Python请求中的SSLError (读取操作超时)
Python请求中的SSLError (读取操作超时)
提问于 2014-06-13 09:09:20
我有一个python API脚本，尽管我使用的是try/except，但我的脚本有时会在该行终止。代码如下：
try:
r = requests.post(URL, data=params, headers=headers, timeout=self.request_timeout)
try:
response = r.json()
except Exception, e:
message = "ERROR_0104! Unexpected error occured. The error is: "
message += str(e)
print message
aux_func.write_log(message)
return 'Switch'
except requests.exceptions.RequestException:
print "Exception occurred on 'API requests post' procedure."
counter += 1
continue
...上述代码的第二行出现错误。这是错误：
r = requests.post(URL, data=params, headers=headers, timeout=self.request_timeout)
File "/usr/local/lib/python2.7/dist-packages/requests/api.py", line 88, in post
return request('post', url, data=data, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/requests/api.py", line 44, in request
return session.request(method=method, url=url, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 383, in request
resp = self.send(prep, **send_kwargs)
File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 486, in send
r = adapter.send(request, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/requests/adapters.py", line 394, in send
r.content
File "/usr/local/lib/python2.7/dist-packages/requests/models.py", line 679, in content
self._content = bytes().join(self.iter_content(CONTENT_CHUNK_SIZE)) or bytes()
File "/usr/local/lib/python2.7/dist-packages/requests/models.py", line 616, in generate
decode_content=True):
File "/usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/response.py", line 236, in stream
data = self.read(amt=amt, decode_content=decode_content)
File "/usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/response.py", line 183, in read
data = self._fp.read(amt)
File "/usr/lib/python2.7/httplib.py", line 543, in read
return self._read_chunked(amt)
File "/usr/lib/python2.7/httplib.py", line 585, in _read_chunked
line = self.fp.readline(_MAXLINE + 1)
File "/usr/lib/python2.7/socket.py", line 476, in readline
data = self._sock.recv(self._rbufsize)
File "/usr/lib/python2.7/ssl.py", line 305, in recv
return self.read(buflen)
File "/usr/lib/python2.7/ssl.py", line 224, in read
return self._sslobj.read(len)
ssl.SSLError: The read operation timed out我认为是Requests模块中的某个东西导致了这种情况，但我不知道是什么原因。

except Exception, e不适用于>= Python3您必须将其设置为except Exception as e

我看到这里有一些关于解决方案的混乱，因为缺乏足够的细节。我将评论中的答案发布到了顶部，但是评论部分的格式不是很好，我将在这里发布一个格式正确的答案。
问题是，正如Veedrac提到的那样，我没有捕捉到我在问题中发布的代码中所有可能的异常。我的代码只捕获"requests.exceptions.RequestException"，任何其他异常都会导致代码突然退出。
相反，我将重写代码，如下所示：
try:
r = requests.post(URL, data=params, headers=headers, timeout=self.request_timeout)
try:
response = r.json()
except Exception, e:
message = "ERROR_0104! Unexpected error occured. The error is: "
message += str(e)
print message
aux_func.write_log(message)
return 'Switch'
except requests.exceptions.RequestException:
print "Exception occurred on 'API requests post' procedure."
counter += 1
continue
except Exception, e:
print "Exception {0} occurred".format(e)
continue我所做的就是在最后添加一个额外的通用异常捕获器，它将捕获所有其他未解释的异常。
我希望这能帮到你。
谢谢。
