Question

我正在使用 paypal sandbox api 来获取使用 paypal sandbox 进行的交易，但出现身份验证失败错误。

来自api的消息响应是：

{"name":"AUTHENTICATION_FAILURE","message":"由于身份验证凭据无效或授权标头丢失，身份验证失败。","links":[{"href":"https://developer.paypal .com/docs/api/overview/#error","rel":"information_link"}]}

我的代码是

    $PAYPAL_SANDBOX = true;
    
    $_GET['PayerID'] = ''; // this value i received after successful payment

                /*get access token*/

function tokenInDb($token_output){

    //print_r($token_output);
    //die;

    global $db;
    global $PAYPAL_DB_TABLE;

    /*insert token in db*/
    $db->insert($PAYPAL_DB_TABLE, [
        'access_token' => $token_output['access_token'], 
        'token_type' => $token_output['token_type'],
        'app_id' => $token_output['app_id'],
        'expires_in' => $token_output['expires_in'],
        'nonce' => $token_output['nonce']
    ]);
    /*insert token in db*/
}

我在哪里做错了，我找不到，但我得到了访问令牌，请帮忙
