今天遇到一个奇葩问题,
1.r.request.post(url)
2..print r. status_code
居然第一步就报错了,原因是url不正确,按道理应该可以走到第二步然后输入404的
import requests
try:
requests.get("http://not.a.real.url/really_not")
except requests.exceptions.ConnectionError as e:
pass
>>> e
ConnectionError(MaxRetryError("HTTPConnectionPool(host='not.a.real.url', port=80): Max retries exceeded with url: /really_not (Caused by <class 'socket.gaierror'>: [Errno -2] Name or service not known)",),)
>>> e.args
(MaxRetryError("HTTPConnectionPool(host='not.a.real.url', port=80): Max retries exceeded with url: /really_not (Caused by <class 'socket.gaierror'>: [Errno -2] Name or service not known)",),)
>>> e.args[0]
MaxRetryError("HTTPConnectionPool(host='not.a.real.url', port=80): Max retries exceeded with url: /really_not (Caused by <class 'socket.gaierror'>: [Errno -2] Name or service not known)",)
>>> dir(e.args[0])
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__',
'__getitem__', '__getslice__', '__hash__', '__init__', '__module__', '__new__',
'__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__setstate__', '__sizeof__',
'__str__', '__subclasshook__', '__unicode__', '__weakref__', 'args', 'message', 'pool',
'reason', 'url']
>>> e.args[0].reason
gaierror(-2, 'Name or service not known')
>>> dir(e.args[0].reason)
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__',
'__getitem__', '__getslice__', '__hash__', '__init__', '__module__', '__new__',
'__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__setstate__', '__sizeof__',
'__str__', '__subclasshook__', '__unicode__', '__weakref__', 'args', 'errno', 'filename',
'message', 'strerror']
>>> e.args[0].reason.errno
-2
这样就可以异常设置值
try:
r = login_session.post(self.url, data=self.data,headers=self.headers)
except requests.exceptions.ConnectionError as e:
# print e.args[0].reason #[Errno 11004] getaddrinfo failed
if e.args[0].reason.errno== 11004:
r = 404
final:
return r
得到r,即使不是response类型,也能获取值
getattr(result, ‘status_code’, result)
