我正在尝试使用 Apollo Server 开发后端，我在浏览器中启用了 cors 并尝试cors: {origin: true}在服务器中添加配置。我已经在下面包含了服务器代码。

希望有人能够发现我搞砸了什么。

// index.js
const {ApolloServer} = require('apollo-server')
const typeDefs = require('./schema')
const resolvers = require('./resolvers')
const CourseAPI = require('./sources')

const apollo = new ApolloServer({
  typeDefs,
  resolvers,
  cors: {
    origin: true
  },
  dataSources: () => {
    return {
      courseAPI: new CourseAPI({
        client: 'pg',
        connection: {
          host: 'ec2-79-125-30-28.eu-west-1.compute.amazonaws.com',
          user: 'hgsfclebwdvtrz',
          password:
            '975260d79ace6b3f78132e6d51f8f56612e6cbc24c8d6063b9c6be60f5160453',
          database: 'd7jasm9tcmpc30'
        }
      })
    }
  }
})

apollo.listen().then(({url}) => {
  console.log(` Server ready at ${url}`)
})
