限制 JSON 数组仅接受特定类型的项目
问题描述 投票：0回答：1
我有一个中等复杂的 JSON 模式，其中包含一个数组，该数组仅接受两种特定类型的项目。由于某种原因，添加第三种类型的项目后，验证成功。你能帮我找到我忽略的东西吗？
我制作了该方案的一小部分，仅包含受影响的部分：

我有这个基于该方案的 JSON：
{
"trainzMeshes": [
{ "comment": "*****************************************************************" },
{ "comment": " STATION NAME DISPLAY - SIZE S " },
{ "comment": "*****************************************************************" },
{ "comment": "---------------------------- Lod 0 ------------------------------" },
{
"trainzMeshComposition": {
"name": "name-display-S-daytime-lod0n",
"blenderExportSpecifications": [
{
"includeObject": [
"Name Display Console - S [lod0]",
"Name Display - S - Default [lod0]"
]
}
]
}
}
]
}
我的 VS Code 验证器以及 Newtonsoft 的验证器（位于 https://www.jsonschemavalidator.net/）发现 JSON 符合该架构，而我希望“includeObject”违反该架构，原因有两个。
- 如果“includeObject”键被认为是子模式“blenderExportSpecification”的一部分，它有几个属性，但它们都不是“includeObject”，而且additionalProperties设置为false。因此，如果它被视为“blenderExportSpecification”的一部分，则会发生违规。
- 如果验证器发现带有“includeObject”的对象不是“blenderExportSpecification”类型的对象，我预计会在数组级别失败，因为它不是两种允许的类型之一。
我尝试了很多东西，例如将“oneOf”更改为“anyOf”，将oneOf > items结构更改为items > oneOf，但我没有办法让它失败。

差异
根据您对附加要求的评论进行编辑：
- 我只想允许一个
对象和任意数量的trainzMesh
对象comment
这是一种方法。
- 始终要求第一个索引是
对象。我们将trainzMesh
作为数组items
来实现。这会创建位置参数。[] - 我添加了约束
以始终至少需要minItems: 1
对象。trainzMesh
是可选的。comment - 任何其他数组项都必须是
对象，并且该对象模式中不允许使用comment
。additionalProperties
