and when a different IPv4 website is accessed next time, the determined identification is directly used to mark the IP protocol stack information of the client, and the probe page is not required to be used to determine the IP protocol stack information of the client again.

Optionally, in order to enable the client to quickly access the target website and the external link in the target website, in the website access method provided in the embodiment of the present application, the web page content of the target website is obtained as the original content when the IP protocol stack information carried in the second access request is a dual stack; and under the condition that the IP protocol stack information carried in the second access request is an IPv6 single stack, adjusting the acquired link in the webpage of the target website to a link corresponding to IPv 6.

Specifically, the client reflects the client IP protocol stack information by setting the Cookie identifier, and after the NAT64 gateway receives an access request from the client to the target website, the Cookie identifier in the request is analyzed to confirm the client IP protocol stack information. If the client is identified to be an IPv4/IPv6 dual-stack client, the client can directly access the target website through IPv6, even if the external link in the target website uses an IPv4 network, the client can still access through the IPv4 network in the dual stack, and the NAT64 gateway does not need to rewrite the external link of the request initiated by the client. If the client is identified to be the IPv6 single stack client, the client can only access the target website through the IPv6, and if the external link in the target website uses the IPv4 network, the client cannot normally access the website, so that the NAT64 gateway needs to rewrite the external link of the target website where the IPv6 single stack client initiates the access request, so that the client can access the external link in the target website through the IPv 6.

According to an embodiment of the present application, another website access method is provided. Fig. 3 is a flowchart of another website access method provided in an embodiment of the present application. As shown in fig. 3, the method includes:

step S301, receiving a first access request sent by the client, and returning a detection page to the client, wherein the first access request is used for requesting to access a target website, the target website adopts IPv4 for communication, and the detection page is used for detecting IP protocol stack information of the client.

Specifically, when receiving a first access request to a target website initiated by a client, the NAT64 gateway determines whether the client carries an identifier corresponding to IP protocol stack information, returns a preset detection webpage to the client if the client does not carry the identifier, and determines the IP protocol stack information of the client through the detection webpage.

Step S303, receiving a second access request sent by the client after determining the IP protocol stack information through the detection page, and returning the webpage content of the target website to the client, wherein the second access request is used for requesting to access the target website, and the second access request carries the IP protocol stack information of the client.

Specifically, after the detection page confirms the IP protocol stack information of the client, the identifier corresponding to the IP protocol stack information is added to a second access request of the client to the target website, the NAT64 gateway analyzes the second access request, when the identifier capable of identifying the IP protocol stack information of the client is analyzed, the NAT64 gateway determines the IP protocol stack information of the client quickly according to the identifier, determines the returning mode of the website accessed by the client, and performs quick access of the client to the target website.

According to the website access method provided by the embodiment of the application, a first access request sent by a client is received, and a detection page is returned to the client, wherein the first access request is used for requesting to access a target website, the target website is communicated by adopting IPv4, and the detection page is used for detecting IP protocol stack information of the client; and receiving a second access request sent by the client after the client determines the IP protocol stack information through the detection page, and returning the webpage content of the target website to the client, wherein the second access request is used for requesting to access the target website and carries the IP protocol stack information of the client. The problems that when the NAT64 gateway is adopted to realize that both IPv6 single-stack users and dual-stack users can open IPv4 websites, the gateway interacts with the IPv4 website for multiple times, so that the performance of gateway equipment is reduced, and the access time of a client is increased are solved. When the client accesses the IPv4 website for the first time, the effect of enabling the client to access the target webpage more quickly while improving the performance of gateway equipment is achieved by returning to the preset detection page in the NAT64 gateway and judging the IP protocol stack information of the client through the detection page.

Optionally, in order to quickly confirm the IP protocol stack information of the client, in the website access method provided in the embodiment of the present application, before receiving the first access request sent by the client and returning the probe page to the client, the method further includes: establishing communication connection with the detection page, and setting a trigger rule of the detection page, wherein the trigger rule is as follows: and under the condition that the access request of the client does not carry the IP protocol stack information of the client, interrupting the access request and returning a detection page to the client.

Specifically, before the client accesses the target website, a preset probe page needs to be connected with the NAT64 gateway, and a trigger rule of the probe page is set, for example, an identifier corresponding to the IP protocol stack information of the client that is not recognized by the NAT64 gateway is used as the trigger rule, when the NAT64 gateway does not recognize the identifier corresponding to the IP protocol stack information of the client, the rule is triggered, the client is interrupted from accessing the target website, the probe page is returned to the client, the IP protocol stack information of the client is confirmed, and the identifier corresponding to the IP protocol stack information of the client is set.

Optionally, in order to access the target website through the NAT64 gateway, in the website access method provided in this embodiment of the application, after receiving the second access request sent by the client, the method further includes: and establishing communication connection with the target website and acquiring the webpage content of the target website.

Specifically, when the client uses the IPv6 network, if the target website is the IPv4 website, it is necessary to perform the conversion from IPv6 to IPv4 network access through the NAT64 gateway, so it is necessary to connect the NAT64 gateway to the target website to obtain the web page content of the target website, and rewrite the external link in the target website according to the IP protocol stack information of the client.

Optionally, in order to quickly confirm the IP protocol stack information of the client, in the website access method provided in the embodiment of the present application, returning the web page content of the target website to the client includes: acquiring IP protocol stack information carried in the second access request; when the IP protocol stack information is a double stack, returning the webpage content of the target website to the client; and when the IP protocol stack information is an IPv6 single stack, adjusting the link in the webpage in the target website to the link corresponding to the IPv6 to obtain an adjusted webpage, and returning the adjusted webpage to the client.

Specifically, the client reflects the client IP protocol stack information by setting the Cookie identifier, and after the NAT64 gateway receives an access request from the client to the target website, the Cookie identifier in the request is analyzed to confirm the client IP protocol stack information. If the client is identified to be an IPv 4/dual-stack client, the client can directly access the target website through IPv6, even if the external link in the target website uses an IPv4 network, the client can still access through the IPv4 network in the dual stack, and the NAT64 gateway does not need to rewrite the external link of the request initiated by the client. If the client is identified to be the IPv6 single stack client, the client can only access the target website through the IPv6, and if the external link in the target website uses the IPv4 network, the client cannot normally access the website, so that the NAT64 gateway needs to rewrite the external link of the target website where the IPv6 single stack client initiates the access request, so that the client can access the external link in the target website through the IPv 6.

An embodiment of an alternative website access method is provided below, and fig. 4 is a flowchart of an alternative website access method provided according to an embodiment of the present application, as shown in fig. 4:

the client initiates a first access request to a target website to the NAT64, the NAT64 gateway analyzes the request sent by the client, and no identifier of IP protocol stack information of the client is found, so the NAT64 gateway returns a detection webpage to the client, the client automatically sends the access request to the httpdns server through the detection webpage, the httpdns server carries out domain name analysis on any IPv4 network and returns an analysis result of the client, the detection webpage judges the IP protocol stack information of the client through the returned result, a label corresponding to the IP protocol stack information is stored in a local terminal, and a representation is added in the access request and sent to the NAT64 gateway when the client accesses the website.

It should be noted that, when the client is an IPv4/IPv6 dual-stack client, the client may directly access the target website through the NAT64 gateway, even if the external link in the target website uses an IPv4 network, the client may still access through the IPv4 network in the dual stack, and the NAT64 gateway does not need to rewrite the external link of the request initiated by the client; when the client is an IPv6 single-stack client, the client can only access a target website requested by the NAT64 gateway through IPv6, when an external link in the target website has an IPv4 network, the NAT64 gateway needs to rewrite the external link of the target website of which the IPv6 single-stack client initiates an access request, and at the moment, the client can directly access the external link in the target website through IPv6, so that the aim of quickly accessing the external link in the target website by the client is fulfilled.

It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
