先创建一个解析请求的服务

package main

import (
	"fmt"
	"github.com/gin-gonic/gin"
)

func main() {
	router := gin.Default()
	router.POST("/post", PostFunc)
	router.GET("/get", GetFunc)
	router.Run(":5000")
}

func GetFunc(c *gin.Context) {
	name := c.Query("name")
	age := c.Query("age")
	uri:=c.Request.URL.RawQuery
	fmt.Println(name)
	fmt.Println(age)
	fmt.Println(uri)
}

func PostFunc(c *gin.Context) {
	buf := make([]byte, 1024)
	n, _ := c.Request.Body.Read(buf)
	fmt.Println(string(buf[0:n]))
}

下面是提交请求的功能

package main

import (
	"fmt"
	"io/ioutil"
	"net/http"
	"strings"
)

func main() {
	fmt.Println(getReq("zhangsan", "18"))
	postReq("lisi", 19)
}

func getReq(name string, age string) string {
	client := &http.Client{}

	req, err := http.NewRequest("GET", "http://localhost:5000/get",
		nil)
	if err != nil {
		panic(err)
	}
	query := req.URL.Query()
	query.Add("name", name)
	query.Add("age", age)
	req.URL.RawQuery = query.Encode()

	resp, err := client.Do(req)

	defer resp.Body.Close()

	body, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		panic(err)
	}

	resdata := string(body)
	return resdata

}

func postReq(name string, age int) {
	client := &http.Client{}

	req, err := http.NewRequest("POST", "http://localhost:5000/post",
		strings.NewReader(fmt.Sprintf("name=%s&age=%d", name, age)))
	if err != nil {
		panic(err)
	}

	req.Header.Set("Content-Type", "application/x-www-form-urlencoded")

	resp, err := client.Do(req)

	defer resp.Body.Close()

}
