According to the domain name redirection method disclosed by the application, when a user accesses a certain website through terminal equipment, if the website is abnormal or a page accessed by the website does not exist, a server of the website returns 404 an error that the page is not found, in order to solve the problem, the abnormal page is prevented from being displayed on a mobile terminal used by the user, and an intelligent gateway connected with the mobile terminal can be set, namely when the server of the website sends a response packet of the website to the intelligent gateway, if a feedback page in the response packet of the website is an abnormal page, the intelligent gateway can directly modify the abnormal page into a preset normal page, such as a Baidu homepage, a Google homepage and the like. The browser started at present by the terminal equipment jumps to a preset normal page, so that the access process of the Internet is more convenient, and the Internet surfing experience of a user is greatly improved.
The following description will explain the technical solutions of the present application by using specific examples. It is to be understood that the application is not limited to those precise embodiments.
Example 1
Referring to fig. 1, an embodiment of the present application provides a domain name redirection method, which can be applied to various intelligent gateways, and can directly modify an abnormal page into a preset normal page, such as a Baidu homepage, a Google homepage, and the like, so as to enable a browser currently started by a terminal device connected to the intelligent gateway to jump to the preset normal page, thereby enabling an access process of the internet to be more convenient and greatly improving a user's internet experience.
As shown in fig. 1, the domain name redirection method is explained in detail below.
Step S100: and acquiring a response packet of the website.
It can be understood that the intelligent gateway is a bridge for the terminal device to communicate with each website, exemplarily, referring to fig. 2, each terminal device of the user, for example, a mobile phone, a computer, a tablet, etc., is connected to the intelligent gateway, the intelligent gateway configures a wireless network name and an encryption manner, and WAN port parameters so as to enable the intelligent gateway to access the internet, the IP address of the terminal device is assigned by the intelligent gateway, for example, the LAN address of the intelligent gateway is 192.168.0.1, the subnet mask is 255.255.255.0, and the address assigned by the terminal device from the intelligent gateway can be 192.168.0.100. The intelligent gateway is connected with the servers of all websites through the Internet, so that all terminal equipment can access all websites through the Internet.
Exemplarily, referring to fig. 3, a communication relationship between a terminal device, an intelligent gateway and a server of a website is shown.
When a user accesses a certain website through a browser of the terminal equipment, the intelligent gateway receives an access request of the terminal equipment, then forwards the access request to a server corresponding to the website, so that the server generates a corresponding response packet according to the access request, and sends the response packet to the intelligent gateway, and the intelligent gateway can acquire the response packet of the website.
Wherein the access request is for accessing a page of the website.
It should be noted that, while the website sends the response packet to the intelligent gateway, other data packets besides the response packet may also be received, for example, some data packets sent by other websites having a cooperative relationship with the website, and at this time, the intelligent gateway needs to intercept the received data packets by using a preset hook point; and determining the response packet from the received data packets according to the identification information of the response packet.
Exemplarily, a hook point can be hung on the Netfilter point of FORWARD of the intelligent gateway to check all packets passing through the hook point.
Step S200: and determining whether a feedback page in the response packet is an abnormal page.
The abnormal page may be determined by the web page status code, for example, if the web page status code of the feedback page is beginning with "4" or beginning with "5", the feedback page may be determined to be the abnormal page.
Illustratively, the web page status code and associated description may be found in the following table.
Figure BDA0003259296370000071
Figure BDA0003259296370000081
The abnormal page may also be determined by the web page content, for example, if the web page content includes predetermined characters such as "page not found", "request timeout", "request failure", and the like, the feedback page is an abnormal page.
It can be understood that the abnormal page can also be determined by the web page content and the web page status code, that is, the web page content and the web page status code are comprehensively judged to determine whether the feedback page is the abnormal page.
Exemplarily, referring to fig. 4, the process of determining the abnormal page may include the following steps:
step S210: and determining whether the webpage state code in the response packet belongs to the number in the number set.
It will be appreciated that the number set may include web page status codes beginning with "4" and beginning with "5". Comparing the webpage state code in the response packet with each state in the number set, if the webpage state code belongs to the number in the number set, executing the step S220, and if the webpage state code does not belong to the number in the number set, executing the step S230.
Step S220: and determining that a feedback page in the response packet is an abnormal page.
Step S230: and determining that the feedback page in the response packet is a normal page.
Exemplarily, referring to fig. 5, the process of determining the abnormal page may further include the following steps:
step S240: determining whether the web page content in the response packet includes a predetermined character.
The predetermined characters include, but are not limited to, "page not found", "request timeout", and "request failure". If the predetermined character is included, step S220 is executed, and if the predetermined character is not included, step S230 is executed.
It should be noted that the determining process of the abnormal page may only include step S210 to step S230, or may only include step S240 to step S260, and of course, the step S210 and the step S240 may also be executed partially in sequence to determine whether the feedback page is the abnormal page, and the accuracy of determining the abnormal page may be ensured through the double determination of the step S210 and the step S240.
Step S300: and if the page is abnormal, modifying the content in the response packet into preset content and then forwarding the content to the terminal equipment, wherein the preset content is used for enabling a browser currently started by the terminal equipment to jump to a preset page.
Exemplarily, the modifying the content in the response packet into the preset content includes: the webpage state code in the response packet is modified into a preset number, for example, the original network state code '404' in the response packet is modified into '302', so that the requested page is temporarily jumped to a preset page through the network state code '302', and further, under the condition that the requested website is abnormal or the website page is lost, the browser of the mobile terminal can be prevented from displaying an abnormal page, a user does not need to manually restore the search page returned by the browser page again, the search time of the user is saved, the access process of the internet is enabled to be more convenient, and the internet surfing experience of the user is greatly improved.
The value is that the setting authority and the modification authority of the predetermined page can be opened to the user, and the user is allowed to modify the predetermined page at any time according to personal preference.
