javascript - 为什么我无法验证这个包含包含命名对象的数组的 JSON 文档？

Question

我正在尝试创建一个包含对象数组的 JSON 文档，其中每个对象都有一个特定的“名称”，因此我创建了这个 JSON 文档:

{
    "forecast": [
        "morning": {
            "date": "01/10/2018",
            "min_temp": "12",
            "max_temp": "24",
            "humidity": "2",
            "wind_direction": "SO",
            "wind_force": "12",
            "status": "OK",
            "description": "sdfsdfsdf"
        },
        "afternoon": {
            "date": "01/10/2018",
            "min_temp": "",
            "max_temp": "",
            "humidity": "",
            "wind_direction": "",
            "wind_force": "",
            "status": "",
            "description": ""
        }
    ]
}

如您所见，forecast 数组包含 2 个名为 morning 和 afternoon 的 JSON 对象。

但是这样我在尝试在验证器( https://jsonlint.com/ )上验证这个 JSON 文档时得到以下错误消息，得到的错误是:

Error: Parse error on line 3: ...cast": [ "morning": { "date": "01/1 ----------------------^ Expecting 'EOF', '}', ',', ']', got ':'

以这种格式更改以前的 JSON 文档(基本上删除 JSON 对象名称)，它工作正常并且经过正确验证:

{
    "forecast": [
        {
            "date": "01/10/2018",
            "min_temp": "12",
            "max_temp": "24",
            "humidity": "2",
            "wind_direction": "SO",
            "wind_force": "12",
            "status": "OK",
            "description": "sdfsdfsdf"
        },
        {
            "date": "01/10/2018",
            "min_temp": "",
            "max_temp": "",
            "humidity": "",
            "wind_direction": "",
            "wind_force": "",
            "status": "",
            "description": ""
        }
    ]
}

为什么第一个版本没有经过验证？我可以将对象名称放入 JSON 文档的数组中吗？或者我是否需要添加上午、下午信息作为每个对象的值字段？

您缺少数组元素周围的大括号:

{
    "forecast": [
      {  // HERE
        "morning": {
            "date": "01/10/2018",
            "min_temp": "12",
            "max_temp": "24",
            "humidity": "2",
            "wind_direction": "SO",
            "wind_force": "12",
            "status": "OK",
            "description": "sdfsdfsdf"
        },
        "afternoon": {
            "date": "01/10/2018",
            "min_temp": "",
            "max_temp": "",
            "humidity": "",
            "wind_direction": "",
            "wind_force": "",
            "status": "",
            "description": ""
        }
      }  // HERE
    ]
}
