如何在无服务器框架中设置路由

Question

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

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

生成如下目录

.
├── 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
│   │   │   └── schema.ts       # `Hello` lambda input event JSON-Schema

└── webpack.config.js           # Webpack configuration

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);

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                                │

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

我的问题是

①如何在各个功能中设置路由?例如，我想在我的项目中添加GET函数。我找不到如何在我的函数中设置路由。

hello/handler.ts中POST

的定义在哪里?②如何改变环境?似乎离线从dev阶段(us-east-1)开始，我该如何改变这个阶段?是否需要设置?

如果有人有意见或材料，请告诉我。由于

感谢

对于get请求，仍然可以使用相同的函数签名。

就这样写get request:

const getFunc: ValidatedEventAPIGatewayProxyEvent<typeof undefined> = async (event) => {
//Your function logic goes in here
return formatJSONResponse({
message: `Hello, welcome to the exciting Serverless world!`,

});
};

PS:当启动一个get请求时，不需要一个body request属性，根据我的理解，它是针对模式进行验证的;因此，您可以为模式类型指定undefined。
