asp常用函数
1.放注入函数
sub aspsql()
SQL_injdata = "'|;|and|exec|insert|select|delete|update|count|*|%|chr|mid|master|truncate|char|declare"
SQL_inj = split(SQL_Injdata,"|")
If Request.Form<>"" Then
For Each Sql_Post In Request.Form
For SQL_Data=0 To Ubound(SQL_inj)
if instr(Request.Form(Sql_Post),Sql_Inj(Sql_DATA))>0 Then
response.write "<mce:script language='javascript'><!--
"
response.write "alert('网站安全提示：请不要在参数中包含非法字符！');"
response.write "location.href='javascript:history.go(-1)';"
response.write "
// --></mce:script>"
response.end
end if
next
next
end if
If Request.QueryString<>"" Then
For Each SQL_Get In Request.QueryString
For SQL_Data=0 To Ubound(SQL_inj)
if instr(Request.QueryString(SQL_Get),Sql_Inj(Sql_DATA))>0 Then
response.write "<mce:script language='javascript'><!--
"
response.write "alert('网站安全提示：请不要在参数中包含非法字符！');"
response.write "location.href='javascript:history.go(-1)';"
response.write "
// --></mce:script>"
response.end
end if
next
Next
end If
end sub
2.会员名是否含有汉字
function jc(s)
r=true
str="0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIGKLMNOPQRSTUVWXYZ"
for i=1 to len(s)
w=mid(s,i,1)
if instr(str,w)=0 then
r=false
end if
next
jc=r
end function
3.过滤字符中的特殊字符
Function inHTML(str)
Dim sTemp
sTemp = str
inHTML = ""
If IsNull(sTemp) = True Then
Exit Function
End If
sTemp = Replace(sTemp, "&", "&")
sTemp = Replace(sTemp, "<", "<")
sTemp = Replace(sTemp, ">", ">")
sTemp = Replace(sTemp, Chr(34), """)
inHTML = sTemp
End Function
4.'拒绝夸站提交代码
function postFormfrom()
server_v1=Cstr(Request.ServerVariables("HTTP_REFERER"))
server_v2=Cstr(Request.ServerVariables("SERVER_NAME"))
if mid(server_v1,8,len(server_v2))<>server_v2 then
CuBox "你提交的路径有误，禁止从站点外部提交数据请不要乱该参数！",1,""

存储进程就是作为可执行对象存放在数据库中的一个或多个SQL命令。
定义总是很抽象。存储进程其实就是能完成一定操作的一组SQL语句，只不过这组语句是放在数据库中的(这里我们只谈SQL SERVER)。如果我们通过创建存储进程以及在ASP中调用存储进程，就可以避免将SQL语句同ASP代码混杂在� ......
