我的请求库有点问题。
比如说我在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,没有抓住异常。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
此外,requests
例外:
import requests.exceptions
dir(requests.exceptions)
另请注意,如果状态不是requests
,默认情况下200
不会引发异常:
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

在python 2.7.5中运行代码:
import requests
try:
response = requests.get('google.com/admin') #Should return 404
except requests.HTTPError, e:
print 'HTTP ERROR %s occured' % e.code
print e
结果:
File "C:\Python27\lib\site-packages\requests\models.py", line 291, in prepare_url
raise MissingSchema("Invalid URL %r: No schema supplied" % url)
requests.exceptions.MissingSchema: Invalid URL u'google.com/admin': No schema supplied
要让您的代码获取此异常,您需要添加:
except (requests.exceptions.MissingSchema) as e:
print 'Missing schema occured. status'
print e
另请注意,它不是缺少的架构,而是缺少方案。
