int __cdecl _tmain(int argc, TCHAR *argv[])
{ SERVICE_TABLE_ENTRY DispatchTable[] { { SVCNAME, (LPSERVICE_MAIN_FUNCTION) SvcMain }, { NULL, NULL } }; if (!StartServiceCtrlDispatcher( DispatchTable )) { SvcReportEvent(TEXT(StartServiceCtrlDispatcher)); }
}
编写 ServiceMain 函数 注册控制处理函数 RegisterServiceCtrlHandler(SvcCtrlHandler )设置服务状态SERVICE_START_PENDING做一些预备工作比如初始化日志/注册事件等设置服务状态SERVICE_START_RUNNING开始loop处理我们自己的代码loop循环中可以接受3中注册的事件当通知停止时退出循环 编写控件处理程序函数 接受事件管理器发送的消息并处理比如收到SERVICE_CONTROL_STOP时使用3中注册的事件句柄发送停止事件
二Rust中编写windows服务 借用第三方库 windows-service 0.7.0 https://crates.io/crates/windows-service 参考windows-service中ping-service示例提取了一个模板只有替换编写两处/* */代码 use std::{ffi::OsString,sync::mpsc,time::Duration,
};
use windows_service::{define_windows_service,service::{ServiceControl, ServiceControlAccept, ServiceExitCode, ServiceState, ServiceStatus,ServiceType,},service_control_handler::{self, ServiceControlHandlerResult},service_dispatcher,
};static SERVICE_NAME: str Rust Demo Service;fn main() - Result(), windows_service::Error {service_dispatcher::start(SERVICE_NAME, ffi_service_main)?;Ok(())
}define_windows_service!(ffi_service_main, my_service_main);fn my_service_main(arguments: VecOsString) {let _ arguments;/*这里服务还没开始 可以填写初始化日志文件等操作*/let (shutdown_tx, shutdown_rx) mpsc::channel();// 对应SvcCtrlHandlerlet _event_handler move |control_event| - ServiceControlHandlerResult {match control_event {ServiceControl::Interrogate ServiceControlHandlerResult::NoError,// 处理停止事件ServiceControl::Stop {shutdown_tx.send(()).unwrap();ServiceControlHandlerResult::NoError}// 其他用户事件都当作停止事件处理ServiceControl::UserEvent(code) {if code.to_raw() 130 {shutdown_tx.send(()).unwrap();}ServiceControlHandlerResult::NoError}_ ServiceControlHandlerResult::NotImplemented,}};let status_handle service_control_handler::register(SERVICE_NAME, _event_handler);let status_handle status_handle.unwrap();let _ status_handle.set_service_status(ServiceStatus {service_type: ServiceType::OWN_PROCESS,current_state: ServiceState::Running,controls_accepted: ServiceControlAccept::STOP,exit_code: ServiceExitCode::Win32(0),checkpoint: 0,wait_hint: Duration::default(),process_id: None,});loop {/*这里写自己的代码逻辑下面时处理一次循环后睡眠5秒若是接受到停止等消息退出循环*/match shutdown_rx.recv_timeout(Duration::from_secs(5)) {Ok(_) | Err(mpsc::RecvTimeoutError::Disconnected) break,Err(mpsc::RecvTimeoutError::Timeout) (),}}let _ status_handle.set_service_status(ServiceStatus {service_type: ServiceType::OWN_PROCESS,current_state: ServiceState::Stopped,controls_accepted: ServiceControlAccept::empty(),exit_code: ServiceExitCode::Win32(0),checkpoint: 0,wait_hint: Duration::default(),process_id: None,});
}
三具体实例 笔记本策略经常恢复到合上盖子睡眠功能写个小服务定时设置合上盖子不做任何操作 逻辑比较简单定时调用WinAPI函数CallNtPowerInformation获取配置信息不符合当前设置执行修改 完整如下 use std::{ffi::{c_void, OsString},sync::mpsc,time::Duration,
};
use windows::Win32::{Foundation::STATUS_SUCCESS, System::Power::{CallNtPowerInformation, POWER_INFORMATION_LEVEL, SYSTEM_POWER_POLICY}};
use windows_service::{define_windows_service,service::{ServiceControl, ServiceControlAccept, ServiceExitCode, ServiceState, ServiceStatus,ServiceType,},service_control_handler::{self, ServiceControlHandlerResult},service_dispatcher,
};static SERVICE_NAME: str Power Lid Service;fn main() - Result(), windows_service::Error {service_dispatcher::start(SERVICE_NAME, ffi_service_main)?;Ok(())
}define_windows_service!(ffi_service_main, my_service_main);fn my_service_main(arguments: VecOsString) {let _ arguments;let (shutdown_tx, shutdown_rx) mpsc::channel();let _event_handler move |control_event| - ServiceControlHandlerResult {match control_event {ServiceControl::Interrogate ServiceControlHandlerResult::NoError,ServiceControl::Stop {shutdown_tx.send(()).unwrap();ServiceControlHandlerResult::NoError}ServiceControl::UserEvent(code) {if code.to_raw() 130 {shutdown_tx.send(()).unwrap();}ServiceControlHandlerResult::NoError}_ ServiceControlHandlerResult::NotImplemented,}};let status_handle service_control_handler::register(SERVICE_NAME, _event_handler);let status_handle status_handle.unwrap();let _ status_handle.set_service_status(ServiceStatus {service_type: ServiceType::OWN_PROCESS,current_state: ServiceState::Running,controls_accepted: ServiceControlAccept::STOP,exit_code: ServiceExitCode::Win32(0),checkpoint: 0,wait_hint: Duration::default(),process_id: None,});loop {unsafe {let mut a: SYSTEM_POWER_POLICY std::mem::zeroed();let status CallNtPowerInformation(POWER_INFORMATION_LEVEL { 0: 8 },None,0,Some(mut a as *mut SYSTEM_POWER_POLICY as *mut c_void),size_of::SYSTEM_POWER_POLICY() as u32,);if status ! STATUS_SUCCESS {println!(获取电源状态失败: {:x} !, status.0);return;}if a.LidClose.Action.0 0 {println!(状态已为0, 忽略);return;} else {println!(状态为{:x}, a.LidClose.Action.0);a.LidClose.Action.0 0;let status CallNtPowerInformation(POWER_INFORMATION_LEVEL { 0: 0 },Some(mut a as *mut SYSTEM_POWER_POLICY as *mut c_void),size_of::SYSTEM_POWER_POLICY() as u32,None,0,);if status ! STATUS_SUCCESS {println!(设置ac电源状态失败: {:x} !, status.0);return;} else {println!(设置AC电源状态成功);}let status CallNtPowerInformation(POWER_INFORMATION_LEVEL { 0: 1 },Some(mut a as *mut SYSTEM_POWER_POLICY as *mut c_void),size_of::SYSTEM_POWER_POLICY() as u32,None,0,);if status ! STATUS_SUCCESS {println!(设置dc电源状态失败: {:x} !, status.0);return;} else {println!(设置DC电源状态成功);}}}match shutdown_rx.recv_timeout(Duration::from_secs(5)) {Ok(_) | Err(mpsc::RecvTimeoutError::Disconnected) break,Err(mpsc::RecvTimeoutError::Timeout) (),}}let _ status_handle.set_service_status(ServiceStatus {service_type: ServiceType::OWN_PROCESS,current_state: ServiceState::Stopped,controls_accepted: ServiceControlAccept::empty(),exit_code: ServiceExitCode::Win32(0),checkpoint: 0,wait_hint: Duration::default(),process_id: None,});
}
