#URL

req = urllib2.Request(‘http://47.93.169.69:10080/pigeon-web/user/userExtraInfo?userId=1‘)

rule = {0:500,1:30}

Rule规则：0:50，第一次运行不睡眠即为0，直接并发50次；1:20，第二秒，相当于睡眠1秒，然后并发20次，

如第三秒需并发500次，则rule = {0:50,1:20,1:500}

#Open url

def geturl():

    time_b = time.time()

    try:

        response = urllib2.urlopen(req)

        print(response.read().decode("utf-8"))  # 打印输出内容

    except urllib2.URLError as e:

        if hasattr(e, ‘reason‘):

            print(‘We failed to reach a server.‘)

            print(‘Reason: ‘, e.reason)

        elif hasattr(e, ‘code‘):

            print(‘The server couldn\‘t fulfill the request.‘)

            print(‘Error code: ‘, e.code)

    time_e = time.time()

    print("Thread %s runned for %ss" % (threading.current_thread().name, (time_e - time_b)))  #线程访问时效

if __name__==‘__main__‘:

    for k in rule:

        time.sleep(k)

        for i in range(rule[k]):

            t = threading.Thread(target=geturl)

            t.start()
