Description

Remote file access method, server, client and system

technical field

The invention relates to the field of computer technology, in particular to a remote file access method, server, client and system.

Background technique

With the rapid development of Internet technology, people can store some of their own resources through the server, reduce the pressure on client storage, and can access through different clients, greatly reducing the space restrictions when accessing resources, making access to resources more convenient.

For example, after a user logs in to client A, he uploads the edited file to the server through client A, and then the user wants to access the file just uploaded to the server in client B, then the user can log in to the client Client B obtains the corresponding file in the server through Client B to access it.

It can be seen that if the user wants to access the files in the server, he must first log in to the client. There are generally two ways to log in, one is to log in by manually entering an account number and password, and the other is to log in through a specific physical device such as a U disk lock. The principle of the U disk lock is to pre-write the account number and password in the U disk lock, and after inserting the U disk lock, the account number and password will be read from it instead of manual input.

However, the process of manually entering the account number and password to log in is cumbersome, and the user needs to enter the account number and password at the same time, which is easy to make mistakes; physical devices such as U disk locks have the problem that they are easy to forget to carry. Therefore, no matter which way it is, it is very inconvenient and inefficient when it is necessary to access files on the server.
