获取接口值的类型

Question

我有以下可用界面：

export interface SchemaAttributes {
  [key: string]: (
    SchemaAttributeDefinition<NumberConstructor, number>
    | SchemaAttributeDefinition<[NumberConstructor], number[]>
    | SchemaAttributeDefinition<DateConstructor, Date>
    | SchemaAttributeDefinition<StringConstructor, string>
    | SchemaAttributeDefinition<[StringConstructor], string[]>
    | SchemaAttributeDefinition<ObjectConstructor, Object>
    | SchemaAttributeDefinition<ArrayConstructor, Array<any>>
    | SchemaAttributeDefinition<any, any>
    | RawSchemaAttributeDefinition<any, any>
    | NumberConstructor
    | [NumberConstructor]
    | DateConstructor
    | StringConstructor
    | [StringConstructor]
    | ObjectConstructor
    | ArrayConstructor
  )
}

如何访问分配给key的组合类型？

Answer 1

您可以为此使用索引类型查询：

type Foo = SchemaAttributes['string'];
