Javascript 基于枚举的AJV if-then-else条件类型

我搜索了在AJV模式中使用

if-then-else

的示例，但没有找到属性类型和所需列表根据另一个属性的值更改的特定情况

案例： 我需要升级

userSchema

，这样如果属性

role

=

superuser

，那么

customer\u id

既可以为空，也不需要

const userSchema: Schema<UserItem> = {
  $schema: 'http://json-schema.org/draft-07/schema#',
  type: 'object',
  required: ['id', 'email', 'customer_id'],
  additionalProperties: false,
  properties: {
    id: {
      type: 'string',
      format: 'uuid'
    },
    email: {
      type: 'string',
      format: 'email'
    },
    customer_id: {
      type: 'string',
      format: 'uuid'
    },
    role: {
      anyOf: [
        { type: 'null' },
        { enum: Object.values(UserRole) }
      ]
    }
  }
}

经过多次实验，我发现诀窍在于

customer\u id

属性必须初始化为空，而

role

属性需要进行依赖性检查

...
  properties: {
    id: {
      type: 'string',
      format: 'uuid'
    },
    email: {
      type: 'string',
      format: 'email'
    }
    customer_id: {},
    role: {
      anyOf: [
        { type: 'null' },
        { enum: Object.values(UserRole) }
      ]
    }
  },
  if: {
    dependencies: { role: ['role'] },
    properties: { role: { const: UserRole.Superuser } }
  },
  then: {
    properties: { customer_id: { anyOf: [{ type: 'null' }, { type: 'string', format: 'uuid' }] } }
  },
  else: {
    properties: { customer_id: { type: 'string', format: 'uuid' } }
  }

// Valid
{
    "id": "id",
    "email": "foo@bar.com",
    "role": "superuser",
    "customer_id": null
},
{
    "id": "id",
    "email": "foo@bar.com",
    "role": "superuser"
},
{
    "id": "id",
    "email": "foo@bar.com",
    "role": "null",
    "customer_id": 'some-uuid...'
},
{
    "id": "id",
    "email": "foo@bar.com",
    "role": "user",
    "customer_id": 'some-uuid...'
}

// Invalid
{
    "id": "id",
    "email": "foo@bar.com",
    "role": "user",
    "customer_id": null
},
{
    "id": "id",
    "email": "foo@bar.com",
    "role": "user"
},
{
    "id": "id",
    "email": "foo@bar.com",
    "role": "superuser",
    "customer_id": 'nonUuidString'
}

...
  properties: {
    id: {
      type: 'string',
      format: 'uuid'
    },
    email: {
      type: 'string',
      format: 'email'
    }
    customer_id: {},
    role: {
      anyOf: [
        { type: 'null' },
        { enum: Object.values(UserRole) }
      ]
    }
  },
  if: {
    dependencies: { role: ['role'] },
    properties: { role: { const: UserRole.Superuser } }
  },
  then: {
    properties: { customer_id: { anyOf: [{ type: 'null' }, { type: 'string', format: 'uuid' }] } }
  },
  else: {
    properties: { customer_id: { type: 'string', format: 'uuid' } }
  }
