推荐答案

也许 Navigator.getUserMedia（） （使用 WebRTC 引擎盖下）是你正在寻找的，虽然我没有看到任何会直接告诉你什么设备可用（设备列表没有暴露给你的代码 - 它在询问时呈现给用户）获得访问可用硬件的许可。）

Perhaps Navigator.getUserMedia() (uses WebRTC under the hood) is what you're looking for, though I don't see anything that will directly tell you what devices are available (the list of devices isn't exposed to your code—it's presented to the user when asking for permission to access available hardware).
