问题描述：
python3.7.8+locust1.0，性能测试运行过程中接口测试请求为空。运行测试脚本报错如下：
报错信息1：
Exception: No tasks defined. use the @task decorator or set the tasks property of the User将从locust中导入的HttpLocust改为HttpUser，即from locust import HttpLocust改为from locust import HttpUser,将脚本中引用的所有HttpLocust都改为HttpUser
解决方法：
将从locust中导入的HttpLocust改为HttpUser，即from locust import HttpLocust改为from locust import HttpUser,将脚本中引用的所有HttpLocust都改为HttpUser.
报错信息2：
C:\Python3.7.8\python.exe C:/Users/Administrator/Desktop/api_test/locust/restful_api_locust.py
C:\Python3.7.8\lib\site-packages\locust\util\deprecation.py:14: DeprecationWarning: Usage of User.task_set is deprecated since version 1.0. Set the tasks attribute instead (tasks = [UserBehavior])
"(tasks = [%s])" % task_set.__name__, DeprecationWarning)
解决方法：
将class WebsiteUser(HttpUser): 中的 task_set = UserBehavior 修改为 tasks = [UserBehavior]
