连接子结果的 GraphQL 参数

Question

我需要帮助以 GraphQL 语法将参数传递给 collections/connections/arrays。

我只是在学习它，在 http://graphql.org/swapi-graphql/

玩 SWAPI

我可以将 id 参数传递给单个类型，如下所示：

query getANewHope {
  film(id: "ZmlsbXM6MQ==") {
    id
    title
  }
}

但是我不知道怎么查询一个collection/connection

的结果

query starships {
  allStarships(id: "c3RhcnNoaXBzOjI=") { # this doesn't work
    edges {
      node(id: "c3RhcnNoaXBzOjI=") { # ...nor this.
        id
      }
    }
  }
}

我想查询集合，因为我想将这两个想法联系起来，例如 "All Starfighter type ships in A New Hope"?

query filmStarships {
  film(id: "ZmlsbXM6MQ==") {
    title
    starshipConnection { #How to limit this?  I can't use (starshipClass: "Starfighter") here...
      edges {
        node { # ...nor here..
          starshipClass # ...nor here.
        }
      }
    }
  }
}




query starships2 {
  starship (id:  "c3RhcnNoaXBzOjI=") { # This doesn't work either
    id # even without an arugment abovce, it says "Unknown argument \"id\" on field \"node\" of type \"StarshipsEdge\"."
  } 
}

Answer 1

您要求的参数必须在架构中实现。 SWAPI 不公开要按 starshipClass 过滤的参数。单击 GraphiQL window 右上角的 Docs 以浏览提供的架构。

如果您正在实施自己的架构，那么在解析器中的 starshipClass 上添加过滤器会非常容易。
