golang封装http get函数请求并且携带header头信息

有遇到这种需求，golang发送GET请求，携带header头信息，比如header里带着验证token

封装函数如下：

//Get请求携带header

func GetWithHeader(url string, headers map[string]string) (string, error) {

client := &http.Client{}

req, err := http.NewRequest("GET", url, nil)

if err != nil {

return "", err

}

for key, header := range headers {

req.Header.Set(key, header)

}

resp, err := client.Do(req)

if err != nil {

return "", err

}

defer resp.Body.Close()

body, err := ioutil.ReadAll(resp.Body)

if err != nil {

return "", err

}

return string(body), nil

}

使用方式如下：

token := "aaaddddffffffffffffsssssssssss"

id := 222

headers := make(map[string]string)

headers["Authorization"] = "bearer " + token

result, _ := tools.GetWithHeader("/url?id="+id, headers)
