GraphQl查询中的嵌套字段如何获得自己的参数

发布于 2025-01-19 18:05:07 字数 711 浏览 1 评论 0原文

我正在研究基于光标的分页，该分页需要嵌套字段才能访问ARGS。到目前为止，我一直无法将Args带到其所需的领域。

   type Game {
    players(first: Int, after: String, last: Int, before: String): GameToPlayerConnection
  }

  game(id: GameID!): Game

我只能访问传递给game的args，而不是传递给players的args。

 game: async (parent: any, args: { id: string; first: number; last: number; after: 
       string; before: string; }, _ctx: any, info: any) => 
        {
        const { id, first, last, after, before } = args;
        console.log("args", args);
        }



  game(id: 'fortnite', first: 3){
    players(first: 2){
     ....
     }
    }

我正在尝试访问传递给players的args

I'm working on a cursor based pagination that requires the a nested field to access the args. So far, i've been unable to get the args to its desired field.

   type Game {
    players(first: Int, after: String, last: Int, before: String): GameToPlayerConnection
  }

  game(id: GameID!): Game

I am able to only access the args passed to the game and not the args passed to the players.

 game: async (parent: any, args: { id: string; first: number; last: number; after: 
       string; before: string; }, _ctx: any, info: any) => 
        {
        const { id, first, last, after, before } = args;
        console.log("args", args);
        }



  game(id: 'fortnite', first: 3){
    players(first: 2){
     ....
     }
    }

I am trying to access the args passed to the players

没错。每个解析器只能访问其自身属性的参数。每个对象也都有其自己的一组解析器，因此您需要一个对象进行查询，另一个对象进行游戏：

const resolvers = {
  Query: {
    game: async (parent, { id }, context, info) {
      return games.load(id);
    },
  },
  Game: {
    players: async ({ id }, { first, last, before, after }, context, info) {
      return playersByGame({
        gameId: id,
        first,
        last,
        before,
        after,
      });
    },
  },
};

That's correct. Every resolver can only access the arguments for its own property. Each object also has its own set of resolvers, so you need one object for Query, and another for Game:

const resolvers = {
  Query: {
    game: async (parent, { id }, context, info) {
      return games.load(id);
    },
  },
  Game: {
    players: async ({ id }, { first, last, before, after }, context, info) {
      return playersByGame({
        gameId: id,
        first,
        last,
        before,
        after,
      });
    },
  },
};
