项目使用TCP进行文件传输，接收端做为服务端，发送端为客户端
更多惊喜：https://bbs.pediy.com/user-854079-1.htm
之前发过一个类型的，是双向服务，这次为单项，服务端不能直接向客户端请求
源码在附件中
思路如下
1，服务端开启服务，设置好端口(随机)
2，客户端扫描局域网中所有IP(设备名新协议已经不支持获取)，选中要连接的IP，填入端口号，进行连接
3，客户端选择文件并请求上传文件，等待中
4，服务端确认要收文件
5，客户端开始上传文件
使用DataOutputStream进行数据的传输，其中writeUTF可以作为附加数据，可当作请求参数使用
代码均为测试，比较简陋，优化程度较大，有兴趣可在此基础上自由发挥
