Usually how to tech is
` req, err := http.NewRequest("GET", "http://example.com", nil) req.Header.Add("Authorize", "dswxswsxw") resp, err := client.Do(req) ` BUT Have problem inside. So…. use this
` headers := http.Header{ "Accept-Encoding": []string{"gzip, deflate"}, } req, err := http.NewRequest("GET", url, nil) req.Header = headers client := &http.Client{} resp, err = client.Do(req) ` More Safe.
