我使用 golang 编写了一个简单的 Windows 服务。
package main
import "golang.org/x/sys/windows/svc"
import "io/ioutil"
import "log"
import "encoding/json"
import "time"
import "strconv"
import "os"
import "./cmd"
import "golang.org/x/sys/windows/svc/eventlog"
import "fmt"
type myservice struct{}
func (m *myservice) Execute(args []string, r <-chan svc.ChangeRequest, changes chan<- svc.Status) (ssec bool, errno uint32) {
log.Println("Starting service")
const cmdsAccepted = svc.AcceptStop | svc.AcceptShutdown | svc.AcceptPauseAndContinue
changes <- svc.Status{State: svc.StartPending}
changes <- svc.Status{State: svc.Running, Accepts: cmdsAccepted}
StartService(r, changes)
return
}
//RunService Runs the current application as a service.It will send the necessary flags to windows.
func RunService(maintServiceName string) {
//var elog eventlog
elog, evtErr := eventlog.Open(maintServiceName)
if evtErr != nil {
return
}
defer elog.Close()
log.Println("Running service")
elog.Info(1, fmt.Sprintf("starting %s service", maintServiceName))
run := svc.Run
sererr := run(maintServiceName, &myservice{})
if sererr != nil {
elog.Error(1, fmt.Sprintf("%s service failed: %v", maintServiceName, sererr))
}
}
//StartService Starts the Service
func StartService(r <-chan svc.ChangeRequest, changes chan<- svc.Status) {
const cmdsAccepted = svc.AcceptStop | svc.AcceptShutdown | svc.AcceptPauseAndContinue
jsonFile, err := os.Open("config.json")
if err != nil {
log.Fatalln("No configuration found")
}
该应用程序大部分时间运行一两天都没有问题,但之后停止而没有任何错误。发生这种情况时,日志中的 sleep line 后没有日志。我可以添加任何内容以获取有关服务失败的更多信息。这里可能是什么问题?
