代码如下：
package mainimport ( flag fmt github.com/robfig/cron time)import ( . github.com/codyguo/win)var ( arg string)func init() { flag.stringvar(&arg, uflags, shutdown, shutdown logoff reboot)}func main() { flag.parse() c := cron.new(cron.withseconds()) c.addfunc(0 40 18 * * ?, shutdown) c.start() select {} switch arg { case logoff: logoff() case reboot: reboot() case shutdown: shutdown() default: fmt.println(您输入的参数有误.) }}func test(){ fmt.println(time.now())}func logoff() { exitwindowsex(ewx_logoff, 0)}func reboot() { getprivileges() exitwindowsex(ewx_reboot, 0)}func shutdown() { getprivileges() exitwindowsex(ewx_shutdown, 0)}func getprivileges() { var htoken handle var tkp token_privileges openprocesstoken(getcurrentprocess(), token_adjust_privileges|token_query, &htoken) lookupprivilegevaluea(nil, stringtobyteptr(se_shutdown_name), &tkp.privileges[0].luid) tkp.privilegecount = 1 tkp.privileges[0].attributes = se_privilege_enabled adjusttokenprivileges(htoken, false, &tkp, 0, nil, nil)}
cron表达式
c.addfunc(0 40 18 * * ?, shutdown)
以上就是golang怎么编写一个window定时关机的详细内容。
