我真的在试图理解OpenID和OAuth之间的区别?也许它们是完全不同的两件事?


当前回答

我相信重新审视这个问题是有意义的,正如评论中所指出的,OpenID Connect的引入可能带来更多的困惑。

OpenID Connect是一种类似于OpenID 1.0/2.0的身份验证协议,但它实际上构建在OAuth 2.0之上,因此您将获得授权功能和身份验证功能。这两者之间的区别在这篇(相对较新的,但很重要的)文章中有很好的详细解释:http://oauth.net/articles/authentication/

如果您的用户只是想登录Facebook或Twitter,请使用OAuth。如果您的用户是运行自己的OpenID提供者的用户,请使用OpenID,因为他们“不希望其他人拥有自己的身份”。

很多人仍然访问这个网站,这里有一个非常简单的图表来解释它

礼貌维基百科

OpenID证明你是谁。

OAuth授予对授权方提供的特性的访问权。

OAuth在授权之上构建身份验证:用户将对其身份的访问委托给应用程序,然后应用程序成为身份API的消费者,从而找出是谁首先授权了客户端http://oauth.net/articles/authentication/

更多的是对问题的延伸而不是答案,但它可能会为上面伟大的技术答案增加一些视角。我是一个在很多领域都很有经验的程序员,但是在网页编程方面完全是个新手。现在尝试使用Zend框架构建一个基于web的应用程序。

Definitely will implement an application-specific basic username/password authentication interface, but recognize that for a growing number of users the thought of yet another username and password is a deterrent. While not exactly social networking, I know that a very large percentage of the application's potential users already have facebook or twitter accounts. The application doesn't really want or need to access information about the user's account from those sites, it just wants to offer the convenience of not requiring the user to set up new account credentials if they don't want to. From a functionality point of view, that would seem a poster child for OpenID. But it seems that neither facebook nor twitter are OpenID providers as such, though they do support OAuth authentication to access their user's data.

在我读过的所有关于这两者及其区别的文章中,直到我看到上面Karl Anderson的观察,“OAuth可以用于身份验证,这可以被认为是一种无操作授权”,我才看到任何明确的确认OAuth足以满足我想要做的事情。

In fact, when I went to post this "answer", not being a member at the time, I looked long and hard at the bottom of this page at the options for identifying myself. The option for using an OpenID login or obtaining one if I didn't have one, but nothing about twitter or facebook, seemed to suggest that OAuth wasn't adequate for the job. But then I opened another window and looked for the general signup process for stackoverflow - and lo and behold there's a slew of 3rd-party authentication options including facebook and twitter. In the end I decided to use my google id (which is an OpenID) for exactly the reason that I didn't want to grant stackoverflow access to my friends list and anything else facebook likes to share about its users - but at least it's a proof point that OAuth is adequate for the use I had in mind.

It would really be great if someone could either post info or pointers to info about supporting this kind of multiple 3rd-part authorization setup, and how you deal with users that revoke authorization or lose access to their 3rd party site. I also get the impression that my username here identifies a unique stackoverflow account that I could access with basic authentication if I wanted to set it up, and also access this same account through other 3rd-party authenticators (e.g. so that I would be considered logged in to stackoverflow if I was logged in to any of google, facebook, or twitter...). Since this site is doing it, somebody here probably has some pretty good insight on the subject. :-)

很抱歉这篇文章写了这么长时间,而且更多的是一个问题而不是一个答案——但是Karl的评论似乎是在OAuth和OpenID上大量的帖子中最合适的地方。如果我没有找到更好的地方,我提前道歉,我确实试过了。
