通过OAuth的Evernote AuthToken

Question

我以前使用过OAuth (使用Twitter和PHP)，它很简单。我正在尝试让OAuth与EverNote API示例https://github.com/evernote/evernote-sdk-csharp一起工作(因为，正如他们所说的，“真正的应用程序使用OAuth对Evernote进行身份验证”)。我看了这些：

Simple C# Evernote API OAuth example or guide?

https://github.com/sethhitch/csharp-oauth-sample

http://blog.stevienova.com/2008/04/19/oauth-getting-started-with-oauth-in-c-net/

但是，我还是不知道该怎么做。这是我的代码：

    // Real applications authenticate with Evernote using OAuth, but for the
    // purpose of exploring the API, you can get a developer token that allows
    // you to access your own Evernote account. To get a developer token, visit 
    // https://sandbox.evernote.com/api/DeveloperToken.action
    String authToken = "myAuthCode";

    if (authToken == "your developer token") {
      Console.WriteLine("Please fill in your developer token");
      Console.WriteLine("To get a developer token, visit https://sandbox.evernote.com/api/DeveloperToken.action");
      return;
    }

如何添加OAuth以获取我的authToken

谢谢。

要添加的简单代码是：

EvernoteOAuth oauth = new EvernoteOAuth(EvernoteOAuth.HostService.Sandbox, myConsumerKey, myConsumerSecret);
        string errResponse = oauth.Authorize();
        if (errResponse.Length == 0)
        {
            Console.WriteLine(string.Format("Token: {0}\r\n\r\nExpires: {1}\r\n\r\nNoteStoreUrl: {2}\r\n\r\nUserId: {3}\r\n\r\nWebApiUrlPrefix: {4}", oauth.Token, oauth.Expires, oauth.NoteStoreUrl, oauth.UserId, oauth.WebApiUrlPrefix));
        }
        else
        {
            Console.WriteLine("A problem has occurred in attempting to authorize the use of your Evernote account: " + errResponse);
        }

您将需要使用此程序集：

using EvernoteOAuthNet;

检查这个样例项目：http://discussion.evernote.com/topic/30584-here-is-a-net-oauth-assembly/。我认为这将帮助你理解oauth是如何工作的。

对于任何想要在MVC中运行它的人来说，我今天早上尝试了Evernote，OpenAuth和C#，并设法让它们都运行起来。我在这里整理了一篇博客文章/库，解释了这种体验并概述了如何使用MVC - http://www.shaunmccarthy.com/evernote-oauth-csharp/ -它使用AsyncOAuth库：https://github.com/neuecc/AsyncOAuth

我为AsyncOAuth编写了一个包装器，在这里您可能会发现它很有用：https://github.com/shaunmccarthy/AsyncOAuth.Evernote.Simple

需要注意的一件棘手的事情是，Evernote端点(/oauth和/OAuth.action)区分大小写

// 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);
