应用程序模块中未触发事件

Question

我似乎无法启动我的活动。这是我第一次和他们一起玩。如果你看的话，我会在

init

方法中创建一个事件，然后尝试在

onBootstrap

方法中触发它。该事件应该产生带有字符串的骰子，但事实并非如此。任何帮助将不胜感激。

namespace Application;

            $target = get_class($e->getTarget());

您从

EventManager

获得的

ModuleManager

与您触发事件

EventManager

的

Application

的

EventManager

不同。由于在模块初始化期间应用程序尚不可用，因此您必须通过

do

将侦听器绑定到事件。

所以附加到应用程序的事件

SharedManager

会像这样

do

请注意，共享管理器需要预期触发事件的 EventManager 的标识符，在本例中是（通常是）

$sharedManager = $manager->getEventManager()->getSharedManager();
$sharedManager->attach(Application::class, 'do', function($e) {
    // event code
});

的类名。
