Unity与注册登录服务器交互原理及code

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...

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。
