如何在 python Requests 库中使用基本的 HTTP 身份验证? [英] How do I use basic HTTP authentication with the python Requests library?

问题描述

我正在尝试在 python 中使用基本的 HTTP 身份验证.我正在使用 Requests 库:

I'm trying to use basic HTTP authentication in python. I am using the Requests library:

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

回复表单 auth 变量:

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'})

但是当我尝试从不同位置获取数据时，出现 401 错误

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"'})

据我所知 - 在第二个请求中没有替换会话参数.

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

推荐答案

您需要使用 会话对象 并发送认证每个请求.该会话还将为您跟踪 cookie:

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')
