win7系统两台电脑之间利用socket实现win7局网内互相通信文件传输

      参考

    本博客主要实现了简单win7系统下两台电脑之间(客户机与服务器)的文件传输主要是基于网络编程中来实现的当然这个只是简单的实现你可以根据你的需求在你的项目里面进行更改。这里主要实现的通过客户机()通过监听服务器的需求进而向服务器传输指定文件。

操作步骤

    (1)首先打开你的cmd控制台查看你的端口号输入命令-ano如下图所示TCP后面红色矩形框就是你部分的端口号。在和这两个文件中将“# 1029“改为你的可用端口号比如“#definePORT 8128“其中8128就是你某个可用端口号。

 (2)如果你在同一台电脑上面进行模拟是不用更改IP的当然如果是两台电脑这里就需要更改你的client.cpp和server.cpp这两个文件中#defineSERVER_IP“127.0.0.1”更改为你的Server服务器IP地址查看你IP地址的方法为打开你的打开你的cmd控制台输入命令ipconfig

     (3)然后新建两个工程即可分别添加下面两个源文件先运行客户端代码然后运行服务器代码输入想要接收客户端的文件名就可以在你的服务器工程下接收到相应的文件。
