Problems solved by technology

[0003] When the resource information is distributed to the user terminal through the CDN, if the cached file on the CDN is incomplete or the content is wrong, the user terminal will download an invalid file, which will cause very serious business problems and reduce the security of the CDN resource.

Embodiment approach

[0054] An implementation manner of obtaining resource verification information in the embodiment of the present invention includes:

[0055] Responding to sending the received resource acquisition request to the target node, receiving hypertext transfer protocol information fed back by the target node;

[0056] Analyzing the hypertext transfer protocol information to obtain verification information in the hypertext transfer protocol header.

[0057]In this implementation manner, the verification information is obtained through the Http header, for example, three additional pieces of information CK-Digest, IF-Match-CK, and CK-Digest-Method are added to the Http header. Correspondingly, CK-Digest represents the verification value of the file included in the returned header; CK-Digest-Method represents the verification algorithm of the file included in the returned header (MD5, SHA1, SHA256 or other verifications agreed upon by both parties) algorithm); IF-Match-CK represents th...

Abstract

The invention discloses a resource verification method and device for a content distribution network, and the method comprises the steps: obtaining the verification information of a resource in response to a received resource obtaining request; verifying the resource based on the verification information, and if the verification is passed, distributing the resource to a request end corresponding to the resource acquisition request; and if the verification is not passed, generating feedback information of request failure, and sending the feedback information to the request end. According to the invention, after the resource request is obtained, the resource can be verified, the verified resource is distributed, the security of the resource is ensured, and the normal operation of the service is further ensured.

Description

technical field [0001] The present invention relates to the field of content distribution network, in particular to a resource verification method and device for content distribution network. Background technique [0002] CDN (Content Delivery Network, Content Delivery Network) is a distributed caching system whose main function is to cache the content of the original website to a location closer to the user's geographical location for acceleration. The content cached by the CDN node is obtained from the origin site, so the CDN node needs to initiate a request to the origin site and distribute it to the corresponding user terminal after obtaining the response cache content. [0003] When the resource information is distributed to the user terminal through the CDN, if the cached file on the CDN is incomplete or the content is wrong, the user terminal will download an invalid file, which will cause very serious business problems and reduce the security of the CDN resource. . ...
