2创建销售的2checkout调用

Question

我正在使用2checkout api来销售我的网站产品。因此，我调用2checkout api来创建销售，其中我可以调用单个产品的总金额api。它看起来像流动的：

try {
    $charge = Twocheckout_Charge::auth(array(
        "merchantOrderId" => "123",
        "token"      => $_POST['token'],
        "currency"   => 'USD',
        "total"      => $first_bill['amount'],
        "billingAddr" => array(
            "name" => $_POST['b_name'],
            "addrLine1" => $_POST['b_address'],
            "city" => 'Columbus',
            "state" => 'OH',
            "zipCode" => '43123',
            "country" => $_POST['b_country'],
            "email" => $_POST['b_emaill'],
            "phoneNumber" => $_POST['b_phone']
            ),
        "shippingAddr" => array(
            "name" => 'Testing Tester',
            "addrLine1" => '123 Test St',
            "city" => 'Columbus',
            "state" => 'enter code hereOH',
            "zipCode" => '43123',
            "country" => 'USA',
            "email" => 'example@2co.com',
            "phoneNumber" => '555-555-5555'
            )
        ));
    if ($charge['response']['responseCode'] == 'APPROVED') {

        echo $response;exit;
        // echo "Thanks for your Order!";
        // echo "<h3>Return Parameters:</h3>";
        // echo "<pre>";
        // print_r($charge);
        // echo "</pre>";
    }
    else
    {
        $this->Registrationmodel->delete_account($accounts_id);
        echo $charge['response']['responseCode'];
        exit;
    }
} 
catch (Twocheckout_Error $e) 
{
    echo $e->getMessage();
    exit;
}

}

因此，当我尝试单独设置行项目时，如下所示：

try {
    $charge = Twocheckout_Charge::auth(array(
        "merchantOrderId" => "123",
        "token"      => $_POST['token'],
        "currency"   => 'USD',
        //"total"      => $first_bill['amount'],
        "billingAddr" => array(
            "name" => $_POST['b_name'],
            "addrLine1" => $_POST['b_address'],
            "city" => 'Columbus',
            "state" => 'OH',
            "zipCode" => '43123',
            "country" => $_POST['b_country'],
            "email" => $_POST['b_emaill'],
            "phoneNumber" => $_POST['b_phone']
            ),
        "LineItem" => array(
            "duration" => 'Forever',
            "price" => '10',
            "productId" =>'1235',
            "quantity" => '1',
            "recurrence" => '1 Month',
            "tangible" => 'N',
            "type"=>'product'
            ),
        "shippingAddr" => array(
            "name" => 'Testing Tester',
            "addrLine1" => '123 Test St',
            "city" => 'Columbus',
            "state" => 'OH',
            "zipCode" => '43123',
            "country" => 'USA',
            "email" => 'example@2co.com',
            "phoneNumber" => '555-555-5555'
            )
        ));
    if ($charge['response']['responseCode'] == 'APPROVED') {
        $response = $this->return_information($charge['response']['orderNumber']);
        echo $response;exit;
        // echo "Thanks for your Order!";
        // echo "<h3>Return Parameters:</h3>";
        // echo "<pre>";
        // print_r($charge);
        // echo "</pre>";
    }
    else
    {
        $this->Registrationmodel->delete_account($accounts_id);
        echo $charge['response']['responseCode'];
        exit;
    }
} 
catch (Twocheckout_Error $e) 
{
    $this->Registrationmodel->delete_account($accounts_id);
    echo $e->getMessage();
    exit;
}

}

它给我提供了参数错误。有谁能帮上忙吗？如何使用api调用设置行项目？
