AWS Lambda

创建访问密钥

copy Key和Secret，key见下图，secret只有在创建时可见

创建Nodejs项目
app.js

exports.handler = async (event, context) => {
    const response = {
        statusCode: 200,
        headers: {
            'Content-Type': 'text/plain',
        },
        body: 'Hello World\n',
    };
    return response;
};

package.json

{
    "name": "hackernoon",
    "version": "1.0.0",
    "description": "",
    "main": "app.js",
    "scripts": {
        "start": "node app.js"
    },
    "keywords": [],
    "author": "",
    "license": "ISC"
}

serverless.yml

service: my-test

provider:
  name: aws
  runtime: nodejs18.x
  stage: dev
  region: cn-northwest-1

functions:
  hello:
    handler: app.handler
    events:
      - http:
          path: hello
          method: get

npm install -g serverless

cd到项目文件夹下，执行以下命令
serverless config credentials --provider aws --key --secret

执行完成后可在个人路径下见到.aws/credentials文件

执行serverless deploy

出现错误：

原因是APIGateway默认用Edge（边缘计算），但region：cn-northwest-1不支持Edge模式，所以，修改 serverless.yml，增加 endpointType: REGIONAL

service: my-test

provider:
  name: aws
  endpointType: REGIONAL
  runtime: nodejs18.x
  stage: dev
  region: cn-northwest-1

functions:
  hello:
    handler: app.handler
    events:
      - http:
          path: hello
          method: get

再次执行serverless deploy,部署成功

查看APIGateway，多出了一条记录
