问题
I am in the process of identifying a framework for building a local OAuth (2.0) Provider with a good client library (there aren’t many), at a glance DotNetOpenAuth seems to be ideal and I got excited and wanted to try out the samples.
I spent few days fiddling with the sample and the source itself still I couldn’t figure out a way to get the OAuth2\AuthorizationServer sample working. Sample works fine for all other external providers. I went through numerous posts to figure out ideal setup, inputs, settings to get pass initial login screen but I had no luck.
Can someone please share the initial steps to be followed to get the OAuth2\AuthorizationServer sample up and running. Including the database setup. I tried stepping through the code but lost it.
Appreciate your time. I am very happy to document the steps if I can understand them clearly. I think the framework is excellent but documentation is lacking. Thanks again!
This is the error I am getting,
DotNetOpenAuth.Messaging.ProtocolException: No OpenID endpoint found. ---> System.InvalidOperationException: Sequence contains no elements
I’ve used relying party URI as inputs, http:// localhost:59722 / http:// localhost:59722 /SampleWcf2.aspx
And the full stack trace,

回答1:
It sounds like you're confusing OAuth 2.0 authorization servers with OpenID 2.0 Providers. They are totally different. When "logging in" to the authorization server sample, which appears to be the failure point in your original question, you need to enter a valid OpenID. The URLs you were trying appear to be URLs to the OAuth 2.0 client sample, which isn't an OpenID.
You should log into the authorization server using identifiers like those supplied by the OpenIdProvider sample, or (most easily) just use "yahoo.com" if you have a Yahoo account or "tinyurl.com/googop" to log in using Google.
回答2:
Unless I'm mistaken (which isn't entirely unlikely) the AuthorizationServer sample pretty much acts as a gateway which validates OAuth requests by authorizing the user against an OpenID provider. Instead of putting the relying party's URL in, you might try putting in an OpenID provider URL. (even for testing, you should be fine using any of the public providers you may have an account with)
