在Facebook连接中，我如何检查用户是否是我的Facebook页面的粉丝？有可能跟踪吗？ [英] In facebook connect, how can I check if a user is a fan of my facebook page? Is it possible to track?

问题描述

我正在尝试确定用户是否是Facebook粉丝。我加载了facebook JS库并初始化：

 < script type =text / javascriptsrc =http：// static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US\"></script> 
 
 FB_RequireFeatures（[XFBML，Connect，Api]，function（）{FB.init（my_api_key，xd_receiver.htm）}）; 
 
 FB.ensureInit（function（）{
 FB.ApiClient.pages_isFan（my_profile_id，some_UID，callback）; 
}）; 
  

但是当我用FB.ApiClient.pages_isFan调用API客户端时，我收到一个JS错误 -

  FB.ApiClient未定义
  

我也使用FBML粉丝标签显示成为粉丝按钮：

  ; fb：fan profile_id =my_profile_idstream =0connections =10logobar =1width =300>< / fb：fan> 
  

当点击成为粉丝按钮或用户有成功成为粉丝。

业务逻辑非常简单 - 如果他们成为粉丝，请在我的数据库中跟踪。然后，如果他们再次尝试成为粉丝，请查看图书馆是否是粉丝，如果他们是粉丝，说你已经是粉丝，如果没有，请显示该小部件。使用新的 JS SDK ：

 < fb：login-button perms =user_likes > 
授予允许访问权限的权限
< / fb：login-button> 
 
< button onclick =checkDoesLike（）>检查用户是否喜欢页面< / button> 
 
< h1>像这个应用程序的页面< / h1> 
< fb：like-box profile-id =184484190795>< / fb：like-box> 
 
< script> 
 window.checkDoesLike = function（）{
 FB.api（{method：'pages.isFan'，page_id：'184484190795'}，function（resp）{
 if（resp）{ 
 Log.info（'你喜欢应用程序'）; 
} else {
 Log.error（你不喜欢应用程序）; 
} 
}）; 
}; 
< / script> 
  

一个工作示例： http://fbrell.com/fb.api/does-like

I am trying to determine if a user is a facebook fan. I load the facebook JS library and initialize:

<script type="text/javascript" src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US"></script>

FB_RequireFeatures(["XFBML","Connect","Api"], function() { FB.init("my_api_key","xd_receiver.htm") });

FB.ensureInit(function () {     
        FB.ApiClient.pages_isFan(my_profile_id,"some_UID",callback);
    });

However when I call the API client with FB.ApiClient.pages_isFan, I get a JS error -

FB.ApiClient is undefined

I am also using the FBML fan tag to display the "become a fan" button:

<fb:fan profile_id="my_profile_id" stream="0" connections="10" logobar="1" width="300"></fb:fan>

And would like to be notified when either the "become a fan" button is clicked or a user has successfully become a fan.

The business logic is pretty simple - If they become a fan, track it in my database. Then if they try to become a fan again, check with the library if they are a fan and say "You are already a fan" if they are a fan, show the widget if not.

解决方案

Using the new JS SDK:

<fb:login-button perms="user_likes">
  Grant Permissions to Allow access to Likes
</fb:login-button>

<button onclick="checkDoesLike()">Check if user Likes the Page</button>

<h1>Like this Application's Page</h1>
<fb:like-box profile-id="184484190795"></fb:like-box>

<script>
window.checkDoesLike = function() {
  FB.api({ method: 'pages.isFan', page_id: '184484190795' }, function(resp) {
    if (resp) {
      Log.info('You like the Application.');
    } else {
      Log.error("You don't like the Application.");
    }
  });
};
</script>
