unity3d游戏开发之成功实现对数据库读取登陆

1,创建一个数据库表,我们就以 test数据库为例,数据库里建一个tb_User表, tb_User里有User_Name , User_Pass 字段. 2,创建一个验证用户基本信息的asp.net页面，页面名字是：Default.aspx 后台代码如下: using System; using System.Configuration; using System.Data; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Data.SqlClient; public partial class _Default : System.Web.UI.Page { SqlConnection conn = new SqlConnection("Data Source=.sqlexpress2008;Initial Catalog=test;Integrated Security=True"); protected void Page_Load(object sender, EventArgs e) { string name = Request.Form["name2"; string pwd=Request.Form["pwd"; conn.Open(); string sql = "select User_Name from tb_User where User_Name='" + name + "' and User_Pass='"+pwd+"'"; SqlCommand cmd = new SqlCommand(sql, conn); if (cmd.ExecuteScalar() != null) Response.Write("success"); else Response.Write("faield"); conn.Close(); } } 复制代码 前台代码不用管. 3，新建一个Unity 3D项目,新建一个Javascript文件, 在Javascript文件上编写如下代码： var URL = "http://devmac.net/domino/rui/Default.aspx"; //提交的URL地址 static var return_data:String; var strname:String; var strpwd:String; var cls:boolean=false; var xx:Rect = Rect (20, 10, 150, 100); function OnGUI() { if(cls) xx = GUI.Window(1, xx, windowjj, "Window"); GUI.Label(Rect(10,10,80,20),"UserName:"); GUI.Label(Rect(10,30,80,20),"Userpass:"); strname=GUI.TextField(Rect(90,10,100,20),strname); strpwd=GUI.PasswordField(Rect(90,30,100,20),strpwd,"*"[0],25); //same as above, but for password if ( GUI.Button ( Rect (60, 60, 100, 20) , "Login" ) ){ //just a button Login(); } } function windowjj(windowID : int){ GUI.Label(Rect(55,25,50,20),return_data); if(GUI.Button(Rect(50,55,50,20),"Close")) cls=false;// } function Login() { var form = new WWWForm(); //创建一个WWWForm对象。 form.AddField( "name2", strname ); form.AddField("pwd",strpwd); var w:WWW=new WWW(URL,form); yield w; //we wait for the form to check the PHP file, so our game dont just hang cls=true; if (w.error != null) { //if there is an error, tell us return_data=w.error; } else { return_data=w.text; w.Dispose(); //clear our form in game } } 复制代码 4. 此代码放在主相机上。 5.最后在网上搜一个crossdomain.xml文件,自己写也行,把它放在挂有Asp.net网站的根目录下,这样就大功告成了. 6,导入到IPhone手机里也成功访问到数据库.
