How to Solve \'Proxy Authentication Required\' Errors in Go HTTP Requests?

Proxy Authentication with HTTP Requests in Go

When using an authenticated proxy IP address for HTTP requests, you may encounter the "Proxy Authentication Required" error. To resolve this issue, you need to provide the username and password for the proxy server.

Setting Up Proxy Authentication

In the HTTP transport used for your requests, set up the HEADER as follows:

<code class="go">auth := "username:password"
basicAuth := "Basic " + base64.StdEncoding.EncodeToString([]byte(auth))
transport.ProxyConnectHeader = http.Header{}
transport.ProxyConnectHeader.Add("Proxy-Authorization", basicAuth)</code>

By setting the "Proxy-Authorization" header with the provided username and password, the HTTP client will be able to authenticate with the proxy server. This will allow you to bypass the "Proxy Authentication Required" error and successfully access the desired webpages.
