我在Angular 6中有一个Progressive Web App,它包含一个音频HTML5标签来播放一些声音。我将其部署到Firebase。
我遇到的问题是Safari浏览器(移动和桌面,最新版本)。服务工作者以某种方式使其成为“直播” 尝试播放声音时(甚至在尝试单击播放按钮之前),渲染的音频标签上会显示消息。
我不会在Chrome中获得此“错误”,仅限于Safari。
我发布了一个示例应用,以便您可以看到问题(请记住 从Safari浏览器访问该应用程序。)
在此存储库中,您可以找到示例应用程序的代码。
“直播”消息是这样的:Live Broadcast message in Safari
我需要用户可以播放音频,而无需在HTML5音频播放器上获得“直播”文字。我认为这与服务工作者配置有关,但我不确定。它也可能是一个角度问题。
任何帮助都会非常感激。
