Membuat dan men-deploy fungsi Cloud Run HTTP menggunakan Go (generasi ke-1)
Panduan ini akan memandu Anda dalam proses penulisan fungsi Cloud Run menggunakan runtime Go. Ada dua jenis fungsi Cloud Run:
Fungsi HTTP, yang Anda panggil dari permintaan HTTP standar.
Fungsi berbasis peristiwa, yang Anda gunakan untuk menangani peristiwa dari infrastruktur Cloud, seperti pesan di topik Pub/Sub, atau perubahan dalam bucket Cloud Storage.
Contoh ini menunjukkan cara membuat fungsi HTTP sederhana.
Sebelum memulai

In the Google Cloud console, on the project selector page,
select or create a Google Cloud project.
Buat direktori di sistem lokal Anda untuk kode fungsi:
Linux atau Mac OS X
mkdir ~/helloworld
cd ~/helloworld
Windows
mkdir %HOMEPATH%\helloworld
cd %HOMEPATH%\helloworld
Buat file bernama hello_http.go di direktori helloworld dengan konten berikut:
// Package helloworld provides a set of Cloud Functions samples.packagehelloworldimport("encoding/json""fmt""html""net/http""github.com/GoogleCloudPlatform/functions-framework-go/functions")funcinit(){functions.HTTP("HelloHTTP",HelloHTTP)}// HelloHTTP is an HTTP Cloud Function with a request parameter.funcHelloHTTP(whttp.ResponseWriter,r*http.Request){vardstruct{Namestring`json:"name"`}iferr:=json.NewDecoder(r.Body).Decode(&d);err!=nil{fmt.Fprint(w,"Hello, World!")return}ifd.Name==""{fmt.Fprint(w,"Hello, World!")return}fmt.Fprintf(w,"Hello, %s!",html.EscapeString(d.Name))}
Fungsi contoh ini mengambil nama yang diberikan dalam permintaan HTTP dan menampilkan salam, atau "Halo Dunia!" jika tidak ada nama yang diberikan.
Menentukan dependensi
Fungsi contoh ini hanya menggunakan paket library standar Go, sehingga Anda tidak perlu mendeklarasikan dependensi apa pun selain mengimpor paket.
Untuk fungsi yang memerlukan dependensi di luar library standar, Anda harus menyediakan dependensi melalui file go.mod atau direktori vendor. Untuk detail selengkapnya, baca
Menentukan dependensi di Go.
Men-deploy fungsi
Untuk men-deploy fungsi dengan pemicu HTTP, jalankan perintah berikut di direktori helloworld, yang menentukan go113 atau go111 sebagai nilai untuk flag --runtime, bergantung pada versi yang Anda
gunakan:

There are two types of Cloud Run functions:\n\n- An HTTP function, which you invoke from standard HTTP requests.\n- An event-driven function, which you use to handle events from your Cloud infrastructure, such as messages on a Pub/Sub topic, or changes in a Cloud Storage bucket.\n\nThe sample shows how to create a simple HTTP function.\n| **Learn more** : For more details, read about [HTTP functions](/functions/1stgendocs/writing/write-http-functions) and [event-driven functions](/functions/1stgendocs/writing/write-event-driven-functions).\n\nBefore you begin\n----------------\n\n- Sign in to your Google Cloud account.

[Install and initialize the gcloud CLI](/sdk/docs).\n2. Update and install `gcloud` components: \n\n ```bash\n gcloud components update\n ```\n| **Note** : Need a command prompt? You can use the [Google Cloud\n| Shell](https://console.cloud.google.com/?cloudshell=true). The Google Cloud Shell is a command line environment that already includes the Google Cloud CLI, so you don't need to install it. The Google Cloud CLI also comes preinstalled on Google Compute Engine Virtual Machines.\n3. Prepare your development environment.\n [Go to the Go setup guide](/go/docs/setup)\n\nCreate a function\n-----------------\n\n1. Create a directory on your local system for the function code:\n\n ### Linux or Mac OS X\n\n mkdir ~/helloworld\n cd ~/helloworld\n\n ### Windows\n\n mkdir %HOMEPATH%\\helloworld\n cd %HOMEPATH%\\helloworld\n\n2. Create a file called `hello_http.go` in the `helloworld`\n directory with the following contents:\n\n\n // Package helloworld provides a set of Cloud Functions samples.\n package helloworld\n\n import (\n \t\"encoding/json\"\n \t\"fmt\"\n \t\"html\"\n \t\"net/http\"\n\n \t\"github.com/GoogleCloudPlatform/functions-framework-go/functions\"\n )\n\n func init() {\n \tfunctions.HTTP(\"HelloHTTP\", HelloHTTP)\n }\n\n // HelloHTTP is an HTTP Cloud Function with a request parameter.\n func HelloHTTP(w http.ResponseWriter, r *http.Request) {\n \tvar d struct {\n \t\tName string `json:\"name\"`\n \t}\n \tif err := json.NewDecoder(r.Body).Decode(&d); err != nil {\n \t\tfmt.Fprint(w, \"Hello, World!\")\n \t\treturn\n \t}\n \tif d.Name == \"\" {\n \t\tfmt.Fprint(w, \"Hello, World!\")\n \t\treturn\n \t}\n \tfmt.Fprintf(w, \"Hello, %s!\", html.EscapeString(d.Name))\n }\n\n This example function takes a name supplied in the HTTP request and returns\n a greeting, or \"Hello, World!\" when no name is supplied.\n\nSpecify dependencies\n--------------------\n\nThis example function only uses Go standard library packages, so you don't need\nto declare any dependencies beyond just importing the packages.\n\nFor functions that require dependencies outside of the standard library,\nyou must provide the dependencies via either a `go.mod` file or a `vendor`\ndirectory. For more details, read\n[Specifying dependencies in Go](/functions/1stgendocs/writing/specifying-dependencies-go).\n\nDeploy the function\n-------------------\n\nTo deploy the function with an HTTP trigger, run the following\ncommand in the `helloworld` directory, specifying either `go113` or\n`go111` as the value for the `--runtime` flag, depending on which version you\nare using: \n\n```sh\ngcloud functions deploy HelloHTTP --no-gen2 --runtime go121 --trigger-http --allow-unauthenticated\n```\n| **Note:** Cloud Run functions looks for deployable functions in your terminal's current directory by default. Use the [`--source`](/sdk/gcloud/reference/functions/deploy#--source) flag when [deploying your function via `gcloud`](#deploying_the_function) to specify a different function source directory.\n\nThe `--allow-unauthenticated` flag lets you reach the function\n[without authentication](/functions/1stgendocs/securing/managing-access-iam#allowing_unauthenticated_http_function_invocation).\nTo require\n[authentication](/functions/1stgendocs/securing/authenticating#developers), omit the\nflag.\n| **Learn more** : For more details, read about [deploying Cloud Run functions](/functions/1stgendocs/deploy#basics).\n\nTest the function\n-----------------\n\n1. When the function finishes deploying, take note of the `httpsTrigger.url`\n property or find it using the following command:\n\n gcloud functions describe HelloHTTP\n\n It should look like this: \n\n ```\n https://GCP_REGION-PROJECT_ID.cloudfunctions.net/HelloHTTP\n ```\n2. Visit this URL in your browser, or use cURL by running the command:\n\n ```sh\n curl https://GCP_REGION-PROJECT_ID.cloudfunctions.net/HelloHTTP\n ```\n\n You should see a \"Hello, World!\" message. Try passing a name\n in the HTTP request by running the following command: \n\n ```sh\n curl -X POST https://GCP_REGION-PROJECT_ID.cloudfunctions.net/HelloHTTP -H \"Content-Type:application/json\" -d '{\"name\":\"NAME\"}'\n ```\n\n You should see the message \"Hello, \u003cvar translate=\"no\"\u003eNAME\u003c/var\u003e!\"\n\nView logs\n---------\n\nLogs for Cloud Run functions are viewable using the Google Cloud CLI, and in the\nCloud Logging UI.\n\n### Use the command-line tool\n\nTo view logs for your function with the gcloud CLI, use the\n[`logs read`](/sdk/gcloud/reference/functions/logs/read) command, followed by\nthe name of the function: \n\n```bash\ngcloud functions logs read HelloHTTP\n```\n\nThe output should resemble the following: \n\n```bash\nLEVEL NAME EXECUTION_ID TIME_UTC LOG\nD HelloHTTP buv9ej2k1a7r 2019-09-20 13:23:18.910 Function execution started\nD HelloHTTP buv9ej2k1a7r 2019-09-20 13:23:18.913 Function execution took 4 ms, finished with status code: 200\n```\n| **Note:** There is typically a slight delay between when log entries are created and when they show up in Cloud Logging.\n\n### Use the Logging dashboard\n\nYou can also view logs for Cloud Run functions from the\n[Google Cloud console](https://console.cloud.google.com/project/_/logs?service=cloudfunctions.googleapis.com).\n| **Learn more** : For more details, read about [writing, viewing, and responding to logs](/functions/1stgendocs/monitoring/logging)."]]
