我需要获取用户点击Facebook iFrame应用程序的用户ID。在筛选所有虚假信息和过时信息时,我想我已经找到了正确的信息。
当用户点击页面时,我需要让他们授权该应用。在我的PHP中,我这样做:
$facebook = new Facebook($appData);
$user = $facebook->getUser();
if(!$user) {
echo '<script>top.location.href="'.$facebook->getLoginUrl().'";</script>';
die();
}
这给了我授权请求,但然后将我推回到我的服务器,而不是iFrame App的URL(http://app.facebook.com/blah)。我手动构建了URL并尝试将URL设置为app.facebook.com URI,但之后我收到一条错误消息,指出该URL对应用程序无效。
如何在授权后将其重定向回应用?这个应用程序将存在于Facebook内部,一般不在外面访问,因此我不会寻找Facebook Connect登录。

当我摆弄request_uri时,这是我得到的确切错误:
API Error Code: 191
API Error Description: The specified URL is not owned by the application
Error Message: Invalid redirect_uri: Given URL is not allowed by the Application configuration.

您是否尝试过设置redirect_uri
参数。
if(!$user) {
$params = array('redirect_uri' => 'http://app.facebook.com/blah/');
die('<script>top.location.href="'.$facebook->getLoginUrl($params).'";</script>');
}

转到:
http://developers.facebook.com/apps
在您的开发人员应用程序设置中,您需要更改URL设置,以便Facebook知道您的应用程序是一个画布应用程序。在设置中,请务必删除网络标签中的所有网址,然后确保在在Facebook 标签上正确设置了所有网址。

您可以使用图表api
按照示例代码在iframe应用中授权Facebook应用<?php
ob_start();
session_start();
/*
* App Config
*/
$config= array(
'appId' => 'APPID',
'secret' => 'APPSECRET',
'canvas'=>"http://apps.facebook.com/sampleapp/");
$GRAPH_URL = "https://graph.facebook.com/";
$scope = "publish_stream,email";
$auth_url = "https://www.facebook.com/dialog/oauth?client_id=".$config['appId']."&redirect_uri=".urlencode($config['canvas']). "&scope=" . $scope;
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
if(is_array($data)){
$authToken = $data['oauth_token'];
$userId = $data['user_id'];
$_SESSION['auth_token'] = $authToken;
//check for permission//
$permissions = json_decode(curl_get_file_contents($GRAPH_URL . "me/permissions?access_token=" . $authToken), TRUE);
if(array_key_exists('publish_stream', $permissions['data'][0]) ) {

$token_url="https://graph.facebook.com/oauth/access_token";
$response = curlpost($token_url,$post);
$params = explode('&',$response);
if(isset($params[0])){
$token = explode('=',$params[0]);
if($token[0]=='access_token'){
