I "fixed" this today for i client but not really happy with the solution. But it works.

***将此文件复制到本地文件夹: app/code/core/Mage/Paypal/Model/Api/Nvp.php

It is better if you copy this file to your local folder: app/code/core/Mage/Paypal/Model/Api/Nvp.php

我在606行中添加了此代码(仅用于快速结帐)，因此看起来像这样.

I added this code (Only for the express checkout) on line 606 so it look like this.

$request['SHIPPINGAMT'] = ($request['AMT'] - ($request['TAXAMT'] + $request['ITEMAMT']));

$response = $this->call(self::SET_EXPRESS_CHECKOUT, $request);
$this->_importFromResponse($this->_setExpressCheckoutResponse, $response);

您需要在后端的Paypal帐户中打开转移购物车订单项"

And you need to turn of Transfer Cart Line Items in the paypal moule in the backend

如果有人知道更好的解决方案，那就覆盖运费就让我知道

If somebody knows a better solution then just overwriting the shippingcost let me know
