Tracking Progress of HTTP POST Requests in Go

When sending large files and images via POST requests, developers often face challenges in tracking upload progress. This question explores a reliable method to monitor the progress of such requests in a Go application.

The question suggests manually opening a TCP connection and sending HTTP requests in chunks. However, this approach may encounter limitations with HTTPS sites and is not considered optimal.

The response suggests an alternative solution using a custom io.Reader implementation. By wrapping the actual reader, you can output progress information each time Read is called. The provided example code illustrates how to create a ProgressReader that updates the user as data is sent.

This solution provides a simple and effective way to track the progress of HTTP POST requests in Go, allowing developers to monitor the upload status of large files without relying on manual TCP connections.
