Question

我正在调用API并收到以下超时错误：

socket.timeout The read operation timed out

从

追溯

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

如何从回溯顶部捕获此错误？

Answer 1

这是一个重复的问题，但正确的方法是使用

捕获socket.timeout

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

错误说明了显式抛出的异常，您可以依赖它。即使调用方法是ssl lib，错误似乎与实际的套接字连接有关。

谷歌搜索导致我https://community.home-assistant.io/t/difficulty-catching-an-exception/12955/6

似乎SSL在超时时抛出ssl.SSLError。你可以尝试类似的东西：

import ssl

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

捕获＆＃34; socket.timeout读取操作超时＆＃34;在python中
