通过Facebook的墙分享一个简单的图像

问题

或者,如果某一天图像脱机:

API错误代码:191

API错误描述:指定的URL不属于应用程序

错误消息:应用程序不拥有重定向uri


我的问题是:我做错了什么?

情景 首先,我加载Facebook的JavaScript SDK:

<script type="text/javascript">
    window.fbAsyncInit = function() {
        FB.init({
            appId: 'xxx',
            channelUrl: '//localhost/channel.html',
            status: true,
            xfbml: true
        });
    };

    (function(d, s, id) {
        var js, fjs = d.getElementsByTagName(s)[0];
        if (d.getElementById(id)) {
            return;
        }
        js = d.createElement(s);
        js.id = id;
        js.src = "//connect.facebook.net/en_US/all.js";
        fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));
</script>
最后,这是我的应用程序:


尝试以下方法

<script type="text/javascript">
function publishOnFacebook() {
FB.ui(
  {
    method: 'feed',
    name: 'Facebook Dialogs',
    link: 'http://localhost/',
    picture: 'http://fbrell.com/f8.jpg',
    caption: 'Reference Documentation',
    description: 'Dialogs provide a simple, consistent interface for applications to interface with users.'
  },
  function(response) {
    if (response && response.post_id) {
      alert('Post was published.');
    } else {
      alert('Post was not published.');
    }
  }
);
}
</script>

<a href="#" onClick="publishOnFacebook()">
    <i class="icons icon-facebook-big"></i></a>

函数publishOnFacebook(){
FB.ui(
{
方法:“提要”,
名称:“Facebook对话”,
链接:'http://localhost/',
图片:'http://fbrell.com/f8.jpg',
标题:“参考文档”,
描述:“对话框为应用程序与用户交互提供了一个简单、一致的界面。”
},
功能(响应){
if(应答和应答后id){
警报(“发布帖子”);
}否则{
警报(“未发布帖子”);
}
}
);
}

Change
redirect\u uri
到前面的Facebook(任何应用程序都可以使用回退)尝试共享的链接
链接:'https://developers.facebook.com/docs/dialogs/“
不是您在设置中指定的应用程序域,尝试将其更改为
http://localhost/myHTMl.html
按照您的建议,在哪里更改
重定向uri
,@AdamZapp?
redirect_uri
is
Site Url
在新的fb API中不推荐应用程序内设置“picture”参数。
