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；

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；
