# Contoh kode untuk Lambda menggunakan AWS SDKs
<a name="service_code_examples"></a>

Contoh kode berikut menunjukkan cara menggunakan Lambda dengan kit pengembangan AWS perangkat lunak (SDK). 

*Dasar-dasar* adalah contoh kode yang menunjukkan kepada Anda bagaimana melakukan operasi penting dalam suatu layanan.

*Tindakan* merupakan kutipan kode dari program yang lebih besar dan harus dijalankan dalam konteks. Sementara tindakan menunjukkan cara memanggil fungsi layanan individual, Anda dapat melihat tindakan dalam konteks dalam skenario terkait.

*Skenario* adalah contoh kode yang menunjukkan kepada Anda bagaimana menyelesaikan tugas tertentu dengan memanggil beberapa fungsi dalam layanan atau dikombinasikan dengan yang lain Layanan AWS.

*AWS kontribusi komunitas* adalah contoh yang dibuat dan dikelola oleh banyak tim AWS. Untuk memberikan umpan balik, gunakan mekanisme yang disediakan di repositori terkait.

Untuk daftar lengkap panduan pengembang AWS SDK dan contoh kode, lihat[Menggunakan Lambda dengan SDK AWS](sdk-general-information-section.md). Topik ini juga mencakup informasi tentang memulai dan detail tentang versi SDK sebelumnya.

#### [ JavaScript ]

**SDK untuk JavaScript (v3)**  
 Ada lebih banyak tentang GitHub. Temukan contoh lengkapnya dan pelajari cara mengatur dan menjalankannya di [Repositori Contoh Kode AWS](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javascriptv3/example_code/lambda/scenarios/basic#code-examples). 
Buat peran AWS Identity and Access Management (IAM) yang memberikan izin Lambda untuk menulis ke log.  

```
    logger.log(`Creating role (${NAME_ROLE_LAMBDA})...`);
    const response = await createRole(NAME_ROLE_LAMBDA);

import { AttachRolePolicyCommand, IAMClient } from "@aws-sdk/client-iam";

const client = new IAMClient({});

/**
 *
 * @param {string} policyArn
 * @param {string} roleName
 */
export const attachRolePolicy = (policyArn, roleName) => {
  const command = new AttachRolePolicyCommand({
    PolicyArn: policyArn,
    RoleName: roleName,
  });

  return client.send(command);
};
```
Buat fungsi Lambda dan unggah kode handler.  

```
const createFunction = async (funcName, roleArn) => {
  const client = new LambdaClient({});
  const code = await readFile(`${dirname}../functions/${funcName}.zip`);

  const command = new CreateFunctionCommand({
    Code: { ZipFile: code },
    FunctionName: funcName,
    Role: roleArn,
    Architectures: [Architecture.arm64],
    Handler: "index.handler", // Required when sending a .zip file
    PackageType: PackageType.Zip, // Required when sending a .zip file
    Runtime: Runtime.nodejs16x, // Required when sending a .zip file
  });

  return client.send(command);
};
```
Panggil fungsi dengan satu parameter dan dapatkan hasil.  

```
const invoke = async (funcName, payload) => {
  const client = new LambdaClient({});
  const command = new InvokeCommand({
    FunctionName: funcName,
    Payload: JSON.stringify(payload),
    LogType: LogType.Tail,
  });

  const { Payload, LogResult } = await client.send(command);
  const result = Buffer.from(Payload).toString();
  const logs = Buffer.from(LogResult, "base64").toString();
  return { logs, result };
};
```
Perbarui kode fungsi dan konfigurasikan lingkungan Lambda dengan variabel lingkungan.  

```
const updateFunctionCode = async (funcName, newFunc) => {
  const client = new LambdaClient({});
  const code = await readFile(`${dirname}../functions/${newFunc}.zip`);
  const command = new UpdateFunctionCodeCommand({
    ZipFile: code,

## Service actions

Service actions wrap the SDK call, taking a client and any specific parameters necessary for the call.

* CreateFunction
* GetFunction
* ListFunctions
* Invoke
* UpdateFunctionCode
* UpdateFunctionConfiguration
* DeleteFunction

## Scenario
A scenario runs at a command prompt and prints output to the user on the result of each service action. A scenario can run in one of two ways: straight through, printing out progress as it goes, or as an interactive question/answer script.

## Getting started with functions

Use an SDK to manage AWS Lambda functions: create a function, invoke it, update its code, invoke it again, view its output and logs, and delete it.

This scenario uses two Lambda handlers:
_Note: Handlers don't use AWS SDK API calls._

The increment handler is straightforward:

1. It accepts a number, increments it, and returns the new value.
2. It performs simple logging of the result.

The arithmetic handler is more complex:
1. It accepts a set of actions ['plus', 'minus', 'times', 'divided-by'] and two numbers, and returns the result of the calculation.
2. It uses an environment variable to control log level (such as DEBUG, INFO, WARNING, ERROR).
It logs a few things at different levels, such as:
    * DEBUG: Full event data.
    * INFO: The calculation result.
    * WARN~ING~: When a divide by zero error occurs.
    * This will be the typical `RUST_LOG` variable.


The steps of the scenario are:

1. Create an AWS Identity and Access Management (IAM) role that meets the following requirements:
    * Has an assume_role policy that grants 'lambda.amazonaws.com' the 'sts:AssumeRole' action.
    * Attaches the 'arn:aws:iam::aws:policy/service-role/AWSLambdaBasicExecutionRole' managed role.
    * _You must wait for ~10 seconds after the role is created before you can use it!_
2. Create a function (CreateFunction) for the increment handler by packaging it as a zip and doing one of the following:
    * Adding it with CreateFunction Code.ZipFile.
    * --or--
    * Uploading it to Amazon Simple Storage Service (Amazon S3) and adding it with CreateFunction Code.S3Bucket/S3Key.
    * _Note: Zipping the file does not have to be done in code._
    * If you have a waiter, use it to wait until the function is active. Otherwise, call GetFunction until State is Active.
3. Invoke the function with a number and print the result.
4. Update the function (UpdateFunctionCode) to the arithmetic handler by packaging it as a zip and doing one of the following:
    * Adding it with UpdateFunctionCode ZipFile.
    * --or--
    * Uploading it to Amazon S3 and adding it with UpdateFunctionCode S3Bucket/S3Key.
5. Call GetFunction until Configuration.LastUpdateStatus is 'Successful' (or 'Failed').
6. Update the environment variable by calling UpdateFunctionConfiguration and pass it a log level, such as:
    * Environment={'Variables': {'RUST_LOG': 'TRACE'}}
7. Invoke the function with an action from the list and a couple of values. Include LogType='Tail' to get logs in the result. Print the result of the calculation and the log.
8. [Optional] Invoke the function to provoke a divide-by-zero error and show the log result.
9. List all functions for the account, using pagination (ListFunctions).
10. Delete the function (DeleteFunction).
11. Delete the role.

Each step should use the function created in Service Actions to abstract calling the SDK.

# Gunakan `CreateAlias` dengan CLI
<a name="example_lambda_CreateAlias_section"></a>

Contoh kode berikut menunjukkan cara menggunakan`CreateAlias`.

------
#### [ CLI ]

**AWS CLI**  
**Untuk membuat alias untuk fungsi Lambda**  
`create-alias`Contoh berikut membuat alias bernama `LIVE` yang menunjuk ke versi 1 dari fungsi `my-function` Lambda.  

```
aws lambda create-alias \
    --function-name my-function \
    --description "alias for live version of function" \
    --function-version 1 \
    --name LIVE
```
Output:  

```
{
    "FunctionVersion": "1",
    "Name": "LIVE",
    "AliasArn": "arn:aws:lambda:us-west-2:123456789012:function:my-function:LIVE",
    "RevisionId": "873282ed-4cd3-4dc8-a069-d0c647e470c6",
    "Description": "alias for live version of function"
}
```
Untuk informasi selengkapnya, lihat [Mengonfigurasi Alias Fungsi AWS Lambda](https://docs.aws.amazon.com/lambda/latest/dg/aliases-intro.html) di Panduan Pengembang *AWS Lambda*.

------
#### [ PowerShell ]

**Alat untuk PowerShell V4**  
**Contoh 1: Contoh ini membuat Alias Lambda Baru untuk versi tertentu dan konfigurasi perutean untuk menentukan persentase permintaan pemanggilan yang diterimanya.**  

```
New-LMAlias -FunctionName "MylambdaFunction123" -RoutingConfig_AdditionalVersionWeight @{Name="1";Value="0.6} -Description "Alias for version 4" -FunctionVersion 4 -Name "PowershellAlias"
```
+  Untuk detail API, lihat [CreateAlias](https://docs.aws.amazon.com/powershell/v4/reference)di *Referensi Alat AWS untuk PowerShell Cmdlet (V4)*. 

**Alat untuk PowerShell V5**  
**Contoh 1: Contoh ini membuat Alias Lambda Baru untuk versi tertentu dan konfigurasi perutean untuk menentukan persentase permintaan pemanggilan yang diterimanya.**  

```
New-LMAlias -FunctionName "MylambdaFunction123" -RoutingConfig_AdditionalVersionWeight @{Name="1";Value="0.6} -Description "Alias for version 4" -FunctionVersion 4 -Name "PowershellAlias"

# Secara otomatis memigrasikan pengguna Amazon Cognito yang dikenal dengan fungsi Lambda menggunakan SDK AWS
<a name="example_cross_CognitoAutoMigrateUser_section"></a>

Contoh kode berikut menunjukkan cara memigrasi pengguna Amazon Cognito yang dikenal secara otomatis dengan fungsi Lambda.
+ Konfigurasikan kumpulan pengguna untuk memanggil fungsi Lambda untuk pemicu. `MigrateUser`
+ Masuk ke Amazon Cognito dengan nama pengguna dan email yang tidak ada di kumpulan pengguna.
+ Fungsi Lambda memindai tabel DynamoDB dan secara otomatis memigrasikan pengguna yang dikenal ke kumpulan pengguna.
+ Lakukan alur lupa kata sandi untuk mengatur ulang kata sandi untuk pengguna yang dimigrasi.
+ Masuk sebagai pengguna baru, lalu bersihkan sumber daya.
