标题：J2EE－－关于用JAVA开发短信方面的知识
＜上一帖 |
下一帖＞
现在流行的网络业务莫过于短信了.网易新浪等都因此而盈利,股价上涨.我凭自己的经验和公司支持,也就
乘着东风来研究一下了!
首先,你要选择一台移动或者联通的短信服务器做你们的发送短信接口.这是最关键的一步,也是最底层的,
当然这是需要much money的,呵呵.没办法!现实了点....
然后你就是在连接接口的服务器做技术了.用JAVA 的 SOCKET 来监听客户端的SOCKET,当然这是需要一定的
难度,和普通是有很多的区别,例如每秒钟可以同时接受3000条SOCKET... ...,要进行客户端的认证.要进行数据
流转输的加密... ...
最后就是来处理客户端的发送SOCKET了,其实他们传输都是字节Byte...
public class Client
{
//构造函数
public Client()

connectStatus = false;
loginStatus = false;
default_ip = "";
default_port = 0;
default_user = "";

out = null;
binput = null;
}
//连接函数

{
boolean result = false;
