Question

我在使用localhost时如何启用浏览器通知，在控制台Notification.requestPermission();中写入时没有任何内容，但在任何常规站点上写入控制台if($count['total_runs'] == null || $count['total_runs'] == 0) { continue; }时，请求权限。

如何启用它来测试我的代码？非常感谢你提前...

Answer 2

在ubuntu中，你应该这样运行chrome实例

whereis google-chrome 找到您的可执行文件

/usr/bin/google-chrome --unsafely-treat-insecure-origin-as-secure=http://your-domain.dev:80

记得在执行此操作之前关闭所有其他 chrome 实例 (pkill -9 chrome)

Answer 3

请检查浏览器版本是否支持通知，并尝试使用http：// {localhost ip} instad of localhost / xyz。

Answer 4

您应该尝试PushJS，https://pushjs.org

它是一个轻松创建桌面通知的插件。如果它是新的，请参见此https://tutorialzine.com/2017/01/the-easiest-way-to-show-browser-notifications。

希望它有所帮助！

<强>更新

PushJS使用您正在谈论的相同Notification API。

它使创建和管理浏览器通知变得更加容易。阅读我上面提到的文章。

＆＃34; Push.js库不是使用Web Notifications所必需的，但它提供了一个干净的API，与本机Notification API相比，它更容易使用。 Push.js将处理权限，服务工作者和跨浏览器的不一致，因此我们不必这样做。＆＃34; - 来自Tutorialzine的文章
