事件

绑定事件

  1. 通过模块根目录 events.json 文件绑定。如
    1. [
    2.  {
    3.      "group_title": "分组名称",
    4.      "list": [
    5.          {
    6.              "event": "TestEvent",
    7.              "description": "事件描述",
    8.              "payload": "载荷描述",
    9.              "listeners": [
    10.                  {
    11.                      "name": "app\\test\\events\\Event@onTest",
    12.                      "description": "带方法，执行Event类onTest方法"，
    13.                      "sort": 10,
    14.                      "status": 1
    15.                  },
    16.                  {
    17.                      "name": "app\\test\\events\\Event",
    18.                      "description": "不带方法,执行Event类handle方法",
    19.                      "sort": 10,
    20.                      "status": 1
    21.                  },
    22.               ]
    23.          }
    24.       ]
    25.   }
    26. ]
  2. 通过根目录 event.php 订阅或监听
    1. return [
    2.  'listen' => [
    3.      'Test' => [
    4.          '\\app\\test\\events\\Event@test1',
    5.          '\\app\\test\\events\\Event@test2'
    6.      ]
    7.  ],
    8.  'subscribe' => [
    9.      '\\app\\test\\subscribe\\Event'
    10.  ]
    11. ];
    12. // \app\test\subscribe
    13. class Event 
    14. {
    15.  public function onTestEvent()
    16.  {
    17.      echo 'event trigger';
    18.  }
    19. }
  3. 动态绑定，如
    1. app(\yi\Event::class)->bind('BeforeIndexController', function($payload) {
    2.  // do something
    3. });
    4. app(\yi\Event::class)->bind('BeforeIndexController', '\\app\\test\\events\\Event@test');

触发事件

  1. event('事件名称', 参数)

  2. ev('事件名称', 参数1, 参数2 ...)
    该方式带返回值，如： 

    1. public function onTest($payload)
    2. {
    3.  list($p1, $p2) = $payload->params; // 获取参数
    4.  $payload->result = "param1: $p1, param2: $p2";
    5. }
    6. // 触发事件
    7.  $data = ev('test', 'p1', 'p2');
    8.  echo $data; // param1: p1, param2: p2
