补充 宝玉 之《URL欺骗之以假乱真!》之 POST 方法提交数据 之 处理!
補(bǔ)充 寶玉 之《URL欺騙之以假亂真!》之 POST 方法提交數(shù)據(jù) 之 處理!
(之乎者也,怪別扭的!)
我們首先搭建一個(gè)環(huán)境:
IIS 代理一下 Resin 下的 jsp 頁(yè)面! (Resin 乃是 Java 應(yīng)用服務(wù)器)
1.Resin 獲取:
http://www.caucho.com/download/resin-2.1.16.zip
下載后解壓某目錄,如:
E:/Resin/resin-2.1.16/
2.配置 Resin? (Java SDK 的配置就不贅述)
用文本編輯器打開(kāi):
E:/Resin/resin-2.1.16/conf/resin.conf
<http port='8080'/>
可配置端口,resin 默認(rèn)的是 8080 !
如果可用就不改!
<welcome-file-list>simplepost.jsp ,index.xtp, index.jsp, index.html </welcome-file-list>
可配置默認(rèn)歡迎頁(yè)面!
3.在 E:/Resin/resin-2.1.16/webapps/ 下創(chuàng)建新目錄 test:
編寫(xiě) E:/Resin/resin-2.1.16/webapps/test/index.jsp 并保存!
E:/Resin/resin-2.1.16/webapps/test/? 就是一個(gè) Application
<%@ page import='java.util.*'%>
<HTML>
<head>
<title>test</title>
</head>
<h1>Form Values:</h1>
<table>
<%
Enumeration e = request.getParameterNames();
while (e.hasMoreElements())
{
?String name = (String) e.nextElement();
?String[] values = (String[]) request.getParameterValues(name);
?%>
?<tr><td>
?<%= name %><td><%= values[0] %>
?<%
?if (values.length > 1)
?{
??for (int i = 1; i < values.length; i++)
??{
???%>,<%= values[i] %><%
??}
?}
}
%>
</table>
<form action='http://localhost' method='post'>
<input name='Comment' type="text" value="<%= request.getParameter("Comment") %>">
<input name='Comment2' type="text" value="<%= request.getParameter("Comment2") %>">
<input type=submit>
</form>
</body>
</HTML>
4.編寫(xiě) C# Openlab.UrlCheat.cs : (修改寶玉的代碼基礎(chǔ)上完成POST操作的處理)
//Openlab.UrlCheat.cs
//命令行編譯: csc /t:library Openlab.UrlCheat.cs
//生成的 Openlab.UrlCheat.dll 存放在 IIS 主目錄下建一個(gè) bin 目錄!
//如: C:/Inetpub/wwwroot/bin/Openlab.UrlCheat.dll
namespace Openlab.UrlCheat

?<system.web>
??<compilation defaultLanguage="c#" debug="true" />
??<httpHandlers>
???<add verb="*" path="*.gif" type="Openlab.UrlCheat.Redirect, Openlab.UrlCheat" />
???<add verb="*" path="*.jpg" type="Openlab.UrlCheat.Redirect, Openlab.UrlCheat" />
???<add verb="*" path="*.jpeg" type="Openlab.UrlCheat.Redirect, Openlab.UrlCheat" />
???<add verb="*" path="*.rar" type="Openlab.UrlCheat.Redirect, Openlab.UrlCheat" />
???<add verb="*" path="*.zip" type="Openlab.UrlCheat.Redirect, Openlab.UrlCheat" />
???<add verb="*" path="*.webinfo" type="System.Web.HttpForbiddenHandler"/>
???<add verb="GET" path="*" type="Openlab.UrlCheat.WebResponse, Openlab.UrlCheat" />
???<add verb="POST" path="*" type="Openlab.UrlCheat.WebResponse, Openlab.UrlCheat" />
??</httpHandlers>
?</system.web>
?<appSettings>
??<!-- 您可以修改這個(gè)域名 -->
??<add key="Domain" value="http://localhost:8080/test/" />
?</appSettings>
</configuration>
5.運(yùn)行 Resin 及 IIS
E:/Resin/resin-2.1.16/bin/httpd.exe
6.在 IE 地址欄訪(fǎng)問(wèn): http://localhost
提交一些數(shù)據(jù)測(cè)試!看看回顯是否正確?!
我測(cè)的夠慢的!
另外寶玉和我都沒(méi)考慮替換 href? 的 url 處理!
