Function Compute:Kelola resource fungsi menggunakan Serverless Devs

Inisialisasi proyek

sudo s init devsapp/start-fc-http-nodejs14

Contoh ini menerapkan fungsi HTTP dalam Node.js 14. Ganti http dengan tipe pemicu lain seperti event untuk mengubah tipe fungsi. Ganti nodejs14 dengan identifier runtime lain untuk mengubah runtime.

Contoh output:

    Welcome to the Aliyun FC start application
     This application requires to open these services:
         FC : https://fc.console.alibabacloud.com/

     * The project is initialized. You can go to the project directory and run the s deploy command to deploy the project.

 Thanks for using Serverless-Devs
 You could [cd /test/start-fc-http-nodejs14] and enjoy your serverless journey!
 If you need help for this example, you can use [s -h] after you enter folder.

 Do you want to deploy the project immediately? No

Setelah inisialisasi, direktori proyek berisi file-file berikut:

Masuk ke direktori proyek

cd start-fc-http-nodejs14

Bangun proyek (opsional)

Jalankan s build untuk mengompilasi dan mengemas proyek secara lokal:

sudo s build

Perintah ini menghasilkan direktori .s di root proyek yang menyimpan artefak build untuk debugging dan penerapan.

Debug secara lokal (opsional)

Setelah proses build, uji fungsi di mesin Anda sebelum menerapkannya.

Fungsi HTTP:

sudo s local start

Contoh output:

[2021-12-16 07:17:05] [INFO] [FC-LOCAL-INVOKE] - Using trigger for start: name: httpTrigger
type: http
config:
  authType: anonymous
  methods:
    - GET

[2021-12-16 07:17:05] [INFO] [FC-LOCAL-INVOKE] - HttpTrigger httpTrigger of hello-world-service/http-trigger-nodejs14 was registered
        url: http://localhost:7013/2016-08-15/proxy/hello-world-service/http-trigger-nodejs14/
        methods: GET
        authType: anonymous

Tips: You can also use these commands to run or debug custom domain resources:

Start with customDomain:
* s local start auto

Debug with customDomain:
* s local start -d 3000 auto


Tips for next step
======================
* Deploy Resources: s deploy
helloworld:
  status: succeed
function compute app listening on port 7013!

Picu fungsi HTTP dengan cURL atau browser:

curl http://localhost:7013/2016-08-15/proxy/hello-world-service/http-trigger-nodejs14/

Atau buka URL berikut di browser:

http://localhost:7013/2016-08-15/proxy/hello-world-service/http-trigger-nodejs14/

Fungsi event:

sudo s local invoke

Hasil langsung dikembalikan setelah perintah dijalankan.

Terapkan ke Function Compute

sudo s deploy -y

Contoh output:

Checking Service, Function, Triggers (0.82s)
 Creating Service, Function, Triggers (0.6s)
 Creating custom domain (0.31s)

Tips for next step
======================
* Display information of the deployed resource: s info
* Display metrics: s metrics
* Display logs: s logs
* Invoke remote function: s invoke
* Remove Service: s remove service
* Remove Function: s remove function
* Remove Trigger: s remove trigger
* Remove CustomDomain: s remove domain

helloworld:
  region:   cn-hangzhou
  service:
    name: hello-world-service
  function:
    name:       http-trigger-nodejs14

  triggers:
    -
      type: http
      name: httpTrigger

Panggil fungsi secara remote (opsional)

Setelah penerapan, panggil fungsi di cloud untuk memverifikasi fungsinya:

sudo s invoke -e '{"body": "","method":"GET","headers":{"header_1":"v1"},"queries":{"key":"value"},"path":"/"}'

Contoh output:

Request url: https://188077086902****.cn-hangzhou.fc.aliyuncs.com/2016-08-15/proxy/hello-world-service/http-trigger-nodejs14/

}

End of method: invoke

Anda juga dapat memicu fungsi HTTP dengan cURL:

curl https://188077086902****.cn-hangzhou.fc.aliyuncs.com/2016-08-15/proxy/hello-world-service/http-trigger-nodejs14/

Hapus resource (opsional)

Saat Anda tidak lagi memerlukan resource yang telah diterapkan, hapus resource tersebut:

sudo s remove service

Contoh output:

Need to delete the resource in the cn-hangzhou area, the operation service is hello-world-service:
 ......
 Delete trigger hello-world-service/http-trigger-nodejs14/httpTrigger success.
 Delete function hello-world-service/http-trigger-nodejs14 success.
 Delete service hello-world-service success.
