Apollo/GraphQL 具有不同参数的相同查询 [英] Apollo / GraphQL Same Query with Different Parameters

问题描述

我将如何使用不同参数进行 Apollo 查询.假设我的应用具有用户的概念，并且我希望我的 API 能够通过 ID 或用户名找到用户.

How would I go about having an Apollo query with different parameters. Let's say my app has the concept of users and I want my API to be able to find a user either by ID or username.

我好像做不到

type Query {
  user(id: ID!): User
  user(username: String!): User
}

我必须求助于这样的事情吗

do I have to resort to something like this

type Query {
  userById(id: ID!): User
  userByUsername(username: String!): User
}

推荐答案

创建一个以 ID 和用户名作为字段的新输入类型，并将其指定为参数.

Create a new input type with ID and username as fields and specify it as parameter.

type Query {
  getUser(filters:UserFilter): User
}

input UserFilter{
    ID : Int,
    Username : String
}

查询应该是这样的......

Query should look like this ...

Query{
 getUser(filters:{ID:123123})
}

OR 用户名过滤器

Query{
 getUser(filters:{Username:"Tom"})
}
