描述

一个简单的PHP包装库，围绕AWS lambda的运行时API。用于在自定义PHP 8运行时内部使用。

使用方法

lambda 运行时

使用Composer将库安装到您的lambda运行时层或其他用于composer文件的专用层。

composer require intermaterium/kickstart

然后，在您的lambda运行时层中创建一个/opt/bootstrap文件，调用该库。

use Intermaterium\Kickstart\Locator\FileHandlerLocator;
use Intermaterium\Kickstart\Response\ErrorResponseBuilder;
use Intermaterium\Kickstart\RuntimeFactory;

require_once('/opt/vendor/autoload.php');

// Create our runtime from the provided environment
$errorResponseBuilder = new ErrorResponseBuilder();
$runtimeFactory = new RuntimeFactory($errorResponseBuilder);
$runtime = $runtimeFactory->create(getenv('AWS_LAMBDA_RUNTIME_API'));

try {
    // Retrieve the function being invoked by lambda
    $fileHandlerLocator = new FileHandlerLocator(getenv('LAMBDA_TASK_ROOT'));
    $lambdaHandler = $fileHandlerLocator->get(getenv('_HANDLER'));
} catch (\Exception $e) {
    // If we failed to get the handler send an initialisation error and kill the lambda
    $runtime->initialisationFailure('Failed to get lambda handler', $e);
    exit(1);
}

do {
    // Infinitely loop handling events from lambda until lambda kills the runtime
    $runtime->invoke($lambdaHandler);
} while(true);

lambda 函数

Kickstart支持以下形式的aws lambdas：

use Intermaterium\Kickstart\Context\Context;

return function($event, Context $context): mixed {
    return 'Hello ' . ($event['queryStringParameters']['name'] ?? 'world');
};

或可调用的类

use Intermaterium\Kickstart\Context\Context;

class Handler
{
    public function __invoke($event, Context $context): mixed
    {
        return 'Hello ' . ($event['queryStringParameters']['name'] ?? 'world');
    }
}

return new Handler();
