Python - 脚本中使用了bs4.BeautifulSoup方法，执行时提示如下警告

#问题现象：

脚本中使用了bs4.BeautifulSoup方法，执行时提示如下警告：

D:\Program Files\python3\pyworks\getProxy.py:15: UserWarning: No parser was explicitly specified, so I'm using the best available HTML parser for this system ("html.parser"). This usually isn't a problem, but if you run this code on another system, or in a different virtual environment, it may use a different parser and behave differently.

 

The code that caused this warning is on line 15 of the file D:\Program Files\python3\pyworks\getProxy.py. To get rid of this warning, pass the additional argument 'features="html.parser"' to the BeautifulSoup constructor.

 

  proxyList = bs4.BeautifulSoup(proxyHTML.read())

 

#解决方法：

使用时添加html.parser参数

proxyList = bs4.BeautifulSoup(proxyHTML.read(),"html.parser")
