除了位置,其他一切都很好。实际的城市/州没有遇到。而是显示单词 Array。我在数据库中的字段类型是文本,但我已经通过 mysql 尝试了每种字段类型。HTML 文件是 JSON,涉及字段名称。我对此很陌生,因此不胜感激。
这是我的 php 文件:
<? ob_start(); ?>
<?php
define('FACEBOOK_APP_ID', '');
define('FACEBOOK_SECRET', '');
// No need to change function body
function parse_signed_request($signed_request, $secret) {
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
// decode the data
$sig = base64_url_decode($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;
}
// check sig
$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($input, '-_', '+/'));
}
if ($_REQUEST) {
$response = parse_signed_request($_REQUEST['signed_request'],
FACEBOOK_SECRET);
/*
echo "<pre>";
print_r($response);
echo "</pre>"; // Uncomment this for printing the response Array
*/
$name = $response["registration"]["name"];
$email = $response["registration"]["email"];
$gender = $response["registration"]["gender"];
$prosecutor = $response["registration"]["prosecutor"];
$location = $response["registration"]["location"];
// Connecting to Database
$con = mysql_connect("my_hosting_site","Database","password");
if (!$response)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("Database", $con);
mysql_query("INSERT INTO my_table (name, email, gender, prosecutor, location)
VALUES ('$name', '$email', '$gender', '$prosecutor', '$location')");
mysql_close($con);
}
$URL="https://www.facebook.com";
header ("Location: $URL");
