3. Lihat kode contoh:

   Node.js

   const functions = require('@google-cloud/functions-framework');
   
   // Register an HTTP function with the Functions Framework that will be executed
   // when you make an HTTP request to the deployed function's endpoint.
   functions.http('helloGET', (req, res) => {
     res.send('Hello World!');
   });

   Python

   import functions_framework
   
   @functions_framework.http
   def hello_get(request):
       """HTTP Cloud Function.
       Args:
           request (flask.Request): The request object.
           <https://flask.palletsprojects.com/en/1.1.x/api/#incoming-request-data>
       Returns:
           The response text, or any set of values that can be turned into a
           Response object using `make_response`
           <https://flask.palletsprojects.com/en/1.1.x/api/#flask.make_response>.
       Note:
           For more information on how Flask integrates with Cloud
           Functions, see the `Writing HTTP functions` page.
           <https://cloud.google.com/functions/docs/writing/http#http_frameworks>
       """
       return "Hello World!"
   

   Go

   
   // Package helloworld provides a set of Cloud Functions samples.
   package helloworld
   
   import (
   	"fmt"
   	"net/http"
   )
   
   // HelloGet is an HTTP Cloud Function.
   func HelloGet(w http.ResponseWriter, r *http.Request) {
   	fmt.Fprint(w, "Hello, World!")
   }
   

   Java

   
   package functions;
   
   import com.google.cloud.functions.HttpFunction;
   import com.google.cloud.functions.HttpRequest;
   import com.google.cloud.functions.HttpResponse;
   import java.io.BufferedWriter;
   import java.io.IOException;
   
   public class HelloWorld implements HttpFunction {
     // Simple function to return "Hello World"
     @Override
     public void service(HttpRequest request, HttpResponse response)
         throws IOException {
       BufferedWriter writer = response.getWriter();
       writer.write("Hello World!");
     }
   }

   C#

   using Google.Cloud.Functions.Framework;
   using Microsoft.AspNetCore.Http;
   using System.Threading.Tasks;
   
   namespace HelloWorld;
   
   public class Function : IHttpFunction
   {
       public async Task HandleAsync(HttpContext context)
       {
           await context.Response.WriteAsync("Hello World!", context.RequestAborted);
       }
   }

   Ruby

   require "functions_framework"
   
   FunctionsFramework.http "hello_get" do |_request|
     # The request parameter is a Rack::Request object.
     # See https://www.rubydoc.info/gems/rack/Rack/Request
   
     # Return the response body as a string.
     # You can also return a Rack::Response object, a Rack response array, or
     # a hash which will be JSON-encoded into a response.
     "Hello World!"
   end

   PHP

   
   use Psr\Http\Message\ServerRequestInterface;
   
   function helloGet(ServerRequestInterface $request): string
   {
       return 'Hello, World!' . PHP_EOL;
   }
   

Men-deploy fungsi

Untuk men-deploy fungsi dengan pemicu HTTP, jalankan perintah berikut di direktori yang berisi fungsi Anda:

gcloud functions deploy helloGET \
--runtime nodejs20 --trigger-http

gcloud functions deploy hello_get \
--runtime python312 --trigger-http

gcloud functions deploy HelloGet \
--runtime go121 --trigger-http

gcloud functions deploy java-helloworld \
--entry-point functions.HelloWorld \
--runtime java17 \
--memory 512MB --trigger-http

gcloud functions deploy csharp-helloworld \
--entry-point HelloWorld.Function \
--runtime dotnet6 --trigger-http

gcloud functions deploy hello_get --runtime ruby32 --trigger-http

 gcloud functions deploy helloGet --runtime php82 --trigger-http

Secara opsional, Anda dapat menggunakan flag --allow-unauthenticated untuk menjangkau fungsi tanpa autentikasi. Hal ini berguna untuk pengujian, tetapi sebaiknya jangan gunakan setelan ini dalam produksi kecuali Anda membuat situs atau API publik. Selain itu, fitur ini mungkin tidak berfungsi untuk Anda, bergantung pada setelan kebijakan perusahaan Anda. Baca bagian Mengautentikasi pemanggilan untuk mengetahui informasi selengkapnya tentang cara memanggil fungsi yang memerlukan autentikasi.

Menguji fungsi

1. Setelah fungsi selesai di-deploy, catat properti httpsTrigger url atau temukan menggunakan perintah berikut:

   Node.js

   gcloud functions describe helloGET --format="value(httpsTrigger.url)"

   Python

   gcloud functions describe hello_get --format="value(httpsTrigger.url)"

   Go

   gcloud functions describe HelloGet --format="value(httpsTrigger.url)"

   Java

   gcloud functions describe java-helloworld --format="value(httpsTrigger.url)"

   C#

   gcloud functions describe csharp-helloworld --format="value(httpsTrigger.url)"

   Ruby

   gcloud functions describe hello_get --format="value(httpsTrigger.url)"

   PHP

   gcloud functions describe helloGet --format="value(httpsTrigger.url)"

   Kodenya akan terlihat seperti berikut:

   Node.js

   https://GCP_REGION-PROJECT_ID.cloudfunctions.net/helloGET

   Python

   https://GCP_REGION-PROJECT_ID.cloudfunctions.net/hello_get

   Go

   https://GCP_REGION-PROJECT_ID.cloudfunctions.net/HelloGet

   Java

   https://GCP_REGION-PROJECT_ID.cloudfunctions.net/java-helloworld

   C#

   https://GCP_REGION-PROJECT_ID.cloudfunctions.net/csharp-helloworld

   Ruby

   https://GCP_REGION-PROJECT_ID.cloudfunctions.net/hello_get

   PHP

   https://GCP_REGION-PROJECT_ID.cloudfunctions.net/helloGet

2. Kunjungi URL ini di browser Anda. Anda akan melihat pesan Hello World!.

Hapus fungsi

Untuk menghapus fungsi, jalankan perintah berikut:

gcloud functions delete helloGET 

gcloud functions delete hello_get 

gcloud functions delete HelloGet 

gcloud functions delete java-helloworld 

gcloud functions delete csharp-helloworld 

gcloud functions delete hello_get 

gcloud functions delete helloGet
