How to upload a file and some data through HTTP multipart in Python 3 using the requests library

Undeniably, the HTTP protocol had become the dominant communication protocol between computers.

Through the HTTP protocol, a HTTP client can send data to a HTTP server. For example, a client can upload a file and some data from to a HTTP server through a HTTP multipart request.

If you are building that client with Python 3, then you can use the requests library to construct the HTTP multipart request easily.

In case you need it, this is how we can upload a file and some data through HTTP multipart in Python 3 using the requests library.

How to upload a file via a HTTP multipart request in Java without using any external libraries

There was this situation when there was a need for my applet to send some log files (generated by some desktop application) on the remote clients.

To keep my applet lean, I chose to implement this file upload function by sending a HTTP multipart request when my applet loads on the remote client’s browser. Policies were in place to ensure that my applet was able to read the log files and send them back to a web server which will collect the log files.

This post documents how I can upload a file by sending a HTTP multipart request in Java without using any external libraries. For the sake of brevity, I used the server endpoint that I had discussed earlier to accept the file from the codes that will be mentioned in this post.
