asp.net wap开发心得
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
evice 4下载请到这里下载:

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:
<browserCaps>
<result type=”System.Web.Mobile.MobileCapabilities, System.Web.Mobile, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a”/>

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
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
