据我了解,当您运行Windows服务时,它会调用“ onStart()”,并说该服务正在任务管理器中“启动”,直到“ onStart()”方法完全运行为止。然后显示“正在运行”。我想创建一个线程来启动Bluetooth Advertising Script(用Python3编写),该脚本将在未连接到设备时连续地进行通告。当我尝试创建线程并运行脚本时,该服务通常仅在任务管理器中显示“正在启动”,而从未真正说“正在运行”,因为我在“ onStart()”中调用以启动脚本的线程永远不会完成我猜想,有没有办法让服务启动,仅在完成执行“ onStart()”之后才启动线程?

虽然可能还有其他问题,但第一个问题是您的服务(可能)运行的本地服务帐户没有位置libdlib-dev
如果将“运行方式”帐户更改为具有权限的帐户,您将走得更远。我不是Python怪胎,但是如果您的py应用程序需要任何类型的用户I / O,它将失败,因为没有分配控制台会话。
此外,如果您具有漫游配置文件,则该服务会在用户文件夹可用之前从其启动,因此它将挂起或失败。
