asp.net强制输出WML

ASP.NET WAP开发

选择用ASP.NET开发,ASP.NET开发WAP站点,实在简单,就是一个移动控件的运用,根本不用懂WML语法.唯一不同的,就是一个ASPX文件可以支持多个FORM,不同FORM之间可以切换,
最后ASP.NET根据访问的设备,输出不同的内容,
如果用IE访问就输出HTML,手机访问,输出WML,
不过在开发过程中也遇到了很多问题,一些问题总结如下:
1.模拟器选择:
    WINWAP,
    M3Gate,
    UP.SDK4.0,(推荐)
    OPenWave 5.0 (测试时需要),
    OPenWave6.2, (IIS 6.0应用,IIS5.0可能显示,但会有问题)
    CheckCom WAPBrowser 3.2
模拟器问题:
    ASP.NET把一些常有的模拟器,的配制信息用正则表达式写在Machine.config里
    在上述的模拟器中,我只有UP.SDK4.0,OPenWave 5.0,
他们只是一个公司的产品:
    需要下载,配制文件驱动更新:现在最新版本是:Device 4下载请到这里下载:
http://www.microsoft.com/downloads/details.aspx?FamilyId=02FA15FE-40D9-4DCE-9BB1-4DD61A5B7CCB&displaylang=en
但是,即使驱动更新以后,还是一些设备不能访问:
这时需要强制输出WML:
在web.config
添加下面内容<system.web>下

< browserCaps >
             < result  type ="System.Web.Mobile.MobileCapabilities, System.Web.Mobile, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
             < use  var ="HTTP_USER_AGENT" />
                    preferredRenderingType = "wml11"
                    preferredRenderingMime = "text/vnd.wap.wml"
                    preferredImageMime = "image/vnd.wap.wbmp"
</ browserCaps >

如果定义相关其它属性可以完整的移动设置属性:

具体属性的意思可以考试MSDN:设备功能列表
ms-help://MS.MSDNQTR.2003FEB.2052/mwsdk/html/mwlrfDeviceCapabilitiesTable.htm

但这样将给您在需要IE调试时带来很大的不便
下面代码将能解决IE和模拟器同时高度的问题（同样将下面代码加入system.web节点中）

    <browserCaps>
<result type="System.Web.Mobile.MobileCapabilities, System.Web.Mobile, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
<use var="HTTP_USER_AGENT"/>
<filter>
<case match="Unknown" with="%{browser}">
preferredRenderingType = "wml11"
preferredRenderingMime = "text/vnd.wap.wml"
preferredImageMime = "image/vnd.wap.wbmp"
type=Unknown
</case>
</filter>
</browserCaps>

2.链接:
 在同一个aspx文件,使用Link控件的,#FORM来切换不同Form时在 OPenWave 5.0测试会出现错误!
建议在程序通过ActiveForm来做
3.乱码:
    如果在开发过程出现乱码,通过修改Web.Config
    <globalization
            requestEncoding="gb2312"
            responseEncoding="gb2312"
    />
4.取消移动设备缓存:

  Page.Response.Expires  =   - 1 ;
   Response.CacheControl  =   " Public " ;

5.重定向
重定向通过
RedirectToMobilePage函数
不过使用过程中可能会出现一些问题
建议用Link控件来代替
