Question

我正在使用网络摄像头从程序中捕获图像。当我在计算机上本地运行时，本地笔记本电脑的网络摄像头被打开。但是当我在服务器中部署代码时.... Webcam无法打开。

是否要打开服务器系统的网络摄像头？

我正在使用以下代码打开相机

vel_left = 4
vel_right = -4

run = True
while run:
    # Handle the events.
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    keys = pygame.key.get_pressed()

    # Update the player coordinates.
    if keys[pygame.K_LEFT] and player.left > 0:
        player.x -= vel
    if keys[pygame.K_RIGHT] and player.right < 1200:
        player.x += vel
    if keys[pygame.K_UP] and player.top > 0:
        player.y -= vel
    if keys[pygame.K_DOWN] and player.bottom < 600:
        player.y += vel

    # Game logic for walls and moving objects
    for wall in walls:
        # Check if the player rect collides with a wall rect.
        if player.colliderect(wall):
            print("Game over")

    # Set this variable to True if the direction should be inverted.
    invert_left = False
    for object in movingobjectsleft:
        if player.colliderect(object):
            print("Game over")

        object.x += vel_left  # Move the object.

        # Check if the object has left the area.
        if object.right > 600 or object.left < 320:
            # Invert the direction after the loop.
            invert_left = True

    if invert_left:  # Invert the direction.
        vel_left = -vel_left

    # Now do the same for the right objects.
    invert_right = False
    for object in movingobjectsright:
        if player.colliderect(object):
            print("Game over")

        object.x += vel_right

        if object.right > 600 or object.left < 320:
            invert_right = True

    if invert_right:
        vel_right = -vel_right

我相信您的代码是由Servlet或相关API调用的，后者是服务器端的实现，仅适用于特定的服务器。但是，如果您必须访问客户端Cams并将其通过系统发送，则必须使用JS或Type脚本（例如：Angular，任何基于Js的框架）来实现相同的功能。

下面我分享了如何在Angular中进行讨论： How do I get a webcam working with AngularJS?

希望这会有所帮助！

在服务器中部署代码后，无法访问本地网络摄像头
