'----实现get请求的注入的拦截-----
dim sql_injdata,Sql_Inj,SQL_Get,Sql_Post,Sql_DATA
SQL_injdata = "'|and|exec|insert|select|delete|update|count|*|%|chr|mid|master|truncate|char|declare"
SQL_inj = split(SQL_Injdata,"|")
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 "<Script Language=JavaScript>alert('参数出错!'); history.back(-1)</Script>"
Response.end
end if
next

'----我们还要过滤post请求,所以我们还得继续考虑request.form,这个也是以数组形式存在的,我们只需要再进一次循环判断即可-----
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 "<Script Language=JavaScript>alert('参数出错!'); history.back(-1)</Script>"
