How to Use a Proxy for HTTP Requests in Go

Use the http.ProxyFromEnvironment function to automatically configure your http.Client to respect HTTP_PROXY, HTTPS_PROXY, and NO_PROXY environment variables.

package main

import (
	"net/http"
)

func main() {
	client := &http.Client{
		Transport: &http.Transport{
			Proxy: http.ProxyFromEnvironment,
		},
	}
	// Use client.Get("https://example.com") instead of http.Get
}

Using a proxy for HTTP requests in Go tells your program to check system environment settings before making web requests. If you have a proxy server configured in your terminal or OS, the program will automatically route traffic through it. It works like a browser that respects your network settings without needing extra code.
