如何在Localstack中部署搭载GraphQL的NestJS Serverless Lambda服务

我已经找到了解决方案，感谢大家的时间。StackOverflow不允许我自行回答问题 >:(

我想了解如何配置才能将搭载GraphQL而非RestApi的NestJS应用部署为Localstack的Lambda服务，以下是我目前的配置：

• 当前配置是否正确？
• 如何获取模拟访问链接，通过Localstack Lambda访问GraphQL Playground？

NestJS Lambda函数项目配置 #

import { ValidationPipe } from '@nestjs/common';
import { NestFactory } from '@nestjs/core';
import { ExpressAdapter } from '@nestjs/platform-express';
import serverlessExpress from '@vendia/serverless-express';
import { APIGatewayProxyHandler, Handler } from 'aws-lambda';
import express from 'express';
import { AppModule } from './app.module';

let cachedServer: Handler;

const bootstrapServer = async (): Promise<Handler> => {
  const expressApp = express();
  const app = await NestFactory.create(
    AppModule,
    new ExpressAdapter(expressApp),
  );
  app.useGlobalPipes(new ValidationPipe());
  app.enableCors();
  await app.init();
  return serverlessExpress({
    app: expressApp,
  });
};

export const handler: APIGatewayProxyHandler = async (
  event,
  context,
  callback,
) => {
  if (!cachedServer) {
    cachedServer = await bootstrapServer();
  }
  return cachedServer(event, context, callback);
};

Serverless.yml 配置 #

service: test

provider:
  name: aws
  runtime: nodejs14.x
  stage: ''
  # profile: local # 配置你的AWS Profile
  environment: # 服务全局环境变量
    NODE_ENV: local
    GLOBAL_PREFIX: graphql
    PORT: 4000

plugins:
#  - serverless-plugin-typescript
#  - serverless-plugin-optimize
#  - serverless-offline
 - serverless-localstack

custom:
  localstack:
    debug: true
    stages:
     - local
     - dev
    endpointFile: localstack_endpoints.json
    individually: true
  # serverless-offline:
  #   httpPort: 3000
    
functions:
 main:
   handler: dis/index.handler

#  local:
#    handler: dist/main.handler
#    events:
#      - http:
#           path: /
#           method: any
#           cors: true

Docker Compose Localstack 配置 #

version: '3.8'

services: 
  localstack:
    image: localstack/localstack:latest
    environment: 
      - AWS_DEFAULT_REGION=us-east-1
      - EDGE_PORT=4566
      - SERVICES=lambda,s3,cloudformation,sts
    ports: 
      - '4566-4597:4566-4597'
    volumes: 
      - "${TMPDIR:-/tmp}/localstack:/tmp/localstack"
      - "/var/run/docker.sock:/var/run/docker.sock"

服务端点配置 #

{
    "CloudFormation" : "http://localhost:4566",
    "CloudWatch" : "http://localhost:4566",
    "Lambda" : "http://localhost:4566",
    "S3" : "http://localhost:4566"
}

执行命令 #

执行serverless deploy --stage local命令时出现报错
执行serverless info --stage local命令时返回对应信息
执行serverless invoke local -f main -l命令时返回对应结果
