Node.js NTLM HTTP验证，如何处理3种类型 [英] Node.js NTLM HTTP Authentication, how to handle the the 3 types

问题描述

好的，对不起，如果这是一个愚蠢的问题，但我试图让NTLM身份验证工作与Node.js.我一直在阅读（ http://davenport.sourceforge.net/ntlm.html#theNtlmMessageHeaderLayout ）。我发送标题并获得Base64认证头。

Alright, sorry if this is a stupid question, but I'm trying to get NTLM Authentication working w/ Node.js. I've been reading this ( http://davenport.sourceforge.net/ntlm.html#theNtlmMessageHeaderLayout ). I send the header and get a Base64 authentication header.

我尝试通过使用base64编码的新缓冲区将其从Base64转换为UTF8，然后调用 toString（'utf8'）返回一个字符串，如

I tried converting it from Base64 to UTF8 by making a new Buffer with base64 encoding and then calling toString('utf8') which returns a string something like

NTLMSSP\\\\\\
\ u0000\\\\\\\\\�\b�\\\

这是我需要帮助的地方。我明白NTLMSSP\\\是空终止的签名，但是其余的是应该是/ em>来表示，但对我来说这只是垃圾。它是unicode字符，但我应该如何获得实际的数据？我可能会错误地转换，这可能会增加我的烦恼，但我希望有人能够帮助。

This is where I need help. I understand the NTLMSSP\u0000 is the null terminated signature, but and what the rest is supposed to indicate, but to me it's just garbage. It's unicode characters, but how am I supposed to get actual data out of that? I may be converting it incorrectly, which may be adding to my troubles, but I'm hoping someone can help.

有看看 http://www.innovation.ch/personal/ronald/ntlm.html
你收到的是一个Type-2消息。这些页面以非常实用的方式解释。您必须提取服务器挑战（nonce）和服务器标志。

Have a look at http://www.innovation.ch/personal/ronald/ntlm.html What you receive is a Type-2 Message. The pages explains it in a very practical way. You have to extract the server challenge (nonce) and the server flags.

我刚刚为node.js实现了一个模块： https://github.com/SamDecrock/node-http-ntlm

I just implemented a module for node.js to do just that: https://github.com/SamDecrock/node-http-ntlm
