我正在尝试使用 ASP .NET MVC 4 的内置 OAuth 功能来连接到 QuickBooks。问题（我的意思是，呃挑战）是内置模板（facebook、google 等）都提供两条腿授权。QuickBooks 使用三个。结果，这真的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

引起我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;
    }

从那里，您可以看到 MVC 3 示例创建了一个会话并获取了一个请求令牌。我的直接问题是在 MVC 4 中找到可以检索此请求令牌的代码位。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，我猜到目前为止我已经投入了超过 40 小时的时间来尝试让它发挥作用。

谢谢，威尔

Intuit 合作伙伴平台目前支持 OAuth1.0a。3-legged OAuth 的第一站是获取 OAuth 请求令牌。

我没有使用 MVC4 的 OAuthWebSecurity；但是，根据我从文档/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，开源它？）。我会按照LinkedInClient 类作为食谱。在IPP docs中，OAuth 端点是：

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
