)
func HTTPRequestCustomUserAgent(url, userAgent string) (b []byte, err error) {
req, err := http.NewRequest("GET", url, nil)
if err != nil {
return
}
req.Header.Set("User-Agent", userAgent)
client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
return
}
defer resp.Body.Close()
if resp.StatusCode != 200 {
err = errors.New(
"resp.StatusCode: " +
strconv.Itoa(resp.StatusCode))
return
}
return ioutil.ReadAll(resp.Body)
}
func main() {
b, err := HTTPRequestCustomUserAgent("https://www.google.com/", "My User-Agent")
