AJAX调用不会触发操作方法当装饰用CanvasAuthorize

问题描述

我想通过通过我的FB应用在墙壁上张贴他们在Facebook上分享项目。我设置的一切在客户端和服务器端，以及（ASP.NET MVC3），但我注意到，当ActionMethod装饰与 CanvasAuthorize 属性，该方法不没有得到所有触发。那么，有什么我可以做什么？

I am trying to share items on Facebook by posting them on the wall via my FB app. I setup everything on the client side and the server side as well (ASP.NET MVC3), but I noticed that when the ActionMethod is decorated with the CanvasAuthorize attribute, the method does not get triggered at all. So is there anything I could do?

P.S：我通过AJAX调用检查发布的​​数据，一切都似乎在为此罚款。此外，如果我评论了 [CanvasAuthorize] 线，该方法被触发，PARAMS无一不精，除非我得到的 fb.Post （）呼叫时，报告说，没有任何的access_token这是有道理的。

P.S: I checked the posted data by the AJAX call and everything seemed fine on that end. Moreover, if I comment the [CanvasAuthorize] line, the method gets triggered and the params are all fine, except when I get to the fb.Post() call, it complains that there is no access_token which makes sense.

    //[CanvasAuthorize(Permissions = "publish_stream")]
    public ActionResult PostItem(string message, string link, string picture, string name)
    {
        var fb = new FacebookWebClient();
        var postArgs = new Dictionary<string, string>();
        postArgs["message"] = message;
        postArgs["link"] = link;
        postArgs["picture"] = picture;
        postArgs["name"] = name;
        fb.Post("/me/feed", postArgs);
        return Json(new {result = "success"}, JsonRequestBehavior.AllowGet);
    }

任何想法？

更新：

下面是后续：Passing用AJAX调用的ActionMethod饰有CanvasAuthorize 沿signed_request

Here's a follow-up: Passing the signed_request along with the AJAX call to an ActionMethod decorated with CanvasAuthorize

推荐答案

使用，你通过你的Ajax调用隐藏字段。

Use a hidden field which you pass with your ajax call.

您可以自己或使用实现这个：

You can implement this by yourself or use:

<%: Html.FacebookSignedRequest() %>
