使用itchat过程碰到urllib3的异常

在用itchat做微信防撤回的时候，出现了这么个异常，而且没有找到对应的代码，好像是urllib3的库的原因，不能处理0这个HTTP响应码。难道我要去改urllib3？

然后找到这个
https://stackoverflow.com/questions/27619258/httplib-badstatusline
说是捕获一下异常，然后pass，但是我连这个异常的代码在哪我都不知道。
然后看到之前itchat的issue里提的问题，也出现过这种情况。
https://github.com/littlecodersh/ItChat/issues/353
https://github.com/littlecodersh/ItChat/issues/424
但是貌似都没有解决。
那就老老实实看看代码吧。根据异常栈找到raise出这个异常的地方：在我电脑上是/usr/local/Cellar/python/3.6.5/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py

 257     def _read_status(self):
 258         line = str(self.fp.readline(_MAXLINE + 1), "iso-8859-1")
 259         if len(line) > _MAXLINE:
 260             raise LineTooLong("status line")
 261         if self.debuglevel > 0:
 262             print("reply:", repr(line))
 263         if not line:
 264             # Presumably, the server closed the connection before
 265             # sending a valid response.
 266             raise RemoteDisconnected("Remote end closed connection without"
 267                                      " response")
 268         try:
 269             version, status, reason = line.split(None, 2)
 270         except ValueError:
 271             try:
 272                 version, status = line.split(None, 1)
 273                 reason = ""
 274             except ValueError:
 275                 # empty version will cause next test to fail.
 276                 version = ""
 277         if not version.startswith("HTTP/"):
 278             self._close_conn()
 279             raise BadStatusLine(line)
 280
 281         # The status code is a three-digit number
 282         try:
 283             status = int(status)
 284             if status < 100 or status > 999:
 285                 raise BadStatusLine(line)
 286         except ValueError:
 287             raise BadStatusLine(line)
 288         return version, status, reason

从#284可以看出，状态码必须是[100,999]之间的三位数，而我们这里的状态码是0，所以抛出了异常。
