当我试图创建一个订单时，我总是收到格式错误的请求。我的json看起来像这样。

{
   "intent":"CAPTURE",
   "purchase_units":[
      {
         "items":[
            {
               "name":"Heartless",
               "description":"Short sleeve tshirt 230gram of 100% cotton, Heartless print on front empty back.",
               "quantity":2,
               "unit_amount":{
                  "currency_code":"EUR",
                  "value":25.0
               }
            },
            {
               "name":"NASCAR",
               "description":"Short sleeve tshirt 230gram of 100% cotton, NASCAR car print on front empty back.",
               "quantity":1,
               "unit_amount":{
                  "currency_code":"EUR",
                  "value":25.0
               }
            }
         ],
         "amount":{
            "currency_code":"EUR",
            "value":"75"
         },
         "custom_id":65
      }
   ],
   "application_context":{
      "return_url":"https://localhost:3000/order/success",
      "cancel_url":"https://localhost:3000/cancel"
   }
}

这里是API的文档。https://developer.paypal.com/docs/api/orders/v2/#orders_create我期待着大家的回答。提前感谢！

添加了项目数组的细分，并将应用程序上下文更改为付款来源，因为应用程序上下文已弃用（大部分）

   "purchase_units":[

这是我的错误：

"status": "success",
  "url": {
    "name": "INVALID_REQUEST",
    "message": "Request is not well-formed, syntactically incorrect, or violates schema.",
    "debug_id": "94d5cca2ed833",
    "details": [
      {
        "location": "body",
        "issue": "MALFORMED_REQUEST_JSON",
        "description": "The request JSON is not well formed."
      }
    ],
    "links": [
      {
        "href": "https://developer.paypal.com/docs/api/orders/v2/#error-MALFORMED_REQUEST_JSON",
        "rel": "information_link",
        "encType": "application/json"
      }
    ]
  }
}

这个错误没有改变时，添加'故障'我也有这个之前，但在文档中看到，它是不需要的
