因此，我正在开发一个应用程序，您可以在其中发送一首爱情诗，然后将其恢复到您的Facebook墙上翻译。
所以这应该是一个非常简单的任务。我要求access_token和user_id：他们填写表格然后发给我。
当我将应用程序移动到页面选项卡时，我首次遇到重定向问题。
现在发生的事情是，当他在我们的粉丝页面时，我们不再获得“客户”的用户名，尽管他正在访问该应用程序....
因此，一名创始人。这可能取决于：这是我的代码：
<?php

'appId' => 'xxxx',

$user = $facebook->getUser();
if($user){
try {
$userData = $facebook->api('/me');
} catch (FacebookApiException $e) {
die("API call failed");
}
$access_token = $facebook->getAccessToken();

答案 0 :(得分：0)
当您的应用程序位于页面标签中时，您将收到signed_request。解码后，signed_request将包含[部分]用户信息（有关详细信息，请参阅上面的链接）。解码signed_request后，您将能够提取用户ID。从那里开始，需要查询Graph API以检索应包含其名称的用户（公共）信息。查询看起来像这样：
$facebook->api('/USER_ID');
即使对于未对您的应用程序进行身份验证的用户，您也应该能够检索此最小数据：
{
"id": "123",
"name": "'John Skeet",
"first_name": "'John",
"last_name": "Skeet",
"link": "https://www.facebook.com/profile.php?id=123",
"gender": "male",
"locale": "en_UK",
"updated_time": "2012-01-30T01:09:29+0000",
"type": "user"
}
