Apple发布了一个getUserMedia将在iOS 11上完全正常运行的声明.安装iOS 11 Beta版本5后,我收到一条消息,我的网站请求访问我的摄像头和麦克风,但似乎该行:

video.src = window.URL.createObjectURL(stream);

要么:

video.srcObject = stream;

不行.没有错误,没有例外,只是手机的相机没有图片.

这是我的完整脚本:

$(function () {
     video = document.getElementById('vid');

     navigator.getUserMedia = navigator.getUserMedia ||
                              navigator.webkitGetUserMedia ||
                              navigator.mozGetUserMedia;

     navigator.getUserMedia(
     {
         audio: true,
         video: { facingMode: "user" }
     }, function (stream) {
         video.srcObject = stream;
         //video.src = window.URL.createObjectURL(stream);
     },
     function (err) {           
         alert(err.name);
     });
});

HTML:

<video id="vid" muted autoplay></video>

有没有人让它工作？任何想法,将不胜感激.

我试图在getUserMedia的帮助下访问iOS Safari上的麦克风.您可以在下面找到我的代码片段.

if (navigator.mediaDevices === undefined) {
  navigator.mediaDevices = {};
}

if (navigator.mediaDevices.getUserMedia === undefined) {
  navigator.mediaDevices.getUserMedia = function(constraints) {
    // First get ahold of the legacy getUserMedia, if present
    let getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;

    // Some browsers just don't implement it - return a rejected promise with an error
    // to keep a consistent interface
    if (!getUserMedia) {
      return Promise.reject(new Error('getUserMedia is not implemented in this browser'));
    }

    // Otherwise, wrap the call to the old …
