的WebAPI的OAuth UseOAuthBearerAuthentication给出＆QUOT;序列包含多个元素＆QUOT;错误 [英] WebApi OAuth UseOAuthBearerAuthentication gives "Sequence contains more than one element" error

问题描述

我由这些线配置我的WebAPI的OAuth 2.0：

I configured my WebApi OAuth 2.0 by these lines:

    app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions
    {
        Provider = new OAuthBearerAuthenticationProvider(),
    });

    app.UseOAuthBearerTokens(OAuthOptions);

但它给了我下面的错误在每个请求：

But it gives me the following error at each request :

Message : An error has occurred.
ExceptionMessage : Sequence contains more than one element
ExceptionType : System.InvalidOperationException
StackTrace :    at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable`1 source)

   at System.Web.Http.Dispatcher.HttpControllerDispatcher.d__1.MoveNext()

我的 OAuthOptions 是：

    OAuthOptions = new OAuthAuthorizationServerOptions
    {
        TokenEndpointPath = new PathString("/Token"),
        Provider = new ApplicationOAuthProvider(PublicClientId, UserManagerFactory),
        AuthorizeEndpointPath = new PathString("/Account/ExternalLogin"),
        AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
        AllowInsecureHttp = true,
    };
}

如果我评论的 UseOAuthBearerAuthentication 一切OK！我没有定制OAuthBearerAuthenticationProvider但我直接使用它，但它为什么给我的错误？

If I comment UseOAuthBearerAuthentication everything is ok! I didn't customize OAuthBearerAuthenticationProvider yet and I use it directly but why does it give me error?

推荐答案

这应该是一个错误！使用

It should be a bug! Use

app.UseOAuthAuthorizationServer（OAuthOptions）;

而不是

app.UseOAuthBearerTokens（OAuthOptions）;
