使用 Facebook C# SDK 在 Facebook 页面上作为页面而不是管理员用户发布

Question

我正在开发使用 Facebook C# SDK 管理 Facebook 上的粉丝页面的 C# 应用程序。我遇到了两个问题，一个与在墙上发布消息有关，另一个与在粉丝页面上创建事件有关。

是否可以在粉丝页面墙上发布消息作为粉丝页面而不是管理员用户？

我可以使用 Facebook C# SDK 以编程方式在粉丝页面（不是管理员，而是作为粉丝页面）上创建事件吗？

我浏览了其他 SDK 的一些其他教程，例如 Facebook PHP SDK。 PHP SDK 允许将事件创建为粉丝页面，但在 C# SDK 的情况下，创建事件不会给出任何结果。

好的，我刚刚遇到了同样的事情。出于我的目的，我授权一个应用程序作为粉丝页面发布到 FB 粉丝页面。所以我可以有多个用户可以访问应用程序，但不能访问粉丝页面，作为粉丝页面发布。它符合我的要求。

无论如何，这就是我使用 C# Facebook SDK Beta V5.0.9 的方法。 第一步，确保您尝试发帖的用户帐户能够在粉丝页面上发帖，并且已获得应用授权。

其中大部分内容与 VorTechS 帖子类似，只是对此进行了更多说明。

Dictionary<string,string> fbParams = new Dictionary<string,string>();
                fbParams["message"] = Title;
                fbParams["caption"] = string.Empty;
                fbParams["description"] = string.Empty;
                fbParams["req_perms"] = "publish_stream";
                fbParams["scope"] = "publish_stream";
                //Initialize Your Facebook Client in the manner that suits you, I did it by supplying a saved access token from a single users
                FacebookWebClient fbClient = new FacebookWebClient(<YOUR_ACCOUNT_ACCESS_TOKEN>);
                //Get the listing of accounts associated with the user
                dynamic fbAccounts = fbClient.Get("/me/accounts");

                //Loop over the accounts looking for the ID that matches your destination ID (Fan Page ID)
                foreach (dynamic account in fbAccounts.data) {
                    if (account.id == <DESTINATION_ID_OF_YOUR_FAN_PAGE>) {
                        //When you find it, grab the associated access token and put it in the Dictionary to pass in the FB Post, then break out.
                        fbParams["access_token"] = account.access_token;
                        break;
                    }
                }
                //Then pass your destination ID and target along with FB Post info. You're Done.
                dynamic publishedResponse = fbClient.Post("/" + <DESTINATION_ID_OF_YOUR_FAN_PAGE> + "/feed", fbParams);

要发布消息，您需要授予 manages_pages 权限，并使用“/me/accounts”的结果从粉丝页的帐户中获取访问令牌。

这是我用来将消息本身发布到粉丝页面的方法：

                            var dicParams = new Dictionary<string, object>();
                        dicParams["message"] = stSmContentTitle;
                        dicParams["caption"] = string.Empty;
                        dicParams["description"] = string.Empty;
                        dicParams["name"] = smContent.CmeUrl;
                        dicParams["req_perms"] = "publish_stream";
                        dicParams["scope"] = "publish_stream";

                        // Get the access token of the posting user if we need to
                        if (destinationID != this.FacebookAccount.UserAccountId)
                        {
                            dicParams["access_token"] = this.getPostingUserAuthToken(destinationID);
                        }
                        publishResponse = this.FacebookConnection.Post("/" + destinationID + "/feed", dicParams);

我要感谢您的帖子，这真的很有帮助。对我来说，它仍然在我的 Facebook 页面上发布为我（而不是页面）。我认为这只是我获得令牌的方式。虽然，foreach 循环对我不起作用。所以，我这样做了：

public void postFacebook(object sender, EventArgs e)
{
    //You will get your "myAccessToken" at this adress:
    //https://www.facebook.com/dialog/oauth?client_id=<YOUR_APP_ID>&redirect_uri=<THE_PAGE_YOU_WILL_RECEIVE_YOUR_TOKEN_AT>&scope=offline_access,manage_pages,publish_stream&response_type=token
    string myAccessToken = "<IN_THE_RETURNED_URL_BELOW>";
    string myPageId = "<YOUR_FAN_PAGE_ID>";

    Dictionary<string,string> fbParams = new Dictionary<string,string>();
    fbParams["message"] = "Testing 1 2 test";
    fbParams["caption"] = string.Empty;
    fbParams["description"] = string.Empty;
    fbParams["req_perms"] = "publish_stream";
    fbParams["scope"] = "publish_stream";
    //Initialize Your Facebook Client in the manner that suits you, I did it by supplying a saved access token from a single users
    Facebook.FacebookAPI fbClient = new Facebook.FacebookAPI(myAccessToken);
    //Get the listing of accounts associated with the user
    var fbAccounts = fbClient.Get("/me/accounts");

    //Loop over the accounts looking for the ID that matches your destination ID (Fan Page ID)
    foreach (var account in fbAccounts.Dictionary["data"].Array)
    {
        if (account.Dictionary["id"].String == myPageId)
        {
            //When you find it, grab the associated access token and put it in the Dictionary to pass in the FB Post, then break out.
            fbParams["access_token"] = account.Dictionary["access_token"].String;

            //Update the Access token (to post as the page). If you don't it will post as YOUR personal name.
            fbClient.AccessToken = fbParams["access_token"];
            break;
        }
    }



    //Then pass your destination ID and target along with FB Post info. You're Done.
    dynamic publishedResponse = fbClient.Post("/" + myPageId + "/feed", fbParams);
}

顺便说一下，你需要这个sdk：SDK

在 MVC4 和 C# SDK 中，这达到了我的目标

  [FacebookAuthorize("publish_stream")]
    public ActionResult PostNotification(FacebookContext context)
    {
        var dicParams = new Dictionary<string, object>();
        dicParams["message"] = "đang tập code cho facebook ~@@";
        dicParams["caption"] = "bbbbb";
        dicParams["description"] = "cccccc";
        dicParams["name"] = "http://www.facebook.com";
        dicParams["req_perms"] = "publish_stream";
        dicParams["scope"] = "publish_stream";
        string destinationID = context.UserId;
        context.Client.Post("/" + destinationID + "/feed", dicParams);
        return RedirectToAction("Index");
    }
