PYTHON-FTP Program

First, requirements:

User encryption authentication
Allow simultaneous multi-user logins
Each user has their own home directory and can only access their home directory
Disk quotas for users, with different free space per user
Allow user to switch directories at random on FTP server
Allow users to view files in the current directory
Allows uploading and downloading of files to ensure file consistency
Show progress bar during file transfer
Additional features: Support for file breakpoint continuation (download only)

Second, the directory structure:

.

││
│ ├──bin # Executable Program Entry directory
│ │  ├──__init__.py
│ │   └──start.py # main logic file + boot portal
│├──conf # profile directory

Third, process, program (see annex)

Iv. operational matters of the program
1, run server.py and then run start.py
2. Admin: admin 123 {"name": "admin", "password": "202cb962ac59075b964b07152d234b70"}
3. User Wenjie 123 {"username": "Wenjie", "Password": "202cb962ac59075b964b07152d234b70", "Size": "10M"}
Alex 123 {"username": "Alex", "Password": "202cb962ac59075b964b07152d234b70", "Size": "10M"}
4. Command Help:

LS--Print the current directory (LS after the parameter, directly print the current directory file)
CD--Switch directory (CD must be followed directory parameter: XXX user \xxx file)
mkdir--Create folder (mkdir directory name)
Get--Download (Get access to target file directory: Server_data\ file)
Put--Upload (Put file-server_data\ directory)
Quit--Return to superiors



V. Summary

1, most of the basic implementation of the function, multi-user concurrency, the continuation of the breakpoint is not implemented
2, the completion of the job did not meet expectations, left a lot of problems, the actual development process is still very slow, a lot of knowledge points in the use of unskilled

Six, the Code
