我使用 VS2012RC 创建了一个 mvc4 webapi 项目。我试图在我的项目中实现两条腿的 Oauth 2。我按照教程“http://community.codesmithtools.com/CodeSmith_Community/b/tdupont/archive/2011/03/18/oauth-2-0-for-mvc-two-legged-implementation.aspx”，即使它适用于 mvc，我正在为 web api 实现它。但不工作
我为我的客户端创建了一个 html 页面。当 html 页面加载时，它会执行一个旨在返回“访问令牌”的 ajax 函数。
<script type="text/javascript">
$(document).ready(function () {
var url = 'http://localhost:9792/api/Login';
$.get(url, function(data) {
alert(data);
}, "jsonp");
});
</script>
服务器端代码是，
[NoCache]
public class LoginController : ApiController
{
public LoginModelOAuth GetLogin()
{
var response = OAuthServiceBase.Instance.RequestToken();
LoginModelOAuth lmo = new LoginModelOAuth();
lmo.RequestToken = response.RequestToken;
return lmo;
}
}
RequestToken()方法看起来像，
public override OAuthResponse RequestToken()
{
var token = Guid.NewGuid().ToString("N");
var expire = DateTime.Now.AddMinutes(5);
RequestTokens.Add(token, expire);
return new OAuthResponse
{
Expires = (int)expire.Subtract(DateTime.Now).TotalSeconds,
RequestToken = token,
RequireSsl = false,
Success = true
};
}
LoginModelOAuth模型看起来像，
public class LoginModelOAuth
{
public string RequestToken { get; set; }
public string ErrorMessage { get; set; }
public string ReturnUrl { get; set; }
}
当我执行客户端代码时，我收到以下错误
"500 Internal Server Error"
所以我调试了服务器端代码，在服务器端我得到了一个与此代码相对应的错误
“var response = OAuthServiceBase.Instance.RequestToken();” , 错误是
NullReferenceException was unhandled by user code
"Object reference not set to an instance of an object."
我的 webconfig 文件看起来像，
<configuration>
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

它适用于web api吗？
如果没有，请向我推荐任何有用的教程。
谢谢。
