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

Example Embodiment

[0155] Example one

[0156] based on figure 2 The logical idea of ​​the resource sharing scheme shown, such as image 3 As shown, it is the flow of the method for acquiring resource verification information shown in the embodiment of the present invention Figure one , The main execution of this method is figure 2 The requesting node among the P2P nodes shown in. Such as image 3 As shown, the method for obtaining resource verification information includes the following steps:

[0157] S310: Send a resource information request to the server to obtain resource information of the resource to be downloaded;

[0158] For example, when the user clicks to play a video file (resource to be downloaded) on the client App, the client App will send a file playback request to the accelerator. The form of the playback request can be a Hyper Text Transfer Protocol (HTTP) request. Such as http: / / 127.0.0.1:7878 / www.youku.com / xxxxxx.flv. In the HTTP header, the interval information corresponding ...

[0173] based on figure 2 The logical idea of ​​the resource sharing scheme shown, such as Figure 4 As shown, it is the flow of the method for acquiring resource verification information shown in the embodiment of the present invention Figure II , The main execution of this method is figure 2 The requesting node among the P2P nodes shown in. Such as Figure 4 As shown, the method for obtaining resource verification information includes the following steps:

[0174] S410. Send a resource information request to the server to obtain resource information of the resource to be downloaded. The resource information includes: the first check value of the block check information and resource node information; the block check information is used for the number of resources to be downloaded. The first check value is used to check the block check information, and the resource node information indicates that the resource information request of the node where the resource...

[0197] Example three

[0198] based on figure 2 The logical idea of ​​the resource sharing scheme shown, such as Figure 5 As shown, it is the flow of the method for verifying block resources shown in the embodiment of the present invention Figure one , The main execution of this method is figure 2 The resource node among the P2P nodes shown in. Such as Figure 5 As shown, the method for verifying block resources includes the following steps:

[0199] S510: Receive a resource download request sent by the requesting node, where the resource download request includes first section information of the resource to be downloaded;

[0200] Wherein, the first interval information is the range information corresponding to the entire resource to be downloaded for part of the resources to be downloaded each time requested by the requesting node.

[0201] The requesting node divides all the requested resources into multiple P2P tasks, and then starts a request for downloading resources to the ...

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...
