unity3d登陆代码主要用到了unity内置的WWW类和WWWForm类，运用WWWForm.AddField(String fieldName, String value)方法通过post的表单提交方式把表单参数传递给服务器端的逻辑业务层。（我用的是JSP，在逻辑层上request.getParameter(fiedlName);就能得到AddField中传递的参数，接下来就是服务器的逻辑处理了。PHP貌似是$_POST[fieldName]吧，好久没写过php了，ASP.NET不着咋写...)
客户端的demo效果图:
imei是手机的唯一识别id，用imei表示可能不恰当...

服务器端注册逻辑：
1 <%@ page language="java" import="ddt.*" %> 2 <jsp:useBean id="user" scope="session" class="ddt.UserBean" /> 3 <%@page contentType="text/html" pageEncoding="UTF-8"%> 4 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" 5 "http://www.w3.org/TR/html4/loose.dtd"> 6 <html> 7 <head> 8 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 9 <title>JSP Page</title> 10 </head> 11 <body> 12 <% 13 String id = request.getParameter("id"); 14 String username = request.getParameter("name"); 15 String password = request.getParameter("password"); 16 String retry_password = request.getParameter("retry_password"); 17 String email = request.getParameter("email"); 18 user.processRegisterUserRequest(id, username, password, retry_password, email, request, response); 19 %> 20 </body> 21 </html>
user.processRegisterUserRequest方法是注册就是处理了。登录等其他功能也是采用同样的业务处理流程，不再详述了。
