带有args的graphql查询不适用于用户ID

问题描述

我被骗了。我最初创建了用户查询，它给了我错误，我认为是语法错误。但是后来我为车辆创建了一个完全相同的查询。我怀疑跟身份证有关！类型，但我的线索用完了。任何帮助将不胜感激！

这是我的 typedef 和解析器。

//TYPEDEFS//

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

//查询//

**这个是坏掉的并且有错误：在prisma.findOneUser 上得到无效值'1'。提供的字符串，预期的 Int **我试过 id: "1" 和 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*//

解决方法

Prisma 需要一个 Int：

"参数 ID：在prisma.findOneUser 上得到无效值'1'。提供 字符串，预期为整数。",

因此您需要将 id 转换为数字。也许是这样的：

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