swoft运行流程
启动命令 php bin/swoft http:start
或者 swoftctl run -c http:start
1 入口文件 bin/swoft.php
#!/usr/bin/env php <?php // Bootstrap require_once __DIR__ . '/bootstrap.php'; Swoole\Coroutine::set([ 'max_coroutine' => 300000, ]); // Run application (new \App\Application())->run();
new Application 进入文件 app/Application
<?php declare(strict_types=1); /** * This file is part of Swoft. * * @link https://swoft.org * @document https://swoft.org/docs * @contact group@swoft.org * @license https://github.com/swoft-cloud/swoft/blob/master/LICENSE */ namespace App; use Swoft\SwoftApplication; use function date_default_timezone_set; /** * Class Application * * @since 2.0 */ class Application extends SwoftApplication { protected function beforeInit(): void { parent::beforeInit(); // you can init php setting. date_default_timezone_set('Asia/Shanghai'); // 设置时区 } /** * @return array */ public function getCLoggerConfig(): array { $config = parent::getCLoggerConfig(); // False: Dont print log to terminal $config['enable'] = true; return $config; } }
发现他继承 SwoftApplication 要执行父类的construct方法
进入 SwoftApplication 发现初始化方法
/**
* Class constructor.
*
* @param array $config
*/
public function __construct(array $config = [])
{
// Check runtime env 检查运行环境是否符合 php版本 swoole版本
SwoftHelper::checkRuntime();
// Storage as global static property.
Swoft::$app = $this; // 当前对象赋值给
// Before init
$this->beforeInit();
// Init console logger
$this->initCLogger(); //初始化 打印到console界面的日志系统
// Can setting properties by array
if ($config) {
ObjectHelper::init($this, $config); // 初始化配置
}
// Init application
$this->init(); // 真真的初始化
// After init
$this->afterInit(); // 初始化完执行
}
进入 $this->init()
protected function init(): void
{
// Init system path aliases
$this->findBasePath(); // 找到当前基本路径
$this->setSystemAlias(); // 设置系统别名
$processors = $this->processors(); //重要 实例化几个进程 返回
$this->processor = new ApplicationProcessor($this); // 实例化$this->processor 也就是当前application运用的属性 后面会执行他的handel方法
$this->processor->addFirstProcessor(...$processors); // 把第一个processor添加到 $this->processors
}
/**
* @return ProcessorInterface[]
*/
protected function processors(): array
{
return [
new EnvProcessor($this), // 环境
new ConfigProcessor($this), // 配置
new AnnotationProcessor($this), // 注解
new BeanProcessor($this), // bean
new EventProcessor($this), // 事件
new ConsoleProcessor($this),
];
}
$this->processor = new ApplicationProcessor($this)；
调用每个process的handel方法
/**
* Handle application processors
*/
public function handle(): bool
{
$disabled = $this->application->getDisabledProcessors();
foreach ($this->processors as $processor) {
$class = get_class($processor);
// If is disabled, skip handle.
if (isset($disabled[$class])) {
continue;
}
$processor->handle();
}
return true;
}
$this->processor->addFirstProcessor(...$processors); // 把这些对象都丢到$this->processors里面
public function addFirstProcessor(Processor ...$processor): bool
{
array_unshift($this->processors, ... $processor);
return true;
}
实例化 基本执行完成，开始run
// Run application
(new \App\Application())->run();
/**
* Run application
*/
public function run(): void
{
try {
if (!$this->beforeRun()) {
return;
}
$this->processor->handle();
} catch (Throwable $e) {
Console::colored(sprintf('%s(code:%d) %s', get_class($e), $e->getCode(), $e->getMessage()), 'red');
Console::colored('Code Trace:', 'comment');
echo $e->getTraceAsString(), "\n";
}
}
调用当前对象的 handle方法
public function handle(): bool
{
$disabled = $this->application->getDisabledProcessors();
foreach ($this->processors as $processor) {
$class = get_class($processor);
// If is disabled, skip handle.
if (isset($disabled[$class])) {
continue;
}
$processor->handle();
}
return true;
}
这个时候 将之前保存到$this->pkrocesssors里面的对象的handle方法执行一遍
初始化完成
string(29) "Swoft\Processor\BeanProcessor"
string(31) "Swoft\Processor\ConfigProcessor"
string(35) "Swoft\Processor\AnnotationProcessor"
string(28) "Swoft\Processor\EnvProcessor"
string(32) "Swoft\Processor\ConsoleProcessor"
代码位于framwork/processor
比如 执行beanprocessor 下面的handle方法 做了一大堆事情，好像是初始bean化容器 把注解 定义 解析等都挂到container的属性上去
BeanFactory::addDefinitions($definitions);
BeanFactory::addAnnotations($annotations);
BeanFactory::addParsers($parsers);
BeanFactory::setHandler($handler);
BeanFactory::init();
public static function addAnnotations(array $annotations): void
{
Container::getInstance()->addAnnotations($annotations);
}
public function addAnnotations(array $annotations): void
{
$this->annotations = ArrayHelper::merge($this->annotations, $annotations);
}
