问题描述
屏幕锁定后，是否可以在Mobile-Safari中保持html 5网页WebSocket连接打开？
Is it possible to keep a html 5 web pages WebSocket connection open in Mobile-Safari once the screen is locked?
我想在整个过程中向用户发送持续更新这一天似乎很愚蠢，他们的屏幕应该总是被解锁以接收这些通知。
I want to send my users continuous updates throughout the day and it seems silly that their screens should always have to be unlocked to receive those notifications.
还有其他选择吗？
推荐答案
我发现了一种在移动Safari中保持WebSocket活跃的hacky方式。
I have found a hacky way to keep WebSocket alive in Mobile Safari.
基本上它是相同的解决方案至于。
Basically it's the same solution as for this question.
创建一个无限循环音频文件以保持Javascript运行：
Create an infinity looping audio file to keep Javascript running:
<audio loop src="http://www.sousound.com/music/healing/healing_01.mp3"></audio>
注意：启动音频文件需要一些用户交互。
Note: some user interaction is required to initiate the audio file.
如果WebSocket以与音频或视频文件相同的方式使浏览器保持活动状态，那将是很好的。
It would be nice if a WebSocket kept the browser alive in the same manner as an audio or video file.
PS这也适用于Android 。
PS this also works on Android.
