Python批量发送post请求的实现代码

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() 

Python的写法确实很简洁高效（java代码里post的逻辑，我还是调用了自己的一个工具类，实际代码要更多），今后打算把Python作为优先脚本语言，处理简单问题很快。
