带参数的 graphql 查询不适用于用户 ID

Question

我被迷惑了。我最初创建了用户查询，它给了我错误，我认为是语法错误。但后来我创建了一个相同的车辆查询，效果非常好。我怀疑这和ID有关！类型，但我已经没有线索了。任何帮助，将不胜感激！

这是我的类型定义和解析器。

//类型定义//

   type User {
      id: ID!
      fname: String
      lname: String
      email: String
      password: String
      vehicles: [Vehicle]
    }

    type Vehicle {
      id: ID!
      vin: String
      model: String
      make: String
      drivers: [User]
    }

    type Query {
      users: [User]
      user(id: ID!): User
      vehicles: [Vehicle]
      vehicle(vin: String): Vehicle
    }

//解析器//

   user: async (parent, args, context) => {
        const { id } = args
        return context.prisma.user.findUnique({
          where: {
            id,
          },
        })
      },
   vehicle: async (parent, args, context) => {
        const { vin } = args
        return context.prisma.vehicle.findUnique({
          where: {
            vin,
          }
        })
      }
   

//询问//

**这个是损坏的，并且有错误：在 prisma.findOneUser 上得到无效值“1”。提供了字符串，预期为 Int **我尝试过这样做id: "1"并且user(where: {id: 1})

query {
  user(id:1){
    id
    fname
  }
}

**这个按预期工作

query {
  vehicle(vin:"123123123"){
    vin
    make
  }
}

//完全错误*//

Prisma 期望Int：

“参数 id：在 prisma.findOneUser 上得到无效值“1”。提供的字符串，预期为 Int。”，

因此你需要转换id为一个数字。也许是这样的：

user: async (parent, args, context) => {
  const id = +args.id;
  return context.prisma.user.findUnique({
    where: { id }
  });
}
