Http请求

最近在项目中模拟http请求比较多，总结了一下go语言中的各种http请求

package main

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

// 发送简单的GET请求
func SendSimpleGetRequest() {
    resp, err := http.Get("https://baidu.com")
    if err != nil {
        panic(err)

    }
    defer resp.Body.Close()
    s, err := ioutil.ReadAll(resp.Body)
    fmt.Printf(string(s))
}

// 发送复杂的Get请求
func SendComplexGetRequest() {
    params := url.Values{}

    Url, err := url.Parse("http://baidu.com?fd=fdsf")
    if err != nil {
        panic(err.Error())

    }
    params.Set("a", "fdfds")
    params.Set("id", string("1"))
    //如果参数中有中文参数,这个方法会进行URLEncode
    Url.RawQuery = params.Encode()
    urlPath := Url.String()
    resp, err := http.Get(urlPath)
    defer resp.Body.Close()
    s, err := ioutil.ReadAll(resp.Body)
    fmt.Println(string(s))
}

// 使用PostForm进行请求
func httpPostForm() {
    // params:=url.Values{}
    // params.Set("hello","fdsfs")  //这两种都可以
    params := url.Values{"key": {"Value"}, "id": {"123"}}
    resp, _ := http.PostForm("http://baidu.com", params)

    defer resp.Body.Close()
    body, _ := ioutil.ReadAll(resp.Body)

    fmt.Println(string(body))

}

// 通用的http请求
func httpDo() {
    client := &http.Client{}

    urlmap := url.Values{}

    urlmap.Add("client_id", "esss")
    urlmap.Add("client_secret", "sk")
    parms := ioutil.NopCloser(strings.NewReader(urlmap.Encode())) //把form数据编下码
    req, err := http.NewRequest("POST", "www.baidu.com", parms)
    if err != nil {
        // handle error
    }

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

    resp, err := client.Do(req)

    defer resp.Body.Close()

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

    fmt.Println(string(body))
}
func main() {
    httpDo()
}
