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 before265             # 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)280281         # The status code is a three-digit number282         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。
