asp.net 自定义 404 页面 - 不工作

Question

我是一名 php 开发人员，但必须对 asp 站点进行一些更改。我正在尝试将 404 错误重定向到自定义 404 页面。下面是 web.config 页面的代码：

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>

                        <!-- name the rule -->
                        <filteringRule name="user agent deny" scanUrl="false" scanQueryString="false">
                            <scanHeaders>
                            <!-- apply rule to user-agent header -->
                                <add requestHeader="user-agent" />
                            </scanHeaders>
                            <!-- apply rule to all files -->

           <rewrite>
               <rules>
                   <rule name="Redirect to WWW" stopProcessing="true">
                       <match url=".*" />
                       <conditions>
                           <add input="{HTTP_HOST}" pattern="^thetoolstore.ca$" />
                       </conditions>
                       <action type="Redirect" url="http://www.thetoolstore.ca/{R:0}" redirectType="Permanent" />
                   </rule>

                   <rule name="Redirect to root" patternSyntax="Wildcard" stopProcessing="true">
                   <match url="index.asp" />
                       <action type="Redirect" url="/" appendQueryString="false" redirectType="Permanent" />
                   </rule>
                   <rule name="Redirect to HTTPS" stopProcessing="true">
                       <match url="(.*)" />
                       <conditions>
                           <add input="{HTTPS}" pattern="^OFF$" />
                       </conditions>
                       <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" />
                   </rule>
               </rules>
           </rewrite>
    <httpErrors errorMode="Detailed" />


</system.webServer>
<system.net>
    <mailSettings>
        <smtp from="info@thetoolstore.ca">
            <network host="localhost" />
        </smtp>
    </mailSettings>
</system.net>

我尝试添加如下代码：

<httpErrors errorMode="Custom" existingResponse="Replace">
    <remove statusCode="404" subStatusCode="-1" />
    <error statusCode="404" path="404.asp" responseMode="ExecuteURL"/>
</httpErrors>

但这只会给出 500 错误。实际上，我尝试的任何操作都会出现 500 错误。

另外，我很确定这不是 MVC 网站，如果有帮助的话。

谢谢！

Answer 1

它给你一个 500 错误，因为 web.config 文件本身格式错误。它缺少结束标签</configuration>。

还有一个现有的 httpErrors 节点<httpErrors errorMode="Detailed" />。这必须用您的代码（有效）替换。不能有重复。

最后请使用http://www.freeformatter.com/xml-formatter.html 之类的东西来正确格式化该web.config 文件。真是一团糟。
