Question

我需要一些帮助来解决graphql上的错误，在这种情况下我什么都找不到。

我试图将我的不同架构和解析器分开以使其易于维护，但是当我使用makeExecutableSchema函数（来自graphql-tools程序包）时，抛出“ GraphQLError：语法错误：意外的名称“ User””错误。

这是错误：

/Users/thomasblanquet/EIP_Routs/API/routs-api/node_modules/graphql/language/parser.js:153
  throw unexpected(lexer);
  ^

这是我的代码：

对于用户架构：

const User = `
User {
  _id: Int!
  username: String!
  email: String!
}

extend type Query {
    users: [User]
}
`;

module.exports = User;

对于解析器（该模型是使用sequelize创建的，而我正在使用Apollo-Server-Express）：

const User = require('../../server/models/user')
const Messages = require('../messages');

const resolvers = {
  Query: {
    users(parent, args, context, info) {
      parent.getUsers()
    },
};

module.exports = resolvers;

最后是将架构和解析器组合在一起的代码：

const { makeExecutableSchema } = require('graphql-tools');
const resolvers = require('./resolver');
const User = require('./user/schema');

const Query =
`type Query {
  _empty: String
}`;

const Mutation =
`type Mutation {
  _empty: String
}`;

module.exports = makeExecutableSchema({
  typeDefs: [Query, Mutation, User],
  resolvers,
});

对于这种问题，我真的找不到任何东西，谢谢您的帮助：）

Answer 1

您看到此错误，是因为您在用户类型定义中未使用type关键字。应该是：

type User {
  _id: Int!
  username: String!
  email: String!
}

还请注意，您的解析器正在根对象上调用getUsers，这也可能会崩溃（我想您打算使用模型来代替）。

makeExecutableSchema的语法错误：意外的名称“用户”（GraphQL）
