用户登录之asp.net cookie的写入、读取与操作

标签：style   blog   class   code   c   java   

页面前面：

"login" runat="server">
            class="log_title">账号（昵称）：class="log_input" runat="server" id="t_LogName" name="t_LogName" type="text" placeholder="请输入账号（昵称）" />
            class="log_title">密码：class="log_input" runat="server" id="t_LogPass" name="t_LogPass" type="password" placeholder="请输入密码" />
            "Button1" runat="server" Text="登陆" OnClick="Button1_Click" CssClass="button"
                EnableTheming="False" />
            "Button2" runat="server" CssClass="button" Text="注册" PostBackUrl="~/regist.aspx">
        

        
"logstate" runat="server" visible="false">欢迎您："uesrName" runat="server">"server" onserverclick="out_click">退出

要引入的样式：

#login { top:0; left: 0; width:580px;height:25px;background:pink;position: relative;float:left}
.button { height: 25px;font-size: 14px; background-color: #0998ff; color: #FFF;padding:3px 12px 5px 12px;border: 0px; vertical-align: middle;margin-left:5px;float:left; }
    .button:hover{ background-color: #6699FF;color:#000;cursor:pointer }
    .log_input{background-color:#FFF; border:1px solid #d5cfc2;width:130px;height:23px;  font-size:14px;vertical-align:middle;float:left}
    .log_title{width:90px; display:inline-block; text-align:right;line-height:25px; float:left;color:#FFF;}
#Head_logstate {/*width:200px;*/height:25px;color:#FFF;font-size:14px;line-height: 25px;/*background:blue;*/float:left;position: relative;}
    #Head_logstate span { color:#f00;font-weight:800;margin-right:20px}
    #Head_logstate a {height:25px;font-size: 14px; background-color: #0998ff; color: #FFF;padding:0 12px 0 12px;border: 0px; vertical-align: middle;float:right}
    #Head_logstate a:hover{ background-color: #6699FF;color:#000;cursor:pointer }

说明一下，应该是我把这个放在控件Head里，所以引入页面的时候，

logstate这个样式找不到，后来，我就改是

#Head_logstate，才显示正常，而在控件里div的样式还是用的

 
"logstate" runat="server" visible="false">....
控件的cs核心代码：


protected string mynames;
    protected string myID;
    protected void Page_Load(object sender, EventArgs e)
    {
        
        if (!IsPostBack) {
            HttpCookie cookie = Request.Cookies["nickname"];            
            if (cookie != null) {
                mynames = cookie.Value;
                GetLogin();
            }        
            
        }  
    }




protected void Button1_Click(object sender, EventArgs e) {
        string name = t_LogName.Value.Trim();
        string pw = t_LogPass.Value.Trim();        
        if (name.IndexOf("‘") > 0 || name.IndexOf("--") > 0) {
            HelperJS.Show(this.Page, "账号（昵称）存在非法字符!");
            return;
        }
        if (name != string.Empty && pw != string.Empty) {
            //检查用户名密码   
            DataTable dt = HelperExecuteSql.Query("select ID,nickname,pw from _user where nickname=‘" + name + "‘ and pw =‘" + pw + "‘").Tables[0];
            if (dt.Rows.Count > 0) {
                myID = dt.Rows[0]["ID"].ToString(); 
                //Session["nickname"] = name;        
                //Session["ID"] = Convert.ToInt32(dt.Rows[0][0].ToString());
                //uesrName.Text = dt.Rows[0]["nickname"].ToString();
                if (Request["ReturnUrl"] == null || Request["ReturnUrl"] == "") {    
                    string nowtime = DateTime.Now.ToString(); //获取当前时间
                    HttpCookie cookie = new HttpCookie("nickname", HttpUtility.UrlEncode(name));//获取用户的用户名
                    cookie.Expires = DateTime.Now.AddHours(2);//设置cookie过期时间为2小时后
                    Response.Cookies.Add(cookie);//将cookie写入客户端
                    HttpCookie cookie1 = new HttpCookie("nowTime", nowtime);
                    cookie1.Expires = DateTime.Now.AddHours(2);//设置cookie过期时间为2小时后
                    Response.Cookies.Add(cookie1);//将cookie1写入客户端
                    HttpCookie cookie2 = new HttpCookie("ID", myID);//获取用户的ID
                    Response.Cookies.Add(cookie2);//将cookie2写入客户端
                    Response.Write(" "); //刷新
                }
                else {
                    Server.Transfer(Request["ReturnUrl"]);
                }

            }
            else {
                HelperJS.Show(this.Page, "用户名或密码不正确!");
            }
        }
        else {
            HelperJS.Show(this.Page, "用户名或密码不能为空!");
        }
    }

    protected void out_click(object sender, EventArgs e)     //退出
   {
        Response.Cookies["nickname"].Expires = DateTime.Now;//cookie将马上过期        
        login.Visible = true;
        logstate.Visible = false;        
        Response.Write(" "); //刷新
    }
