我正在开发，需要与google chrome进行一些交互。我在Docker容器中运行我的应用程序。当它在docker外部时，我可以连接到chrome浏览器，但是当它在docker内部时，我会收到类似

答案 0 :(得分：0)
启动应用容器时，可以在MandatoryFields.Task命令中使用--add-host标志：
public void CaptureImage(int request){
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra("android.intent.extras.CAMERA_FACING", android.hardware.Camera.CameraInfo.CAMERA_FACING_FRONT);
cameraIntent.putExtra("android.intent.extras.LENS_FACING_FRONT", 1);
cameraIntent.putExtra("android.intent.extra.USE_FRONT_CAMERA", true);
startActivityForResult(cameraIntent, request);
}
然后，您可以通过docker run主机名访问本地运行的chrome实例。当然，所有这些都要求您使用的端口实际上是开放的（我认为是因为应用程序在容器外部运行）。
