golang request body query 请求方式封装

创建一个 requests目录，在requests目录下创建一个request.go文件，内容如下

package requests

import (
	"bytes"
	"encoding/json"
	"io/ioutil"
	"net/http"
)

func Error(err error) (interface{}, error) {
	return nil, err
}

type Request struct {
	Url     string
	Method  string
	Data    map[string]string
	Headers map[string]string
	ReqInfo map[string]interface{}
}

func (r *Request) Body() (map[string]interface{}, error) {
	data, err := json.Marshal(r.Data)
	Error(err)
	client := &http.Client{}
	req, err := http.NewRequest(r.Method, r.Url, bytes.NewBuffer(data))
	Error(err)
	req.Header.Add("Content-Type", "application/json;charset=UTF-8")
	for k, v := range r.Headers {
		req.Header.Add(k, v)
	}
	rep, err := client.Do(req)
	Error(err)
	defer rep.Body.Close()
	body, err := ioutil.ReadAll(rep.Body)
	Error(err)
	if err = json.Unmarshal(body, &r.ReqInfo); err != nil {
		return nil, err
	}
	return r.ReqInfo, nil
}

func (r *Request) Query() (map[string]interface{}, error) {
	client := &http.Client{}
	req, err := http.NewRequest(r.Method, r.Url, nil)
	Error(err)
	req.Header.Add("Content-Type", "application/json;charset=UTF-8")
	for k, v := range r.Headers {
		req.Header.Add(k, v)
	}
	query := req.URL.Query()
	for k, v := range r.Data {
		query.Add(k, v)
	}
	req.URL.RawQuery = query.Encode()
	rep, err := client.Do(req)
	Error(err)
	rep.Body.Close()
	body, err := ioutil.ReadAll(rep.Body)
	Error(err)
	err = json.Unmarshal(body, &r.ReqInfo)
	Error(err)
	return r.ReqInfo, nil
}
