问题

我有一堆使用相同接口的异常，这样前端就更容易区分它们来自同一个端点。

我想在 Swagger 中记录，`MyWeirdExpection` 有一个名为 `type` 的属性，其取值为 `my-weird-exception`（它来自一个字符串枚举，如果相关的话）。

这样做是否可能？

类似这样的代码：

```typescript

enum MyEnum {
   MyWeirdExpection: 'my-weird-exception',
   RegularExpection: 'my-regular-expection'
... 更多
}

  @ApiProperty({
    description: '前端可以根据此属性做出反应',
    type: String, // <-----------这里怎么写？
  })
  type: MyEnum.MyWeirdExpection;

再次强调，我的目标是在 Swagger 定义中，说明 MyWeirdExpection.type 是常量 'my-weird-exception'。

I have a bunch of Exceptions that use the same interface, so it is easier for the frontend to distinct between them from the same endpoint.

I want to be able to document in swagger that `MyWeirdExpection` has a property `type` that has the value `my-weird-exception` (it comes from an string ENUM if that is relevant).

Is this possible to do?

Something like:

```typescript

enum MyEnum {
   MyWeirdExpection: &#39;my-weird-exception&#39;,
   RegularExpection: &#39;my-regular-expection&#39;
... more
}



  @ApiProperty({
    description: &#39;Frontend can react on this property&#39;,
    type: String, // &lt;-----------WHAT HERE?
  })
  type: MyEnum.MyWeirdExpection;

Again, my goal is that in the swagger definition, says that MyWeirdExpection.type is the constant 'my-weird-exception'

以下将提供一个名为 MyEnum.MyWeirdExpection 的类型，其值将填充为 'my-weird-exception'：

@ApiProperty({
    description: "按资产类型搜索",
    required: false,
    default: MyEnum.MyWeirdExpection,
    type: MyEnum.MyWeirdExpection
})
type: string | undefined;

@ApiProperty({
    description: "Search by asset type",
    required: false,
    default: MyEnum.MyWeirdExpection,
    type: MyEnum.MyWeirdExpection
})
type: string | undefined;
