【问题描述】：

我使用 paypal rest api 付款资源来更新付款的金额和项目信息；我只想更改商品的价格和税金；和运费；但返回 MALFORMED_REQUEST；让我醉...

request_data 是：

 {
    "op": "replace",
    "path": "/transactions/0/item_list/items/0",
    "value": {
      "name": "hello",
      "quantity": "2",
      "price": "100",
      "currency": "USD",
      "tax": "12"
    }
  },
  {
    "op": "replace",
    "path": "/transactions/0/amount",
    "value": {
      "currency": "USD",
      "total": "224",
      "details": {
        "shipping": "12",
        "subtotal": "200",
        "tax": "12"
      }
    }
  }

并返回： {"name":"MALFORMED_REQUEST","message":"MALFORMED_REQUEST","information_link":"https://developer.paypal.com/docs/api/#MALFORMED_REQUEST","debug_id":"78c05f9b4f21"}

我想确保：
1、可以用paypal更新付款的商品信息
2、是路径“/transactions/0/item_list/items/0”吧
非常感谢！

【解决方案1】：

我正在使用 PayPal Java SDK，并使用以下代码更新购物车商品和总价值。

APIContext context = new APIContext(clientId,clientSecret,environment);

List<Patch> patches = new ArrayList<Patch>();

Amount amount = new Amount();
amount.setCurrency("BRL");
amount.setTotal("100.00");

Patch patch1 = new Patch();
patch1.setOp("replace").setPath("/transactions/0/amount").setValue(amount);

patches.add(patch1);

ItemList items = getItens(order);

Patch patch2 = new Patch();
        patch2.setOp("replace").setPath("/transactions/0/item_list").setValue(items);

patches.add(patch2);

try {

    Payment payment = Payment.get(context, id);

    payment.update(context, patches);

    ...
} ....
