我的目标是根据属性的存在来更改架构。
这些是我的模式：

sample = {
    "type": "object",
    "properties": {
        "description": {"type": "string", "minLength": 1, "pattern": "^.*\w+.*$"},
        "owner_id": {"type": "string"},
        "privacy_setting": {"type": "string", "enum": ["private","group","account","public"]},
        "iam": iam,
        "timestamp": {"type": "integer", "minimum": 1000000000000, "maximum": 9999999999999},
        "protocols": {"type": "array", "items": protocol},
        "measurements": {"type": "array", "items": measurement}
    },
    "required": ["description","owner_id"],
    "additionalProperties": False
}

existing_sample = {
    "type": "object",
    "properties": {
        "id": {"type": "string"},
        "protocols": {"type": "array", "items": protocol},
        "measurements": {"type": "array", "items": measurement}
    },
    "required": ["id"],
    "additionalProperties": False
}

# final schema
final = {
    "type": "object",
    "patternProperties": {
        "^.+$": {
            "if": {
                "properties": {
                    "id": {"type": "string"}
                }
            },
            "then": existing_sample,
            "else": sample
        }
    },
    "additionalProperties": False
}

这个想法是在“id”属性存在的情况下遵循“existing_sample”模式，并在它丢失的情况下遵循“sample”模式。

当“id”存在时，它会按预期工作，这意味着如果出现未指定的属性，它将引发异常：

不允许附加属性

但如果“id”属性丢失，它将返回异常：

'id' 是必需的属性

好像它仍然遵循“existing_sample”模式。

有任何想法吗？

看来我的条件不对。我需要一个“id”属性，而不仅仅是指定“id”属性模式。
以下按预期工作：

# existing sample schema
existing_sample = {
    "type": "object",
    "properties": {
        "id": {"type": "string"},
        "protocols": {"type": "array", "items": protocol},
        "measurements": {"type": "array", "items": measurement}
    },
    "required": ["id"],
    "additionalProperties": False
}


# sample schema
sample = {
    "type": "object",
    "properties": {
        "owner_id": {"type": "string"},
        "description": {"type": "string", "minLength": 1, "pattern": "^.*\w+.*$"},
        "privacy_setting": {"type": "string", "enum": ["private","group","account","public"]},
        "iam": iam,
        "timestamp": {"type": "integer", "minimum": 1000000000000, "maximum": 9999999999999},
        "protocols": {"type": "array", "items": protocol},
        "measurements": {"type": "array", "items": measurement}
    },
    "required": ["description","owner_id"],
    "additionalProperties": False
}

# condition to choose between existing sample schema to new sample schema
# based on "id" property appearance
condition = {
    "type": "object",
    "if": {
        "required": ["id"],
    },
    "then": existing_sample,
    "else": sample
}

# final schema
final = {
    "type": "object",
    "patternProperties": {
        "^.+$": condition
    }
}
