昨天學了一天的Python（我的生產語言是java，也可以寫一些shell指令碼，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裡寫過，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包傳到伺服器，省空間又不亂，而且好讀。

先附上java程式碼：

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

}
 

接下來上Python程式碼：

#!/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-,","
 
[email protected]#$%,","     "]
    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()
