我应该在 graphql 模式文件中将每个对象写两次作为“输入"和“类型"吗 [英] Should I write two times each objects as 'input' and 'type' in a graphql schema file

问题描述

我必须在 GraphQL 中使用 Java 对象作为响应和请求.

I have to use a Java object in GraphQL in response as well as in request.

我是否应该在 GraphQL 模式文件中将每个对象写两次作为输入"和类型"?用于在请求和响应中获取该对象.

Should I have to write two times each objects as 'input' and 'type' in a GraphQL schema file? For getting that object in request as well as in response.

我应该用 input 和 type 定义同一个对象两次吗?

Should I define the same object two times with input and type?

文件:test.graphqls

input Employee {
  id: Integer
  name: String
  dept: String
  active: String
}

type Employee {
  id: Integer
  name: String
  dept: String
  active: String
}

推荐答案

是的，因为输入和输出类型的类型系统规则非常不同.输入类型不能是联合，不能实现接口等，所以你不能简单地为这两个目的使用相同的定义.

Yes, because the type system rules are very different for input and output types. Input types can not be unions, can not implement interfaces etc, so you can not simply use the same definition for both purposes.

此外，您必须为每种类型指定一个唯一名称.所以它应该是 Employee 和 EmployeeInput 例如.

Moreover, you must give each type a unique name. So it should be Employee and EmployeeInput for example.
