• 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';
    
    SwooleCoroutine::set([
        'max_coroutine' => 300000,
    ]);
    
    // Run application
    (new AppApplication())->run();

    new Application 进入文件 app/Application

    <?php declare(strict_types=1);
    /**

     * @license  https://github.com/swoft-cloud/swoft/blob/master/LICENSE
     */
    
    namespace App;
    
    use SwoftSwoftApplication;
    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 AppApplication())->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(), " ";
    }
    }


    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) "SwoftProcessorBeanProcessor"

    string(31) "SwoftProcessorConfigProcessor"

    string(35) "SwoftProcessorAnnotationProcessor"

    string(28) "SwoftProcessorEnvProcessor"

    string(32) "SwoftProcessorConsoleProcessor"

     

    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);
    }
