c++ ftplib 连接ftp与创建文件夹

#include "ftplib.h"
void _CreateDir()
 {
     ftplib *ftp = new ftplib();
     int ret = ftp->Connect("127.0.0.1:21");
     if (ret != 1)
     {
         //连接失败
     }
     ret = ftp->Login("test", "123456");
     if (ret != 1)
     {
         //登录失败
     }    //1、创建文件夹
     ret = ftp->Mkdir("newDir");
     if (ret != 1)
     {
         //创建文件夹失败
     }    //ret = ftp->Get("text.txt", "text.txt", ftplib::image);
     ret = ftp->Quit();
     if (ret != 1)
     {
         //退出失败
     }    delete ftp;
     ftp = nullptr;
 }
