昨天學了一天的Python（我的生產語言是java，也可以寫一些shell腳本，算有一點點基礎），今天有一個應用場景，就正好練手了。

這個功能之前再java里寫過，比較粗糙，原來是在我本機跑的，今天老大要求要隨時保持請求，就用Python改寫了下，省的又把一個有跟多雜項的jar包傳到服務器，省空間又不亂，而且好讀。

先附上java代碼：

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

(代碼里的參數地址等我已做了隱藏，json格式可能不準確了，無所謂)

接下來上Python代碼：

#!/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 = ["-中文測試-，","-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()
