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：
packagexxxxxx.base;
importjava.util.Random;
importorg.apache.commons.lang3.StringUtils;
importhaojianxiang.util.HttpRequest;
publicclassCreateFeedbackData{
publicstaticvoidmain(String[]args){
while(true){
try{
Randomr=newRandom();
intsleep=r.nextInt(1200000)+600000;
Thread.sleep(sleep);
post();
}catch(Exceptione){
e.printStackTrace();
}
}
}
publicstaticvoidpost(){
Stringurl="http://111.111.111.111:8080/xxxx/post";
int[]types={1,2,3,4};
intindex=(int)(Math.random()*types.length);
inttype=types[index];
//String[]contents={"-中文测试-，","-EnglishTest-,","~!@#$%^&*()_;:'-\"<>?/|\\-,",""};
String[]contents={"-中文测试-，","-EnglishTest-,","~!@#$%,",""};
StringBuffercontent=newStringBuffer();
content.append("haojianxiangtest:");
for(inti=0;i<10;i++){
intidx=(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",
};
StringBufferimg=newStringBuffer();
for(inti=0;i<(int)(Math.random()*4);i++){
intlucky=(int)(Math.random()*2);
if(lucky==1){
intidx=(int)(Math.random()*imgs.length);
img.append(imgs[idx]);
img.append(",");
}
}
StringimgStr="";
if(StringUtils.isNotBlank(img)){
imgStr=img.substring(0,img.length()-1);
}
Stringparam="{\"req\":{\"userId\":xxxxxx},"+
"\"data\":{"\"fbType\":"+type+",\"fbContent\":\""+content.toString()+
"\",\"fbPic\":\""+imgStr+"\"}}";
Stringrst=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/envpython
#-*-coding:utf-8-*-
importrandom
importurllib
importurllib.request
importtime
defpostFeedBack():
url="http://111.111.111.111:8080/xxxx/post"
type=int(random.uniform(1,5))
contents=["-中文测试-，","-EnglishTest-,","~!@#$%,",""]
content="haojianxiangtest:"
foriinrange(0,10):
content+=random.choice(contents)
img=""
imgs=["/Upload/58c7b315cb39f.jpg",
"/Upload/58cb467a69873.jpg",
"/Upload/58afff0e99432.png",
"/Upload/58b545539eb80.jpg",
"/Upload/58b55d7c9e281.JPG"]
foriinrange(0,3):
lucky=int(random.uniform(0,2))
iflucky==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__":
whileTrue:
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。
