Question

我正在使用Node JS创建GraphQL服务器。

我正在尝试复制mongo模式，该模式具有一个纯粹用于组织的嵌套对象。这是我的mongo模式：

  var plansSchema = new Schema({
  planName:  {
    type: String,
    required: [true, "Plan name is required"]
  },
  pricing: {
    monthly: Number,
    scanEnvelope: Number,
    initalScan: Number,
    perPage: Number,
    forwardMail: Number,
    forwardParcel: Number,
    shred: Number,
    perMonthPerGram: Number,
    freeStorePerGram: Number,
    setup: Number,
    idFree: Number
  },
  expires: Number,
  private: Boolean,
  deleted: Boolean,
  date: { type: Date, default: Date.now },
});

我正在尝试在GraphQL模式中复制它，到目前为止，我具有以下内容：

const PlanType = new GraphQLObjectType({
  name: "Plan",
  fields: () => ({
    id: { type: GraphQLString },
    planName: { type: GraphQLString },
    pricing: new GraphQLObjectType({
      name: "Pricing",
      fields: () => ({
        expires: { type: GraphQLInt },
        private: { type: GraphQLBoolean },
        monthly: { type: GraphQLInt },
        scanEnvelope: { type: GraphQLInt },
        initalScan: { type: GraphQLInt },
        perPage: { type: GraphQLInt },
        forwardMail: { type: GraphQLInt },
        forwardParcel: { type: GraphQLInt },
        shred: { type: GraphQLInt },
        perMonthPerGram: { type: GraphQLInt },
        freeStorePerGram: { type: GraphQLInt },
        setup: { type: GraphQLInt },
        idFree: { type: GraphQLInt }
      })
    })
  })
});

但是我在GraphiQL中遇到以下错误

   {
  "errors": [
    {
      "message": "The type of Plan.pricing must be Output Type but got: undefined."
    }
  ]
}

设置为{{1}的GraphQLFieldConfigMapThunk或GraphQLFieldConfigMap中的每个字段必须是一个fields对象，该对象必须包含GraphQLFieldConfig，{{1 }}，type等。您无法像对args字段那样将resolve设置为field。换句话说，您的代码应更像这样：

GraphQLObjectType

NodeJS中GraphQL架构中的嵌套对象
