如何在无服务器框架中设置路由

Question

我想通过使用serverless-framework开发示例应用程序及其路由。我发出以下命令

sls create -t aws-nodejs-typescript -n sample-api-dev

它生成以下目录

.
├── src
│   ├── functions               # Lambda configuration and source code folder
│   │   ├── hello
│   │   │   ├── handler.ts      # `Hello` lambda source code
│   │   │   ├── index.ts        # `Hello` lambda Serverless configuration
│   │   │   ├── mock.json       # `Hello` lambda input parameter, if any, for local invocation

handler.ts

import type { ValidatedEventAPIGatewayProxyEvent } from '@libs/api-gateway';
import { formatJSONResponse } from '@libs/api-gateway';
import { middyfy } from '@libs/lambda';

import schema from './schema';

const hello: ValidatedEventAPIGatewayProxyEvent<typeof schema> = async (event) => {
  return formatJSONResponse({
    message: `Hello ${event.body.name}, welcome to the exciting Serverless world!`,
    event,
  });
};

export const main = middyfy(hello);

在此之后，我发送以下命令

sls local start

MAC0157:$ sls offline start
Running "serverless" from node_modules

Starting Offline at stage dev (us-east-1)

Offline [http for lambda] listening on http://localhost:3002

   │   POST | http://localhost:3000/dev/hello                                │

   └─────────────────────────────────────────────────────────────────────────┘

Server ready: http://localhost:3000 

我的问题是

如何在每个函数中设置路由？例如，我想在我的项目中添加GET函数，我找不到如何在function.Where中设置路由，POST是在hello/handler.ts中定义的吗？

2如何改变环境？似乎离线开始在舞台开发(美-东-1)，我如何改变这个阶段？需要设置什么环境吗？

如果有人有意见或资料，请告诉我。谢谢

谢谢

对于get请求，仍然可以使用相同的函数签名。

只需按此方式为get请求编写：

const getFunc: ValidatedEventAPIGatewayProxyEvent<typeof undefined> = async (event) => {

//Your function logic goes in here

  return formatJSONResponse({
    message: `Hello, welcome to the exciting Serverless world!`,
    
  });
};

PS:在启动get请求时，不需要根据模式验证body request属性；因此，您只需为模式类型指定未定义的属性。
