近來,用MVC5開發自己的一個小網站.網上租用了一個小空間(虛擬主機),可選.net版本為2.0 3.0 3.5 4.0 ,上傳網站 後發現是403錯誤.不能訪問.

經與技術人員聯絡,把虛擬機器更換到高版本.net4.5.1上面,還是不行.在本地IIS環境下可以訪問.遠端伺服器下不能訪問.


多方查資料未能解決.伺服器提供方也無能為力了.只能自己再想辦法解決.原來在剛剛購買空間時上傳了一個.net2.0的程式,能正常執行.而且伺服器上以經安裝了相應.net框架,理論上是應該能使用的.本著解決問題不怕麻煩的精神,用VS2013建立了多個版本的網站基本程式,(如: .net4.0 MVC4, .net4.5 MVC4, .net4.5 Mvc5,.net4.5.1 MVC5)發現在.net4.0 MVC4,能夠訪問,其它的三個都不能訪問.遂對比Web.config檔案.

仔細觀察發現,在
  <appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
    <add key="webpages:Enabled" value="false" />
       <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
  </appSettings>

中間少一條 <add key="PreserveLoginUrl" value="true" /> 這個應該是登入引導用的.應該用處不大.

最主要的是在  <system.webServer>   </system.webServer>  看了網上好多方法,都是在這裡面加上<modules runAllManagedModulesForAllRequests="true" />   ,這個我試了,不管用,反而會引發500錯誤.經過對比,發現需要加入以下程式碼

  <system.webServer>
 
    <validation validateIntegratedModeConfiguration="false" />
    
    <modules runAllManagedModulesForAllRequests="true" />
    
  <handlers>
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>

  </system.webServer>

當然了,你的配置節裡有其它配置,就要自己有選擇的添加了.

經測試,成功!!!!現記錄下來,一來備忘,二來可以幫助有需要的人.
