问题描述
我有这段代码可以很好地在locust.io部署的服务器上第一次运行，但是当我开始/停止进行新的运行时，关于列表，我会遇到多个错误。你们可以帮我骑自行车吗？
from locust import HttpUser,task,between,SequentialTaskSet,events
import uuid
import json
import csv
import logging,sys,random,os
with open('somecsv.csv','r') as f:
reader = csv.reader(f)
user= list(reader)
#print(user)
class somethingclass(SequentialTaskSet):
def on_start(self):
if len(user) > 0:
self.id= str(user.pop()).strip("][''")
@task
def someting(self):
do something with self.id request
@task
def someting2(self):
do something with self.id request
class Main(HttpUser):
wait_time = between(5,10)
tasks = [somethingclass]
def _init_(self,*args,**kwargs):
super(Main,self)._init_(*args,**kwargs)
错误是：
[2020-08-18 23：06：50,899] PC / ERROR / locust.user.task：“ somethingclass”对象没有属性“ id” 追溯（最近一次通话）： 运行中的文件“ c：\ windows \ system32 \ src \ locust \ locust \ user \ task.py”，第284行 self.execute_next_task（） 在execute_next_task中，文件“ c：\ windows \ system32 \ src \ locust \ locust \ user \ task.py”，第309行 self.execute_task（self._task_queue.pop（0）） 在execute_task中的文件“ c：\ windows \ system32 \ src \ locust \ locust \ user \ task.py”，第321行 任务（个体） 文件“ C：\ Users \ user \ Desktop \ Work \ Chipico Chip Transfer \ chiptransfer_load.py”，第44行 “ uuid”：'％s'％self.id， AttributeError：“ somethingclass”对象没有属性“ id”
解决方法
您可以使用test_start and test_stop events重置user数据。
from locust import User,task,constant,TaskSet,events
from logging import getLogger
import uuid
logger = getLogger("test")
user = []
@events.test_start.add_listener
def start_something(**kwargs):
logger.info("Starting test...")
user.append(uuid.uuid4())
class somethingclass(TaskSet):
@task
def do_something(self):
logger.info(f"User: {user}")
class Main(User):
wait_time = constant(2)
tasks = [somethingclass]
这为我提供了以下输出，其中包括多次停止和开始测试。

从蝗虫导入用户，任务，常量，任务集，事件 从日志导入getLogger 导入uuid
logger = getLogger（“ test”） 用户= []
@ events.test_start.add_listener def start_something（** kwargs）： logger.info（“正在开始测试...”） user.append（uuid.uuid4（））
class somethingclass（TaskSet）： @任务 def do_something（自己）： logger.info（f“用户：{user}”）
Class Main（User）： wait_time =常量（2） 任务= [somethingclass]
是正确答案
