用ASP实现分级权限控制

本文实现的是一个帐务管理系统中分级权限的控制，程序使用ASP和javascript编写，在装有IIS4.0的win NT服务器上运行，速度快，易维护。

权限级别划分如下：

①、院长和财务科长：不能输入，可以无限制查询、统计；

②、副院长：不能输入，可以查询、统计其分管部门的帐务；

③、部门领导：不能输入，可以查询、统计本部门的帐务；

④、会计：能输入各部门的帐务（一个会计有时要做几个部门的帐），只能查询、统计自己输入的帐务。

涉及的数据库和字段如下

①、JK_USER数据库及字段：id(序列号),bmid（部门号）,username（用户名）,pwd（口令）,right（权限值）；

②、BM数据库及字段:id(序列号) ,bmid(部门号)；

③、JZPZ数据库及字段：id(序列号)，bm(部门)， zgs(子公司)，xmz(项目组)，xm（项目），sr（收入），zc(支出)，szfx(收支方向),szxs(收支形式),

rq(日期),jbr(经办人),lrr（录入人），szsm(收支说明)；

④、ZGS数据库及字段：id（序列号）,zgs（子公司）name（公司名）,bmid（部门编号）。

1．首先进行用户身份合法性验证

将用户提交的用户名和口令与数据库JK_USER中的字段对照对照，以确定其合法性，只有合法的用户（系统管理员为其开过户）才可以进入，合法用户有

四种权限级别，分别赋予“1”、“2”、“3”、“4”四种权限值。（程序略）。

2．凭证记帐（分级权限控制）

凭证记帐功能是专为会计人员服务的，其他人不可以使用，如以非会计人员身份进入凭证录入界面时，只有“查询记帐凭证”功能按钮可见，其它功能

按钮不可见。录入的凭证先存放在一个临时表里，称为“未记帐凭证库”，只有运行“凭证记帐”功能后才进入“凭证库”在“未记帐凭证库”中的凭证可以

修改。部分程序如下：

'非会计人员进入，不显示“凭证记帐”和“保存未记帐凭证”功能按钮

if (thisPage.firstEntered) then

if session("tright")<> "1" then

button1.hide

button2.hide

end if

'自动填写时间和操作人

Textbox7.value=year(date) & "-" & month(date) & "-" & day(date)

Textbox9.value =session("username")

set cnn1=server.CreateObject("adodb.connection")

set rst1=server.CreateObject("adodb.recordset")

cnn1.CursorLocation=3

cnn1.ConnectionTimeout =30

cnn1.Open "DSN=jky"

rst1.Open "select * from bm ",cnn1,1,1,adcmdtext

if rst1.RecordCount >0 then

RST1.MoveFirst

Id=rst1.Fields("id")

do while not rst1.EOF

Listbox3.addItem rst1.Fields("bmName"),cint(rst1.Fields("id"))

“Response.Write rst1.Fields("bmname") & rst1.Fields("id")

rst1.MoveNext

loop

end if

rst1.Close

rst1.Open "select zgsname from zgs where bmid=" & id,cnn1,1,1,adcmdtext

if rst1.RecordCount >0 then

rst1.MoveFirst

do while not rst1.EOF

Listbox4.addItem cstr(rst1.Fields("zgsname"))

rst1.MoveNext

loop

end if

rst1.Close

cnn1.close

call writerst

end if

end function

s=Listbox1.selectedIndex

Response.Write s

i=Listbox4.getCount()

do while i>-1

call Listbox4.removeItem(i)

set cnn2=server.CreateObject("adodb.connection")

set rst2=server.CreateObject("adodb.recordset")

cnn2.CursorLocation=3

cnn2.ConnectionTimeout =30

cnn2.Open"DSN=jky"

rst2.Open "select zgsName from zgs where bmid=" & id,cnn2,1,1,adcmdtext

if rst2.RecordCount >0 then

sub button2_onclick

set cnn5=server.CreateObject("adodb.connection")

cnn5.CursorLocation=3

cnn5.ConnectionTimeout =30

cnn5.Open"DSN=jky"

cnn5.Execute "insert into jzpz(bm,zgs,xmz,xm,sr,zc,szfx,szxs,rq,jbr,lrr,szsm) select bm,zgs,xmz,xm,sr,zc,szfx,szxs,rq,jbr,

lrr,szsm from wjzpz where lrr=“" & session("username") & "“"

cnn5.Execute "delete from wjzpz where lrr=“" & session("username") & "“"

end sub

3.数据查询（分级权限控制）

以凭证的字段为条件进行查询，在供选条件前有一方框供打“√”，其中“部门“条件必选（程序自动加上），部门内容由程序根据用户的权限自动

从数据库中调用相应值，分公司内容根据所属部门自动调整，部分程序如下：
