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 = "";

default_password = "";

}

//连接函数

public boolean connect(String ip, int port)

{

boolean result = false;

if(ip == null || ip.indexOf(".") < 1)

ip = default_ip;

if(port < 1)

}

//登录函数

break;

}

Thread.sleep(10L);

if(sRet == 'T')

subRes = 0;

else

subRes = 11;

}

catch(Exception e)

{

}

return subRes;

}

当然要根据不同的参数来判断不同的错误和正确的发送.就谈这么多了,如果大家有什么不明的,可以和我联系.
