php - 无法在 magento 2 rest 中使用 paypal 下订单

Question

我正在开发一个仅使用 ma​​gento 2 rest api 的电子商务 mobiloe 应用程序。这是调用 REST API 以下订单的流程。

1.创建购物车

API -->{{url}}/index.php/rest/V1/carts/mine

此 api 将返回一个唯一的购物车 ID

2.将产品添加到购物车

api --> {{url}}/index.php/rest/V1/carts/mine/items

正文 ->

{
 "cart_item": {
     "quote_id": cartId,
     "sku": skuName,
     "qty": 1
     }
}

3.估计运输方式

url --> {{url}}/index.php/rest/V1/carts/mine/estimate-shipping-methods

正文 ->

{
    "address": {
        "region": "Trivandrum",
        "region_id": 12,
        "region_code": "CA",
        "country_id": "IN",
        "street": [
            "Amstor house",
            "Eramam"
        ],
        "telephone": "5656565454",
        "postcode": "670390",
        "city": "Kazhakuttam",
        "firstname": "Peter",
        "lastname": "K",
        "same_as_billing": 0,
        "save_in_address_book": 0
    }

}

这将根据送货地址返回所有可能的送货方式。在我的例子中，结果是

[
  {
    "carrier_code": "freeshipping",
    "method_code": "freeshipping",
    "carrier_title": "Free Shipping",
    "method_title": "Free",
    "amount": 0,
    "base_amount": 0,
    "available": true,
    "error_message": "",
    "price_excl_tax": 0,
    "price_incl_tax": 0
  }
]

4)保存发货信息

url --> {{url}}/index.php/rest/V1/carts/mine/shipping-information

body 数据->

{
    "addressInformation": {
        "shipping_address": {

            "region": "Trivandrum",
            "region_id": 12,
            "region_code": "CA",
            "country_id": "IN",
            "street": [
                "Amstor house",
                "Eramam"
            ],
            "telephone": "5656565454",
            "postcode": "670390",
            "city": "Kazhakuttam",
            "firstname": "Peter",
            "lastname": "K",

        },
        "billing_address": {
            "region": "Trivandrum",
            "region_id": 12,
            "region_code": "CA",
            "country_id": "IN",
            "street": [
                "Amstor house",
                "Eramam"
            ],
            "telephone": "5656565454",
            "postcode": "670390",
            "city": "Kazhakuttam",
            "firstname": "Peter",
            "lastname": "K",
        },
        "shipping_method_code": "freeshipping",
        "shipping_carrier_code": "freeshipping"


    }
}

这将返回所有可能的付款方式。我在这里使用 paypal_express 进行支付。

5.使用paypal插件支付

在这里，我将使用 paypal cordova plugin 支付金额.同时在paypal账户中配置IPN [{{url}}/paypal/ipn/]

此 api 将返回以下数据，

{
   "client": {
       "environment": "sandbox",
       "paypal_sdk_version": "2.14.4",
       "platform": "Android",
       "product_name": "PayPal-Android-SDK"
   },
   "response": {
       "create_time": "2016-11-19T05:25:46Z",
       "id": "PAY-5VS11410F5341972MLAX6ETA",
       "intent": "sale",
       "state": "approved"
   },
   "response_type": "payment"
}

5.保存付款并下单

url --> {{url}}/index.php/rest/V1/carts/mine/payment-information

数据->

{
    "cartId": 3,
    "billingAddress‌​": {
        "region": "Trivandrum",
        "region_id": 12,
        "region_code": "CA",
        "country_id": "IN",
        "street": [
            "Amstor house",
            "Eramam"
        ],
        "telephone": "5656565454",
        "postcode": "670390",
        "city": "Kazhakuttam",
        "firstname": "Peter",
        "lastname": "K"
    },
    "paymentMethod": {
        "method": "paypal_express"

    }
}

但是这个api会返回

{
  "message": "PayPal gateway has rejected request. Invalid token (#10410: Invalid token)."
}

上述流程中是否缺少用于捕获付款的 API。请帮助我。

Answer 1

Paypal Express 支付方式不支持在线捕获。无法通过 Magento API 接口(interface)获得像 Checkout 那样的完整订单创建流程。无法更改订单状态和处理付款。作为解决方法，请尝试以下操作:

1. 创建自定义付款方式
2. 仅为 REST API 启用(不在网站结帐页面上)
3. 在使用 rest api 付款时使用此方法(在使用您的 android/ios SDK 成功付款后)
4. 下订单后，通过 paypal sdk 支付返回发送交易 id(PAY-xxxxx) 以保存交易。(告诉您的服务器端实现此调用)。
