系统单点登录coremail邮箱

基本思路：在模块中配置好海信邮箱的域名、服务器IP和端口号。根据当前用户AD从系统配置库中获取到用户的邮箱地址，用户在KM系统中第一次（第一次操作之后，系统会保存一份文档，下次点击链接时直接登录）登录邮箱时，运行一个代理跳转到登录页面，在登录页面中选择好域名和登录语言，通过代理把“域名、服务器IP、端口号、用户邮箱、服务提供商（电信或网通）等参数传到servlet文件中，servlet文件根据coremail工程师提供的JAVA接口来写。代码如下：

iimport tebie.applib.api.APIContext;
import tebie.applib.api.IClient;
import java.net.Socket;
import javax.servlet.*;

import java.net.*;
public class LoginCoreMail extends HttpServlet {
       String msg;
       String cookieValue = Long.toHexString(new Random().nextLong());   //随机生成一个数字字符串
       public LoginCoreMail() {
              msg = null;
       }
       public String getLoginURL(String AddrIP,String ParremoteIP,String Parport,String Parlanguage,String Pardomain,String 
ParmailName,String ParwebService){
              APIContext apic = null;
              IClient client = null;
              Socket socket;
              String mailsvrurl = null;
              try{
                     socket = new Socket(ParremoteIP, Integer.parseInt(Parport));
                     client = APIContext.getClient(socket);
               String UserName = ParmailName;
            String language = Parlanguage;
              String style = ParwebService;
              String IpCheck = "";
            apic = client.userLoginEx(UserName, "language=" + language + "&style=" + style + "&remote_ip=" + AddrIP + 
"&ipcheck=" + IpCheck +"&cookiecheck=" + cookieValue);     //通过coremail工程师提供的JAVA接口，获取到APIContext对象。
            int retcode = apic.getRetCode();
            if (retcode == 0) {
                String result = apic.getResult();
                int sidBegin = result.indexOf("sid=");
                    int webnameBegin = result.indexOf("webname=");
                 // assert sidBegin != -1 && webnameBegin != -1;
                  int sidEnd = result.indexOf('&', sidBegin);
                  int webnameEnd = result.indexOf('&', webnameBegin);
                  String sid = URLDecoder.decode((sidEnd != -1) ? result.substring(sidBegin+4 ,sidEnd) : result.substring
(sidBegin+4));        //得到当前用户登录的session id
                  String webname = URLDecoder.decode((webnameEnd != -1) ? result.substring(webnameBegin+8 , 
webnameEnd):result.substring(webnameBegin+8));
