python压力测试脚本_压力测试的脚本怎么写

一正常情况测试
 
import json
import requests
import logging
 
logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')
logger = logging.getLogger(__name__)
 
restime = []
OK=[]
class Restime():
    def API(self,URL2,param):
 
        try:
            r = requests.get(URL2, params=param, timeout=10)
            r.raise_for_status()  # 如果响应状态码不是 200，就主动抛出异常
        except requests.RequestException as e:
            print(e)
        else:
            js = json.dumps(r.json())
            return [r.json(), r.elapsed.total_seconds(),js]
 
    def circulation(self,num,URL2,param):
 
 
        for i in range(num):
 
            restime.append(Restime.API(URL2,param)[1])
            if json.loads(Restime.API(URL2, param)[2])["message"]=='ok':
                OK.append(json.loads(Restime.API(URL2, param)[2])["message"])
                logger.info('请求第' + str(i+1) + '次，请求'+json.loads(Restime.API(URL2, param)[2])["message"]+',状态码：'+json.loads(Restime.API(URL2, param)[2])["status"])
            else:
                logger.info('请求第' + str(i+1) + '次，请求' + json.loads(Restime.API(URL2, param)[2])["message"] + ',状态码：' +
                            json.loads(Restime.API(URL2, param)[2])["status"])
 
        print('测试次数：',num)
        print('响应次数：', len(restime))
        print('正常响应次数：', len(OK))
        print('总响应最大时长：', max(restime))
        print('总响应最小时长：', min(restime))
        print('总响应时长：', sum(restime))
        print('平均响应时长：', sum(restime) / len(restime))
 
 
if __name__ == '__main__':
    Restime=Restime()
    num=500 #压力测试次数
    URL2 = 'http://www.kuaidi100.com/query'  #地址
    param = {'type' : 'zhongtong' , 'postid' :'73116039505988' }  #参数
    Restime.circulation(num,URL2,param)
 
 
 
 
 
 
 
二多线程测试
 
import datetime
import json
import requests
import logging
import threading
import time
import sys
from time import sleep,ctime
logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')
logger = logging.getLogger(__name__)
 
reponse_time = []
OK = []
 
 
class runScript():
    def API(self, url, params):
        try:
            r = requests.get(url, params=params, timeout=10)
            r.raise_for_status()  # 如果响应状态码不是 200，就主动抛出异常
        except requests.RequestException as e:
            print(e)
        else:
            js = json.dumps(r.json())
            # print(r.json()) #json格式的响应数据
            # print(r.elapsed.total_seconds())　响应时间
            # print(js)　没有解码的响应数据
            return [r.json(), r.elapsed.total_seconds(), js]
 
    def circulation(self,url, params):
        # print(Restime.API(url, params)[0]['message'])
        reponse_time.append(self.API(url, params)[1])
        datas = json.loads(self.API(url, params)[2])["message"]
        status = json.loads(self.API(url, params)[2])["status"]
        if datas == 'ok':
            OK.append(datas)
            logger.info('请求状态为：' + datas + ',状态码为：' + status)
        else:
            logger.info('请求状态为：' + datas + ',状态码为：' + status)
 
 
def test(url,params):
    Restime = runScript()
    Restime.circulation(url, params)
 
def main(num,url,params):
    # print("Starting at:",ctime())
    start_time = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
    threads = []
    for i in range(num):
        t = threading.Thread(target=test,args=(url,params))
        threads.append(t)
    for t in range(num):
        threads[t].start()
    for j in range(num):
        threads[j].join()
    # print("All done at:",ctime())
    print("Starting at:",start_time)
    print("All done at:",datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'))
    # print(OK)
    print('响应次数：', len(reponse_time))
    print('正常响应次数：', len(OK))
    print('总响应最大时长：', max(reponse_time))
    print('总响应最小时长：', min(reponse_time))
    print('总响应时长：', sum(reponse_time))
    print('平均响应时长：', sum(reponse_time) / len(reponse_time))
    # print('QPS（TPS）= 并发数/平均响应时间:',num  / (sum(reponse_time) / len(reponse_time)))
 
if __name__ == '__main__':
    num = input('输入需要开启的线程数量:')
    url = 'http://www.kuaidi100.com/query'  #地址
    params = {'type': 'zhongtong', 'postid': '73116039505988'}  #参数
    main(int(num),url,params)
