我很難試圖讓DotNetOpenAuth ctp 4.0工作。這裏的情況: 我有一個資源服務器,就像OAuth2示例中的資源服務器一樣,但是我使用WCF Web Api預覽版6,所以我編寫了一個可擴展性點,負責驗證執行操作請求的客戶機是已經授權這樣做,爲了完成這個,方法ResourceServer.VerifyAccess被調用。這種方法拋出一個空的異常,我還沒有找到原因。DotNetOpenAuth ctp 4.0 ResourceServer.VerifyAccess()方法拋出null異常
這是我寫的我的操作處理程序:
protected override HttpRequestMessage OnHandle(HttpRequestMessage input)
{
var principal = VerifyOAuth2(input);
if(principal == null)
{
throw new HttpResponseException(new HttpResponseMessage
{
StatusCode = HttpStatusCode.Unauthorized,
Content = new StringContent("Invalid Access Token")
});
}
var roles = _authorizationAttribute.Roles.Split(new[] {" "}, StringSplitOptions.RemoveEmptyEntries);
if(!roles.Any(role => principal.IsInRole(role)))
{
throw new HttpResponseException(new HttpResponseMessage
{
StatusCode = HttpStatusCode.Forbidden,
Content = new StringContent("User has not permission to access this resource")
});
}
return input;
}
private static IPrincipal VerifyOAuth2(HttpRequestMessage request)
{
var headers = request.Headers;
var headersCollection = new WebHeaderCollection();
foreach (var header in headers)
{
headersCollection.Add(header.Key, header.Value.ToString());
}
using (var signing = MvcApplication.CreateAuthorizationServerSigningServiceProvider())
{
using (var encrypting = MvcApplication.CreateResourceServerEncryptionServiceProvider())
{
var resourceServer = new ResourceServer(new StandardAccessTokenAnalyzer(signing, encrypting));
IPrincipal result;
var httpRequestInfo = new HttpRequestInfo(request.Method.ToString(), request.RequestUri,
request.RequestUri.AbsoluteUri, headersCollection, request.Content.ReadAsStreamAsync().Result);//Since I dont have an HttpResourceInfo Object I need to build one from my request, using an overloaded method.
var error = resourceServer.VerifyAccess(httpRequestInfo, out result); //here is where the exception is thrown.
// TODO: return the prepared error code.
return error != null ? null : result;
}
}
我不知道如果這個代碼可以幫助,但如果沒有的話,你能告訴我什麼時候這個方法拋出一個空引用例外??也許這會幫助我一點!先謝謝你。
問題..在這裏你正在做的分裂和通過新的[] {」「}你有偶然得到一個錯誤..不使用看到它這樣做的方式 – MethodMan 2012-01-06 21:20:29
沒有,異常在之前拋出,在VerifyOAuth2()方法中 – Daniel 2012-01-06 21:24:10
IPrincipal是來自.net框架的接口。和輸入是HttpRequestMessage的一個目的是從WCF網絡API – Daniel 2012-01-06 21:35:35
