我正在尝试从Instagram Basic Display API访问 accESS_TOKEN 。我成功地获得了如下所述的代码，现在我试图将此$_GET['code']传递给accesstoken()，但是没有响应（错误）。

 //sample request demo (string(240))

在下面，我只是删除了#_末尾的$_GET['code']，并将其传递给函数。

$object = new instaAPI();
$code = trim($_GET['code'],"#_"); //removed the tralling #_ from the end.
$access = $object->accesstoken(APP_ID,REDIRECT_URI,APP_SECRET,$code); //calling
echo $access['access_token']; // blank

卷曲功能

class instaAPI
{
    public function accesstoken($app_id,$redirect_uri,$app_secret,$cod)
    {
      $url = 'https://api.instagram.com/oauth/access_token';


      $curl_post = 'app_id='.$app_id. '&redirect_uri='.$redirect_uri.'&app_secret='.$app_secret.'&code='.$cod.'grant_type=authorization_code';
      $ch = curl_init();
      curl_setopt($ch,CURLOPT_URL,$url);
      curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
      curl_setopt($ch,CURLOPT_POST,CURLOPT_SSL_VERIFYPEER,FALSE);
      curl_setopt($ch,CURLOPT_POSTFIELDS,$curl_post);

      $data = json_decode(curl_exec($ch),true);
      $http_code = curl_getinfo($ch,CURLINFO_HTTP_CODE);
      curl_close($ch);
      if($http_code !== 200)            
            throw new Exception('Error : Failed to receieve access token'.'IG_ERROR_TYPE:'.$data['error_type'].'CODE:'.$data['code'].'MESSAGE'.$data['error_message']);


      return $data;

    } 


}

响应或Json响应

Error: Failed to receive access token 

IG_ERROR_TYPE: OAuthException 
CODE:400
MESSAGE: Matching code was not found or was already used

或

{
    "error_type": "OAuthException","code": 400,"error_message": "Matching code was not found or was already used"
}

这时我很困，不胜感激。
