Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the invention provides a method for redirecting a website, wherein an execution main body of the method can be network equipment connected with a terminal, such as a router, a repeater, a switch and the like, and the terminal can be a mobile phone, a tablet computer, a computer and the like. The network device may be provided with a processor, a memory, a transceiver, and the like, where the processor may be used for processing in the process of redirecting a website, the memory may be used for data required and generated in the process of redirecting a website, and the transceiver may be used for receiving and sending messages, and the like. In this embodiment, a network device is taken as an example to describe the scheme in detail, and other situations are similar to the above, and the description of this embodiment is not repeated.
As shown in fig. 1, the processing flow of the method may include the following steps:
In the implementation, a user wants to use the terminal to access a certain website on the internet, a browser installed in the terminal can be opened, the terminal can display a main interface of the browser, and a website input box and corresponding search options are displayed in the main interface. The user may input a website address of a website to be visited in the website address input box, where the website address refers to a domain name, then the user may click a search option, the terminal may receive a click instruction of the search option, and the terminal may obtain a main domain name (which may be referred to as a domain name of a website to be visited later) in the website address input by the user, where the website address is www.taotao.com/u/1234.htm, and the main domain name is www.taotao.com. Then, a Domain Name System (DNS) query request is sent to the router, and the DNS query request carries the Domain Name of the website to be accessed.
It should be noted that, if the above-mentioned terminal is a computer, after the user opens the browser, the website input box is at the position where the website of the current interface is displayed. If the terminal is a mobile phone, the website input box is the search input box after the user opens the browser.
And 103, if the preset website redirection condition is met, the router sends a preset IP address to the terminal.
Among them, a preset IP (Internet Protocol) address may be set by a technician and stored in a router, such as 1.125.125.254. Preset website redirection conditions may also be set by a technician and stored in a router, such as the router not accessing the network.
In implementation, a technician sets a kernel hook function in a router, and the kernel hook function can be added to a thread for executing message forwarding, and is used for intercepting and identifying a received message. When the router receives a DNS query request sent by a terminal, the kernel hook function may intercept the DNS query request and identify content in the message. If the preset website redirection condition is met, the preset IP address can be obtained, and then the preset IP address is sent to the terminal.
It should be noted that the function for executing message interception and recognition is a kernel hook function, and any function that can be used for executing message interception and recognition is applicable to the embodiment of the present invention, which is not limited in the embodiment of the present invention.
And 104, the terminal receives the preset IP address sent by the router and sends a webpage acquisition request to the router.
In implementation, after receiving a preset IP address sent by a router, a terminal may send a web page acquisition request to the router, where the web page acquisition request may be an http service request, and carries the preset IP address and a GET (GET) identifier.
And 105, when a webpage acquisition request sent by the terminal is received, if the IP address carried in the webpage acquisition request is a preset IP address, the router acquires the address of the pre-stored redirection website.
Wherein, the address of the redirection website can be stored in the router in advance.
In implementation, after the router receives a webpage acquisition request sent by the terminal, the thread where the kernel hook function is located in the router can intercept and identify the webpage acquisition request, and if the IP address carried in the webpage acquisition request is a preset IP address, the router can acquire a prestored website of the redirection website.
In addition, if the IP address carried in the web page obtaining request is the preset IP address, it may be further determined whether the identifier in the web page obtaining request is a GET identifier, and if the identifier is a GET indication, a pre-stored address of the redirection website may be obtained.
Optionally, the address of the redirection website is a domain name and an IP address.
And 106, the router sends a redirection message to the terminal, wherein the redirection message carries the address of the redirection website.
Wherein the redirection message is an http302 redirection message.
In implementation, after acquiring the address of the redirection website, the router may send a redirection packet to the terminal, where the redirection packet carries the address of the redirection website. For example, the address of the redirection website is IP address 10.10.10.10, and the redirection packet may be as follows:
“HTTP/1.1 302Moved Temporarily\r\n"
"Server:boa 1.1\r\n"
"Date:Sat,21Dec 2009 12:00:00GMT\r\n"
"Connection:close\r\n"
"cache-Control:no-cache\r\n"
"Content-Type:text/html\r\n"
"Location:10.10.10.10\r\n"
"<html><body><br><br></body></html>\r\n”
and step 107, the terminal receives the redirection message and accesses the address of the redirection website carried in the redirection message.
In implementation, after receiving the redirection packet sent by the router, the terminal may access the redirection website by using the address of the redirection website carried in the redirection packet, and the detailed processing procedure is described in detail later.
As shown in fig. 2, if the preset website redirection condition is that the router does not access the network, the execution flow of the embodiment of the present invention may be as follows:
The processing procedure is the same as that of step 101, and is not described herein again.
The processing procedure is the same as that of step 102, and is not described here again.
Step 203, if it is detected that the device does not access the network, a preset IP address is sent to the terminal.
Where the preset IP address may be set by a technician and stored in the router, such as 1.125.125.254.
In implementation, a technician sets a kernel hook function in a router, and the kernel hook function can be added to a thread for executing message forwarding, and is used for intercepting and identifying a received message. When the router receives a DNS query request sent by a terminal, the kernel hook function may intercept the DNS query request and identify content in the message. If the device is detected to be incapable of forwarding the DNS query request, the device is determined not to be accessed to the network, a preset IP address can be obtained, and then the preset IP address is sent to the terminal. After receiving the preset IP address sent by the router, the terminal may send a web page acquisition request to the router, where the web page acquisition request may be an http service request, and carries the preset IP address and GET (acquisition) identifier.
It should be noted that the function for executing message interception and recognition is a kernel hook function, and any function that can be used for executing message interception and recognition is applicable to the embodiment of the present invention, which is not limited in the embodiment of the present invention.
In step 204, the terminal receives the preset IP address sent by the router.
The processing is the same as that in step 104, and is not described here again.
In implementation, after receiving a preset IP address sent by a router, a terminal may initiate a TCP (Transmission Control Protocol) connection to a device corresponding to the preset IP, specifically, a TCP SYN (synchronization) message may be sent to the router, after receiving the TCP SYN message sent by the terminal, the router determines that the IP address is the preset IP address, and may send a TCP SYN + ACK (acknowledgement character) message to the terminal, after receiving the TCP SYN + ACK message sent by the router, the terminal may send a TCP ACK message to the router, and then send a web page acquisition request, which may be an http service request, which carries the preset IP address and a GET (GET) identifier.
In implementation, after the router receives a web page acquisition request sent by the terminal, the thread where the kernel hook function is located in the router can intercept and identify the web page acquisition request, and if the IP address carried in the web page acquisition request is a preset IP address, the router can acquire a pre-stored website address of a redirection website, wherein the pre-stored website address of the redirection website is a website address of a network connection interface and can be a domain name or an IP address.
The technical personnel prestores the network connection interface corresponding to the website of the network connection interface in the router.
In the implementation, the process of sending the redirect packet to the terminal by the router is the same as the process of step 104, and is not described herein again.
And step 208, the terminal receives the redirection message and accesses the address of the redirection website carried in the redirection message.
In implementation, after receiving the redirection packet sent by the router, the terminal may obtain an address of a redirection website therein, if the address of the redirection website is an IP address, the terminal may establish a TCP connection to a device corresponding to the IP address (the same as the processing in step 203), and then send a web page acquisition request to the router, after receiving the web page acquisition request, the router may search for a network connection interface corresponding to a website carried in the web page acquisition request, and then send the network connection interface to the terminal, the terminal may receive and display the network connection interface, and the user may input an account number and a password to perform a connection operation. If the address of the redirection website is a domain name, the domain name is a domain name of the network connection interface, the terminal may send a DNS query request to the router, where the DNS query request carries the domain name of the network connection interface, and after the router receives the DNS query request sent by the terminal, a thread in which a kernel hook function in the router is located may identify the DNS query request, and if the domain name is a domain name corresponding to the network connection interface, an IP address corresponding to the network connection interface may be fed back to the terminal, and after the terminal receives the IP address sent by the router, a TCP connection may be established with a device corresponding to the IP address (the same as the processing in step 203). And then sending a webpage acquisition request to the router, after receiving the webpage acquisition request, the router can search a network connection interface corresponding to the website carried in the webpage acquisition request, then sending the network connection interface to the terminal, and the terminal can receive and display the network connection interface, so that a user can input an account and a password to perform connection operation.
It should be noted that, since the IP address in step 208 is the network address of the network connection interface, and the network connection interface is stored in the router, the IP address is the IP address of the router, and the corresponding device is the router.
Therefore, under the condition that the router does not have access to the network, the terminal sends the DNS query request, can receive the preset IP address instead of displaying the notification that the webpage acquisition fails, can also establish TCP connection with the router by using the preset IP address, and then the router sends the website of the network connection interface to the terminal. Therefore, the webpage jump is realized on the basis of not changing the http protocol.
As shown in fig. 3, the preset website redirection condition is that the old domain name in the pre-stored correspondence between the new domain name and the old domain name includes the domain name of the website to be accessed, and the execution flow of the embodiment of the present invention may be as follows:
The processing procedure is the same as that of step 101, and is not described herein again.
The processing procedure is the same as that of step 102, and is not described here again.
In implementation, a technician prestores a correspondence between a new domain name and an old domain name in a router, and the new domain name and the corresponding old domain name belong to two domain names of the same website in the correspondence. Or, the router may crawl a new domain name and an old domain name of the website from the network every preset time, for example, the router visits announcements of each website every other week, determines whether to change the domain name, and then adds the new domain name and the old domain name into the corresponding relationship between the new domain name and the old domain name.
After the router receives a DNS query request sent by a terminal, a thread where a kernel hook function is located in the router can identify a domain name of a website to be accessed carried in the router, and if an old domain name in a corresponding relation between a new domain name and an old domain name comprises the domain name of the website to be accessed, the router can acquire a preset IP address and send the preset IP address to the terminal.
In step 304, the terminal receives the preset IP address sent by the router.
The processing is the same as that in step 104, and is not described here again.
In implementation, after receiving a preset IP address sent by a router, a terminal may initiate TCP connection to a device corresponding to the preset IP, specifically, the terminal may send a TCP SYN message to the router, after receiving the TCP SYN message sent by the terminal, the router determines that the IP address is the preset IP address, and may send a TCP SYN + ACK message to the terminal, and after receiving the TCP SYN + ACK message sent by the router, the terminal may send a TCP ACK message to the router, and then sends a web page acquisition request to the router, where the web page acquisition request may be an http service request, where the http service request carries the preset IP address and GET (acquisition) identifier.
In implementation, after the router receives a webpage acquisition request sent by a terminal, a thread where a kernel hook function is located in the router can intercept and identify the webpage acquisition request, if an IP address carried in the webpage acquisition request is a preset IP address, a new domain name corresponding to a domain name of a website to be accessed can be determined in a corresponding relation between the new domain name and an old domain name, and the new domain name is used as an address of a redirection website.
Optionally, the router caches a corresponding relationship between a new domain name and an IP address, and after determining the new domain name corresponding to the domain name of the website to be accessed, the router may determine the IP address corresponding to the new domain name in the corresponding relationship between the new domain name and the IP address, and use the IP address as the address of the redirection website.
Step 307, the router sends a redirection packet to the terminal, where the redirection packet carries an address of the redirection website, so that the terminal accesses the redirection website.
In the implementation, the process of sending the redirect packet to the terminal by the router is the same as the process of step 104, and is not described herein again.
And 308, the terminal receives the redirection message and accesses the address of the redirection website carried in the redirection message.
In implementation, after receiving the redirection packet sent by the router, the terminal may obtain an address of the redirection website therein, and if the address of the redirection website is an IP address, the terminal may establish a TCP connection to the device to which the IP address belongs (the same as the processing in step 203), and then send a web page acquisition request to the router, where the web page acquisition request is carried with the IP address, after receiving the web page acquisition request, the router may forward the web page acquisition request to the device to which the IP address carried in the web page acquisition request belongs, and the device sends a web page corresponding to the IP address to the terminal. If the address of the redirection site is a domain name, the terminal may send a DNS query request to the router, wherein, the domain name is carried, after the router receives the DNS query request, the old domain name in the corresponding relation of the new domain name and the old domain name is determined not to comprise the domain name, the DNS query request may be forwarded to a domain name server, which may query the IP address corresponding to the domain name, then the IP address is sent to the terminal, after the terminal receives the IP address sent by the domain name server, a TCP connection may be established with the device to which the IP address belongs (same process as step 203) and then a web page fetch request is sent to the router, the router can forward the web page acquisition request to the device to which the IP address carried in the web page acquisition request belongs after receiving the web page acquisition request, and the device sends the web page corresponding to the IP address to the terminal.
In the embodiment of the invention, the terminal sends a DNS query request, can receive a preset IP address instead of displaying a notice of webpage acquisition failure, can establish TCP connection with a router by using the preset IP address, then the router sends the website of the redirected website to the terminal, redirects the website to the redirected website under the condition of not changing the execution process of the terminal, and can access the redirected website by the terminal, thereby realizing the redirected website, enabling the domain name displayed in the browser to correspond to the displayed website and not changing the http protocol.
In the embodiment of the invention, a router receives a DNS query request sent by a terminal, if the DNS query request meets a preset website redirection condition, a preset IP address is sent to the terminal, and when a webpage acquisition request sent by the terminal is received, if the IP address carried in the webpage acquisition request is the preset IP address, the address of a pre-stored redirection website is acquired, and a redirection message is sent to the terminal.
