Embodiment 1
[0028] figure 1 It is an implementation flowchart of the page redirection method provided by the embodiment of the present invention, and is described in detail as follows:
[0029] In step S101, at the entrance of the communication tunnel of the control and configuration protocol CAPWAP of the wireless access point, the data message sent by the client is received;
[0030] Among them, the data message is received through the UDP 5247CAPWAP communication tunnel, and the obtained user data message is a complete one.
[0031] In step S102, when the data message is a TCP connection message, analyze the data message and record the destination IP and port;
[0032] In step S103, check the current state of the client, if the current state is a state to be authenticated, then intercept the TCP SYNC message of the client;
[0033] Wherein, the SYNC message of TCP 80 will be intercepted and the real destination IP and port of the server requested by the user will be recorded when the...

[0046] figure 2 It is the first implementation flowchart of step S105 in the page redirection method provided by the embodiment of the present invention, and is described in detail as follows:
[0047] In step S201, detecting that the request mode carried by the HTTP data request message is a GET request mode;
[0048] In step S202, a 302 response mode corresponding to the GET request mode is selected.
[0049]Wherein, the 302 response mode corresponding to the GET request mode is selected to facilitate subsequent loading of the Portal page address.
Embodiment 3
[0051] image 3 It is the second implementation flowchart of step S105 in the page redirection method provided by the embodiment of the present invention, and is described in detail as follows:
[0052] In step S301, the method of detecting that the request carried in the HTTP data request message is a POST request method;
[0053] In step S302, a 303 response mode corresponding to the POST request mode is selected.
[0054] Wherein, the 303 response mode corresponding to the POST request mode is selected to facilitate subsequent loading of the Portal page address.

Abstract
The present invention is applicable to the communication field, and provides a page redirection method and device, the method comprising: at the entrance of the communication tunnel of the control and configuration protocol CAPWAP of the wireless access point, receiving the data message sent by the client; parsing the data message And record the destination IP and port; intercept the client's TCP SYNC message; according to the client's TCP SYNC message, target IP and port, encapsulate it into an access reply message, seal the CAPWAP header, and communicate the access reply message through CAPWAP The tunnel returns to the client; receive and intercept the HTTP data request message sent by the client, detect the request method carried in the HTTP data request message, and select the response method corresponding to the request method; according to the response method, encapsulate the custom The address of the Portal page to which the page is redirected is returned to the client through the CAPWAP communication tunnel after the CAPWP header is sealed. The beneficial effect of the invention lies in two aspects. On the one hand, the processing efficiency of page redirection is improved, and on the other hand, it is beneficial to transplantation and popularization.
Description
technical field [0001] The invention belongs to the communication field, and in particular relates to a page redirection method and device. Background technique [0002] With the widespread deployment of wireless local area networks in parks, public places, universities, enterprises, hospitals, hotels, restaurants and other environments, the authentication management of end users is extremely important. Among them, web authentication is the simplest authentication method. It does not require users to install special application software in the client. During the web authentication process, the current page is redirected to the Portal page set by the WIFI hotspot through the page redirection method. , to complete the authentication. [0003] However, the existing page redirection method has large system overhead and long processing time, which reduces the processing efficiency of page redirection and is not conducive to popularization and use. The reason is that in the exis...
