如何在 Asp.net MVC 3 站点中保护 Elmah（将使用 IIS 7.5 - 现在在本地主机上）

Question

我正在尝试在 asp.net mvc 3 应用程序中保护 elmah。

我一直在寻找，发现这是这样做的方法

<location path="elmah.axd">
    <system.web>
        <authorization>
            <allow roles="Admin" />
            <deny users="*" />
        </authorization>
    </system.web>
</location>

然而，当我这样做时，resharper 说“位置元素未使用，在 elmah.axd 找不到项目项目”

当我用 system.web 周围的位置加载我的网站时，我得到

Server Error in '/' Application.
There is no build provider registered for the extension '.cshtml'. You can register one in the <compilation><buildProviders> section in machine.config or web.config. Make sure is has a BuildProviderAppliesToAttribute attribute which includes the value 'Web' or 'All'.

因此它基本上失去了渲染剃刀视图的能力。

我运气不错

<location path="admin">
    <system.web>
      <httpHandlers>
        <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
      </httpHandlers>
      <authorization>
        <allow users="bzink" />
        <deny users="*" />
      </authorization>
    </system.web>
  </location>

我现在可以从http://host/admin/elmah.axd 访问 elmah 页面。

OHHHH 只是更仔细地重新阅读您的问题。你说...“当我用 system.web 周围的位置加载我的网站时

那是你的问题。您需要保持 system.web 完整。这是结构的外观。

做所有重要的事情，比如缓存、授权、http 处理程序等。你不需要接触这个部分。

</system.web>
<system.diagnostics>diagnostics was next, but i don't think that should matter</system.diagnostics>
<location path="admin">
        <system.web>
          <httpHandlers>
            <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
          </httpHandlers>
          <authorization>
            <allow users="bzink" />
            <deny users="*" />
          </authorization>
        </system.web>
      </location>

看到您需要主 system.web，然后在每个位置标签中添加一个额外的 system.web。

我正在使用 MVC 4，我搜索并尝试了一些东西，终于成功了。

<appSettings>
<add key="elmah.mvc.requiresAuthentication" value="true" />
...
</appSettings>

将值更改为“真”。这将打开您的登录页面，您还可以设置角色等。至少，这将需要身份验证。
