Python3接口性能测试实例代码 Python3接口性能测试实例代码

首先来看实例代码：

# -*- coding:utf-8 -*-import requestsimport datetimeimport timeimport threading'''allow_redirects = False禁止重定向，添加在request参数后get请求用params传参post请求，数据类型form，用data传参post请求，数据类型form，用data传参post请求，数据类型json，json传参timeout:请求超时时间，添加在request参数后nub = 10#设置并发线程数ResponseTime=float(result.elapsed.microseconds)/1000 #获取响应时间，单位msThinkTime = 0.5#设置思考时间AverageTime = "{:.3f}".format(float(sum(myrequest.times))/float(len(myrequest.times)))#计算数组的平均值，保留3位小数totaltime = float(hour)*60*60 + float(minute)*60 + float(second) #计算总的思考时间+请求时间'''class url_request:times = []error = []def weather_DC(self):myrequest=url_request()weatherinfo_search = 'https://restapi.amap.com/v3/weather/weatherInfo?parameters'params = {'key': 'cd1b11e80ffac05253196aa2a1233f25','city': 110101,'extensions': 'base','output': 'JSON'}result = requests.get(url=weatherinfo_search, params=params)print("状态码：",result.status_code)print("返回报文：",result.text)ResponseTime=float(result.elapsed.microseconds)/1000myrequest.times.append(ResponseTime)if result.status_code !=200 :myrequest.error.append("0")if __name__=='__main__':myrequest=url_request()threads = []starttime = datetime.datetime.now()print("请求开始时间：request start time %s" %starttime)nub = 10ThinkTime = 0.5for i in range(1, nub+1):t = threading.Thread(target=myrequest.weather_DC())threads.append(t)for t in threads:time.sleep(ThinkTime)print("线程数：thread %s" %t)t.setDaemon(True)t.start()t.join()endtime = datetime.datetime.now()print("请求结束时间：request end time %s" %endtime)time.sleep(3)AverageTime = "{:.3f}".format(float(sum(myrequest.times))/float(len(myrequest.times)))print("平均响应时间：Average Response Time %s ms" %AverageTime)usetime = str(endtime - starttime)hour = usetime.split(':').pop(0)minute = usetime.split(':').pop(1)second = usetime.split(':').pop(2)totaltime = float(hour)*60*60 + float(minute)*60 + float(second)print("并发数：Concurrent processing %s" %nub)print("#总共消耗的时间：use total time %s s" %(totaltime-float(nub*ThinkTime)))print("错误请求数：fail request %s s" %myrequest.error.count("0"))

实例扩展：
利用ruquest发送请求，利用多线程模拟并发
