request.get()404响应后,requests_HTTPError未被捕获

Question

我的请求库有点问题.

比方说,我在Python中有这样的声明:

try:
   request = requests.get('google.com/admin') #Should return 404

except requests.HTTPError, e:
   print 'HTTP ERROR %s occured' % e.code

由于某种原因,异常没有被捕获.我已经检查了API文档中的请求,但它有点渺茫.是否有人对图书馆有更多经验可以帮助我？

口译员是你的朋友:

import requests
requests.get('google.com/admin')
# MissingSchema: Invalid URL u'google.com/admin': No schema supplied

另外,requests例外:

import requests.exceptions
dir(requests.exceptions)

另请注意,requests如果status不是,则默认情况下不会引发异常200:

In [9]: requests.get('https://google.com/admin')
Out[9]: <Response [503]>

有raise_for_status()方法可以做到:

In [10]: resp = requests.get('https://google.com/admin')

In [11]: resp
Out[11]: <Response [503]>

In [12]: resp.raise_for_status()
  ...
HTTPError: 503 Server Error: Service Unavailable
