GraphQL lambda解析器返回未经授权的访问

const { ApolloServer, gql } = require('apollo-server-lambda');

// 定义Schema
const typeDefs = gql`
  type Query {
    hello: String
  }
`;

// 定义解析器
const resolvers = {
  Query: {
    hello: (_, __, context) => {
      // 检查认证信息
      if (!context.user) {
        throw new Error('Unauthorized');
      }
      return 'Hello, world!';
    }
  }
};

// 创建Apollo Server实例
const server = new ApolloServer({
  typeDefs,
  resolvers,
  context: ({ event, context }) => ({
    headers: event.headers,
    functionName: context.functionName,
    event,
    context,
    user: event.headers.Authorization ? event.headers.Authorization.split(' ')[1] : null
  })
});

// 导出Lambda处理函数
exports.graphqlHandler = server.createHandler();
