一、实现登录的思路：

1.添加系统CSS和JS

2.构建登录的Login.aspx的页面HTML

3.编写登录Ext.js的代码

4.编写CSS 实现登录与密码框前的小图标

5.实现登录验证码

6.实现登录的前后台编码

二、具体代码：

1.添加系统CSS和JS

<script type="text/javascript" src="/Web/Ext/adapter/ext/ext-base-debug.js"></script>

<script type="text/javascript" src="/Web/Ext/ext-all-debug.js"></script>

<script src="/Web/JavaScript/Common/Global.js" type="text/javascript"></script>

2.构建登录的Login.aspx的页面HTML

<body>

    <div id="hello-win" class="x-hidden">

        <div class="x-window-header">登录入口</div>

        <div id="hello-tabs">

        	    <img src="data:images/systemBanner.jpg"/>

        </div>

         <div id='loginInfo' style='color:red;padding-left:120px;'>

    请输入已经通过审核的用户名与密码进行登陆！

    </div>

    </div>

</body>

3.编写登录Ext.js的代码

  <script type="text/javascript">

        Ext.onReady(function () {

            Ext.BLANK_IMAGE_URL = "/ExtOA.Web/Ext/resources/images/default/s.gif";

            var loginForm = new Ext.FormPanel({

                el: "hello-tabs",

                id: "loginForm",

                name: "loginForm",

                border: false,

                //配置项

                items: {

                    //xtype可作为Ext控件的简写，都会对应一个Ext控件

                    xtype: "tabpanel",

                    //第一项

                    activeTab: 0,

                    defaults: { autoHeight: true, bodyStyle: "padding:10px" },

                    items: [

                        {

                            title: "管理员登录",

                            //显示对应的div

                            contentEl: "loginInfo",

                            //排列的方式

                            layout: "form",

                            defaults: { width: 230 },

                            //默认的类型

                            defaultType: "textfield",

                            if (win.getComponent("loginForm").form.isValid()) {

                                //进行提交

                                win.getComponent("loginForm").form.submit({

                                    url: "handler/CheckLogin.aspx",

                                    waitTitle: "提示",

                                     waitMsg: "正在登录验证,请稍候...",

                                      method: "POST",

                                      success: function (form,action) {

                                          var loginResult = action.result.success;

                                          if (loginResult) {

                                              window.location.href = action.result.href;

                                          } else {

                                              Ext.Msg.alert("提示",action.result.message);

                                          }

                                      },

                                      failure: function (form,action) {

                                          Ext.Msg.alert("提示", action.result.message);

                                          //失败得到图片的对象

                                          var imgSN = Ext.getDom("imgSnCode");

                                          if (imgSN)

                                          {

                                              //加参数

                                            imgSN.src="handler/VerifyCode.aspx?datetime=" + (new Date()).getTime();

                                          }

                                      },

                                });

                            }

                           // alert("确定");

                        }

                    },

                    {

                        text: "重置",

                        handler: function () {

                            //获取loginFrom的主建  或者直接获取

                            win.getComponent("loginForm").form.reset();

                          //  loginForm

                            //alert("重置");

                        }

                    }

                ]

            });

            //让窗体显示

            win.show();

            //得到验证码控件

            var db = Ext.getDom("validateCode");

            //得到父节点

            var db2 = Ext.get(db.parentNode);

            //用DomHelper得到getDom 的值

            db2.createChild([{ tag: "span", html: "   " }, { tag: "img", id: "imgSnCode",style:"cursor:pointer",title:"看不清楚？", src: "handler/VerifyCode.aspx", align: "absbottom" }]);

            //让验证码刷新

            var imgSN = Ext.get("imgSnCode");

            if (imgSN) {

                imgSN.on("click", function () {

                    this.dom.src = "handler/VerifyCode.aspx?datetime=" + (new Date()).getTime();

                });

            }

        })

    </script>

5.实现登录验证码

1.后台验证码的帮助类：


   /// <summary>

   /// 产生一个随机数

   /// </summary>

   /// <param name="codeCount"></param>

   /// <returns></returns>

    private string CreateRandomCode(int codeCount)

    {

        string allChar = "0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,w,x,y,z";

        string[] allCharArray = allChar.Split(',');

        string randomCode = "";

        int temp = -1;

        Random rand = new Random();

        for (int i = 0; i < codeCount; i++)

        {

            if (temp != -1)

            {

                rand = new Random(i * temp * ((int)DateTime.Now.Ticks));

            }

            int t = rand.Next(35);

            if (temp == t)

            {

                //不相等的话继续产生

                return CreateRandomCode(codeCount);

            }

            temp = t;

            randomCode += allCharArray[t];

        }

        return randomCode;

    }

    private void CreateImage(string checkCode)

    {

        //创建宽度

        int iwidth = (int)(checkCode.Length * 11.5);

        System.Drawing.Bitmap image = new System.Drawing.Bitmap(iwidth, 20);

        Graphics g = Graphics.FromImage(image);

        Font f = new System.Drawing.Font("Arial", 10, System.Drawing.FontStyle.Bold);

        Brush b = new System.Drawing.SolidBrush(Color.Blue);

        //g.FillRectangle(new System.Drawing.SolidBrush(Color.Blue),0,0,image.Width, image.Height);

        g.Clear(Color.White);

        g.DrawString(checkCode, f, b, 3, 3);

        System.IO.MemoryStream ms = new System.IO.MemoryStream();

        image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);

        //清空内容项

        Response.ClearContent();

        Response.ContentType = "image/Jpeg";

        //客户端输出二进制数据

        Response.BinaryWrite(ms.ToArray());

        g.Dispose();

        image.Dispose();

    }

2.前台js的调用：（动态产生图片）

   //得到验证码控件

            var db = Ext.getDom("validateCode");

            //得到父节点

            var db2 = Ext.get(db.parentNode);

            //用DomHelper得到getDom 的值

            db2.createChild([{ tag: "span", html: "   " }, { tag: "img", id: "imgSnCode", src: "handler/VerifyCode.aspx", align: "absbottom" }]);

3.后台核心代码：

1.指向的页面： （为aspx页面）
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="VerifyCode.aspx.cs" Inherits="VerifyCode" %>


 private void Page_Load(object sender, System.EventArgs e)

    {

        string checkCode = CreateRandomCode(4);//产生一个数字+字母组合的随机四位数

        Session["CheckCode"] = checkCode; //将此四位数保存至Session,供登录验证

        CreateImage(checkCode);//根据此验证码产生图片返回到调用端

    }

6.实现登录的前后台编码

前台：重置按钮：

  win.getComponent("loginForm").form.reset();

确认按钮：（通过Submit提交）

                           //判断是否通过验证

                            if (win.getComponent("loginForm").form.isValid()) {

                                //进行提交

                                win.getComponent("loginForm").form.submit({

                                    url: "handler/CheckLogin.aspx",

                                    waitTitle: "提示",

                                     waitMsg: "正在登录验证,请稍候...",

                                      method: "POST",

                                      success: function (form,action) {

                                          var loginResult = action.result.success;

                                          if (loginResult) {

                                              window.location.href = action.result.href;

                                          } else {

                                              Ext.Msg.alert("提示",action.result.message);

                                          }

                                      },

                                      failure: function (form,action) {

                                          Ext.Msg.alert("提示", action.result.message);

                                          //失败得到图片的对象

                                          var imgSN = Ext.getDom("imgSnCode");

                                          if (imgSN)

                                          {

                                              //加参数

                                            imgSN.src="handler/VerifyCode.aspx?datetime=" + (new Date()).getTime();

                                          }

                                      },

                                });

后台代码：CheckLogin.aspx

 string username = Request["staffName"].ToString();

        string password = Request["staffPwd"].ToString();

        string reqCheckCode = Request["validateCode"].ToString();

        //保存在session中的验证码

        string checkCode = Session["CheckCode"].ToString();

        //思路：先检查验证码是否正确，是否存在用户名，最后判断密码

        if (checkCode != reqCheckCode)

        {

            Response.Write("{success:false,message:'登录失败，您输入的验证码和系统产生的不一致，请重新输入!'}");

        }

        else {

            ExtOA.Biz.UserInfoBiz helper = new ExtOA.Biz.UserInfoBiz();

            ExtOA.Ent.UserInfo userinfo = helper.GetUserInfoByUserName(username);

            if (userinfo != null)

            {

                if (userinfo.PassWord == password)

                {
                    Session["CurrentUser"]==userinfo;

                    Response.Write("{success:true,href:'/Web/Manage/DeskTop/index.aspx',message:''}");

                }

                else

                {

                    Response.Write("{success:false,message:'登录失败,您输入的密码不正确，请与管理员联系!'}");

                }

            }

            else

            {

                Response.Write("{success:false,message:'登录失败,您的用户名尚未通过验证，请与管理员联系!'}");

            }

后台代码部分思路：

1.ExtOA.IDal添加一个新方法

2. ExtOA.SqlServerDal实现ExtOA.IDal方法

3.UserInfoBiz业务逻辑层中调用ExtOA.SqlServerDal中的方法

4.CheckLogin中调用UserInfoBiz

ExtOA.IDal：

 UserInfo GetUserInfoByUserName(string usernaem);

ExtOA.SqlServerDal：

   /// <summary>

        /// 根据用户名获取用户实体

        /// </summary>

        /// <param name="usernaem"></param>

        /// <returns></returns>

        public UserInfo GetUserInfoByUserName(string usernaem)

        {

            UserInfo result = null;

            string sql = "Get_UserInfo_By_UserName";

            using (System.Data.SqlClient.SqlConnection connection = new System.Data.SqlClient.SqlConnection(ConnectionString))

            {

                System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand(sql, connection);

                command.CommandType = System.Data.CommandType.StoredProcedure;

                //command.CommandTimeout = 0;

                System.Data.SqlClient.SqlParameter p_userName = command.Parameters.Add("@UserName", SqlDbType.VarChar);

                p_userName.Direction = ParameterDirection.Input;

                p_userName.IsNullable = false;

                p_userName.Value = usernaem;

                connection.Open();

                using (SqlDataReader dr = command.ExecuteReader())

                {

                    if (dr.Read())

                    {

                        result = new UserInfo();

                        result = PopulateUserInfoFromIDataReader(dr);

                    }

                    dr.Close();

                }

                command.Dispose();

                connection.Close();

            }

            return result;

        }

UserInfoBiz：

   /// <summary>

         /// 根据用户名获取用户的实体

         /// </summary>

         /// <param name="usernaem"></param>

         /// <returns></returns>

        public UserInfo GetUserInfoByUserName(string usernaem)

        {

            try

            {

                IUserInfoDR dal = UserInfoDal.Create(Config.Instance().Dal, Config.Instance().MyConnectstring);

                return dal.GetUserInfoByUserName(usernaem);

            }

            catch (Exception ex)

            {

                //log.Error("SetUserInfo err:",ex);

                return null;

            }
