Php 如何获取所有需要访问令牌的facebook数据？
我正在尝试使用facebook PHP SDK从facebook获取用户数据。（我正在codeigniter中开发该站点）。我能够获取所有的基本数据。但我无法获取需要访问令牌的数据。我通过解析url从注销url获取访问令牌参数。但这个代币不起作用。它与主访问令牌不同吗 这是我的控制器文件Php 如何获取所有需要访问令牌的facebook数据？,php,codeigniter,facebook-graph-api,facebook-authentication,Php,Codeigniter,Facebook Graph Api,Facebook Authentication,我正在尝试使用facebook PHP SDK从facebook获取用户数据。（我正在codeigniter中开发该站点）。我能够获取所有的基本数据。但我无法获取需要访问令牌的数据。我通过解析url从注销url获取访问令牌参数。但这个代币不起作用。它与主访问令牌不同吗 这是我的控制器文件 <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class UserRegistration2 ex

它正在工作。在作用域中，我没有从用户处获取“用户喜欢”的权限。这就是我请求用户和应用程序访问令牌的方式。
class UserRegistration2 extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('test/Facebook_model');
}
function index() {
$fb_data = $this->Facebook_model->get_data();
if((!$fb_data['uid']) or (!$fb_data['me'])) {
echo "<a href='" .$fb_data['loginUrl']. "'>Login</a>";
}
else {
$params = null;
parse_str($fb_data['logoutUrl'], $params);
$graph_url = "https://graph.facebook.com/me/music?access_token=" . $access_token;
//$user = json_decode(file_get_contents($graph_url));
echo "<pre>";
print_r($fb_data);
//print_r($user);
//print_r($params);
echo "</pre>";
echo "<a href='" .$graph_url. "'>Get Music</a>";
echo "<a href='" .$fb_data['logoutUrl']. "?access_token=" .$access_token. "'>Logout</a>";
}
}
}
此外：要检索用户令牌，您必须至少拥有该用户的基本权限
class UserRegistration2 extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('test/Facebook_model');
}
function index() {
$fb_data = $this->Facebook_model->get_data();
if((!$fb_data['uid']) or (!$fb_data['me'])) {
echo "<a href='" .$fb_data['loginUrl']. "'>Login</a>";
}
else {
$params = null;
parse_str($fb_data['logoutUrl'], $params);
$graph_url = "https://graph.facebook.com/me/music?access_token=" . $access_token;
//$user = json_decode(file_get_contents($graph_url));

print_r($fb_data);
//print_r($user);

您在哪里调用以获取页面、用户和应用程序访问令牌？这就是我要问的。如何获取访问令牌以将其传递到“graph_url”变量中？如果这是错误的方法，那么请给我一个替代的解决方案。为了将来的参考，请不要公开你的应用程序秘密，这是危险的，并且会对Facebook TOS2不利。让我将您的代码重新发布到新的答案中，并添加标记。谢谢。我忘了把它擦掉。再次感谢。谢谢你的回复。当我把这个url放到浏览器中时，它会显示“access_token=130090207121542 | xm3P_L6SrAMVY3-DZRGbl9E_o6k”。这是我可以传递给“graph url”变量的令牌吗？事实上，我想获取类似于此url的数据，然后我将对其进行解码并将其放入我的数据库中。如果答案有效，请确保将其标记为正确答案，以便其他用户可以找到解决方案。谢谢兄弟。我不知道我们也可以通过这种方式获得访问令牌（$access\u token=$\u SESSION['fb\u 130090207121542\u access\u token']）。我去检查一下，它坏了。该变量返回的令牌与我从注销url提取的令牌相同。每当我把它放在“graph_url”变量中时，它不包含任何数据。
