Abstract

The invention discloses a file downloading method and system. The file downloading method comprises the steps that a user file downloading page is returned through the HTTPS, wherein the file downloading page comprises a temporary download link of a file, a download agency and a TOKEN, and the download agency is used for intercepting and capturing a temporary download link request which is sent by a user and encrypting a time stamp and a URL parameter in the temporary download link based on the TOKEN so that a validation value can be obtained and added to a URL request to obtain the actual download link of the file; the TOKEN and a comparison time stamp are obtained through the file identification in the URL request parameter and the time stamp, and a validation value is generated based on encryption of the TOKEN and is compared with the validation value in the URL request to finally generate a comparison result; a specific file downloading service is provided according to the comparison result. The file downloading system comprises a download agency generation module, a download validation service module and a download data service module. The file downloading method and system have the advantages that the download link of the file can be prevented form being divulged and downloading of legitimate users is guaranteed.
