python locust 性能测试：HttpSession

　　官网解释：用于在请求之间执行Web请求和保留（会话）cookie的类（以便能够登录和退出网站）；记录每个请求，以便locust可以显示统计信息；

from locust import TaskSet, task, HttpLocust, Locust
from locust.clients import HttpSession
import subprocess
import random
from common.sec_encrypt import AESEncrypt, md5_time
from common import read_config
from common.logger import print_file

class WebUser(TaskSet):
    def on_start(self):
        self.session = HttpSession(‘http://localhost:8000/api‘)
        self.r = random.randint(10000, 99999)

    @task(2)
    def user_auth(self):
        """用户认证"""
        auth_user = (‘lixiaofeng‘, ‘fengzi802300‘)
        res = self.session.get(‘/sec_get_event_list/‘, params={‘eid‘: self.r}, auth=auth_user,
                               name=‘/sec_get_event_list/?eid=[eid]‘)
        print_file(res.json())
        # assert res.json()[‘status‘] == 200, ‘用户认证接口请求失败！‘

    @task(1)
    def aes_api(self):
        payload = {‘name‘: ‘187187011{}‘.format(self.r)}
        # 加密
        encodeed = AESEncrypt(payload).encrypt_data()
        # print(encodeed)
        res = self.session.get(‘/sec_get_guest_list/‘, params={‘data‘: encodeed},
                               name=‘/sec_get_guest_list/?data=[aes]‘)
        print_file(res.text)
        # assert res.json()[‘status‘] == 200, ‘AES接口加密请求失败！‘

    @task(2)
    def md5_api(self):
        payload = {"eid": "{}".format(self.r), "name": "一加8手机发布会{}".format(str(self.r)), "limit": 2000, "status": "1",
                   "address": "深圳宝体会展中心",
                   "start_time": "2019-09-15 22:40:00", ‘time‘: ‘‘, ‘sign‘: ‘‘}
        payload = md5_time(payload)
        res = self.session.post(‘/sec_add_event/‘, data=payload, name=‘/sec_add_event/?data=[md5]‘)
        print_file(res.text)
        # assert res.json()[‘status‘] == 200, ‘md5接口加密请求失败！‘

    @task(2)
    def add_guest(self):
        """添加嘉宾"""
        payload = {‘eid‘: ‘{}‘.format(self.r), ‘realname‘: ‘赵小刀{}‘.format(self.r),
                   ‘phone‘: ‘187011{}‘.format(self.r),
                   ‘email‘: ‘187011{}@163.com‘.format(self.r)}
        res = self.session.post(‘/add_guest/‘, data=payload, name=‘/add_guest/?data=[payload]‘)
        print_file(res.text)

class Run(Locust):
    # host = ‘http://localhost:8000/api‘
    task_set = WebUser
    max_wait = 6000
    min_wait = 3000

def run():    subprocess.check_call(        ‘locust -f D:\Interface_framework_Beauty\locust_files\\locust_test.py‘)

if __name__ == ‘__main__‘:    run()

print_file，基于print函数，可以使locust打印写入日志文件的方法；使用HttpSession类，需要传入url参数;Run类，需要继承Locust类，而不是HttpLocust类；name=‘/sec_add_event/?data=[md5]‘，将请求分组，便于查看；
