FACEBOOK GRAPH / rest api：如何登录我的OWN USER使用PHP更新我的STATUS [英] FACEBOOK GRAPH/rest api: how to LOGIN my OWN USER to update my STATUS with PHP

问题描述

我想通过Facebook图形API来帮助PHP更新FAN-PAGE的状态。 google说：不行。

现在我想用PHP更新自己的用户状态。我的主要问题是如何登录自己的用户到图形API（使用PHP），而不使用浏览器，没有有趣的PHP解决方法。

解决方案>

您需要几件事来更新您的Facebook个人资料或页面的Feed：Facebook应用程序（ client_id ， client_secret ）， profile_id 和 access_token （publish_stream，manage_pages，offline_access权限）

您需要offline_access，因为如果没有，则访问令牌将过期。如果你已经读过你不需要offline_access，如果你已经发布了publish_stream，那么它们只是意味着你不需要它。

发布一篇文章很简单：

  $ data = array（
'access_token'=> $ access_token，
'消息'=>'状态消息'，
）; 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ data）; 
 curl_setopt（$ ch，CURLOPT_URL，https://graph.facebook.com/{$profile_id}/feed）; 
  

现在，如何获取 profile_id 和 access_token ，您可以使用我的应用程序后熊猫，或制作自己的脚本。我会在这里加入：

 ＃arvin castro 
＃http://codecri.me/ 
＃2011年1月16日
 
 $ client_id =''; ＃application id 
 $ client_secret =''; ＃application secret 
 $ callbackURL ='http：//'; ＃这个脚本的URL 
 $ extendedPermissions ='publish_stream，manage_pages，offline_access'; 
 
 session_name（'facebookoauth'）; 
 session_start（）; 
 
 if（isset（$ _ GET ['logout']）和$ _SESSION ['loggedin']）{
 $ _SESSION = array（）; 
 session_destroy（）; 
} 
 
 if（isset（$ _ GET ['signin']））{
 
＃步骤1：将用户重定向到Facebook，为我们的应用程序授予许可
 $ url ='https://graph.facebook.com/oauth/authorize？'。 xhttp :: toQueryString（array（
'client_id'=> $ client_id，
'redirect_uri'=> $ callbackURL，
'scope'=> $ extendedPermissions，
 ））; 
 header（Location：$ url，303）; 
 die（）; 
} 
 
 if（isset（$ _ GET ['code']））{
 
＃步骤2：交换我们有一个访问令牌的代码
 $ data = array（）; 
 $ data ['get'] = array（
'client_id'=> $ client_id，
'client_secret'=> $ client_secret，
'code'=> $ _GET ['code']，
'redirect_uri'=> $ callbackURL，
）; 
 
 $ response = xhttp :: fetch（'https://graph.facebook.com/oauth/access_token'，$ data）; 
 
 if（$ response ['success']）{
 
 $ var = xhttp :: toQueryArray（$ response ['body']）; 
 $ _SESSION ['access_token'] = $ var ['access_token']; 
 $ _SESSION ['loggedin'] = true; 
 
} else {
 print_r（$ response ['body']）; 
} 
} 
 
 if（$ _ SESSION ['loggedin']）{
 //获取配置文件ID 
 $ data = array（）; 
 $ data ['get'] = array（
'access_token'=> $ _SESSION ['access_token']，
'fields'=>'id，name，accounts' 
）; 
 $ response = xhttp :: fetch（'https://graph.facebook.com/me'，$ data）; 
 echo'< pre>'; 
 print_r（json_decode（$ response ['body']，true））; 
 echo'< / pre>'; 
 
} else {
 echo'< a href =？signin>使用Facebook登录< / a>'; 
}

我正在使用我的cURL包装类， xhttp

I want to update the status of a FAN-PAGE by PHP with the help of the Facebook graph api. google says: doesn't work.

Now I want to update my own user status by PHP. My main problem is how to login my own user to the graph api (with PHP), without using a browser and without funny PHP workarounds.

解决方案

You need several things to update your facebook profile or a page's feed: a facebook application (client_id, client_secret), profile_id, and access_token (publish_stream, manage_pages, offline_access permissions)

You need offline_access because if not, then the access token will expire. If you've read that you don't need offline_access if you already have publish_stream specified, they just meant that you don't need it always.

To publish a post is easy:

$data = array(
    'access_token' => $access_token,
    'message' => 'status message',
    );
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_URL, "https://graph.facebook.com/{$profile_id}/feed");

Now how to get the profile_id and access_token, you can use my app post panda, or make your own script. I'll include it here:

# arvin castro
# http://codecri.me/
# January 16, 2011

$client_id     = ''; # application id
$client_secret = ''; # application secret
$callbackURL   = 'http://'; # the URL of this script
$extendedPermissions = 'publish_stream,manage_pages,offline_access';

session_name('facebookoauth');
session_start();

if(isset($_GET['logout']) and $_SESSION['loggedin']) {
    $_SESSION = array();
    session_destroy();
}

if(isset($_GET['signin'])) {

    # STEP 1: Redirect user to Facebook, to grant permission for our application
    $url = 'https://graph.facebook.com/oauth/authorize?' . xhttp::toQueryString(array(
        'client_id'    => $client_id,
        'redirect_uri' => $callbackURL,
        'scope'        => $extendedPermissions,
    ));
    header("Location: $url", 303);
    die();
}

if(isset($_GET['code'])) {

    # STEP 2: Exchange the code that we have for an access token
    $data = array();
    $data['get'] = array(
        'client_id'     => $client_id,
        'client_secret' => $client_secret,
        'code'      => $_GET['code'],
        'redirect_uri'  => $callbackURL,
        );

    $response = xhttp::fetch('https://graph.facebook.com/oauth/access_token', $data);

    if($response['successful']) {

        $var = xhttp::toQueryArray($response['body']);
        $_SESSION['access_token'] = $var['access_token'];
        $_SESSION['loggedin']     = true;

    } else {
        print_r($response['body']);
    }
}

if($_SESSION['loggedin']) {
    // Get Profile ID
    $data = array();
    $data['get'] = array(
            'access_token'  => $_SESSION['access_token'],
            'fields' => 'id,name,accounts',
            );  
    $response = xhttp::fetch('https://graph.facebook.com/me', $data);
    echo '<pre>';
    print_r(json_decode($response['body'], true));
    echo '</pre>';

} else {
    echo '<a href="?signin">Sign in with Facebook</a>';
}

?>

I'm using my cURL wrapper class, xhttp
