初识 asp.net内置对象之Request对象

Request对象

Request对象用于检索从浏览器向服务器所发送的请求信息。它提供对当前页请求的访问,包括标题,Cookie,客户端证书等等。它也与HTTP协议的请求消息对应。

Request对象常用属性

属性
applicationPath获取服务器上ASP.NET虚拟应用程序的根目录路径
Browser获取或者设置有关在请求的客户端浏览器的功能信息
ContertLength指定客户端发送的内容长度
Cookies获取客户端发送的Cookie集合
FilePath获取当前请求的虚拟路径
Files获取采用多部分MIME格式的由客户端上载的文件集合
Form获取窗体变量集合
Item从Cookies, From, QueryString或ServerVariables集合中获取指定的对象
Params获取QueryString,Form,ServerVariables和Coockies项的组合集合
Path获取当前请求的虚拟路径
QueryString获取HTTP查询字符串变量集合
UserHostAddress获取远程客户端ip主机地址
UserHostName获取远程客户端DNS名称

Request常用方法

方法
MapPath将请求的URL中的虚拟路径映射到服务器上的物理路径
SaceAs将HTTP请求保存到磁盘

1.获取页面间传送的值

Request对象只要通过Params属性和QueryString属性获取页面间的传值。

下面继续上个简单的实验例子试试,我新建立一个RequestO.aspx页面,该页面就负责把信息传递给目标页面,所以放一个按钮简单演示下,代码如下:
