一、参考
1、Get请求封装
func Get(url string, params map[string]string, headers map[string]string) (*http.Response, error) {
req, err := http.NewRequest("GET", url, nil)
if err != nil {
log.Println(err)
return nil, errors.New("new request is fail ")
}
q := req.URL.Query()
if params != nil {
for key, val := range params {
q.Add(key, val)
}
req.URL.RawQuery = q.Encode()
}
if headers != nil {
for key, val := range headers {
req.Header.Add(key, val)
}
}
client := &http.Client{
}
log.Printf("Go GET URL : %s \n", req.URL.String())
return client.Do(req)
}
2、Post请求封装
func Post(url string, body map[string]string, params map[string]string, headers map[string]string) (*http.Response, error) {
var bodyJson []byte
var req *http.Request
if body != nil {
var err error
bodyJson, err = json.Marshal(body)
if err != nil {
log.Println(err)
return nil, errors.New("http post body to json failed")
}
}
req, err := http.NewRequest("POST", url, bytes.NewBuffer(bodyJson))
if err != nil {
log.Println(err)
return nil, errors.New("new request is fail: %v \n")
}
req.Header.Set("Content-type", "application/json")
q := req.URL.Query()
if params != nil {
for key, val := range params {
q.Add(key, val)
}
req.URL.RawQuery = q.Encode()
}
if headers != nil {
for key, val := range headers {
req.Header.Add(key, val)
}
}
client := &http.Client{
}
log.Printf("Go POST URL : %s \n", req.URL.String())
return client.Do(req)
}
二、按需调整
- 我不需要所有的
response 内容，我只要返回的 res.Body 数据
1、GET请求
func Get(url string, params map[string]string, headers map[string]string) ([]byte, error) {
req, err := http.NewRequest("GET", url, nil)
if err != nil {
log.Println(err)
return nil, errors.New("new request is fail ")
}
q := req.URL.Query()
if params != nil {
for key, val := range params {
q.Add(key, val)
}
req.URL.RawQuery = q.Encode()
}
if headers != nil {
for key, val := range headers {
req.Header.Add(key, val)
}
}
client := &http.Client{
}
log.Printf("Go GET URL : %s \n", req.URL.String())
res, err := client.Do(req)
if err != nil {
return nil, err
}
defer res.Body.Close()
resBody, err := ioutil.ReadAll(res.Body)
if err != nil {
return nil, err
}
return resBody, nil
}
2、POST请求
func Post(url string, body map[string]interface{
}, params map[string]string, headers map[string]string) ([]byte, error) {
var bodyJson []byte
var req *http.Request
if body != nil {
var err error
bodyJson, err = json.Marshal(body)
if err != nil {
log.Println(err)
return nil, errors.New("http post body to json failed")
}
}
req, err := http.NewRequest("POST", url, bytes.NewBuffer(bodyJson))
if err != nil {
log.Println(err)
return nil, errors.New("new request is fail: %v \n")
}
req.Header.Set("Content-type", "application/json")
q := req.URL.Query()
if params != nil {
for key, val := range params {
q.Add(key, val)
}
req.URL.RawQuery = q.Encode()
}
if headers != nil {
for key, val := range headers {
req.Header.Add(key, val)
}
}
client := &http.Client{
}
log.Printf("Go POST URL : %s \n", req.URL.String())
res, err := client.Do(req)
if err != nil {
return nil, err
}
defer res.Body.Close()
resBody, err := ioutil.ReadAll(res.Body)
if err != nil {
return nil, err
}
return resBody, nil
}
三、其他
因为还在学习之中，如果内容有误，请宽容指出，不胜感激~
四、json.Marshal()方法 特殊字符&被转义
- 如果希望
json.Marshal() 特殊字符&不被转义为\u0026：请参考 golang 微信小程序获取二维码scene参数报错 invalid scene rid: f05f96ab-5382f139-14b13d2f
