How to read Parameter Store values from Lambda function

已在 Parameter Store 建立兩個參數

已建立以下 Lambda function Code

import boto3
import json

def lambda_handler(event, context):
    # 初始化 SSM 客戶端
    ssm = boto3.client('ssm')
    
    # 參數名稱
    parameters_to_get = [
        '/Dev/DBServer/MySQL/db-user',
        '/Dev/DBServer/MySQL/db-pwd'
    ]
    
    # 從 Parameter Store 獲取參數值
    response = ssm.get_parameters(
        Names=parameters_to_get,
        WithDecryption=True  # 如果參數是加密的，設置為 True
    )
    
    # 初始化一個變數來存儲參數名稱和值
    parameters_values = {}
    
    # 檢查並讀取每個參數的值
    for param in response['Parameters']:
        parameters_values[param['Name']] = param['Value']
    
    # 列印參數值
    print(f"Parameter Values: {json.dumps(parameters_values)}")
    
    return {
        'statusCode': 200,
        'body': json.dumps(f"Parameter Values: {parameters_values}")
    }

賦予 Lambda 有讀取 SSM 的權限

執行結果

Test Event Name
MyTest

Response
{
  "statusCode": 200,
  "body": "\"Parameter Values: {'/Dev/DBServer/MySQL/db-pwd': 'mypassword', '/Dev/DBServer/MySQL/db-user': 'admin'}\""
}
