graphqljs -如何搜索枚举类型

const { GraphQLObjectType, GraphQLSchema, GraphQLString, GraphQLEnumType } = require('graphql');

const ColorEnum = new GraphQLEnumType({
  name: 'Color',
  values: {
    RED: { value: 'red' },
    GREEN: { value: 'green' },
    BLUE: { value: 'blue' },
  },
});

const QueryType = new GraphQLObjectType({
  name: 'Query',
  fields: {
    searchColor: {
      type: GraphQLString,
      args: {
        color: { type: ColorEnum },
      },
      resolve: (_, { color }) => `You searched for ${color}`,
    },
  },
});

const schema = new GraphQLSchema({
  query: QueryType,
});

const { graphql } = require('graphql');

const query = `
  query {
    searchColor(color: RED)
  }
`;

graphql(schema, query).then((result) => {
  console.log(result.data.searchColor); // 输出：You searched for red
});
