php - Codeigniter Paypal Express Checkout が ShippingAMT と TAXAMT を渡さない

Question

ここに問題があります - フレームワークとして Codeigniter を使用し、Paypal Express Checkout を統合しています。私が使用しているライブラリはCI_MERCHANTであり、非常にうまく機能しますが、送信するパラメーターをprint_rしてからGetTransactionDetailsに要求すると、それらは異なります

ここに私が送っているものがあります：

    Array
(
    [METHOD] => SetExpressCheckout
    [VERSION] => 94.0
    [USER] => ***
    [PWD] => ***
    [SIGNATURE] => ***
    [PAYMENTREQUEST_0_PAYMENTACTION] => Authorization
    [PAYMENTREQUEST_0_CURRENCYCODE] => USD
    [PAYMENTREQUEST_0_AMT] => 37.95
    [PAYMENTREQUEST_0_ITEMAMT] => 35.95
    [PAYMENTREQUEST_0_DESC] => invoice-#test
    [PAYMENTREQUEST_0_TAXAMT] => 1.00
    [PAYMENTREQUEST_0_SHIPPINGAMT] => 1.00
    [L_PAYMENTREQUEST_0_NAME0] => Item_1
    [L_PAYMENTREQUEST_0_DESC0] => 
    [L_PAYMENTREQUEST_0_AMT0] => 35.95
    [L_PAYMENTREQUEST_0_QTY0] => 1

    [PAYMENTREQUEST_0_SHIPTOSTREET] => address1
    [PAYMENTREQUEST_0_SHIPTOSTREET2] => address2

    [PAYMENTREQUEST_0_EMAIL] => email@dot.com
    [PAYMENTREQUEST_0_INVNUM] => 1468808
    [upload] => 1
)

私が得る応答は次のとおりです。

    [L_HANDLINGAMT0] => 0.00
    [L_CURRENCYCODE0] => USD
    [L_TAXABLE0] => false
    [L_AMT0] => 35.95
}

私は次のことを試しました：異なるバージョン宣言を使用しています。バージョン 63.0 から SHIPPINGAMT と TAXAMT が非推奨になったことを知っているので、それを使用してバージョン 61 に設定しましたが、役に立ちませんでした。

また、サンドボックス アカウント内では、「クライアント」には送料の全額ではなく、ITEMAMT のみが請求されます。ただし、表示されている合計がITEMAMT + SHIPPING + TAXであるため、チェックアウト中に金額が渡されます.

誰が何が起こっているのか考えましたか?

感謝。
