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()
Python的寫法確實很簡潔高效（java代碼里post的邏輯，我還是調用了自己的一個工具類，實際代碼要更多），今后打算把Python作為優先腳本語言，處理簡單問題很快。
