Problems solved by technology

With the application of four-layer switching technology, in order to realize file upload and download based on four-layer switching technology, the same file must be saved in each web server, because the web server that the operator interacts with each time may not be For the same server, if you want to ensure that the operator can successfully download the file every time, you need to save the same file on each WEB server when uploading the file, which will lead to repeated storage of attachments, wasting storage space and other defects

Embodiment Construction

[0044] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0045] As a first aspect of the present invention, a file access system is provided, such as figure 1 As shown, the system includes at least one client 100, at least one WEB server 200, a file library server 300, and a relational database 400, and the WEB server 200 communicates with the client 100, the relational database 400, and the file library server 300 respectively. Wherein, the client 100 sends the file to be uploaded (ie, the file to be uploaded to the file library server 300 ) to the file library server 300 through the WEB server 200 for storage, and receives the file downloaded from the file library server 300 by the WEB server 200 . WEB server 200 also controls to generate the stored filename of the file...

Abstract

The invention provides a file access system, which comprises at least one client, at least one WEB server, a file library server and a relation database, wherein the WEB server communicates with the client, the relation database and the file library server respectively; the client sends a file to be uploaded to the file library server through the WEB server for storage and receives a file downloaded by the WEB server from the file library server; and the WEB server also controls to generate a stored file name of the file to be uploaded and sends the generated stored file name and a real file name of the file to be uploaded to the relation database for storage. Furthermore, the invention also provides a file uploading method and a file downloading method which are implemented by using the file access system. By the technical scheme, the file can be uploaded and downloaded conveniently and the same files are not required to be stored repeatedly, so that storage resource waste caused by repeated storage can be avoided and a requirement on the storage capacity of the server is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a system and method for file upload and file download. Background technique [0002] At present, in order to realize the function of uploading and downloading files, it is generally required that each interaction is completed on the same host, that is, the uploading and downloading of files are performed on the same web server. With the application of four-layer switching technology, in order to realize file upload and download based on four-layer switching technology, the same file must be saved in each web server, because the web server that the operator interacts with each time may not be On the same server, if you want to ensure that the operator can successfully download the file every time, you need to save the same file on each WEB server when uploading the file, which will lead to repeated storage of attachments, wasting storage space and other defects. [0003] Servlet is a se...
