  • 第4题:

    某留言系统采用ASP+Access开发,其后台管理登录页面如图4-1所示。

    图4-1

    【问题1】(9分)

    以下是该后台管理登录页面login.asp的部分代码,请仔细阅读该段代码,根据图4-1 将(1)~(9)的空缺代码补齐。

    <!--include file=“conn.asp”-->

    <!--include file=“md5.asp”-->

    <!--include file=“bbb.asp”-->

    <%

    If request.Form(“submit”)=“管理登录”Then

    user_name = request.Form(“ (1) ”)

    password = request.Form(“ (2) ”)

    verifycode = request.Form(“ (3) ”)

    If user name =“” Then

    Callinfoback(“用户名不能为空!”)

    End If

    ......

    Set (4) = server. CreateObject(“adodb.recordset”)

    sql = “select * from administrator (5) user_name = “&user_name&”and

    password = “&md5(password)””

    rs.Open (6) ,conn,1,1

    If (7) rs.EOF Then

    session(“user_name”)= user_name

    response.redirect“information.asp”

    Else

    Call infoback(“用户名或密码错误!”)

    End If

    End If

    <form. method=“post”action=“login.asp”id=“login”>

    <hl>管理员登录</hl>

    <label for=“user_name”>用户名:

    <input name=“user_name” type=“text” class=“user_name” id=“uname” size=“25”/>

    </label>

    <label for=“password“>密码:

    <input name=“password”type=“password”id=“pword” size=“25”/>

    </form>

    </body>

    </html>

    (1)~(9)备选答案如下:

    A.pword B.where C.uname D.vcode E.reset

    F.submit G.rs H.sql I. Not


    正确答案:

    request.form方法:获取客户端表单信息(通常是POST方法提交的表单)。

    user_namepasswordvarifycode为变量,分别用三个文本字段表单元素的ID结合request.form方法进行赋值。

    语句Set rs = server. CreateObject(“adodb.recordset”)为建立数据记录集实例。

    语句sql = select * from administrator where user_name = &user_name&andpassword = &md5password)””为定义一条带条件查询的SQL语句(用sql引用)。

    语句rs.Open sqlconn11 为定义以只读方式打开数据集记录。一般情况下,执行rs.open sql .conn是查询数据库中是否有符合该SQL语句的记录,如果记录存在那么rs.Eof=false,如果不存在那么rs.eof=trueif not rs.eof就是如果记录集指针没有到达最后一条记录之前,指针继续下移。

    【问题1】(9分,每空1分)

    (1)C或uname

    (2)A或pword

    (3)D或vcode

    (4)G或rs

    (5)B或where

    (6)H或sql

    (7)I或Not

    (8)E或reset

    (9)F或submit
