Python3接口性能测试实例代码

首先来看实例代码：

# -*- coding:utf-8 -*-


import requests
import datetime
import time
import 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ms
ThinkTime = 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

实例扩展：

利用ruquest发送请求，利用多线程模拟并发
