我有一份正使用氟氯化碳I的书本申请,该书在RIAForge上发现,用于认证用户/申请,并允许许可(,但不再有效。 因此,我准备撰写一个版本的。 Fox s PHP example as CFML. 但是,当我回过来回去找回被证明的人时,我从脸书上发现了以下错误:

OAuth “Facebook Platform”“invalid_code” “Error validating ratification Code”

由于我测试了由他们提供的带我详细内容的购买力平价代码,并做了一些细微的工作,所以在打上手提书时没有问题。 请参看PHP的例子,以及我不得不使用CF的情况。

PHP:

$app_id = "YOUR_APP_ID";
$app_secret = "YOUR_APP_SECRET";
$my_url = "YOUR_URL";

session_start();
$code = $_REQUEST["code"];

if(empty($code)) {
 $_SESSION[ state ] = md5(uniqid(rand(), TRUE)); //CSRF protection
 $dialog_url = "http://www.facebook.com/dialog/oauth?client_id=" 
   . $app_id . "&redirect_uri=" . urlencode($my_url) . "&state="
   . $_SESSION[ state ];

 echo("<script> top.location.href= " . $dialog_url . " </script>");
 }

 if($_REQUEST[ state ] == $_SESSION[ state ]) {
 $token_url = "https://graph.facebook.com/oauth/access_token?"
   . "client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url)
   . "&client_secret=" . $app_secret . "&code=" . $code;

 $response = @file_get_contents($token_url);
 $params = null;
 parse_str($response, $params);

 $graph_url = "https://graph.facebook.com/me?access_token=" 
   . $params[ access_token ];

 $user = json_decode(file_get_contents($graph_url));
 echo("Hello " . $user->name);
 }
 else {
 echo("The state does not match. You may be a victim of CSRF.");
 }

 ?> 

CFML:

<cfset appID = "app_id"/>
<cfset secret_key = "secret_key"/>
<cfset app_url = "app_url"/>
