使用Facebook登录Javascript SDK获取用户数据 [英] Getting userdata using Facebook Login Javascript SDK

问题描述

我已经使用Javascript SDK来使用Facebook登录，但现在我已经连接了，我不知道如何捕获用户的数据并将其发送到一个codeigniter控制器上。我决定使用ajax，但如果我还没有我的facebook userdata，我不知道如何实现它。

I've used the Javascript SDK to use Facebook login, but now I'm connected, I don't know how to capture the user's data and send it on a codeigniter controller. I decided to use ajax, but I don't know how to implement it if I still don't have my facebook userdata.

if (response.status === 'connected') {

//How do I get userdata??
// I decided to use ajax

$.ajax({
    type : 'POST',
    data : 'userdata='+ //but I don't know how I would put my data,
    url : '<?php echo site_url("somecontroller/somefunction");?>',
    success :   function(){

    }
});

}

另外，如何获取数据放在一个数组，所以我可以在发送给控制器时使用1个变量？

Also, how do I get the data to be placed in an array so I could just use 1 variable when sending it to my controller?

推荐答案

验证用户是否连接后，您访问facebook api for curent用户：

After you verify if user is connected you access facebook api for curent user :

FB.api('/me', function(info) {
//for example facebook id for curent user 
var id = info.id;
//you can view all data which you can use, if you need more data ask for more permisson
console.log(info);

//here you can ajax data for your need

$.ajax({
    type : 'POST',
    data : info, //all data 
    url : '<?php echo site_url("somecontroller/somefunction");?>',
    success :   function(){

    }
});

//or only date which you need

$.ajax({
  type: "POST",
  url: '<?php echo site_url("somecontroller/somefunction");?>',
  data: { id: info.id, fullname: info.name },
   success :   function(){

    }
})

});
