在Python中捕获“ socket.timeout读取操作超时”

Question

我正在调用API，并收到以下超时错误：

socket.timeout The read operation timed out

追溯到

File "/Users/someuser/anaconda/envs/python3/lib/python3.5/http/client.py", line 1198, in getresponse
    response.begin()
  File "/Users/someuser/anaconda/envs/python3/lib/python3.5/http/client.py", line 297, in begin
    version, status, reason = self._read_status()
  File "/Users/someuser/anaconda/envs/python3/lib/python3.5/http/client.py", line 258, in _read_status
    line = str(self.fp.readline(_MAXLINE + 1), "iso-8859-1")
  File "/Users/someuser/anaconda/envs/python3/lib/python3.5/socket.py", line 576, in readinto
    return self._sock.recv_into(b)
  File "/Users/someuser/anaconda/envs/python3/lib/python3.5/ssl.py", line 937, in recv_into
    return self.read(nbytes, buffer)
  File "/Users/someuser/anaconda/envs/python3/lib/python3.5/ssl.py", line 799, in read
    return self._sslobj.read(len, buffer)
  File "/Users/someuser/anaconda/envs/python3/lib/python3.5/ssl.py", line 583, in read
    v = self._sslobj.read(len, buffer)
socket.timeout The read operation timed out

如何从回溯的顶部捕获此错误？

Answer 1

这是一个重复的问题，但是正确的方法是socket.timeout使用

import socket
try:
    ...
except socket.timeout:
    ...

该错误指出了显式抛出的异常，您可以依赖它。尽管调用方法是 ssl lib，但错误似乎与实际的套接字连接有关。

谷歌搜索找到了我https://community.home-assistant.io/t/difficulty-having-an-exception/12955/6

似乎 SSLssl.SSLError在超时时会抛出异常。你可以尝试这样的事情：

import ssl

def getresponse():
     ...
     try:
          response.begin
     except ssl.SSLError as err:
          handle_error(err)
