Facebook SDK Unity发布

Question

I'm developing an Android game in which I connect to Facebook. If the user is connected, they can publish the application on their Facebook wall.

The problem that in the script InteractiveConsole.cs When the user clicks on the publish button and then the cancel button, I want to show this message: "Not published". When they click on only the publish button and it is published, I want to show the message :"publish".

The problem is that in both cases, when I decide to either publish or cancel, it shows me the message :"publish" on the GUI.

Here is my code:

public GUIText guiFeed;

#region FB.Feed() example

    public string FeedToId = "";
    public string FeedLink = "http://www.google.com";
    public string FeedLinkName = "Test";
    public string FeedLinkCaption = "Test Caption ";
    public string FeedLinkDescription = "Test Deszcription";
    public string FeedPicture = "http://www.selfspark.com/wp-content/uploads/Smiley-Face-Button.jpg";
    public string FeedMediaSource = "";
    public string FeedActionName = "";
    public string FeedActionLink = "";
    public string FeedReference = "";
    public bool IncludeFeedProperties = false;
    private Dictionary<string, string[]> FeedProperties = new Dictionary<string, string[]>();

    public void CallFBFeed()
    {
        Dictionary<string, string[]> feedProperties = null;
        if (IncludeFeedProperties)
        {
            feedProperties = FeedProperties;
        }
        FB.Feed(
            toId: FeedToId,
            link: FeedLink,
            linkName: FeedLinkName,
            linkCaption: FeedLinkCaption,
            linkDescription: FeedLinkDescription,
            picture: FeedPicture,
            mediaSource: FeedMediaSource,
            actionName: FeedActionName,
            actionLink: FeedActionLink,
            reference: FeedReference,
            properties: feedProperties,
            callback: LogCallback
        );
    }


    void LogCallback(FBResult response)
    {
        Debug.Log(response.Text);
        guiFeed.text = "response Feed:"+response.Text;

        if (response.Text == null)
        {
            feedd.text = "not publish";
        }
        else
        {
            feedd.text = " publish";
        }

    }

When Facebook Share is cancelled, there is a true boolean value for cancelled field in response.

First of all, you should parse response JSON from string to a Dictionary, then you should check whether it exists and whether it is positive value, meaning cancelled share.

You should update your code like this:

void LogCallback(FBResult response)
{
    var responseObject = Json.Deserialize(response.Text) as Dictionary<string, object>;
    object cancelled;
    if (responseObject.TryGetValue ("cancelled", out cancelled))
    {
        if( (bool)cancelled == true )
        {
            feedd.text = "not publish";
        }
        else
        {
            feedd.text = "publish";
        }
    }
    else
    {
        feedd.text = "publish";
    }
}
