Question

我正在尝试使用ASP.net MVC 4内置的OAuth功能连接到QuickBooks。问题（我的意思是，呃挑战）是内置模板（Facebook，谷歌等）都提供两条腿的授权。 QuickBooks使用三个。结果，这真的是在我的屁股上踩了一个泥坑。

好消息是QuickBooks提供了一个MVC 3示例。你可以在这里找到它：

https://ipp.developer.intuit.com/0010_Intuit_Partner_Platform/0025_Intuit_Anywhere/0020_Connect/0010_From_Within_Your_App/Implement_OAuth_in_Your_App

导致我出现问题的最相关代码在这里：

    private String consumerSecret, consumerKey, oauthLink, RequestToken, TokenSecret, oauth_callback_url;

    /// <summary>
    /// Action Result for Index, This flow will create OAuthConsumer Context using Consumer key and Consuler Secret key
    /// obtained when Application is added at intuit workspace. It creates OAuth Session out of OAuthConsumer and Calls 
    /// Intuit Workpsace endpoint for OAuth.
    /// </summary>
    /// <returns>Redirect Result.</returns>
    public RedirectResult Index()
    {
        oauth_callback_url = Request.Url.GetLeftPart(UriPartial.Authority) + ConfigurationManager.AppSettings["oauth_callback_url"];
        consumerKey = ConfigurationManager.AppSettings["consumerKey"];
        consumerSecret = ConfigurationManager.AppSettings["consumerSecret"];
        oauthLink = Constants.OauthEndPoints.IdFedOAuthBaseUrl;
        IToken token = (IToken)Session["requestToken"];
        IOAuthSession session = CreateSession();
        IToken requestToken = session.GetRequestToken();
        Session["requestToken"] = requestToken;
        RequestToken = requestToken.Token;
        TokenSecret = requestToken.TokenSecret;

        oauthLink = Constants.OauthEndPoints.AuthorizeUrl + "?oauth_token=" + RequestToken + "&oauth_callback=" + UriUtility.UrlEncode(oauth_callback_url);
        return Redirect(oauthLink);
    }

    /// <summary>
    /// Gets the Access Token
    /// </summary>
    /// <returns>Returns OAuth Session</returns>
    protected IOAuthSession CreateSession()
    {
        OAuthConsumerContext consumerContext = new OAuthConsumerContext
        {
            ConsumerKey = consumerKey,
            ConsumerSecret = consumerSecret,
            SignatureMethod = SignatureMethod.HmacSha1
        };

        OAuthSession s = new OAuthSession(consumerContext,
                                        Constants.OauthEndPoints.IdFedOAuthBaseUrl + Constants.OauthEndPoints.UrlRequestToken,
                                        oauthLink,
                                        Constants.OauthEndPoints.IdFedOAuthBaseUrl + Constants.OauthEndPoints.UrlAccessToken);

        return s;
    }

由此可以看出，MVC 3示例创建了一个会话并获取了一个请求令牌。我当前的问题是在MVC 4中找到代码位，我可以在其中检索此请求令牌。我认为它在我的AccountController中：

    //
    // POST: /Account/ExternalLogin
    //
    // Go to me first!!!

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult ExternalLogin(string provider, string returnUrl)
    {
        return new ExternalLoginResult(provider, Url.Action("ExternalLoginCallback", new { ReturnUrl = returnUrl }));
    }


    //
    // Go to me second!!!

    internal class ExternalLoginResult : ActionResult
    {
        public ExternalLoginResult(string provider, string returnUrl)
        {
            Provider = provider;
            ReturnUrl = returnUrl;
        }

        public string Provider { get; private set; }
        public string ReturnUrl { get; private set; }

        public override void ExecuteResult(ControllerContext context)
        {
            if(Provider.Equals("Quickbooks Online")){
                // oauthLink = Constants.OauthEndPoints.AuthorizeUrl + "?oauth_token=" + RequestToken + "&oauth_callback=" + UriUtility.UrlEncode(oauth_callback_url);
                // oauthLink    "https://workplace.intuit.com/Connect/Begin?oauth_token=qyprdvh1kZ3dpyobhKfJ54C10xPJPDy0vtwdNCeZmUmbLJdr&oauth_callback=http%3A%2F%2Flocalhost%3A50671%2FOauthResponse" string
                string requestToken = "";  // How do I get this?
                string oauthCallback = context.HttpContext.Request.Url.Scheme + "/OauthResponse";

    //
    // Now do I get a request token?  How?

                string returnUrl = "https://workplace.intuit.com/Connect/Begin" + "?oauth_token=" + requestToken + "&oauth_callback=" + HttpUtility.UrlEncode(oauthCallback);
                OAuthWebSecurity.RequestAuthentication(Provider, returnUrl);
            }
            else{
                OAuthWebSecurity.RequestAuthentication(Provider, ReturnUrl);
            }
        }
    }

但是从这里我迷路了。任何帮助，将不胜感激。我用谷歌搜索了很多，我猜我到目前为止已经投入了40个小时以上的某个地方试图让它发挥作用。

谢谢，将

Intuit Partner Platform目前支持OAuth1.0a。 3段OAuth中的第一站是OAuth请求令牌的采购。

我没有使用过MVC4的OAuthWebSecurity;但是，基于我从doc /源代码中快速收集到的内容，您似乎需要创建一个独特的“QuickBooksClient”（并且，它是开源的吗？）。我会按照LinkedInClient class作为食谱。从IPP docs开始，OAuth端点为：

获取请求令牌：https://oauth.intuit.com/oauth/v1/get_request_token
登录页面：https://appcenter.intuit.com/Connect/Begin
获取访问令牌：https://oauth.intuit.com/oauth/v1/get_access_token

如何用MVC 4实现三脚架OAuth？
