检查登录用户是否喜欢我的Facebook页面

更新时间：2023-09-10 18:57:16

以下是执行步骤：

1）您需要使用此分步指南将用户连接到您的Facebook页面以获取用户基本信息

https://developers.facebook.com/docs/facebook-login/getting-started- web /

  FB.api（'/ me'，function（response）{
 console。 log（'很高兴见到你'+ response.name +'。'）; 
}

2）在知道用户使用Facebook连接后，您需要发出图形GET请求，以了解该用户他喜欢的页面。

  FB.api（'/ me / likes / YOUR_APP_ID'，function（response）{
 console.log（response.data）; 
}

3）然后运行您的业务逻辑（是否将用户下载页面或其他页面）

以上教程的代码也在下面给出

 &LT;身体GT; 
< div id =fb-root>< / div> 
< script> 
 window.fbAsyncInit = function（）{
 FB.init（{
 appId：'YOUR_APP_ID'，// App ID 
 channelUrl：'//www.example.com/ channel.html'，// Channel File 
 status：true，//检查登录状态
 cookie：true，//启用Cookie以允许服务器访问会话
 xfbml：true / /解析XFBML 
}）; 

 FB.Event.subscribe（'auth.authResponseChange'，function（response）{
 if（response.status ==='connected'）{
 testAPI（）; 
} else if（response.status ==='not_authorized'）{
 $（＃btnFB）。show（）; 
 FB.login（）; 
} else {
 $（＃btnFB）。show（）; 
 FB.login（）; 
} 
}）;

};

 code> //异步加载SDK 
（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））; 

 function testAPI（）{
 FB.api（'/ me'，function（response）{
 console.log（'Good to see you，'+ response.name +'。'）; 
}）; 
 FB.api（'/ me / likes / PAGE_ID'，function（response）{
 console.log（response.data）; 
}）; 
}

如何获取PAGE_ID？

这对我有用！：）

OK. So I have no idea on how to do this but you are going to have to talk like a 3 year old to me. I know PHP, HTML, CSS and a tiny smidge of javascript. I want to be able to make a page that gets the users facebook and checks to see if they have liked my Facebook page (https://www.facebook.com/MrDarrenGriffin). If they have, a redirect will direct them to a page. However, If not, it will tell them that to go to the downloads page, they have to like the page. The liking method could be with the embedded like button in the code. After they have liked the page it will go through the check again and if they have successfully liked my page, it will redirect them to the downloads section (or a specified page).

Thanks in advance :D

Here are the steps to do so:

1) You need to use this step by step guide to connect user to your facebook page in order to fetch user basic information

https://developers.facebook.com/docs/facebook-login/getting-started-web/

FB.api('/me', function(response) {
    console.log('Good to see you, ' + response.name + '.');
}

2) After knowing that user is connected using facebook you need to issue the graph GET request to find out about this user that he liked your page or not

FB.api('/me/likes/YOUR_APP_ID', function(response) {
    console.log(response.data);
}

3) And then run your business logic (whether to take user to download page or other page)

Code from the tutorial above is given below too

<body>
<div id="fb-root"></div>
<script>
  window.fbAsyncInit = function() {
  FB.init({
  appId      : 'YOUR_APP_ID', // App ID
  channelUrl : '//www.example.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
});

FB.Event.subscribe('auth.authResponseChange', function(response) {
    if (response.status === 'connected') {
      testAPI();
    } else if (response.status === 'not_authorized') {
  $("#btnFB").show();     
      FB.login();
    } else {
  $("#btnFB").show();         
      FB.login();
    }
});

};

// 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));

function testAPI() {
  FB.api('/me', function(response) {
    console.log('Good to see you, ' + response.name + '.');
  });
  FB.api('/me/likes/PAGE_ID', function(response) {
    console.log(response.data);
  });
}
