Question

我遇到了一个似乎相当常见的问题，但我搜索了类似的问题，但似乎没有更新，所以我希望有人可以在这里提出建议。一旦部署到 Azure 网站上，我就不能让ELMAH在我的mvc4应用程序中工作，而在我的开发环境中本地工作时它可以正常工作。

以下是详细信息：

1）我创建了一个MVC4网络互联网应用程序，并添加了 Elmah.MVC NuGet包（报告页面中显示的Elmah版本为1.2.14706.955）。

2）我通过添加：

完成了对我的web.config的修改（1）

appSettings

：

＆lt; add key =“elmah.mvc.disableHandler”value =“false”/＆gt; ＆lt; add key =“elmah.mvc.disableHandleErrorFilter”value =“false”/＆gt; ＆lt; add key =“elmah.mvc.requiresAuthentication”value =“true”/＆gt; ＆lt; add key =“elmah.mvc.allowedRoles”value =“administrator”/＆gt; ＆lt; add key =“elmah.mvc.route”value =“elmah”/＆gt;

elmah

：

＆lt; security allowRemoteAccess =“true”/＆gt; ＆lt; errorLog type =“Elmah.SqlErrorLog，Elmah”connectionStringName =“DefaultConnection”/＆gt;

我的 DefaultConnection 字符串是一个“标准”SqlServer字符串，如：

<add name="DefaultConnection" connectionString="Server=tcp:servername.database.windows.net,1433;Database=dbname;User ID=username;Password=password;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;" providerName="System.Data.SqlClient" />

现在，在本地处理未处理的异常时会记录到数据库中。在Azure上部署时，会引发异常，但不会将任何内容记录到（Azure SQL）数据库中。

我可以成功地在本地和远程跟踪mywebsite / elmah路由：只有当我尝试远程路由时，elmah生成的视图没有显示任何记录，因为数据库中没有存储任何记录。

同一个远程数据库用于用户帐户和所有其他目的，因此我可以确定Web应用程序可以与数据库通信。简而言之，一旦部署在Azure上，就不会记录任何异常。

我使用以下SQL创建了ELMAH表和存储过程：

CREATE TABLE [dbo].[ELMAH_Error]
(
    [ErrorId]     UNIQUEIDENTIFIER NOT NULL,
    [Application] NVARCHAR(60)  COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,

出于授权原因，发布的脚本不适合sql server azure。
