python dbus如何获取对象值

Question

import dbus

session_bus = dbus.SessionBus()
print(session_bus)

serviceName = "com.qcom.QCAT"
service = session_bus.get_object(
    serviceName, # Bus name
    "/Applications/QCAT/QCAT/bin/QCAT", # Object path
)

print(service)
appVersion = service.get_dbus_method('AppVersion')
print(appVersion)

您正在获取有关 appVersion 中方法的信息，而不是调用它并获取其 return 值。尝试添加如下内容：

service_application = dbus.Interface(service, 'com.qcom.Application')
appVersion = service_application.AppVersion()
print(appVersion)
