AttributeError: module ‘asyncio‘ has no attribute ‘WindowsSelectorEventLoopPolicy‘

asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
AttributeError: module 'asyncio' has no attribute 'WindowsSelectorEventLoopPolicy'

这个文件夹

tornado/platform/asyncio.py :

import sys

if sys.platform == 'win32':
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

本人出现场景爬虫抓包windos:

本人装 pip install mitmproxy 完全ok

启动服务

mitmdump

他就报如下错误

File "C:\Users\allve\AppData\Local\Programs\Python\Python36\lib\runpy.py", line 193, in _run_module_as_main
"__main__", mod_spec)

File "C:\Users\allve\AppData\Local\Programs\Python\Python36\lib\runpy.py", line 85, in _run_code exec(code, run_globals) 
File"C:\Users\allve\PycharmProjects\rainbow\venv\Scripts\mitmdump.exe\__main__.py", line 4, in <module>
File "c:\users\allve\pycharmprojects\rainbow\venv\lib\site-packages\mitmproxy\__init__.py", line 8, in <module>

asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
AttributeError: module 'asyncio' has no attribute 'WindowsSelectorEventLoopPolicy'

于是我把上面个那个方法进行使用, 加上去了, 针对我这个应用场景然并卵(此处是个坑,下面会讲到)

解决办法下面文件夹下的代码我给注了.

File "c:\users\allve\pycharmprojects\rainbow\venv\lib\site-packages\mitmproxy\__init__.py", line 8, in <module>

###### 重新启动服务

mitmdump

然后添加证书 手机端 网址 mitm.it 选择对应设备ok抓到相应的包啦

你以为ok啦, 如果要求不高,确实ok啦, 实则太难看了

于是我又想进行抓包可视化页面

mitmweb

又tm 报错这个

File "C:\Users\allve\AppData\Local\Programs\Python\Python36\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "C:\Users\allve\AppData\Local\Programs\Python\Python36\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "C:\Users\allve\PycharmProjects\rainbow\venv\Scripts\mitmweb.exe\__main__.py", line 7, in <module>
  File "c:\users\allve\pycharmprojects\rainbow\venv\lib\site-packages\mitmproxy\tools\_main.py", line 171, in mitmweb
    from mitmproxy.tools import web
  File "c:\users\allve\pycharmprojects\rainbow\venv\lib\site-packages\mitmproxy\tools\web\__init__.py", line 1, in <module>
    from mitmproxy.tools.web import master
  File "c:\users\allve\pycharmprojects\rainbow\venv\lib\site-packages\mitmproxy\tools\web\master.py", line 3, in <module>
    from tornado.platform.asyncio import AsyncIOMainLoop
  File "c:\users\allve\pycharmprojects\rainbow\venv\lib\site-packages\tornado\platform\asyncio.py", line 38, in <module>
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
AttributeError: module 'asyncio' has no attribute 'WindowsSelectorEventLoopPolicy'

于是 这个几个文件加我又看看源码,发现

上面原来加上的代码给注释掉,终于运行啦

如果对你有帮助,点个赞再走呗

主要我太不容易啦
