Python批量发送post请求的实现代码_Python

昨天学了一天的Python（我的生产语言是java，也可以写一些shell脚本，算有一点点基础），今天有一个应用场景，就正好练手了。

这个功能之前再java里写过，比较粗糙，原来是在我本机跑的，今天老大要求要随时保持请求，就用Python改写了下，省的又把一个有跟多杂项的jar包传到服务器，省空间又不乱，而且好读。

先附上java代码：

									package xxxxxx.base;  

									import java.util.Random;  

									import org.apache.commons.lang3.StringUtils;  

									import haojianxiang.util.HttpRequest;  

									public class CreateFeedbackData { 

									  public static void main(String[] args) { 

									    while (true) { 

									      try { 

									        Random r = new Random(); 

									        int sleep = r.nextInt(1200000) + 600000; 

									        Thread.sleep(sleep); 

									        post(); 

									      } catch (Exception e) { 

									        e.printStackTrace(); 

									      } 

									    } 

									  } 

									  public static void post(){ 

									    String url = "http://111.111.111.111:8080/xxxx/post"; 

									    int[] types = {1, 2, 3, 4}; 

									    int index = (int) (Math.random() * types.length); 

									    int type = types[index]; 

									//   String[] contents = {"-中文测试-，","-English Test-,","~!@#$%^&*()_;:'-\"<>?/|\\-,","     "}; 

									    String[] contents = {"-中文测试-，","-English Test-,","~!@#$%,","     "}; 

									    StringBuffer content = new StringBuffer(); 

									    content.append("haojianxiang test:"); 

									    for (int i = 0; i < 10; i++) { 

									      int idx = (int) (Math.random() * contents.length); 

									      content.append(contents[idx]); 

									    } 

									    String[] imgs = {"/Upload/appUpload/58c7b315cb39f.jpg", 

									        "/Upload/appUploa/58cb467a69873.jpg", 

									        "/Upload/appUpload/58afff0e99432.png", 

									        "/Upload/appUpload/58b545539eb80.jpg", 

									        "/Upload/appUpload/58b55d7c9e281.JPG", 

									    }; 

									    StringBuffer img = new StringBuffer(); 

									    for (int i = 0; i < (int) (Math.random() * 4); i++) { 

									      int lucky = (int) (Math.random() * 2); 

									      if (lucky == 1) { 

									        int idx = (int) (Math.random() * imgs.length); 

									        img.append(imgs[idx]); 

									        img.append(","); 

									      } 

									    } 

									    String imgStr = ""; 

									    if (StringUtils.isNotBlank(img)) { 

									      imgStr = img.substring(0, img.length()-1); 

									    } 

									    String param = "{\"req\":{\"userId\":xxxxxx}," + 

									        "\"data\":{"\"fbType\":" + type + ",\"fbContent\":\""+content.toString()+ 

									        "\",\"fbPic\":\""+imgStr+"\"}}"; 

									    String rst = HttpRequest.sendPost(url, param); 

									    System.out.println("TIME--"+ System.currentTimeMillis() + " result:" + rst); 

									  } 

									}

(代码里的参数地址等我已做了隐藏，json格式可能不准确了，无所谓)

接下来上Python代码：

									#!/usr/bin/env python 

									# -*- coding: utf-8 -*- 

									import random 

									import urllib 

									import urllib.request 

									import time 

									def postFeedBack(): 

									  url = "http://111.111.111.111:8080/xxxx/post"

									  type = int(random.uniform(1,5)) 

									  contents = ["-中文测试-，","-English Test-,","~!@#$%,","   "] 

									  content = "haojianxiang test:"

									  for i in range(0,10): 

									    content += random.choice(contents) 

									  img = "" 

									  imgs = ["/Upload/58c7b315cb39f.jpg", 

									      "/Upload/58cb467a69873.jpg", 

									      "/Upload/58afff0e99432.png", 

									      "/Upload/58b545539eb80.jpg", 

									      "/Upload/58b55d7c9e281.JPG"] 

									  for i in range(0,3): 

									    lucky = int(random.uniform(0,2)) 

									    if lucky == 1: 

									      img += random.choice(imgs) 

									      img += ","

									  img = img[:-1] 

									  data = "{\"req\":{\"userId\": xxx},"

									  data += "\"data\":{ 

									  data += "\"fbType\":"

									  data += str(type) 

									  data += ",\"fbContent\":\""

									  data += content 

									  data += "\",\"fbPic\":\""

									  data += img 

									  data += "\"}}"

									  pdata = bytes(data,encoding="utf-8") 

									  f = urllib.request.urlopen(url,pdata) 

									  result = f.read() 

									  result = result.decode('UTF-8') 

									  print(result) 

									if __name__ == "__main__": 

									  while True: 

									    st = int(random.uniform(600,1800)) 

									    print("sleep:",st) 

									    time.sleep(st) 

									    postFeedBack()
