我正在努力让http://developers.facebook.com/docs/reference/fql/上的示例正常工作,但我遇到了一般错误(见下图)
这是我放在页面上的代码:
<?php
$app_id = 'YOUR_APP_ID';
$app_secret = 'YOUR_APP_SECRET';
$my_url = 'POST_AUTH_URL';
$code = $_REQUEST["code"];
//auth user
if(empty($code)) {
$dialog_url = 'https://www.facebook.com/dialog/oauth?client_id='
. $app_id . '&redirect_uri=' . urlencode($my_url) ;
echo("<script>top.location.href='" . $dialog_url . "'</script>");
}
//get user access_token
$token_url = 'https://graph.facebook.com/oauth/access_token?client_id='
. $app_id . '&redirect_uri=' . urlencode($my_url)
. '&client_secret=' . $app_secret
. '&code=' . $code;
$access_token = file_get_contents($token_url);
// Run fql query
$fql_query_url = 'https://graph.facebook.com/'
. '/fql?q=SELECT+uid2+FROM+friend+WHERE+uid1=me()'
. '&' . $access_token;
$fql_query_result = file_get_contents($fql_query_url);
$fql_query_obj = json_decode($fql_query_result, true);
//display results of fql query
echo '<pre>';
print_r("query results:");
print_r($fql_query_obj);
echo '</pre>';
我怎么能开始调试呢?调试工具没有帮助
