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。本文出自【狗刨学习网】
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. |
