“消息”错误：“禁止”尝试查询 Apollo Serverless Lambda 服务器

Question

我正在尝试遵循此示例，https://www.apollographql.com/docs/apollo-server/deployment/lambda/创建一个无服务器 GraphQL 服务器，该服务器返回“Hello world”。

根目录基本上只包含两个文件，graphql.js以及serverless.yml：

> tree . -I node_modules
.
??? graphql.js
??? package-lock.json
??? package.json
??? serverless.yml

其中，如示例中所示，graphql.js读取

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

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

const resolvers = {
  Query: {
    hello: () => 'Hello world!',
  },
}

const server = new ApolloServer({ typeDefs, resolvers });

exports.graphqlHandler = server.createHandler();

并serverless.yml阅读

service: apollo-lambda

provider:
  name: aws
  runtime: nodejs8.10
functions:
  graphql:
    handler: graphql.graphqlHandler
    events:
      - http:
          path: graphql
          method: post
          cors: true
      - http:
          path: graphql
          method: get
          cors: true

这似乎部署成功：

functions:

Serverless: Run the "serverless" command to setup monitoring, troubleshooting and testing.

但是，如果我去操场并查询“你好”，我会收到一条“禁止”消息：

那是我的

query {
  hello
}

而不是导致在https://www.apollographql.com/docs/apollo-server/essentials/server/记录的响应，导致

{
  "error": {
    "message": "Forbidden"
  }
}

知道我在这里做错了什么吗？

Answer 1

好的，我发现了错误。apollo-server-lamdba 存在一个已知问题。

在浏览Playground 时（在https://e9g6evoks0.execute-api.us-east-1.amazonaws.com/dev/graphql），端点的 url 是预配置的，但它错过了/dev/部分（无服务器中定义的阶段部分） .yml）。只需添加它，这将正常工作。
