Basic authentication not working with Requests lib

问题:

I'm trying to use basic auth in python

auth = requests.post('http://' + hostname, auth=HTTPBasicAuth(user, password))
request = requests.get('http://' + hostname + '/rest/applications')

Response form auth variable:

<<class 'requests.cookies.RequestsCookieJar'>[<Cookie JSESSIONID=cb10906c6219c07f887dff5312fb for appdynamics/controller>]>
200
CaseInsensitiveDict({'content-encoding': 'gzip', 'x-powered-by': 'JSP/2.2', 'transfer-encoding': 'chunked', 'set-cookie': 'JSESSIONID=cb10906c6219c07f887dff5312fb; Path=/controller; HttpOnly', 'expires': 'Wed, 05 Nov 2014 19:03:37 GMT', 'server': 'nginx/1.1.19', 'connection': 'keep-alive', 'pragma': 'no-cache', 'cache-control': 'max-age=78000', 'date': 'Tue, 04 Nov 2014 21:23:37 GMT', 'content-type': 'text/html;charset=ISO-8859-1'})

But when I try to get data from different location, - I'm got 401 error

<<class 'requests.cookies.RequestsCookieJar'>[]>
401
CaseInsensitiveDict({'content-length': '1073', 'x-powered-by': 'Servlet/3.0 JSP/2.2 (GlassFish Server Open Source Edition 3.1.2.2 Java/Oracle Corporation/1.7)', 'expires': 'Thu, 01 Jan 1970 00:00:00 UTC', 'server': 'nginx/1.1.19', 'connection': 'keep-alive', 'pragma': 'No-cache', 'cache-control': 'no-cache', 'date': 'Tue, 04 Nov 2014 21:23:37 GMT', 'content-type': 'text/html', 'www-authenticate': 'Basic realm="controller_realm"'})

As far as I understand - in second request are not substituted session parameters.

回答1:

You need to use a session object and send the authentication each request. The session will also track cookies for you:

session = requests.Session()
session.auth = (user, password)

auth = session.post('http://' + hostname)
response = session.get('http://' + hostname + '/rest/applications')

回答2:

The example looks a bit different from your code.

>>> from requests.auth import HTTPBasicAuth
>>> requests.get('https://api.github.com/user', auth=HTTPBasicAuth('user', 'pass'))
<Response [200]>

回答3:

import requests

from requests.auth import HTTPBasicAuth
res = requests.post('https://api.github.com/user', verify=False, auth=HTTPBasicAuth('user', 'password'))
print (res)

Note: sometimes, we may get SSL error certificate verify failed, to avoid, we can use verify=False
