近段時間由于修改一個asp程序(有SQL注入漏洞)，在網上找了很多相關的一些防范辦法，都不近人意，所以我將現在網上的一些方法綜合改良了一下，寫出這個ASP函數，供大家參考。

以下是引用片段：
Function SafeRequest(ParaName) 
Dim ParaValue 
ParaValue=Request(ParaName)
if IsNumeric(ParaValue) = True then
SafeRequest=ParaValue
exit Function
elseIf Instr(LCase(ParaValue),"select ") > 0 or Instr(LCase(ParaValue),"insert ") > 0 or Instr(LCase(ParaValue),"delete from") > 0 or Instr(LCase(ParaValue),"count(") > 0 or Instr(LCase(ParaValue),"drop table") > 0 or Instr(LCase(ParaValue),"update ") > 0 or Instr(LCase(ParaValue),"truncate ") > 0 or Instr(LCase(ParaValue),"asc(") > 0 or Instr(LCase(ParaValue),"mid(") > 0 or Instr(LCase(ParaValue),"char(") > 0 or Instr(LCase(ParaValue),"xp_cmdshell") > 0 or Instr(LCase(ParaValue),"exec master") > 0 or Instr(LCase(ParaValue),"net localgroup administrators") > 0  or Instr(LCase(ParaValue)," and ") > 0 or Instr(LCase(ParaValue),"net user") > 0 or Instr(LCase(ParaValue)," or ") > 0 then
 Response.Write "<script language='javascript'>"
 Response.Write "alert('非法的請求!');"  '發現SQL注入攻擊提示信息
 Response.Write "location.發現SQL注入攻擊轉跳網址
 Response.Write "<script>"
 Response.end
else
SafeRequest=ParaValue
End If
End function

使用SafeRequest函數替換你的Request
