新老客户大回馈,云服务器低至5折

下面是以Serv-U 6.0和Sql Server 2000相结合的演示。

建表Sql 语句:

CREATE TABLE [groupaccounts] (
[id] int IDENTITY (1,1) PRIMARY KEY,
[Index] int Default 0,
[Name] nVarChar(50) default '',
[Notes] nVarChar(255) default ''
)
CREATE INDEX [Name] on [groupaccounts]([Name] )

CREATE TABLE [groupdiraccess] (
[id] int IDENTITY PRIMARY KEY,
[Access] nVarChar(255) default '',
[Index] int Default 0,
[Name] nVarChar(50) default ''
)
CREATE INDEX [Name] on [groupdiraccess]([Name] )

CREATE TABLE [groupipaccess] (
[id] int IDENTITY PRIMARY KEY,
[Access] nVarChar(255) default '',
[Index] int Default 0,
[Name] nVarChar(50) default ''
)
CREATE INDEX [Name] on [groupipaccess]([Name] )


CREATE TABLE [useraccounts] (
[id] int IDENTITY PRIMARY KEY,
[Access] nVarChar(255) default '',
[AlwaysLogin] int Default 0,
[ChangePass] int Default 0,
[Disable] int Default 0,
[Expirationtype] int Default 0,
[Expiration] datetime Default '1980-1-1',
[Groups] nVarChar(50) default '',
[HideHidden] int Default 0,
[HomeDir] nVarChar(100) default '',
[idleTimeOut] int Default 0,
[LogMesfile] nVarChar(100) default '',
[MaxIp] int Default -1,
[MaxSpeedDown] decimal Default 0,
[MaxSpeedUp] decimal Default 0,
[MaxUsers] int Default -1,
[Name] nVarChar(50) default '',
[Needsecure] int Default 0,
[Notes] nVarChar(255) default '',
[PassType] int Default 0,
[Password] nVarChar(50) default '',
[Privilege] int Default 0,
[QuotaCurrent] decimal Default 0,
[QuotaEnable] int Default 0,
[QuotaMax] decimal Default 0,
[RatioCredit] decimal Default 0,
[RatioDown] int Default 0,
[RatioType] int Default 0,
[RatioUP] int Default 0,
[RelPaths] int Default 0,
[SessionTimeOut] int Default 0,
[SkeyValues] nVarChar(50) default ''
)
CREATE INDEX [Name] on [useraccounts]([Name] )

CREATE TABLE [userdiraccess] (
[id] int IDENTITY PRIMARY KEY,
[Access] nVarChar(255) default '',
[Index] int Default 0,
[Name] nVarChar(50) default ''
)
CREATE INDEX [Name] on [userdiraccess]([Name] )

CREATE TABLE [useripaccess] (
[id] int IDENTITY PRIMARY KEY,
[Access] nVarChar(255) default '',
[Index] int Default 0,
[Name] nVarChar(50) default ''
)
CREATE INDEX [Name] on [useripaccess]([Name] )

ServUDaemon.ini中的ODBC信息:
ODBCSource=Serv-U||
ODBCTables=useraccounts|groupaccounts|userdiraccess|groupdiraccess|useripaccess|groupipaccess
ODBCColumns=Name|Password|SkeyValues|HomeDir|LogMesfile|Access|Disable|Needsecure|RelPaths|HideHidden|AlwaysLogin|ChangePass|QuotaEnable|MaxIp|MaxSpeedUp|MaxSpeedDown|MaxUsers|idleTimeOut|SessionTimeOut|RatioUP|RatioDown|RatioCredit|QuotaCurrent|QuotaMax|Expiration|Privilege|PassType|RatioType|Groups|Notes|Index


我们利用Serv-U的obdc功能,可以把FTP用户信息存在数据库中,这样对Web操作方便了很多,下面是在线更改密码的列子,数据库为Access,表和字段的设计请参考Serv-U的帮助文件。

加密算法为随机码与MD5 32 位加密,例如:
两个随机字母:ab
用户输入密码:123456
生成的密码为:ab MD5(ab123456)

补充:md5返回为32位的大写字符,附md5.asp

提示:代码仅实现更改密码的功能,并不一定完全符合或达到您的需求。

<!--#include file='conn.asp'-->
<!--#include file='include/md5.asp'-->
<%
dim act,UserName,OldPassword,NewPassword,reNewPassword
act = Request.form("act")
if act = "update" then

UserName = Request.form("UserName")
OldPassword = Request.form("OldPassword")
NewPassword = Request.form("NewPassword")
reNewPassword = Request.form("reNewPassword")
UserName = Replace(UserName,"'","'")

if len(UserName)<1 or len(OldPassword)<1 or len(NewPassword)<1 or len(reNewPassword)<1 then
alert("表单没有填写完整")
end if

if trim(NewPassword)<>trim(reNewPassword) then
alert("密码与确认密码不一样")
end if

Sql0 = "select top 1 name,[password] from [useraccounts] where name = '"& UserName &"'"
set rs0 = conn.execute(Sql0)
if rs0.eof and rs0.bof then
alert("用户名不存在")
else
dbname = rs0("name")
dbpassword = rs0("password")
end if

cdbpassword = left(dbpassword,2) & md5(left(dbpassword,2) & OldPassword)

if trim(cdbpassword) <> trim(dbpassword) then
alert("密码错误")
else
rndstr = MyRandc(2) '两位随机字母
newdbpassword = rndstr & md5(rndstr & NewPassword)
sql2 = "update [useraccounts] set [password] = '"& newdbpassword &"' where name='"& UserName &"'"
conn.execute(sql2)
alert("密码已经更改,可能要几钟后才能生效")
end if
end if

function alert(x)
response.write "<script language='JavaScript'>alert('"& replace(x,"""","\""") &"');history.go(-1);</script>"
conn.close
set conn = nothing
response.end
end function

function MyRandc(n)'生成随机字符,n为字符的个数
