Question

我在CI 2中创建SDK facebook v2.3，但我只获得了姓名和ID用户详细信息，我需要用户登录时发送电子邮件详细信息。

print_r的结果是

数组（[姓名] =＆gt; Alan El-nino Malmsteen [id] =＆gt; 1111310922216558）

我已经创建了权限电子邮件，但仍无效

public function FBLogin()
{
$this->load->library('facebook');
$login_url = $this->facebook->login_url();
$get_user = $this->facebook->get_user();
if($get_user){ 
    //echo $this->facebook->get_email();
    print_r($get_user);
}else{
   redirect('login_url');
}

和图书馆Facebook.php

            <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
        if ( session_status() == PHP_SESSION_NONE ) {
          session_start();

Answer 1

$request = (new FacebookRequest($this->session, 'GET', '/me/?fields=friends,id,name,birthday,email,picture,gender,location,address,email,hometown'))->execute()->getGraphObject()->asArray();

我认为在新版本中，您需要明确地调用它们。另外，请确保您在APP中拥有电子邮件权限。

Answer 2

另一个可能的原因是如果您使用旧的SDK并调用新的Facebook API版本。

EG。我正在使用PHP SDK 3.2.3 版本并调用Facebook API 2.6 。我只能将ID和Name作为返回值。

SDK生成的访问令牌只能获取这两个值。您可以使用图API并测试访问令牌，因为旧API版本会对其进行双重确认。

Answer 3

我需要通过facebook API开发者页面填写所有Facebook配置，特别是徽标，电子邮件，隐私警察网址和说明。

Facebook php SDK只显示名称和ID
