如何讓OAuth使用DotNetOpenAuth和Evernote？

我想寫使用DotNetOpenAuth庫連接到使用OAuth的的 Evernote的沙盒一個C＃ASP.NET MVC應用程序，但我無法得到它的工作。我的應用沒有問題，直到回調被調用，但是當我嘗試請求在this diagram的步驟10中交換臨時憑證時，它會以401未授權的方式失敗。如何讓OAuth使用DotNetOpenAuth和Evernote？

我的回調看起來是這樣的：在var accessTokenResponse = webConsumer.ProcessUserAuthorization();線，是什麼企圖憑證交流發生

public ActionResult OAuthCallback() 
    { 
     var webConsumer = CreateWebConsumer(); 
     var accessTokenResponse = webConsumer.ProcessUserAuthorization(); 

     if (accessTokenResponse != null) 
     { 
      AccessToken = accessTokenResponse.AccessToken; 
     } 


     return RedirectToAction("Index"); 
    }

的異常。

提琴手顯示以下內容：

調用回調：

GET http://localhost:22297/Home/OAuthCallback?oauth_token=GiddyUpHorsey.13F82BDC264.687474703A2F2F6C6F63616C686F73743A32323239372F486F6D652F4F4175746843616C6C6261636B.CFB67142944B4EB90148DDAFE2120A71&oauth_verifier=93534C2B04F862E57B30D738C3569242 HTTP/1.1

請求令牌交換：

通過webConsumer.ProcessUserAuthorization();觸發。

     </div>

（我去掉了大部分的HTML從響應）

爲什麼會失敗，401授權？

我不確定你是否有這個工作，但我今天早上在Evernote，OpenAuth和C＃上玩弄，並設法讓它工作。我已經把博客文章/庫解釋經驗，並概述瞭如何使用MVC在這裏做到這一點 - http://www.shaunmccarthy.com/evernote-oauth-csharp/ - 它使用AsyncOAuth庫：https://github.com/neuecc/AsyncOAuth

我寫周圍AsyncOAuth的包裝，你會發現這裏很有用：https://github.com/shaunmccarthy/AsyncOAuth.Evernote.Simple

一個帶刺的東西要注意的 - Evernote的端點（/ OAuth的和/OAuth.action）是區分大小寫的

// Download the library from https://github.com/shaunmccarthy/AsyncOAuth.Evernote.Simple 

// Configure the Authorizer with the URL of the Evernote service, 
// your key, and your secret. 
var EvernoteAuthorizer = new EvernoteAuthorizer(
    "https://sandbox.evernote.com", 
    "slyrp-1234", // Not my real id/secret :) 
    "7acafe123456badb123"); 

// First of all, get a request token from Evernote - this causes a 
// webrequest from your server to Evernote. 
// The callBackUrl is the URL you want the user to return to once 
// they validate the app 
var requestToken = EvernoteAuthorizer.GetRequestToken(callBackUrl); 

// Persist this token, as we are going to redirect the user to 
// Evernote to Authorize this app 
Session["RequestToken"] = requestToken; 

// Generate the Evernote URL that we will redirect the user to in 
// order to 
var callForwardUrl = EvernoteAuthorizer.BuildAuthorizeUrl(requestToken); 

// Redirect the user (e.g. MVC) 
return Redirect(callForwardUrl); 

// ... Once the user authroizes the app, they get redirected to callBackUrl 

// where we parse the request parameter oauth_validator and finally get 
// our credentials 
// null = they didn't authorize us 
var credentials = EvernoteAuthorizer.ParseAccessToken(
    Request.QueryString["oauth_verifier"], 
    Session["RequestToken"] as RequestToken); 

// Example of how to use the credential with Evernote SDK 
var noteStoreUrl = EvernoteCredentials.NotebookUrl; 
var noteStoreTransport = new THttpClient(new Uri(noteStoreUrl)); 
var noteStoreProtocol = new TBinaryProtocol(noteStoreTransport); 
var noteStore = new NoteStore.Client(noteStoreProtocol); 
List<Notebook> notebooks = client.listNotebooks(EvernoteCredentials.AuthToken);

我想你的代碼和奇怪的是，我仍然得到401未經授權錯誤。我想知道這個問題是否與我的環境有關。該應用程序必須通過代理服務器與外部世界進行通信。也許這與它有關。 – GiddyUpHorsey

你在哪一步得到401錯誤？用戶看到401還是在GetRequestToken期間發生？ –

它在調用https://sandbox.evernote.com/oauth這一行時發生：'var result = await base.GetAccessToken（OAuthUrl，token，oauth_verifier，null，null）;'AsyncEvernoteoryAuthorizer.cs：Line 115。用戶已在Evernote中授權應用程序，然後發生錯誤。用戶看到有關401 Unauthorized異常的YSOD。 – GiddyUpHorsey
