Python socket.listen方法代码示例

        要启动该服务, 调用 `start`. 如果你想要在一个单进程上运行该服务,
        你可以调用 `listen` 作为顺序调用 `bind` 和 `start` 的一个快捷方式.

        address 参数可以是 IP 地址或者主机名.  如果它是主机名,
        该服务将监听在和该名称有关的所有 IP 地址上.  地址也可以是空字符串或者
        None, 服务将监听所有可用的接口. family 可以被设置为 `socket.AF_INET` 或
        `socket.AF_INET6` 用来限定是 IPv4 或 IPv6 地址, 否则如果可用的话, 两者
        都将被使用.

        ``backlog`` 参数和 `socket.listen <socket.socket.listen>` 是相同含义.

        这个方法可能在 `start` 之前被调用多次来监听在多个端口或接口上.
