생성된 파일 확인

serverless.yml에 두 개의 함수가 등록되어 있다.

service: helloworld

frameworkVersion: '2'

provider:
  name: azure
  region: West US 2
  runtime: nodejs12

  environment: # these will be created as application settings
    VARIABLE_FOO: 'foo'

plugins: # look for additional plugins in the community plugins repo: https://github.com/serverless/plugins
  - serverless-azure-functions

package:
  exclude:
    - local.settings.json
    - .vscode/**

functions:
  hello:
    handler: src/handlers/hello.sayHello
    events:
      - http: true
        methods:
          - GET
        authLevel: anonymous # can also be `function` or `admin`

  goodbye:
    handler: src/handlers/goodbye.sayGoodbye
    events:
      - http: true
        methods:
          - GET
        authLevel: anonymous

src/handlers/hello.js는 함수의 주체다.

'use strict';

module.exports.sayHello = async function(context, req) {
  context.log('JavaScript HTTP trigger function processed a request.');

  if (req.query.name || (req.body && req.body.name)) {
    context.res = {
      // status: 200, /* Defaults to 200 */
      body: 'Hello ' + (req.query.name || req.body.name),
    };
  } else {
    context.res = {
      status: 400,
      body: 'Please pass a name on the query string or in the request body',
    };
  }
};

로컬 환경에서의 작업 확인

sls offline의 로컬 환경에서 함수 프로그램을 실행해 봅니다.

프로그램 설계

자신의 환경에 여러 프로그램이 있기 때문에 사전에 이 단계 대로 서비스 프린시피를 만들지 않으면 오류가 발생한다.
내가 먼저 드라이런부터 해볼게.

sls invoke도 명령을 통해 직접 호출할 수 있다.

$ sls invoke -f hello -d '{"name":"World"}'

Azure에서 Hello 함수를 프로그래밍할 수 있습니다.
