Check information acquisition methods and devices, resource information checking methods and devices, resource publishing methods and devices, and electronic equipment

Abstract

The embodiment of invention provides resource check information acquisition methods and devices, resource information checking methods and devices, resource publishing methods and devices, and electronic equipment. One resource checking method comprises the following steps: receiving a resource download request sent by a request node, comparing first interval information in the request with interval range of each block resource contained in a to-be-downloaded resource searched in a local storage unit, and determining a first block source with overlapping interval with the first interval information; performing checking computation on each first block source by adopting a preset checking algorithm to obtain a third checking value; comparing each third checking value with the checking valuecorresponding to the same block source in the block checking information stored in a local information base; if each third checking value is same as the checking value corresponding to the same blocksource, sending a resource part corresponding to the first interval information in the corresponding block resource to a request node. Through the scheme provided by the embodiment of the invention, the block checking can be performed on the shared resource in the P2P network, thereby improving a sharing rate of a resource file.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device, and electronic device for acquiring verification information, verifying resources, and publishing. Background technique [0002] The peer-to-peer computer network (Peer to Peer, P2P) system is composed of many P2P nodes, each node can download resources through the P2P network, after downloading the complete resources, the resources can also be released to the resource server, and uploaded to other nodes. Serve. [0003] In the P2P network system, due to various problems such as hijacking and tampering of network data, redirection of small operators, and local data destruction caused by bad disk cards, error data will appear during data transmission. If there is wrong data in the video resource, it will cause the user to experience various playback abnormalities such as freezes and blurred screens during video playback, which greatly affects the...

Problems solved by technology

[0007] However, in the existing solutions, once erroneous data appears, the entire resource needs to be deleted

For large resource files (for example: video, generally ranging from a few MB to several GB), the deletion of the entire file due to partial wrong data, and then re-downloading will cause a huge waste of resources

[0008] In addition, existing solutions cannot solve the situation where local data is destroyed

For example, after the download is completed, the MD5 verification is used to pass, but the file data is destroyed during the local storage process. When uploading resources, directly providing data to the other party will still introduce wrong data to the network.
