go对get post请求封装

一、参考1、Get请求封装2、Post请求封装二、按需调整1、GET请求2、POST请求三、其他四、json.Marshal()方法特殊字符&被转义

一、参考

参考地址：go对get、post请求封装

1、Get请求封装

//Get http get methodfunc Get(url string, params map[string]string, headers map[string]string) (*http.Response, error) {//new requestreq, err := http.NewRequest("GET", url, nil)if err != nil {log.Println(err)return nil, errors.New("new request is fail ")}//add paramsq := req.URL.Query()if params != nil {for key, val := range params {q.Add(key, val)}req.URL.RawQuery = q.Encode()}//add headersif headers != nil {for key, val := range headers {req.Header.Add(key, val)}}//http clientclient := &http.Client{}log.Printf("Go GET URL : %s \n", req.URL.String())return client.Do(req)}

2、Post请求封装

//Post http post methodfunc Post(url string, body map[string]string, params map[string]string, headers map[string]string) (*http.Response, error) {//add post bodyvar bodyJson []bytevar req *http.Requestif body != nil {var err errorbodyJson, 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")//add paramsq := req.URL.Query()if params != nil {for key, val := range params {q.Add(key, val)}req.URL.RawQuery = q.Encode()}//add headersif headers != nil {for key, val := range headers {req.Header.Add(key, val)}}//http clientclient := &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

//Get http get methodfunc Get(url string, params map[string]string, headers map[string]string) ([]byte, error) {//new requestreq, err := http.NewRequest("GET", url, nil)if err != nil {log.Println(err)return nil, errors.New("new request is fail ")}//add paramsq := req.URL.Query()if params != nil {for key, val := range params {q.Add(key, val)}req.URL.RawQuery = q.Encode()}//add headersif headers != nil {for key, val := range headers {req.Header.Add(key, val)}}//http clientclient := &http.Client{}log.Printf("Go GET URL : %s \n", req.URL.String())//发送请求res, err := client.Do(req)if err != nil {return nil, err}defer res.Body.Close() //一定要关闭res.Body//读取bodyresBody, err := ioutil.ReadAll(res.Body) //把 body 内容读入字符串 sif err != nil {return nil, err}return resBody, nil}

2、POST请求

//Post http post methodfunc Post(url string, body map[string]interface{}, params map[string]string, headers map[string]string) ([]byte, error) {//add post bodyvar bodyJson []bytevar req *http.Requestif body != nil {var err errorbodyJson, 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")//add paramsq := req.URL.Query()if params != nil {for key, val := range params {q.Add(key, val)}req.URL.RawQuery = q.Encode()}//add headersif headers != nil {for key, val := range headers {req.Header.Add(key, val)}}//http clientclient := &http.Client{}log.Printf("Go POST URL : %s \n", req.URL.String())//发送请求res, err := client.Do(req)if err != nil {return nil, err}defer res.Body.Close() //一定要关闭res.Body//读取bodyresBody, err := ioutil.ReadAll(res.Body) //把 body 内容读入字符串 sif err != nil {return nil, err}return resBody, nil}
