Python實現FTP文件的上傳和下載

    ftp = FTP()
    # ftp.set_debuglevel(2)
    ftp.connect(host, 21)
    ftp.login(username, password)
    return ftp

if __name__ == "__main__":
    ftp = ftp_connect("172.21.11.79", "ftpuser", "123456")
    download_file(ftp, r"IMG_0682.jpg", r"C:\Users\lenovo\Desktop\最新接口\img.jpg")
    #調用本地播放器播放下載的視頻
    os.system('start "C:\Program Files\Windows Media Player\wmplayer.exe" "C:/Users/Administrator/Desktop/test.mp4"')
    upload_file(ftp, r"IMG_0682.jpg", "E:\咱們的照片\新建文件夾\IMG_0682.jpg")

    ftp.quit()
