asp.net登录不了

问题描述

在adminsys文件夹里面，有个Default.aspx文件，是登录入口，输入用户名跟密码老是提示“用户名密码错误，登录失败”不知道什么问题，查看了数据库里面Admin表的用户名和密码，发现我输入的用户名跟密码都是没错的，请高手帮忙啊！(1)/adminsys/Default.aspx代码如下：<%@PageLanguage="C#"AutoEventWireup="true"CodeFile="Default.aspx.cs"Inherits="Adminsys_Default"%><htmlxmlns="http://www.w3.org/1999/xhtml"><headrunat="server"><title>后台登录</title><linkhref="../Adminsys/ML_style.css"rel="stylesheet"type="text/css"/></head><bodystyle="background-image:none"><formid="form1"runat="server"><divstyle="text-align:center;margin-top:100px;"><tablestyle="width:424px;height:293px;"border="0"cellpadding="0"cellspacing="0"><tr><tdstyle="width:429px;height:28px;background:url(images/we_1.gif);color:White;"valign="bottom"align="left"><strong>&nbsp;&nbsp;&nbsp;<asp:LabelID="lbl_Title"runat="server"Text=""></asp:Label></strong></td></tr><tr><tdstyle="height:126px;width:429px;"align="center"><asp:ImageID="adImg"runat="server"ImageUrl="images/we_2.gif"/></td></tr><tr><tdstyle="height:119;background:url(images/we_3.gif);width:429px"align="center"><tablewidth="100%"border="0"cellpadding="3"cellspacing="0"><tr><tdvalign="middle"style="width:128px;height:24px;"align="right"><b>用户名：</b></td><tdvalign="middle"align="left"><asp:TextBoxID="txt_username"runat="server"Style="border-right:#7b9fbe1pxsolid;border-top:#7b9fbe1pxsolid;font-size:12px;background:#f9f9f9;border-left:#7b9fbe1pxsolid;width:120px;border-bottom:#7b9fbe1pxsolid;height:18px"></asp:TextBox><asp:RequiredFieldValidatorID="valrUserName"runat="server"ErrorMessage="请输入管理员用户名！"ControlToValidate="txt_username"></asp:RequiredFieldValidator></td></tr><tr><tdvalign="middle"align="right"style="height:24px;width:128px;"><b>密码：</b></td><tdvalign="middle"align="left"><asp:TextBoxID="txt_pwd"runat="server"Style="border-right:#7b9fbe1pxsolid;border-top:#7b9fbe1pxsolid;font-size:12px;background:#f9f9f9;border-left:#7b9fbe1pxsolid;width:120px;border-bottom:#7b9fbe1pxsolid;height:18px"TextMode="Password"></asp:TextBox><asp:RequiredFieldValidatorID="valrPWD"runat="server"ControlToValidate="txt_pwd"ErrorMessage="请输入管理员密码！"></asp:RequiredFieldValidator></td></tr><tr><tdvalign="middle"align="right"style="height:24px;width:128px;"><b>验证码：</b></td><tdvalign="middle"align="left"><asp:TextBoxID="txt_ValidateNum"runat="server"Style="border-right:#7b9fbe1pxsolid;border-top:#7b9fbe1pxsolid;font-size:12px;background:#f9f9f9;border-left:#7b9fbe1pxsolid;width:60px;border-bottom:#7b9fbe1pxsolid;height:18px"></asp:TextBox>&nbsp;&nbsp;<asp:ImageID="ValidateNumber"runat="server"ImageUrl="~/Adminsys/chkcode/Image.aspx"ImageAlign="AbsMiddle"/><asp:RequiredFieldValidatorID="valrCode"runat="server"ControlToValidate="txt_ValidateNum"ErrorMessage="请输入验证码！"></asp:RequiredFieldValidator></td></tr><tr><tdvalign="middle"colspan="2"align="center"style="height:30px"><asp:ButtonID="btnSub"runat="server"Text="登录"OnClick="btnSub_Click"/></td></tr></table></td></tr><tr><tdstyle="width:429px"align="center"><asp:ImageID="Image1"runat="server"ImageUrl="~/Adminsys/images/we_5.gif"/></td></tr></table></div></form></body></html>(2)/adminsys/Default.aspx.cs文件（包含“登录”控件）代码如下：usingSystem;usingSystem.Data;usingSystem.Configuration;usingSystem.Collections;usingSystem.Web;usingSystem.Web.Security;usingSystem.Web.UI;usingSystem.Web.UI.WebControls;usingSystem.Web.UI.WebControls.WebParts;usingSystem.Web.UI.HtmlControls;usingSystem.Data.SqlClient;publicpartialclassAdminsys_Default:System.Web.UI.Page{protectedvoidPage_Load(objectsender,EventArgse){if(!IsPostBack){lbl_Title.Text=Page.Title=Convert.ToString(Application["siteName"])+"后台管理系统";}}protectedvoidbtnSub_Click(objectsender,EventArgse){stringuname=txt_username.Text.ToString();stringpwd=txt_pwd.Text.ToString();stringvalidateNum=txt_ValidateNum.Text.ToString();if(validateNum==(string)Session["CheckCode"]){string[]userInfo=admin.login(uname,pwd);if(userInfo[2].Equals(pwd)){Session["userID"]=userInfo[0];Session["userName"]=userInfo[1];Session["pwd"]=userInfo[2];Response.Redirect("admin_main.aspx");}else{Response.Write(jaylee.Msg("","用户名密码错误，登录失败！"));}}else{Response.Write(jaylee.Msg("","验证码输入错误！"));}}}

解决方案

解决方案二：
string[]userInfo=admin.login(uname,pwd);admin.login返回的是什么？if(userInfo[2].Equals(pwd))这个判断是正确的吗？

你是不是在web.config中添加了权限设置啊？如果是请加FormsAuthentication.RedirectFromLoginPage(this.txtUserName.Text,false);退出时加System.Web.Security.FormsAuthentication.SignOut();
解决方案七：
亲，你这码发的，让人看的很蛋疼啊
解决方案八：
排个版啊
解决方案九：
你传过来的参数值能取到吗？代码看得有些乱
解决方案十：
引用1楼的回复:

string[]userInfo=admin.login(uname,pwd);admin.login返回的是什么？if(userInfo[2].Equals(pwd))这个判断是正确的吗？

这个我也看不太懂，还请高手相助啊！
解决方案十一：
引用7楼的回复:

排个版啊

好的，这个是我下载下来的模版
解决方案十二：
引用8楼的回复:

你传过来的参数值能取到吗？代码看得有些乱

附件发不了，怎么才能把整个站点文件发给您看看呢？
解决方案十三：
OleDbDataReaderdr=(OleDbDataReader)OleDbHelper.ExecuteReader(CommandType.Text,"select*fromAdminwhereusername='"+jaylee.replacesql(uname).ToString()+"'andpassword='"+jaylee.to32MD5(jaylee.replacesql(pwd).ToString()).ToString()+"'");你的OleDbHelper里面没有定义ExecuteReader(CommandTypecmdType,Stringsql)的方法啊你应该写成OleDbDataReaderdr=(OleDbDataReader)OleDbHelper.ExecuteReader(CommandType.Text,"select*fromAdminwhereusername='"+jaylee.replacesql(uname).ToString()+"'andpassword='"+jaylee.to32MD5(jaylee.replacesql(pwd).ToString()).ToString()+"'",null);啊
解决方案十四：
另外你打印出去数据库中去查，能查到数据吗System.Web.HttpContext.Current.Response.Write("select*fromAdminwhereusername='"+jaylee.replacesql(uname).ToString()+"'andpassword='"+jaylee.to32MD5(jaylee.replacesql(pwd).ToString()).ToString()+"'");
解决方案十五：
引用5楼的回复:

你是不是在web.config中添加了权限设置啊？如果是请加FormsAuthentication.RedirectFromLoginPage(this.txtUserName.Text,false);退出时加System.Web.Security.FormsAuthentication.SignOut();

这个是我下载下来的模版，怎么看是不是添加了权限设置呢？
其他方案：
引用13楼的回复:

另外你打印出去数据库中去查，能查到数据吗System.Web.HttpContext.Current.Response.Write("select*fromAdminwhereusername='"+jaylee.replacesql(uname).ToString()+"'andpassword='"+jaylee.to32MD5(jaylee.……

我用Access打开数据库，里面是有对应的用户名跟密码的
其他方案：
估计密码加密了的原因！！
其他方案：
引用16楼的回复:

估计密码加密了的原因！！

我也有想过这个问题，但我对这个还不熟，不知道怎么改，请赐教
其他方案：
引用12楼的回复:

OleDbDataReaderdr=(OleDbDataReader)OleDbHelper.ExecuteReader(CommandType.Text,"select*fromAdminwhereusername='"+jaylee.replacesql(uname).ToString()+"'andpassword='"+jaylee.to32MD5(jayle……

改了，还是不行啊
其他方案：
System.Web.HttpContext.Current.Response.Write("select*fromAdminwhereusername='"+jaylee.replacesql(uname).ToString()+"'andpassword='"+jaylee.to32MD5(jaylee.replacesql(pwd).ToString()).ToString()+"'");去数据库中手工查询看有结果吗
其他方案：
跟踪下if(dr["password"].ToString()==jaylee.to32MD5(jaylee.replacesql(pwd).ToString()).ToString())看看她们数据是什么？
其他方案：
引用19楼的回复:

System.Web.HttpContext.Current.Response.Write("select*fromAdminwhereusername='"+jaylee.replacesql(uname).ToString()+"'andpassword='"+jaylee.to32MD5(jaylee.replacesql(pwd).ToString()).ToSt……

嗯，有结果
其他方案：
引用20楼的回复:

跟踪下if(dr["password"].ToString()==jaylee.to32MD5(jaylee.replacesql(pwd).ToString()).ToString())看看她们数据是什么？

怎么跟踪呢，我菜鸟，不明白啊
其他方案：
设置断点
其他方案：
你登陆方法加密了账号和密码，在数据库里的数据没有加密。所以虽然你输入的和数据库的一样，但经过加密后就不一样了。所以就会登录失败。添加方法和登陆方法都要将密码加密。这样才能保持一致。
其他方案：
蛋疼的代码！！！！！！！！！！
