#coding=utf8 ''' random.randint(a, b):用于生成一个指定范围内的整数。 其中参数a是下限,参数b是上限,生成的随机数n: a <= n <= b random.choice(sequence):从序列中获取一个随机元素 参数sequence表示一个有序类型(列表,元组,字符串) ''' import httplib,json import time import threading from random import randint,choice #创建请求函数 def postRequest(threadNum): postJson = { } #定义需要进行发送的数据 postData = json.dumps(postJson) #定义一些文件头 headerdata = { "content-type" : "application/json" , } #接口 requrl = "/v1/query" #请求服务,例如:www.baidu.com hostServer = "" #连接服务器 conn = httplib.HTTPConnection(hostServer) #发送请求 conn.request(method = "POST" ,url = requrl,body = postData,headers = headerdata) #获取请求响应 response = conn.getresponse() #打印请求状态 if response.status in range ( 200 , 300 ): print u "线程" + str (threadNum) + u "状态码:" + str (response.status) conn.close() def run(threadNum,internTime,duration): #创建数组存放线程 threads = [] try : #创建线程 for i in range ( 1 ,threadNum): #针对函数创建线程 t = threading.Thread(target = postRequest,args = (i,)) #把创建的线程加入线程组 threads.append(t) except Exception,e: print e try : #启动线程 for thread in threads: thread.setDaemon( True ) thread.start() time.sleep(internTime) #等待所有线程结束 for thread in threads: thread.join(duration) except Exception,e: print e if __name__ = = '__main__' : startime = time.strftime( "%Y%m%d%H%M%S" ) now = time.strftime( "%Y%m%d%H%M%S" ) duratiion = raw_input (u "输入持续运行时间:" ) while (startime + str (duratiion))! = now: run( 10 , 1 , int (duratiion)) now = time.strftime( "%Y%m%d%H%M%S" ) |
运行结果:
希望本文所述对大家Python程序设计有所帮助。
