如何使用 Facebook 弹出窗口更改登录的宽度和高度?默认情况下,它显示一个 450x260 像素的弹出窗口,因此我们看不到登录表单(附加捕获)。如何更改弹出窗口的大小?
默认弹出窗口大小,此处看不到登录表单:
我们需要调整它的大小,以便我们可以看到登录表单:
我尝试了FB.ui 中建议的解决方案并设置弹出窗口大小无济于事。任何帮助,将不胜感激。
这是我的完整代码:
<?php
session_start();
define('YOUR_APP_ID', 'myidhere');
define('YOUR_APP_SECRET', 'mysecrethere');
function get_facebook_cookie($app_id, $app_secret)
{
$signed_request = parse_signed_request(@$_COOKIE['fbsr_' . $app_id], $app_secret);
$signed_request['uid'] = $signed_request['user_id']; // for compatibility
if (!is_null($signed_request))
{
$access_token_response = file_get_contents("https://graph.facebook.com/oauth/access_token?client_id=$app_id&redirect_uri=&client_secret=$app_secret&code={$signed_request['code']}");
parse_str($access_token_response);
$signed_request['access_token'] = $access_token;
$signed_request['expires'] = time() + $expires;
}
return $signed_request;
}
function parse_signed_request($signed_request, $secret)
{
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$sig = base64_url_decode($encoded_sig);
$data = json_decode(base64_url_decode($payload), true);
if (strtoupper($data['algorithm']) !== 'HMAC-SHA256') {
error_log('Unknown algorithm. Expected HMAC-SHA256');
return null;
}
$expected_sig = hash_hmac('sha256', $payload, $secret, $raw = true);
if ($sig !== $expected_sig) {
error_log('Bad Signed JSON signature!');
return null;
}
return $data;
}
function base64_url_decode($input)
{
return base64_decode(strtr($input, '-_', '+/'));
}
if (isset($_COOKIE['fbsr_' . YOUR_APP_ID]))
{
$cookie = get_facebook_cookie(YOUR_APP_ID, YOUR_APP_SECRET);
$user = json_decode(@file_get_contents('https://graph.facebook.com/me?access_token=' .$cookie['access_token']));
}
