"Cannot read properties of undefined (reading 'getUserMedia')"是一个错误提示,意味着在代码中尝试读取未定义属性'getUserMedia'时发生了错误。这个属性通常与使用摄像头和音频设备相关。根据所提供的引文,这个错误与浏览器的安全限制有关。
在引文中,错误发生在尝试调用navigator.mediaDevices.getUserMedia()方法时。类似地,在引文中,错误发生在调用getUserMedia()方法时。这些错误可能是由于使用了http协议而不是https协议,因为谷歌浏览器对http协议下的getUserMedia()方法有安全限制。
解决方案是升级到https协议以解决该错误。通过使用https协议,浏览器会对getUserMedia()方法的访问进行授权,从而允许调用摄像头和音频设备。
在引文中提到,谷歌浏览器限制了在http协议下调用摄像头的权限,这是出于安全考虑,以防止网站滥用用户的摄像头和侵犯隐私。
综上所述,"Cannot read properties of undefined (reading 'getUserMedia')"这个错误表示在尝试读取未定义属性'getUserMedia'时发生了错误,可能是由于浏览器的安全限制。解决方案是使用https协议来调用摄像头和音频设备。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
