swoft 使用协程 初试

控制器访问 /hi

/**
	 * @Swoft\Bean\Annotation\Mapping\Inject("UserService")
	 * @var  UserService
	 */
	public $userService;
    /**
     * @RequestMapping("/")
     * @throws Throwable
     */
    public function index(): Response
    {
        /** @var Renderer $renderer */
        $renderer = Swoft::getBean('view');
        $content  = $renderer->render('home/index');

        return context()->getResponse()->withContentType(ContentType::HTML)->withContent($content);
    }

    /**
     * @RequestMapping("/hi")
     *
     * @return Response
     */
    public function hi()
    {
		return $this->userService->test();
    }

　　

调用service  里面使用协程 最终访问前端页面 立马返回了 数据

UserService.php

<?php

namespace App\Service;
use function foo\func;
use Swoft\Bean\Annotation\Mapping\Bean;
use Swoft\Co;
use Swoft\Log\Helper\CLog;

/**
 * Class UserService
 * @Bean("UserService")
 * @package App\Service
 */
class UserService
{
	public function __construct()
	{

	}

	public function test()
	{
		Co::create(function(){
			Co::sleep(10);
			for($i=0;$i<10;$i++){
				CLog::info("hello");
			}

		});

		Co::create(function(){
			Co::sleep(20);
			var_dump("world");
		});

		$id = Co::id();
		var_dump($id);
		$id = Co::tid();
		var_dump($id);
		return "nihao";
	}

}

　　

过了十秒 和二十秒后分别打印出了数据

erver start success (Master PID: 18085, Manager PID: 18090)
int(2)
int(2)
2020/07/20-20:22:49 [INFO] App\Service\UserService:App\Service\{closure}(28) hello

2020/07/20-20:22:49 [INFO] App\Service\UserService:App\Service\{closure}(28) hello
string(5) "world"

　　

改为帮助函数

sgo(function(){
   Co::sleep(10);
   for($i=0;$i<10;$i++){
      CLog::info("hello");
   }

});

srun

启动协程并等待执行结束。

public function test()
{
   srun(function(){
      sgo(function(){

         for($i=0;$i<10;$i++){
            Co::sleep(1);
            CLog::info("hello");
         }

      });

      sgo(function(){
         for($i=0;$i<10;$i++){
            Co::sleep(1);
            CLog::warning("hello");
         }
      });

      return true;

     });

   $id = Co::id();
   var_dump($id);
   $id = Co::tid();
   var_dump($id);
   return "nihao";
}
