What Happened on Tcp When Uploading a File
I'm looking to find some assistance in my python socket programming.
Objective: upload a file from the Client to the Server. My current setup involves two virtual machines, a Server and a Client, where the respective .py files will reside; server.py and customer.py . The issues I'yard experiencing is, that when I go to cull the upload option, the output reads "File uploading.... File successfully uploaded" Only when I expect on the server side, the file doesn't exist - nor do I receive an error. The server shows that information technology received a connectedness when I ship the file to upload. What I have currently is beneath... Any assist would exist profoundly appreciated.

Your uploadFile() method will connect() to the server so sendall() the file content (in 1024 byte chunks).
Your server, on the other hand, will receive the first 1024 bytes (i.e. the first 1024 bytes of file content), and translate it according to the protocol, looking at the showtime three bytes of the file content. The customer, however, never sends protocol.HEAD_UPLOAD as the server expects.
(BTW, I would really recommend y'all PEP8 the code, and refrain from * imports. It makes the code much easier to read, and thus to aid.)

Your uploadFile() method will connect() to the server and and so sendall() the file content (in 1024 byte chunks).
Your server, on the other manus, will receive the beginning 1024 bytes (i.e. the outset 1024 bytes of file content), and interpret it according to the protocol, looking at the first three bytes of the file content. The client, however, never sends protocol.HEAD_UPLOAD as the server expects.
(BTW, I would really recommend you PEP8 the code, and refrain from * imports. Information technology makes the code much easier to read, and thus to help.)
