有没有一种更简单的方法可以使用模式将文件名用作 json 文件中的值

Question

我想使用文件名作为 json 文件中属性的值，并对它们进行智能感知。

使用 json-schema 中的博客文章示例。

{ 
    "title": "New Blog Post", 
    "content": "This is the content of the blog post...", 
    "publishedDate": "2023-08-25T15:00:00Z", 
    "author": {
        "username": "authoruser",
        "email": "[email protected]"
    },
    "tags": ["Technology", "Programming"]
}

我希望标签的允许值是标签文件夹中的文件名，因此在这种情况下，我将拥有

tags/Technology.json

和

tags/Programming.json

并可能显示文件中的一些信息（例如描述）。例如，

Technology.json

可能看起来像这样。

{
    "name": "Technology (Modern)",
    "description": "Posts about technology created after the year 2000"
}

根据我的发现，我似乎必须从这些 json 文件生成一个架构文件，例如

{
    "type": "array",
    "items": {
        "anyOf": [
            {
                "const": "Technology",
                "description": "Posts about technology created after the year 2000"
            },
            {
                "const": "Programming",
                "description": "Posts about any kind of programming"
            }
        ]
    },
    "uniqueItems": true
}

并将其用作我想要使用它的模式标签中的

$ref

。

有没有我缺少的更简单的方法可以做到这一点？我知道这已经很简单了，但我觉得我只是忽略了一些东西。

Answer 1

文件名可以像字典一样映射键，使用

propertyNames

和

pattern

作为键。然后使用

additionalProperties

和模式来定义所需的模式

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "type": "object",
    "required": ["tags"],
    "properties": {
        "tags": {
            "type": "object",
            "propertyNames": {"pattern": ".json$"},
            "additionalProperties": {
                "$ref": "#/definitions/metadata"
            }
        }
    },
    "definitions": {
      "metadata": {
        "type": "object",
        "required": ["name", "description"],
        "properties": {
          "name": {"type": "string"},
          "description": {"type": "string"}
        }
      }
    }
}

{
    "tags": {
        "technology.json": {
          "name": "Technology (Modern)",
          "description": "Posts about technology created after the year 2000"
        },
        "programming.json": {
          "name": "Technology (Modern)",
          "description": "Posts about technology created after the year 2000"
        },
        "coding.json": {
          "name": "Technology (Modern)",
          "description": "Posts about technology created after the year 2000"
        },
        "crying.json": {
          "name": "Technology (Modern)",
          "description": "Posts about technology created after the year 2000"
        }
    }
}
