澳门新葡亰平台游戏网站如何修改被表单引用的ASP页面?

formhandler.asphtmlbody%Dim RequestMethod
RequestMethod = Request.ServerVariables(“REQUEST_ METHOD”)

1.日历

 


获取REQUEST_METHOD的数值,并把它存入本地的变量中.当Web页面被表单标识的Action参数调用时,REQUESTMETHOD的数值为Post.其余时候,
客商直接向浏览器中键入地址,刷新页面,或单击页面包车型客车叁个链接而调用页面,REQUEST_METHOD的数值是Get.If
RequestMethod = “GET” Then

检查REQUEST-METHOD的数值.If布局含有八个块代码,当条件为真时被施行,含有叁个Else块,条件为假时被执.刷新页面.

2.回顾的下拉菜单

搞好几点能够制止被注入:

%噢,您将来不能够刷新并浏览荧屏当前内容!如若想订正表单数据,请用后退键回到表单,或按提交重回.%Else
%应接光顾随风起舞!

 

  1. 尽也许不要再页面中或存款和储蓄进程中利用拼接的格局来生成 SQL 语句
  2. 连天数据库应当选择专项使用的数据库客户(并不是sa)
  3. 尽大概的利用 command 的措施来查询数据库。即使给 command
    扩大三个参数,那么,不论参数中富含怎么着字符都不会截断 SQL
    语句的,也就一纸空文注入攻击的恐怕了。

‘ 按下表单提交开关突显.

命令一

不过,终究使用拼接格局查询数据库的使用率仍旧相比高的,贴一段代码:

%= Request.Form(“Name”卡塔尔(قطر‎ %.P您最欢愉的国产小车:

%DIM favCaramrefavCaramre = Request.Form(“Caramre”)If favCaramre =
“OLYMPUS ” Then Response.Write(“噢,请稍候!”) Response.Write(“PA BOLYMPUS

这段代码保存成贰个独立的ASP文件,在也许存在注入的页面中含有就能够。
