防范SQL注入式攻击

%20or%20)(.*)$/gi;
 var e = re.test(url);
 if(e) {
  alert("地址中含有非法字符～");
  location.href="error.asp";
 }
//-->
<script>
[CODE END]

asp版的防范SQL注入式攻击代码～：
[CODE START]
<%
On Error Resume Next
Dim strTemp

If LCase(Request.ServerVariables("HTTPS")) = "off" Then
 strTemp = "http://"
Else
 strTemp = "https://"
End If

strTemp = strTemp & Request.ServerVariables("SERVER_NAME")
If Request.ServerVariables("SERVER_PORT") <> 80 Then strTemp = strTemp & ":" & Request.ServerVariables("SERVER_PORT")

strTemp = strTemp & Request.ServerVariables("URL")

If Trim(Request.QueryString) <> "" Then strTemp = strTemp & "?" & Trim(Request.QueryString)

strTemp = LCase(strTemp)

If Instr(strTemp,"select%20") or Instr(strTemp,"insert%20") or Instr(strTemp,"delete%20from") or Instr(strTemp,"count(") or Instr(strTemp,"drop%20table") or Instr(strTemp,"update%20") or Instr(strTemp,"truncate%20") or Instr(strTemp,"asc(") or Instr(strTemp,"mid(") or Instr(strTemp,"char(") or Instr(strTemp,"xp_cmdshell") or Instr(strTemp,"exec%20master") or Instr(strTemp,"net%20localgroup%20administrators")  or Instr(strTemp,":") or Instr(strTemp,"net%20user") or Instr(strTemp,"'") or Instr(strTemp,"%20or%20") then
 Response.Write "<script language='javascript'>"
 Response.Write "alert('非法地址！！');"
 Response.Write "location.href='error.asp';"
 Response.Write "<script>"
End If
%>
[CODE END]

 

以下是较为简单的防范方法，这些都是大家比较熟悉的方法，我就是转帖过来。希望能给你一点帮助~

主要是针对数字型的变量传递：

id = Request.QueryString("id")

If Not(isNumeric(id)) Then

   Response.Write "非法地址~"

   Response.End

End If

以下是正常显示代码~
