Question

我试图在facebook上发布图像和链接。我能够登录获取用户详细信息，但我无法发布图像和链接。以下是我使用的代码

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

        {
            if(success){

                Facebook.api("/me",getMeHandler);
                userImg.source=Facebook.getImageUrl(success.uid,"small");
                Facebook.api("/me/statuses",getStatusHandler);

            obj.type ='link';
            Facebook.api("/me/feed",submitPostHandler,obj, "POST");

图像存储在公共服务器上。任何人都可以指出我在哪里做错了???

我不太确定这一行：

Facebook.login(loginHandler,  {perms:"user_birthday,read_stream,publish_stream"});

在空中我正在使用：

Facebook.login(loginHandler, ['email', 'user_birthday', 'read_stream', 'publish_stream']);

当您允许应用程序使用您的数据时，您是否看到这样的内容？

尝试这样：

private function submitPost():void {
        var params:Object =
        {
            message:'My test post of the image',
            picture:'http://actual.path.to.the.jpg',
            link:'',
            name:'',
            caption:'',
            description:'description about image',
            source:'';
        };

        FacebookDesktop.api('/me/feed', submitPostHandler, params, "POST");            
    };
