【中文标题】“消息”错误：“禁止”尝试查询 Apollo Serverless Lambda 服务器

【英文标题】：Error with "message": "Forbidden" trying to query an Apollo Serverless Lambda server

【问题描述】：

我正在尝试按照这个示例 https://www.apollographql.com/docs/apollo-server/deployment/lambda/ 创建一个返回“Hello world”的无服务器 GraphQL 服务器。

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

> tree . -I node_modules
.
├── graphql.js
├── package-lock.json
├── package.json
└── serverless.yml

在哪里，如示例中，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();

和serverless.yml 读取

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：

Service Information
service: apollo-lambda

functions:
  graphql: apollo-lambda-dev-graphql

  None
Serverless: Run the "serverless" command to setup monitoring, troubleshooting and testing.

但是，如果我去操场查询“你好”，我会收到一条“禁止”消息：

也就是说，我的

query 
  hello

而不是产生记录在https://www.apollographql.com/docs/apollo-server/essentials/server/ 的响应，而是产生一个

  "error": 
    "message": "Forbidden"
  

知道我在这里做错了什么吗？

【参考方案1】：

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

在浏览 Playground（https://e9g6evoks0.execute-api.us-east-1.amazonaws.com/dev/graphql）时，端点的 url 已预先归档，但它错过了 /dev/ 部分（在 serverless.yml 中定义的阶段部分）。只需添加它就可以了。

【讨论】：

我仍然缺少一些东西。你做了什么来解决这个问题？

即使在添加舞台开发后我也面临同样的问题。有什么建议吗？

【参考方案2】：

其实原教程已经有了解决方案（Setting up GraphQL Playground）。只需如下编辑您的代码。

const server = new ApolloServer( 
    typeDefs, 
    resolvers, 
    playground: 
        endpoint: "/dev/graphql"
    
);
