关于用JAVA开发短信方面的知识

 

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 = "";
connection = null;
input = null;
out = null;
binput = null;
}
//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)
port = default_port;
try
{
connection = new Socket(ip, port);
input = connection.getInputStream();
binput = new BufferedInputStream(input);
out = connection.getOutputStream();
result = true;
connectStatus = true;
default_ip = ip;
default_port = port;
}
catch(Exception e)
{
result = false;
}
return result;
}

//登录函数



public int login(String userName, String password)
{
int loginRes = -1;
if(!connectStatus)
return 1;
if(userName == null || userName.trim().equals(""))
return 24;
byte loginData[] = new byte[43];
setIntData(43, loginData, 0);
setIntData(1, loginData, 4);
setIntData(1, loginData, 8);
userName.getBytes(0, userName.length(), loginData, 12);
password.getBytes(0, password.length(), loginData, 22);
loginData[38] = 1;
setTime((new Date()).getTime() / (long)1000, loginData, 39);
try
{
out.write(loginData);
out.flush();
byte rec[] = new byte[30];
char ret = '';
int i = 0;

break;

{

return k;

return j;

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。
