.Net開發WAP

.Net開發WAP

選擇用ASP.NET開發,ASP.NET開發WAP站點,實在簡單,就是一個移動控件的運用,根本不用懂WML語法.唯一不同的,就是一個ASPX文件可以支持多個FORM,不同FORM之間可以切換,
最後ASP.NET根據訪問的設備,輸出不同的內容,
如果用IE訪問就輸出HTML,手機訪問,輸出WML,
不過在開發過程中也遇到了很多問題,一些問題總結如下:
1.模擬器選擇:
    WINWAP,
    M3Gate,
    UP.SDK4.0,(推薦)
    OPenWave 5.0 (測試時需要),
    OPenWave6.2, (IIS 6.0應用,IIS5.0可能顯示,但會有問題)
     CheckCom WAPBrowser 3.2
模擬器問題:
     ASP.NET把一些常有的模擬器,的配製信息用正則表達式寫在Machine.config裏
     在上述的模擬器中,我只有UP.SDK4.0,OPenWave 5.0,
他們只是一個公司的產品:
     需要下載,配製文件驅動更新:現在最新版本是:Device 4下載請到這裏下載:
http://www.microsoft.com/downloads/details.aspx?FamilyId=02FA15FE-40D9-4DCE-9BB1-4DD61A5B7CCB&displaylang=en
但是,即使驅動更新以後,還是一些設備不能訪問:
這時需要強制輸出WML:
在web.config
添加下面內容<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>

如果定義相關其它屬性可以完整的移動設置屬性:

具體屬性的意思可以考試MSDN:設備功能列表
ms-help://MS.MSDNQTR.2003FEB.2052/mwsdk/html/mwlrfDeviceCapabilitiesTable.htm

但這樣將給您在需要IE調試時帶來很大的不便
下面代碼將能解決IE和模擬器同時高度的問題（同樣將下面代碼加入system.web節點中）

    <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.鏈接:
在同一個aspx文件,使用Link控件的,#FORM來切換不同Form時在 OPenWave 5.0測試會出現錯誤!
建議在程序通過ActiveForm來做
3.亂碼:
     如果在開發過程出現亂碼,通過修改Web.Config
     <globalization
            requestEncoding="gb2312"
            responseEncoding="gb2312"
    />
4.取消移動設備緩存:

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

5.重定向
重定向通過
RedirectToMobilePage函數
不過使用過程中可能會出現一些問題
建議用Link控件來代替
