大家好日子，我有类似按钮的问题。我跟踪了https://developers.facebook.com/docs/reference/plugins/like/中的每一步。我已经应用了一些我在网上找到的解决方案，包括附加的＆＃34; https＆＃34;在js.src中。代码可以在下面看到，我希望你能帮助我们。 ^^

Answer 1

<div id="fb-root"></div>
<script>(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#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
 initialize this script after body tag not before than, than put this div where you want that button and inser your url of page to like in data-href .
 <div class="fb-like" data-href="http://stackoverflow.com/questions/10293545/strange-      error-headers-already-sent-by-output-started-at" data-send="true" data-width="450" data-show-faces="true"></div>

Answer 2

 <script>
   window.fbAsyncInit = function() {
    FB.init({
  appId      : 'YOUR_APP_ID', // App ID
  channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File
  status     : true, // check login status
  cookie     : true, // enable cookies to allow the server to access the session
  xfbml      : true  // parse XFBML
});

// Additional initialization code here
};

  // Load the SDK Asynchronously
    (function(d){
 var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
 if (d.getElementById(id)) {return;}
 js = d.createElement('script'); js.id = id; js.async = true;
 js.src = "//connect.facebook.net/en_US/all.js";
 ref.parentNode.insertBefore(js, ref);
 }(document));
</script>

尝试在head标签中添加javascript sdk

XFBML之类的按钮没有显示
