C# 为错误403.14创建自定义错误目录访问被拒绝

这是我在这里发表的第一篇文章，我在这里和网上的许多其他论坛上搜索了这个问题的解决方案，但没有成功

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

我试图为目录访问拒绝错误403.14创建一个自定义错误，如果有人试图在网站上加载“\u assests”目录。我知道我可以通过在每个目录中添加一个default.aspx页面来解决这个问题，但我想知道是否有一个与web.config文件中的标记类似的站点范围的解决方案

<configuration>
<system.web>
    <customErrors defaultRedirect="/Errors/GenericError.aspx" mode="RemoteOnly">
      <error statusCode="401"
         redirect="/Errors/401.aspx"/>
      <error statusCode="403"
         redirect="/Errors/403.aspx"/>
      <error statusCode="404"
         redirect="/Errors/404.aspx"/>
    <!-- 
      <error statusCode="403.14"
         redirect="/"/>
    -->
    </customErrors>
</system.web>
</configuration>

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

在对web.config进行编码时，我遇到一个错误，即我无法使用带有小数点的状态代码，因为它不是数据类型Int

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

我在服务器2008上有一个IIS 7

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

有什么想法吗？

也许您可以使用基于实际错误代码的重定向方法，使用

Server.GetLastError（）

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

在

Global.asax

中，您将看到如下内容：

protected void Application_Error(object sender, EventArgs e)
{
    if (Context.IsCustomErrorEnabled) {
        ShowCustomErrorPage(Server.GetLastError());
    }
}

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

ShowCustomErrorPage

将有一个switch语句，用于读取HTTP代码并重定向到正确的错误页面

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

更多的是源代码链接，但它可能过于特定于MVC。由于您没有提到您使用MVC，我不想假设并盲目复制粘贴

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

我不太熟悉MVC，但这里的原则看起来可以根据您的场景进行调整

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

资料来源：

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

编辑 找到了两个StackOverflow帖子，这也会有所帮助：

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

如果这听起来很混乱，请提前道歉。很高兴澄清

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

在

web.config

中添加了以下内容，到目前为止似乎还可以使用。不知道为什么，但如果我没有明确告诉403错误重定向到自定义

403.aspx

页面，而不是

genericerro.aspx

页面，我会得到一个500错误。但是，如果我将404错误重定向到我的自定义

404.aspx

页面，则

genericerro.aspx

代码将按预期的方式写入，而且您似乎从未重定向到实际的

404.aspx

页面（请参阅

web.config

的注释部分）。奇怪

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

代码：

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>

<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>

否，不使用MVC。只有asp.net Web表单。

<system.webServer>
    <httpErrors existingResponse="Replace" errorMode="Custom">
        <remove statusCode="403"/>
        <remove statusCode="404"/>
        <error statusCode="403" path="/Errors/403.aspx" responseMode="Redirect"  />
<!-- <error statusCode="403" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<!-- <error statusCode="404" path="/Errors/GenericError.aspx" responseMode="Redirect"  /> -->
<error statusCode="404" path="/Errors/404.aspx" responseMode="Redirect"  />
    </httpErrors>
</system.webServer>
