示例代码：

let constraints = { video: { facingMode: 'environment' } , audio: false }
const stream = await navigator.mediaDevices.getUserMedia(constraints)
const video = document.querySelector("video");
this.videoStream = stream;
video.srcObject = stream;
await video.play();
this.showBtn = true;
} catch (error) {
console.error('摄像头访问失败:', error);
}
},
stopCamera() {
if (this.videoStream) {
const tracks = this.videoStream.getTracks();
tracks.forEach(track => track.stop());
this.videoStream = null;
}
},

let constraints = { video: { facingMode: 'environment' } , audio: false }
const stream = await navigator.mediaDevices.getUserMedia(constraints)

无法调取正常摄像头，

navigator.mediaDevices.enumerateDevices
获取不到摄像头ID返回的是一个{}

请问各位应该如何解决
