Question

我正在尝试合并实现自己的nodeDefinitions的2个模式。一种模式使用globalId，如下所示：

const UserType = new GraphQLObjectType({
  name: 'User',
  interfaces: () => [nodeInterface],

  fields: () => ({
    id: globalIdField('User'),
...

其他模式使用自己的自定义ID来实现这种节点接口

const Node = new GraphQLInterfaceType({
    name: 'Node',
    description: 'Generic Node to fetch single parts of the graph.', 
    fields: {
        id: { type: new GraphQLNonNull(entries.types.ariseId) }
    },

错误

   ]
  }

Relay server spec说const oneToTen = Array.from(Array(2).keys()); const obj = oneToTen.reduce((acc, cur) => { acc[cur] = { x: Math.floor(Math.random() * 10), y: Math.floor(Math.random() * 10) } return acc; }, {}); console.log(obj);的类型必须完全

Node

所以您的第二个片段可能是错误的（或者至少不符合规范）。

话虽如此，the ID type可以表示任何字符串或数字值，所以很容易将第二个片段更改为使用纯interface Node { id: ID! }。在ID接口的定义和Node字段本身中都是如此。
