go 网络请求篇

---恢复内容开始---

今天特意找了下go的网络请求篇，get请求是ok的，post请求一直不下来，搜索了下，代码都差不多，无法拿到post数据，先整理一篇，亲测可用。

针对post ，先来说下post 四种提交数据方式（Content-Type）  链接

• application/x-www-form-urlencoded      key1=val1&key2=val2       PHP 中，$_POST['title'] 可以获取到 title 的值，$_POST['sub'] 可以得到 sub 数组。
• multipart/form-data     文件上传
• application/json    在请求头中 Content-Type 为 application/json 时，从 php://input 里获得原始输入流

 

• text/xml       不熟悉

 

  我当时测试的为php接口，然后content-type 写成了 application/json，然后怎么post都是拿到的域名的html页面代码。以下为测试通过代码

　　　　

 

1、get请求

package main

import (
    "bytes"
    "fmt"
    "log"
    "net/http"
    "reflect"
)

func main() {

    url := "http://api.budejie.com/api/api_open.php?a=list&appname=baisibudejie_hd&asid=C1180CB8-F460-4385-A77C-97CD1AA83DFD&c=data&client=ipad&device=ios%20%E8%AE%BE%E5%A4%87&from=ios&jbk=0&mac=02:00:00:00:00:00&market=&maxtime=&openudid=78336166d6a434b4cf1634410eb3b692d6d3a4ee&order=ctime&page=1&per=20000&systemversion=7.1&type=10&ver=2.0.3"

    resp, err := http.Get(url)

    if err != nil {
        // 错误处理
        log.Println(err)
        return
    }

    defer resp.Body.Close() //关闭链接

    fmt.Printf("resp status %s,statusCode %d
", resp.Status, resp.StatusCode)

    fmt.Printf("resp Proto %s
", resp.Proto)

    fmt.Printf("resp content length %d
", resp.ContentLength)

    fmt.Printf("resp transfer encoding %v
", resp.TransferEncoding)

    fmt.Printf("resp Uncompressed %t
", resp.Uncompressed)

    fmt.Println(reflect.TypeOf(resp.Body))
    buf := bytes.NewBuffer(make([]byte, 0, 512))
    length, _ := buf.ReadFrom(resp.Body)
    fmt.Println(len(buf.Bytes()))
    fmt.Println(length)
    fmt.Println(string(buf.Bytes()))
}

2、post请求

package mainimport ("bytes""fmt""io/ioutil""net/http""net/url""time"
)func main() {url := "http://api.budejie.com/api/api_open.php"var data map[string]string /*创建集合 */data = make(map[string]string)data["a"] = "list"data["appname"] = "baisibudejie_hd"data["asid"] = "C1180CB8-F460-4385-A77C-97CD1AA83DFD"data["c"] = "data"data["client"] = "ipad"data["device"] = "ios"data["from"] = "ios"data["jbk"] = "0"data["mac"] = "02:00:00:00:00:00"data["openudid"] = "78336166d6a434b4cf1634410eb3b692d6d3a4ee"data["order"] = "ctime"data["page"] = "1"data["per"] = "20"data["systemversion"] = "7.1"data["type"] = "10"data["ver"] = "2.0.3"data["market"] = ""data["maxtime"] = ""contentType := "application/x-www-form-urlencoded"json := Post(url, data, contentType)fmt.Println(json)}//发送POST请求
//url:请求地址，data:POST请求提交的数据,contentType:请求体格式，如：application/json
//content:请求放回的内容
func Post(urlStr string, data map[string]string, contentType string) (content string) {postValues := url.Values{}for postKey, PostValue := range data {postValues.Set(postKey, PostValue)}postDataStr := postValues.Encode()postDataBytes := []byte(postDataStr)postBytesReader := bytes.NewReader(postDataBytes)req, err := http.NewRequest("POST", urlStr, postBytesReader)req.Header.Add("content-type", contentType)if err != nil {panic(err)}defer req.Body.Close()client := &http.Client{Timeout: 5 * time.Second}resp, error := client.Do(req)if error != nil {panic(error)}defer resp.Body.Close()result, _ := ioutil.ReadAll(resp.Body)content = string(result)return
}
