Go 命令列解析示例

func test_flag() {
    ListPort := flag.String("list", "1025", "list port")
    Server := flag.String("server", "192.168.1.134:9000", "server address")
    MonitorServer := flag.String("monitor", "192.168.1.134:9002", "Monitor server address")
    PQPS := flag.Uint("qps", 100, "QPS")

    PMinUserId := flag.Uint
 
("min", 0, "MinUserId")
    PMaxUserId := flag.Uint("max", 99, "MaxUserId")
    PTotalUser := flag.Uint("total", 100, "TotalUser")
    flag.Parse()    //注意, 如果想獲取命令列的指定值, 必須要寫入該行
    fmt.Println(*ListPort, *Server, *MonitorServer, *PQPS)
    fmt.Println(*PMinUserId, *PMaxUserId, *PTotalUser)
}

func main(){
    test_flag()
}
編譯生成 ./server.exe
 
 程式
//輸出:
./server.exe -list 5000 -server 9000 -monitor 9000
5000 9000 9000 100
0 99 100

./server.exe
1025 192.168.1.134:9000 192.168.1.134:9002 100
0 99 100
