使用httplib2处理身份验证和代理服务器 [英] Handling authentication and proxy servers with httplib2
问题描述
我正在尝试测试与Nexus服务器的交互，该服务器需要对我要使用的操作进行身份验证，但是我还需要处理内部代理服务器.
I'm attempting to test interactions with a Nexus server that requires authentication for the operations I intend to use, but I also need to handle an internal proxy server.
基于我的(有限的)理解，我可以向启动器添加多个处理程序.但是我仍然收到401响应.我检查了用户名和密码是否有效.我不确定是否需要cookie来执行此操作，以及是否包含cookie. 有什么建议吗?
Based on my (limited) understanding I can add multiple handlers to the opener. However I'm still getting a 401 response. I've checked the username and password are valid. I'm not certain if cookies are required to do this and if so how they'd be included. Any suggestions?
baseUrl = 'server:8070/nexus-webapp-1.3.3/service/local'
params = {"[key]":"[value]"}
data = urllib.urlencode(params)
# create a password manager
password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()
# Add the username and password as supplied
password_mgr.add_password(None, baseUrl, username, password)
handler = urllib2.HTTPBasicAuthHandler(password_mgr)
proxy_support = urllib2.ProxyHandler({})
# create "opener" (OpenerDirector instance)
opener = urllib2.build_opener(proxy_support, handler)
urllib2.install_opener(opener)
txheaders = {'User-agent' : 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'}
req = Request(protocol+url, data, txheaders)
handle = urlopen(req)
这是结果URLError的标题字段:
This is the resulting URLError's headers field:
>HTTPMessage: Server: Apache-Coyote/1.1
Set-Cookie: JSESSIONID=B4BD05C9582F7B27495CBB675A339724; Path=/nexus-webapp-1.3.3

Update It seems Nexus implement a custom version of Restlet's AuthenticationHelper. Thanks to Alex I knew what to look for.
推荐答案
您能显示所获得的401响应的完整标题吗?也许这不是基本的身份验证请求，可能是代理服务器需要自己的身份验证-很难看到没有所述标头的信息！
Can you show the full headers of the 401 response you're getting? Maybe it's not a basic auth request, maybe it's the proxy wanting its own authentication -- it's hard to guess without seeing said headers!
编辑:感谢您显示标题(我将其重新格式化为代码"，否则无法读取).
Edit: thanks for showing the headers (I reformatted them as "code" else they were unreadable).
正如我所怀疑的那样，它不需要基本"，而需要其他一些(Nexus专有...?)"NxBASIC"身份验证协议-我从没听说过(我对此一无所知Nexus)，我想您都不会使用基本身份验证处理程序(即使NxBASIC某种程度上接受了普通的基本身份验证，该处理程序仅知道它是一个不同的协议，也不会提供这种身份验证).
As I suspected, it doesn't want "Basic", it wants some other (Nexus proprietary...?) "NxBASIC" authentication protocol -- I've never heard about it (I don't know anything about Nexus) and I imagine neither has the basic authentication handler you're using (even if NxBASIC somehow accepted plain Basic authentication, the handler, knowing only that it's a different protocol, would not offer such authentication).
因此，首先，您需要准确研究NxBASIC的含义，为此，我怀疑带有正确标签的SO问题可能会有所帮助.然后，根据您所学的知识，出现了一个有趣的问题，即为其定义处理程序...！-(
So, first you need to research exactly what that NxBASIC thing is, and for that I suspect a SO question with the right tags might help. Then, depending on what you learn, comes the interesting issue of defining a handler for it...!-(
