File access method, system and equipment

Abstract

The invention discloses a file access method, a file access system and equipment, wherein the equipment comprises a downloading server. The downloading server comprises a file storage, a downloading request processor, a log storage and a log processor; the file storage is configured for storing local files; the downloading request processor is configured for receiving a file downloading request sent by a client; a file corresponding to the file downloading request is looked for in the file storage, and the found file is returned to the client; the log storage is configured for storing a log which records the processing of the file downloading request through the downloading request processor; the log processor is configured for extracting a file missing log record which indicates that the requested file is not stored in the file storage from the log storage; and according to the extracted file missing log record, the missed file of the downloading server is determined, and is downloaded to the file storage. With the adoption of the file access method, the file access system and the equipment, timeliness of fault handling of an access failure method and user access experience can be improved.

Description

technical field [0001] The invention relates to the field of Internet applications, in particular to a download server, a log processor, a file access method and system, and a method for processing file download requests at the server. Background technique [0002] During the distribution process of CDN (Content Delivery Network, Content Delivery Network), due to various reasons, some files may be missing on the download server (DLServer). When a user accesses a download link, if the download link happens to correspond to a missing file, the user will be prompted that the access failed, for example (http status code 404, indicating that the access failed), which affects the user experience. [0003] At present, most websites handle access failures (such as 404 status codes) mainly by setting redirection pages. Redirects a 404 status code to a status page indicating that the file cannot be accessed. When it is found that a download server outputs a large number of 404 statu...

AI Technical Summary

Problems solved by technology

When a download server is found to output a large number of 404 status codes, the download server may be missing a large number of files, which will cause the download server to go offline

[0004] It can be seen from this that the current method for handling access failures is poor in timeliness, and a certain download server will be taken offline only when it is confirmed that a large number of files are missing

Before the download server goes offline, there are still a large number of users accessing it, and a large number of access failures will cause waste of network resources and poor user access experience
