Basic HTTP Auth in Go

go basic-authentication

the potential 'gotcha' is if your website does any redirects... Go-lang will drop your specified headers on the redirects. (I had to do wireshark to see this! You can quicky find out in chrome by right-clicking then "inspect element" and click network tab)

you'll want to define a redirect function that adds the header back in.

func basicAuth(username, password string) string {
  auth := username + ":" + password
  return base64.StdEncoding.EncodeToString([]byte(auth))
}

func redirectPolicyFunc(req *http.Request, via []*http.Request) error{
  req.Header.Add("Authorization","Basic " + basicAuth("username1","password123"))
  return nil
}

func main() {
  client := &http.Client{
    Jar: cookieJar,
    CheckRedirect: redirectPolicyFunc,
  }

  req, err := http.NewRequest("GET", "http://localhost/", nil)
  req.Header.Add("Authorization","Basic " + basicAuth("username1","password123")) 
  resp, err := client.Do(req)
}

You need to specify the protocol for NewRequest, e.g. "http://", see here.

req, err := http.NewRequest("GET", "http://mydomain.com", nil)
