Abstract

The embodiment of the invention discloses a file uploading and downloading method and system, and the method comprises the steps: responding to a file uploading instruction initiated by a user in an interface through a client API, popping up a file selection box through a browser, and enabling the user to select files with specified file types and quantity in configuration information for uploading; the client API carries out file slicing on files meeting the specified file type and quantity one by one according to the configuration information, the files are sent one by one after being sliced, a file MD5 code, an uploading identification instruction and user information are attached to the files, and the files are sent to the file server side; after all the file slices are uploaded, the client API sends a file slice merging instruction, a file MD5 code and an uploading identification instruction to the file server; and the file server side receives the uploading identification instruction, performs verification processing according to the configuration information, stores the slice data and the user information according to the MD5 code of the file, and completes slice merging into file storage and clears the slice data when receiving a file slice merging instruction of the client side.

Description

technical field [0001] The present invention relates to the technical field of file storage, and more specifically, to a method and system for uploading and downloading files. Background technique [0002] File transfer is an integral part of the information system. The speed of file transfer affects the user's experience. Files containing malicious code will cause damage and loss to the system and even the user's interests. However, the existing method for uploading and downloading files has problems such as low transmission efficiency, inability to guarantee file consistency, and low system security. Contents of the invention [0003] In order to solve the above-mentioned technical problems such as low transmission efficiency, inability to guarantee file consistency and low system security in the existing file uploading and downloading method, the present invention is proposed. Embodiments of the present invention provide a method and system for uploading and downloadin...
