来自 apollo-server-lambda 上下文的 `express` object 未定义

Question

我正在关注 this guide 使我的 apollo 服务器运行具有 Netlify 功能。它适用于未经身份验证的请求，但当我需要阅读 headers.

时遇到问题

指南说我可以从 express object 中获取 req，如该片段所示。

const server = new ApolloServer({
  typeDefs,
  resolvers,
  context: ({ event, context, express }) => ({
    headers: event.headers,
    functionName: context.functionName,
    event,
    context,
    expressRequest: express.req,
  }),
});

然而，当我自己尝试这个时，我得到了一个未定义的 express。这是我的代码。

const { ApolloServer } = require("apollo-server-lambda");
const accountsGraphQL = require("./accounts.js");
const schema = require("./schema/index.js");

const server = new ApolloServer({
  schema,
  context: async ({ event, context, express }) => {
    console.log(express); // outputs undefined
    return {
      headers: event.headers,
      functionName: context.functionName,
      event,
      context: await accountsGraphQL.context(express.req), // errors `Context creation failed: Cannot read property 'req' of undefined`
    }
  },
  introspection: true,
  playground: true,
});

const handler = server.createHandler();

module.exports = { handler };

无论如何，我通过制作另一个包含 req 和 headers 和 authorization 的对象解决了我的问题。

const { ApolloServer } = require("apollo-server-lambda");
const accountsGraphQL = require("./accounts.js");
const schema = require("./schema/index.js");

const server = new ApolloServer({
  schema,
  context: async ({ event }) => {
    return await accountsGraphQL.context({
      req: { headers: { authorization: event.headers.authorization } },
    });
  },
  introspection: true,
  playground: true,
});

const handler = server.createHandler();

module.exports = { handler };
