<div id="fb-root">sei qui</div>
<script>
  window.fbAsyncInit = function() {
    // init the FB JS SDK
    FB.init({
      appId      : '173721946132851',                        // App ID from the app dashboard
      channelUrl : '//www.ilmiobloggo.net/LOVECALCULATOR/index.php', // Channel file for x-domain comms
      status     : true,                                 // Check Facebook Login status
      xfbml      : true                                  // Look for social plugins on the page
    });

    // Additional initialization code such as adding Event Listeners goes here
  };

  // Load the SDK asynchronously
  (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'));



   FB.api('/me', function(response) {
  alert('Your name is ' + response.name);
});
</script>


</body>
</html>

但FB.api不工作，我不明白为什么，我可以帮助我。我试图获取Apache日志错误到我的房子托管，但没有。

尝试放置

  FB.api('/me', function(response) {
  alert('Your name is ' + response.name);
  });

下面的行

  // Additional initialization code such as adding Event Listeners goes here

但高于

};

e.g

    window.fbAsyncInit = function() {
// init the FB JS SDK
FB.init({
  appId      : '173721946132851',                        // App ID from the app dashboard
  channelUrl : '//www.ilmiobloggo.net/LOVECALCULATOR/index.php', // Channel file for x-domain comms
  status     : true,                                 // Check Facebook Login status
  xfbml      : true                                  // Look for social plugins on the page
});

// Additional initialization code such as adding Event Listeners goes here
FB.api('/me', function(response) {
alert('Your name is ' + response.name);
});
};

你在创建FB之前调用FB.api。这也会产生JavaScript错误，可以在浏览器中找到。不在Apache日志中。尝试打开Chrome Developer工具/ firebug等并查看控制台。

最后一点，您没有任何代码可以让用户使用authorize您的应用。除非用户已授予访问您帐户的权限，否则FB.api（'/ me'）将不会返回正确的响应，因为它需要用户访问令牌

测试API Javascript无法正常工作
