Abstract

Disclosed are a method and device for processing continuous redirection. The method comprises: when a service request that redirection processing needs to be performed is received, the number of redirections corresponding to the service request is determined and it is judged whether the number of redirections reaches a pre-set threshold value; if so, the redirection of the service request is interrupted, and after the redirection of the service request is interrupted, the service request is resumed redirecting to a destination address; and if not, the service request is redirected to the destination address. In the embodiments of the present application, a redirection processing device can avoid error processing (e.g. 404 error) induced by the case where the number of 302 redirections exceeds the number of times restricted by a browser and thus avoid service interruption and service failure, thereby improving the service experience and the user experience.

Claims

1. A method for processing continuous redirection, comprising:

when a service request that redirection processing needs to be performed is received, determining the number of redirections corresponding to the service request, and judging whether the number of redirections reaches a pre-set threshold value;

if so, interrupting the redirection of the service request, and after the redirection of the service request is interrupted, resuming the redirection of the service request to a destination address; and

if not, redirecting the service request to the destination address.

2. The method according to claim 1, wherein

the process of interrupting the redirection of the service request, and after the redirection of the service request is interrupted, resuming the redirection of the service request to a destination address comprises:

temporarily inserting an intermediate page, to interrupt continuous redirection corresponding to the service request by inserting the intermediate page; and

after the redirection of the service request is interrupted by inserting the intermediate page, resuming the redirection of the service request to the destination address.

3. The method according to claim 2, wherein

the head of a Hyper Text Markup Language (HTML) of the intermediate page comprises a pre-set instruction for resuming the redirection of the service request to the destination address after the intermediate page is inserted.

4. The method according to claim 1, wherein

the process of interrupting the redirection of the service request, and after the redirection of the service request is interrupted, resuming the redirection of the service request to a destination address comprises:

calling an interruption manner configured in a continuous 302 redirection method pool, and interrupting continuous redirection corresponding to the service request in the interruption manner; and

after the redirection of the service request is interrupted in the interruption manner, resuming the redirection of the service request to the destination address;

wherein an interruption manner for interrupting the redirection of the service request is configured in the continuous 302 redirection method pool.

5. The method according to claim 1, wherein the method further comprises:

storing, in a memory, a correspondence relationship between a service ID corresponding to the service request and the number of redirections;

wherein an initial value of the number of redirections is 0;

each time the service request is redirected to the destination address, determining the service ID corresponding to the service request, and adding 1 to the number of redirections corresponding to the service ID in the memory; and

when the redirection of the service request is interrupted, determining the service ID corresponding to the service request, and resetting the number of redirections corresponding to the service ID in the memory.

6. The method according to claim 5, wherein the method further comprises:

when the number of redirections does not reach the pre-set threshold value, if error processing induced by the case where the number of redirections exceeds the pre-set threshold value occurs in the service request, determining the service ID corresponding to the service request, and querying for the number of redirections corresponding to the service ID in the memory; and

adjusting the pre-set threshold value to the number of redirections corresponding to the service ID, and resetting the number of redirections corresponding to the service ID in the memory.

7. The method according to claim 1, wherein, before a service request that redirection processing needs to be performed is received, the method further comprises:

intercepting all service requests in the process of redirecting a service request to a destination address, to select, from all the service requests, a service request that redirection processing needs to be performed.

8. The method according to claim 1, wherein

the redirection comprises a 302 redirection.

9. A redirection processing device, comprising:

a determination module, configured to, when a service request that redirection processing needs to be performed is received, determine the number of redirections corresponding to the service request;

a judgment module, configured to judge whether the number of redirections reaches a pre-set threshold value; and

a processing module, configured to, if the number of redirections reaches the pre-set threshold value, interrupt the redirection of the service request, and after the redirection of the service request is interrupted, resume redirecting the service request to a destination address; and

if the number of redirections does not reach the pre-set threshold value, redirect the service request to the destination address.

10. The redirection processing device according to claim 9, wherein

the processing module is configured to temporarily insert an intermediate page, to interrupt continuous redirection corresponding to the service request by inserting the intermediate page;

and after the redirection of the service request is interrupted by inserting the intermediate page, resume redirecting the service request to the destination address.

11. The redirection processing device according to claim 10, wherein the head of a Hyper Text Markup Language (HTML) of the intermediate page comprises a pre-set instruction for resuming the redirection of the service request to the destination address after the intermediate page is inserted.

12. The redirection processing device according to claim 9, wherein

the processing module is configured to call an interruption manner configured in a continuous 302 redirection method pool, and interrupt continuous redirection corresponding to the service request in the interruption manner;

and after the redirection of the service request is interrupted in the interruption manner, resume redirecting the service request to the destination address;

wherein an interruption manner for interrupting the redirection of the service request is configured in the continuous 302 redirection method pool.
