Annoyingly I have been trying to solve this issue for many hours, every answer is no direct solution:

{
   "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
   }
}

I have been banging my head against the wall!. I am using the facebook soap client for this http://pastebin.com/G7ysgbdX

This will allow us to integrate (with the user's permission) their timeline. Facebook is saying the URL's do not match. How do I test this?

This works locally but not on the server with the exact same code except http://free-rsvp.com/ instead of localhost:53111/

This is the below URL. I cannot see anything wrong!

Any advice would be appreciated.

这是我的一段服务器端身份验证代码（MVC4 项目）。您应该查看的部分是如何生成重定向 URL - 同样 - 在“Authorize”和“AuthorizeCallback”函数中 - 并传递给 facebook 客户端：

[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 });
}
