使用aiohttp的一个小例子

#!/usr/bin/env python  
# encoding: utf-8  
import aiohttp
import asyncio
import traceback
import time
import random
TEST_URL="http://www.baidu.com"
CODE=[200]
class TestAio(object):
    async  def getbaidu(self):
        conn=aiohttp.TCPConnector(verify_ssl=False) #忽略证书错误
        async with aiohttp.ClientSession(connector=conn) as session:
            try:
                async with session.get(TEST_URL,timeout=15) as response:
                    if response.status in CODE:
                        print(response.text)
            except:
                print(traceback.format_exc())

    def run(self):
        try:
            loop=asyncio.get_event_loop()
            for i in range(0,100,10):
                tasks=[self.getbaidu()  for i in range(0,10)]
                loop.run_until_complete(asyncio.wait(tasks))
                time.sleep(random.randint(1,5))
        except:
            print(traceback.format_exc())
