golang操作进程包，获取进程和杀死进程等操作，推荐一个常用包 "github.com/shirou/gopsutil/process" 比如我要打印所有进程名字和ID如下所示： type Pdata struct {
Pid int32
Pname string
}
func main() {
pName := ProcessName()
for _, v := range pName {
fmt.Println("进程名:", v)
}
}
/*
获取所有进程名，以数组返回
*/
func ProcessName() (pname []Pdata) {
pids, _ := process.Pids()
for _, pid := range pids {
rtn := new(Pdata)
rtn.Pid = pid
pn, _ := process.NewProcess(pid)
pName, _ := pn.Name()
rtn.Pname = pName
pname = append(pname, *rtn)
}
return pname
}以下是此包常用方法Index ¶
