Html5网页录音，js录音mp3
最近有些小伙伴询问为啥在新版chrome里无法打开麦克风的问题：
getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
链接里面提到"localhost is treated as a secure origin over HTTP", 所以就有了你遇到的差别现象.
解决办法是用HTTPS或者在chrome运行参数里加个标记(见上方链接).
