Facebook OAuth問題MVC4

Question

令人煩惱的是，我已經嘗試解決這個問題很多小時了，每個答案都不是直接的解決方案：

{
   "error": {
      "message": "Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request",
      "type": "OAuthException",
      "code": 100
   }
}

我一直在撞牆！ 我為此http://pastebin.com/G7ysgbdX使用了Facebook肥皂客戶端

這將使我們能夠（在用戶許可下）整合他們的時間表。 Facebook表示網址不匹配。 我該如何測試？

這在本地有效，但不能在服務器上使用完全相同的代碼，除了http://free-rsvp.com/而不是localhost：53111 /

這是下面的URL。 我看不到任何錯誤！

任何意見，將不勝感激。

這是我的服務器端身份驗證代碼（MVC4項目）的一部分。 您應該查看的部分是如何相同地在“ Authorize”和“ AuthorizeCallback”函數中生成重定向URL，並將其傳遞給facebook客戶端：

[HttpPost]
public ActionResult Authorize(Guid eventId)
{
    var @event = this.eventRepository.Find(eventId);

    var redirectUri = ConfigurationProvider.HostingEndpoint + this.Url.Action("AuthorizeCallback", new { eventCode = @event.Code });

    var service = new FacebookClient();
    var loginUrl = service.GetLoginUrl(new {
        client_id = ConfigurationProvider.FacebookAppId,
        client_secret = ConfigurationProvider.FacebookAppSecret,
        redirect_uri = redirectUri,
        response_type = "code",
        scope = "manage_pages, publish_actions, user_photos, publish_stream" // Add other permissions as needed
    });

    return new RedirectResult(loginUrl.AbsoluteUri, permanent: false);
}

public ActionResult AuthorizeCallback(string code, string eventCode, UserProfile userProfile)
{
    var @event = this.eventRepository.Find(eventCode);

    if (string.IsNullOrWhiteSpace(code) == true)
    {
        // means user clicked "cancel" when he was prompted to authorize the app
        // todo: show some error message? or just redirect back?
        return this.RedirectToAction("Event", "Dashboard", new { eventCode = @event.Code, feature = FeatureType.Update });
    }

    var redirectUri = ConfigurationProvider.HostingEndpoint + this.Url.Action("AuthorizeCallback", new { eventCode = @event.Code });

    var fb = new FacebookClient();
    dynamic result = fb.Post("oauth/access_token", new
    {
        client_id = ConfigurationProvider.FacebookAppId,
        client_secret = ConfigurationProvider.FacebookAppSecret,
        redirect_uri = redirectUri,
        code = code
    });

    var accessToken = result.access_token;

    // update the facebook client with the access token so 
    // we can make requests on behalf of the user
    fb.AccessToken = accessToken;

    // Get the user's information
    dynamic me = fb.Get("me");

    return this.RedirectToAction("Event", "Dashboard", new { eventCode = @event.Code, feature = FeatureType.Update });
}
