php 、go 、python http请求（get和post）

php get、post体验

php的get请求通过file_get_contents  直接请求

以下是post表单提交

function curl_post($url,  $params = array(), $timeout = 8)
    {
        $ch = curl_init();//初始化curl
        curl_setopt($ch, CURLOPT_URL, $url);//抓取指定网页
        curl_setopt($ch, CURLOPT_HEADER, 0);//设置header
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
        curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
        curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
        $data = curl_exec($ch);//运行curl
        curl_close($ch);
        return ($data);//输出结果
    }

以下是直接提交json数据提交

function curl_post_json($url, $params, $timeout = 8)
    {
        $headers = array(
            "Content-type: application/json;charset='utf-8'",
            "Accept: application/json",
            "Cache-Control: no-cache",
            "Pragma: no-cache",
        );
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_TIMEOUT, 60); //设置超时
        if(0 === strpos(strtolower($url), 'https')) {
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); //对认证证书来源的检查
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); //从证书中检查SSL加密算法是否存在
        }
        curl_setopt($ch, CURLOPT_POST, TRUE);
        curl_setopt($ch, CURLOPT_POSTFIELDS, ($params));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        $data = curl_exec($ch);//CURLOPT_RETURNTRANSFER 不设置  curl_exec返回TRUE 设置  curl_exec返回json(此处) 失败都返回FALSE
        curl_close($ch);
        return ($data);//输出结果
    }

 

python2.6 和 python3 get、post 体验

总体感觉3对中文支持比较明显，但是post里面有坑，一般的post都还行，强烈建议后期开发用python2.6，相对成熟

python3 

# coding:utf-8


from urllib import request
from urllib import parse

def get():
    url = "http://120.26.39.165:28006/api/v1/park-num"
    req = request.Request(url)  # GET方法
    page = request.urlopen(req).read()
    page = page.decode('utf-8')
    return page


def post():
    sdata = '{"all":9582,"overground_cars":{"parkUuid":"","floorUuid":"","parkName":"\u82cf\u5dde\u5965\u4f53\u4e2d\u5fc3","floorName":"\u5730\u4e0a","leftNum":6615},"floor_car":[{"parkUuid":"cab11551985b4c73959649adda514b0d","parkName":"\u82cf\u5dde\u5965\u4f53\u4e2d\u5fc3","floorUuid":"847cc63e5d114c9982d51684b6eb9d1e","floorName":"2\u53f7\u8f66\u5e93","leftNum":514},{"parkUuid":"cab11551985b4c73959649adda514b0d","parkName":"\u82cf\u5dde\u5965\u4f53\u4e2d\u5fc3","floorUuid":"9dc655eaca6047f8a3aca399de503445","floorName":"B1","leftNum":910},{"parkUuid":"cab11551985b4c73959649adda514b0d","parkName":"\u82cf\u5dde\u5965\u4f53\u4e2d\u5fc3","floorUuid":"1b3b52fdef3843f1b4f8b9fd61285ff9","floorName":"B2","leftNum":187}]}';


    url = "http://120.26.39.165:28006/api/v1/insert_num"
    headers = {
        'User-Agent': r'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) '

        'Connection': 'keep-alive'
    }

    data = {
        'cont': sdata
    }
    data = parse.urlencode()
    data = parse.urlencode(data).encode('utf-8')
    req = request.Request(url, headers=headers, data=data)
    page = request.urlopen(req).read()
    page = page.decode('utf-8')
    return page

s = post()
print(s)

go语言的get、post请求

get请求

package main

import (
   "net/http"
   "io/ioutil"
   "fmt"
   "github.com/go-irain/logger"
   "strings"
   "net"
   "time"
   "os"
   "io"
)

func get() {
   res, err := http.Get("https://www.hao123.com")
   if err!= nil{
      panic(err)
   }
   getRes , err := ioutil.ReadAll(res.Body)
   if err!= nil{
      panic(err)
   }
   fmt.Println(string(getRes))
}

func post()  {
   url := "http://cmb.com"
   param := "name=aa"
   /*     生成client,参数默认;
    *    这个结构体有四个属性
    *    Transport(RoundTrepper);指定执行的独立、单次http请求的机制
    *    CheckRedirect(func(req *Request, via []*Request)err):指定处理重定向的策略,如果不为nil,客户端在执行重定向之前调用本函数字段.如果CheckRedirect 返回一个错误，本类型中的get方法不会发送请求,如果CheckRedirect为nil,就会采用默认策略:连续请求10次后停止；
    ＊    jar(CookieJar):jar指定cookie管理器,若果为nil请求中不会发送cookie,回复中的cookie会被忽略
    ＊    TimeOut(time.Duration):指定本类型请求的时间限制，为0表示不设置超时
    */
   //client := &http.Client{}    这里初始化了一个默认的client，并没有配置一些请求的设置

   //可以通过client中transport的Dail函数,在自定义Dail函数里面设置建立连接超时时长和发送接受数据超时
   client := &http.Client{
      Transport: &http.Transport{
         Dial: func(netw, addr string) (net.Conn, error) {
            conn, err := net.DialTimeout(netw, addr, time.Second*2)    //设置建立连接超时
            if err != nil {
               return nil, err
            }
            conn.SetDeadline(time.Now().Add(time.Second * 2))    //设置发送接受数据超时
            return conn, nil
         },
         ResponseHeaderTimeout: time.Second * 2,
      },
   }
   reqest,err := http.NewRequest("POST",url,strings.NewReader(param))    //提交请求;用指定的方法，网址，可选的主体放回一个新的*Request
   reqest.Header.Set("Content-Type","application/x-www-form-urlencoded")
   if err != nil {
      panic(err)
      return
   }
   response,err := client.Do(reqest)    //前面预处理一些参数，状态，Do执行发送；处理返回结果;Do:发送请求,
   defer response.Body.Close()
   stdout := os.Stdout            //将结果定位到标准输出，也可以直接打印出来，或定位到其他地方进行相应处理
   _,err = io.Copy(stdout,response.Body)    //将第二个参数拷贝到第一个参数，直到第二参数到达EOF或发生错误，返回拷贝的字节喝遇到的第一个错误.
   status := response.StatusCode        //获取返回状态码，正常是200
   body,err := ioutil.ReadAll(response.Body)
   logger.Info(string(body))
   logger.Info(status)
}

func main() {
   post()
}
