Question

我的代码用于在测验表单末尾动态创建Facebook Share Results按钮。除name设置外，代码均正常工作。首先，这是PHP代码：

$ret = <<<EOT
<script type="text/javascript">
  window.fbAsyncInit = function() {
    FB.init({
      appId      : '{$settings_Facebook["appId"]}',
      xfbml      : true,
      version    : 'v2.7'
    });
  };

  (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/sdk.js";
     fjs.parentNode.insertBefore(js, fjs);
   }(document, 'script', 'facebook-jssdk'));

  // calling the API ...
  function postToFeed() {
    var obj = {
      method: 'feed',
      redirect_uri: '{$settings_Facebook['redirect_uri']}',
      link: '{$settings_Facebook['link']}',
      picture: '{$settings_Facebook['picture']}',
      name: '{$settings_Facebook['name']}',
      caption: '{$settings_Facebook['caption']}',
      description: '{$settings_Facebook['description']}',
    };

    function callback(response) {
       //document.getElementById('msg').innerHTML = "Post ID: " + response['post_id'];
    }

    FB.ui(obj, callback);
  }
</script>

<div id="msg" width="100%; height: 50px;"></div>

<div style="float: right; padding: 8px; overflow: hidden;">
    <a href="#" onClick="postToFeed()">Share results!</a>
</div>
EOT;

以上代码在HTML中呈现为：

<script type="text/javascript">
  window.fbAsyncInit = function() {
    FB.init({
      appId      : '439873598753987',
      xfbml      : true,
      version    : 'v2.7'
    });
  };

  (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/sdk.js";
     fjs.parentNode.insertBefore(js, fjs);
   }(document, 'script', 'facebook-jssdk'));

  // calling the API ...
  function postToFeed() {
    var obj = {
      method: 'feed',
      redirect_uri: 'https://example.com/quiz/',
      link: 'https://example.com/quiz/',
      picture: 'https://example.com/images/quiz-categories_0000.jpg',
      name: 'I ranked 1 in this online quiz! Take it yourself!',
      caption: 'EXAMPLE.COM',
      description: 'Aliquam in magna.',
    };

    function callback(response) {
       document.getElementById('msg').innerHTML = "Post ID: " + response['post_id'];
    }

    FB.ui(obj, callback);
  }
</script>

出于我的目的，上述代码和输出完全正确。弹出共享对话框时，预览看起来100％正确，name字段显示为：

I ranked 1 in this online quiz! Take it yourself!

但是发给用户FB页面的帖子包含name字段中的WordPress标语：

My site's custom tagline.

我不能肯定正在使用标语。我略微改变它并没有影响新的Facebook帖子，但它可能会在某个地方缓存。我无法想到这个文本的配置位置 - 恰好也就是网站的标语。：S

为什么Facebook会覆盖我在API调用的name属性中指定的内容？即使它是由FB设计的，我该如何克服这个？

这确实是一个错误，上周四由Facebook证实。 https://developers.facebook.com/bugs/1214328271924404/

我们希望很快就能解决。

使用提要对话框发布后，FB.ui名称属性被覆盖
