几年前，我为Facebook开发了应用程序，但现在似乎无法使用旧方法来获取用户信息（id、姓名等）并在用户墙上发布数据。
我曾经这样使用过，但现在它会让我返回空白屏幕：
require_once('FacebookAPI/Facebook.php');
$facebook = new Facebook(array(
'appId' => 'xxxxx',
'secret' => 'xxxxx',
));
$user = $facebook->getUser();
if ($user)
{
try
{
#Code below to post data on user's wall
# Photo Caption
$photoCaption = 'Just used app';
$imageUrl = ('http://example.com'); // Example URL
$link = ('http://www.facebook.com/page/app_xxxx?ref=ts');
# Post Data for Photos API
$post_data = array(
'message' => $photoCaption,
'link' => $link,
'caption' => 'Caption text'
);
$apiResponse = $facebook->api('/me/feed', 'POST', $post_data);
?>
#Code below to show app
<html>
<body bgcolor="#ffffff">
<center>
// link to my app
</center>
</body>
</html>
// Code below to get user's information (name, id)
<?php
$user_profile = $facebook->api('/me');
$coded = $_REQUEST['code'];
$name = $user_profile['name'];
$id = $user_profile['id'];
session_start();
$_SESSION['name'] = $name;
$_SESSION['id'] = $id;
}
catch (FacebookApiException $e)
{
$user = null;
error_log($e);
}
}
else
{ # Code below to get access from user
$redirectUri = 'http://www.facebook.com/mypage/app_xxxx?ref=ts';
$loginUrl = $facebook->getLoginUrl( array(
'scope' => 'publish_stream,photo_upload',
'redirect_uri' => $redirectUri
));
echo("<script>top.location.href = '" . $loginUrl . "';</script>");
}
有人能帮我成功获取用户名id吗？
您可以尝试此代码。希望你已经下载了最新的php-sdk，你有appid，app des
include_once "php-sdk/src/facebook.php";
$app_id = 'your app id';
$facebook = new Facebook(array(
'appId' => 'your app id',
'secret' => 'your app secret'
));
$user = $facebook->getUser();
if ($user) {
$me = $facebook->api('/me');
$name= $me['name'];
$fid=$me['id'];
}
else
{
$loginUrl = "http://www.facebook.com/dialog/oauth?client_id=" .
$app_id . "&redirect_uri=" . urlencode($app_url) . "&scope=email";
echo("<script> top.location.href='" . $loginUrl . "'</script>");
}
