如何在JSON中创建列表等效于Kotlin上的列表？

发布于 2025-01-25 02:01:27 字数 526 浏览 1 评论 0原文

我正在学习KTOR并尝试测试我使用示例模型进行的在这里。但是，我不知道如何在KTOR可以阅读并应作为列表的JSON中列出适当的列表。

我已经尝试过：

{
  "number": "2022-04-28",
  "contents": {
    "OrderItem": {
      "item": "Tea",
      "amount": 5,
      "price": 2.99
    },
    "OrderItem": {
      "item": "Coffee",
      "amount": 2,
      "price": 4.99
    }
  }
}

但是每当我尝试发送邮政请求时，我都会遇到内部服务器错误。

I'm learning Ktor and trying to test a POST request implementation I made using the example model given here. However, I have no idea how to make a proper list in JSON that Ktor could read and deserialize as a list.

I've tried:

{
  "number": "2022-04-28",
  "contents": {
    "OrderItem": {
      "item": "Tea",
      "amount": 5,
      "price": 2.99
    },
    "OrderItem": {
      "item": "Coffee",
      "amount": 2,
      "price": 4.99
    }
  }
}

But I get an internal server error whenever I try to send the POST request.

目录应该是列表[]对象的

{
  "number": "2022-04-28",
  "contents": [
    {
      "item": "Tea",
      "amount": 5,
      "price": 2.99
    },
    {
      "item": "Coffee",
      "amount": 2,
      "price": 4.99
    }
  ]
}

contents should be a list [] of objects

{
  "number": "2022-04-28",
  "contents": [
    {
      "item": "Tea",
      "amount": 5,
      "price": 2.99
    },
    {
      "item": "Coffee",
      "amount": 2,
      "price": 4.99
    }
  ]
}
