IIS7 + WCF + Silverlight問題

Question

我一直在構建Silverlight應用程序和WCF服務一段時間，最近試圖在IIS7中託管它們。

我在Windows Server 2008 R2上安裝了IIS7，並將這兩個應用程序添加到我的默認網站。我有一些問題，所以我希望你們中的一個人可以幫忙...

1）Silverlight和WCF服務應用程序不能使用傳遞身份驗證。在設置應用程序時，我需要「連接成」管理員服務器帳戶。我在網上閱讀時，您應該只需要在連接到另一臺計算機時使用「connect as」字段。如果我不提供管理員憑據，我得到這個錯誤。我必須在其他地方設置權限嗎？

HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Detailed Error Information Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x80070005 Config Error Cannot read configuration file due to insufficient permissions Config File \?\C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\WCFService\Website\web.config Requested URL http:://localhost:80/WCFService/Service.svc Physical Path C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\WCFService\Website\Service.svc Logon Method Not yet determined Logon User Not yet determined Config Source -1: 0: Links and More Information This error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error.

2）Visual Studio生成2個網頁來運行我的Silverlight應用程序（.html和.aspx）。當我運行Silverlight應用程序（以管理員身份連接）時，我可以導航到.html頁面，沒問題。當我嘗試打開.aspx文件我得到以下錯誤

Server Error in '/Platform' Application.

Access is denied.

Description: An error occurred while accessing the resources required to serve this request. You might not have permission to view the requested resources.

Error message 401.3: You do not have permission to view this directory or page using the credentials you supplied (access denied due to Access Control Lists). Ask the Web server's administrator to give you access to 'C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\Platform\Website\PlatformTestPage.aspx'.

Version Information: Microsoft .NET Framework Version:4.0.30128; ASP.NET Version:4.0.30128.1

3）WCF服務運行正常（同樣，作爲連接管理），直到我重新啓動服務器。當我嘗試在重新啓動後運行WCF服務時，似乎從解決方案中缺少了mysql程序集。如果我只是重建解決方案並再次運行該服務......它的工作原理（直到下一次重新啓動）。什麼導致這個錯誤？這裏

僅此而已，希望有人讀這條消息，我浪費了大部分的週末試圖解決我自己這些問題...感謝

你切不可能夠使用IIS7託管silverlight應用程序。 嘗試使用php/html腳本在apache服務器上託管您的silverlight應用程序。

我的建議：

1）檢查你的web應用程序文件夾的權限。您應該編輯Web應用程序文件夾的權限，以便IIS用戶可以從該文件夾讀取。 因此，您應該在Windows資源管理器中打開文件夾的文件夾屬性對話框，並檢查應用程序池用戶是否至少具有讀取權限。如果您沒有爲應用程序池提供其他用戶，則默認用戶應爲IIS_IUSRS。

2）檢查asp.net通過運行在你的系統中啓用：

如果您有.NET 4.0安裝在系統： 「％WINDIR％\ Microsoft.NET \框架\ v4.0.30319 \ ASPNET_REGIIS.EXE」 -i 否則： 「％WINDIR％\ Microsoft.NET \框架\ V2.0.50727 \ ASPNET_REGIIS.EXE」 -i

上面的命令將註冊/修復您的.NET安裝與IIS。

3）您的mysql dll是否位於bin文件夾中？我會檢查你是否也有權限閱讀這個文件夾。如果該dll與您的應用程序dll不在同一個文件夾中，請檢查該dll是否安裝在GAC中。

Regards，

1）授予IIS_IUSRS組文件夾的權限。 另請參閱IIS管理器 - >「應用程序池」中的應用程序的應用程序池是否將Identity設置爲「LocalSystem」。對我而言，它是「NetworkService」，將其設置爲「LocalSystem」解決了它。
