我在facebook SDK上遇到了一些麻烦,特别是检索了访问令牌。该应用程序已在Facebook上正确设置并已获得许可。据我所知,代码是正确的,我不确定getAccessToken()出了什么问题。
$ facebook-> getAccessToken(); 正在返回“12345678 | abcdefghijklmnop”,基本上是某种由App ID和Secret ID组成的变量由|
分隔$ facebook-> getUser(); 正在返回' 0 '
<?php
require_once("facebook.php"); //Up-to-date SDK files from Git
$app_id = "12345678"; //replaced with fake
$app_secret = "abcdefghijklmnop"; //replaced with fake
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true; //I have tried 'false' here as well
));
$token = $facebook->getAccessToken();
?>
提前谢谢!

来自Facebook SDK:
public function getAccessToken() {
if ($this->accessToken !== null) {
return $this->accessToken;
}
$this->setAccessToken($this->getApplicationAccessToken());
$user_access_token = $this->getUserAccessToken();
if ($user_access_token) {
$this->setAccessToken($user_access_token);
}
return $this->accessToken;
}
protected function getApplicationAccessToken() {
return $this->appId.'|'.$this->appSecret;
}
当您有用户签名时,您的访问令牌将是APP ID|APP SECRET
应用程序令牌,或A RANDOM TOKEN HERE
,即用户访问令牌:
$facebook->getUser();
当getUser()
返回0
(与false
相同且用户未签名)时,您需要为您的申请申请登录和授权(如果尚未授权) :
if (!$facebook->getUser())
{
$login_url = $facebook->getLoginUrl(array(
'scope' => 'publish_stream' // Permissions goes here
)
);
?>
<script type="text/javascript">
top.location.href = " <?php echo $login_url; ?>";
</script>
<?php
exit;
}
