如何使用Python从结果文件中获取设备的特定细节

Question

我的办公室里有100多台苹果设备。我想知道我想要的设备的细节

我使用PyAtv一个python模块来扫描网络上的设备。

所以我创建了一个脚本，它在调用时给我这样的结果。

rexter@rexter-pc:~$ python3 scan.py

但我想知道特定设备的结果

EXAMPLE >>> python3 scan.py 2424

我试了很多次，但我面临的挑战是多个Services和Identifiers。

任何帮助都是非常感谢的！谢谢!

Answer 1

我假设您使用的是scan函数。

scan函数返回一个List[interface.BaseConfig]。

BaseConfig包含属性name。

所以，你可以试试：

name = '2424'

devices = scan(...)

for device in device:
    if device.name == name:
        my_device = device

Answer 2

您可以传递一个或多个标识符(最好是所有标识符)来扫描：

# Single identifier
confs = await pyatv.scan(loop, identifier="id")

# Multiple identifiers
confs = await pyatv.scan(loop, identifier={"id1", "id2", "id3"})

它与运行atvremote scan时看到的标识符相同。

或者，您可以通过主机传递IP地址(如果设备位于另一个网络上，则不工作)。

confs = await pyatv.scan(loop, hosts=["10.0.0.6"])

这里的文档也对此进行了描述：
