ftp's Introduction
执行说明: 两个文件夹分别执行make后生成两个可执行文件:client server 先在一个终端执行server文件夹中的server 先转换为root用户,再执行./server ip port 之后在另一个终端执行client文件夹中的client ./client ip port 说明:client和server的ip都是服务器端的ip,并且两端的端口号一致才可以。 使用说明: 先在client端登录 用户名:user1 密码:123 之后client端可以执行: 指令 说明 ls 查看server端当前目录的文件 pwd 查看client所在的server端的当前路径 removefilename 删除server端filename文件 cdpath 进入到server端的path路径里面(path必须是绝对路径) getsfilename 从server端下载filename文件到client端 putsfilename 从client端上传filename到server端 其他指令 一律当做无效指令 问题说明: 一、指令与作用对象之间不能有空格:一旦有空格就会被当做两条指令来处理,如:gets filename会被当做 gets和filename两个指令 二、断点续传功能的不完全实现:什么是断点续传? 在客户端登录后执行:getsfilename 然后随便输入几个字符暂停下载:asdfadsf 之后继续下载:getsfilename 这样问题就出现了:第二次下载时,文件会下载到一半就出现地址错误而无法继续下载。 添加文本查询的模块(C++): 目前该模块并没有合并到住模块中,仅实现了文本查询的功能并通过了单元测试。该模块的原型是C++ Primer的第15章的实例。这个实例对我的 启发非常大。让我感受到继承后使用多态机制的巨大好处。但是我需要更多的时间去理解如何利用继承去思考问题。 下个目标:使用C++重写主模块,实现服务-客户的通讯。
