How to use proxies with authentication in my HTTP requests?

Question

I have a proxy IP Address (that also require a username and password). When i try using them to visit webpages, i get "Proxy Authentication Required".

I'm found this other Stackoverflow post from 2016, and this Github Issue that was closed, but they don't provide anything useful:

Any suggestions?

EDIT: Saw this post: Setting up proxy for HTTP client

It's kinda close. However, for some urls I'm able to get a successful response using my proxy, but for certain urls, I get a "Proxy Authorization Required".

If you're following this authorized proxy tutorial, the additional step you would have to do is to set up the HEADER in the transport.

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

If there are other headers required by the request, such as Content-Type or Accept, you should also add them to the ProxyConnectHeader. – Juan Nov 21 '18 at 19:07

to add authorization, you may need to add a header:

auth := "{user}:{password}"
basicAuth := "Basic " + base64.StdEncoding.EncodeToString([]byte(auth))
request.Header.Add("Proxy-Authorization", basicAuth)
