我如何在类型 - graphql中添加具有不同格式的自定义标量来生成GraphQl架构

Question

我试图使用类型 - graphql lib生成GraphQl架构，我希望字段值接受任何数据类型，但仅采用字符串。我创建了一个具有名称setterValuescalar的自定义标

import { ObjectID } from 'mongodb'
import 'reflect-metadata'
import { Field, InputType, Int, ObjectType } from 'type-graphql'
import { DateScalar } from '../scalars/date.scalar'
import { SettingValueScalar } from '../scalars/setting-value.scalar'

@ObjectType()
@InputType('SettingInput')

export class Setting implements MSetting {
readonly _id!: ObjectID

@Field(() => Int)
 id!: number

 @Field({ nullable: true })
  slug?: string

 @Field({ nullable: true })
 domain?: string

 @Field(()=>SettingValueScalar,{ nullable: true })
 value?: string| number | string[] | number[]

 @Field(() => DateScalar, { nullable: true })
 createdAt?: Date

 @Field(() => DateScalar, { nullable: true })
 updatedAt?: Date

 }

量

 import { GraphQLScalarType, Kind } from 'graphql'

 export const SettingValueScalar = new GraphQLScalarType({
 name: 'SettingValue',
 description: 'Setting value scalar type',

 serialize(value: any): any {
  return value
 },
 parseValue(value: any): any {
  return value
 },
 parseLiteral(ast) {
  return last
 },
 })
