显示危险请求的友好错误页面

Question

我的ASP .Net网站的web.config配置为

  <system.web>
   .....
    <customErrors mode="RemoteOnly">
      <error statusCode="500" redirect="/500/" />
    </customErrors>

  <system.webServer>
    ....
    <httpErrors>
      <remove statusCode="400" subStatusCode="-1" />
      <remove statusCode="401" subStatusCode="-1" />
      <remove statusCode="403" subStatusCode="-1" />
      <remove statusCode="404" subStatusCode="-1" />
      <remove statusCode="500" subStatusCode="-1" />
      <error statusCode="400" path="/404/" responseMode="Redirect" />
      <error statusCode="401" path="/404/" responseMode="Redirect" />
      <error statusCode="403" path="/404/" responseMode="ExecuteURL" />
      <error statusCode="404" path="/404/" responseMode="ExecuteURL" />
      <error statusCode="500" path="/500/" responseMode="ExecuteURL" />
    </httpErrors>

我测试了一个404页面，并显示了我的友好错误页面，但是当我在URL上添加

我错过了什么？

Answer 1

在URL中添加“

<customErrors mode="On" defaultRedirect="/MyError1.html" redirectMode="ResponseRedirect">
    <error statusCode="400" redirect="/MyError400.html" />
    <!--<error statusCode="401" redirect="/MyError2.html" />
    <error statusCode="403" redirect="/MyError2.html" />
    <error statusCode="404" redirect="/MyError2.html" />
    <error statusCode="500" redirect="/MyError2.html" />-->
  </customErrors>

[就我而言，我通常将custom error功能与http error功能结合使用以处理错误，因为IIS和DotNet代码都可能引发异常。它还可以避免YSOD。 
<customErrors mode="On" defaultRedirect="/MyError1.html" redirectMode="ResponseRedirect">
    <error statusCode="400" redirect="/MyError400.html" />
    <!--<error statusCode="401" redirect="/MyError2.html" />
    <error statusCode="403" redirect="/MyError2.html" />
    <error statusCode="404" redirect="/MyError2.html" />
    <error statusCode="500" redirect="/MyError2.html" />-->
  </customErrors>
  </system.web>
  <system.webServer>
    <httpErrors errorMode="Custom" existingResponse="Auto">
      <remove statusCode="400" />
      <remove statusCode="401" />
      <remove statusCode="403" />
      <remove statusCode="404" />
      <remove statusCode="500" />
      <error statusCode="400" path="MyError.html" responseMode="File" />
      <error statusCode="401" path="MyError.html" responseMode="File" />
      <error statusCode="403" path="MyError.html" responseMode="File" />
      <error statusCode="404" path="MyError.html" responseMode="File" />
      <error statusCode="500" path="MyError.html" responseMode="File" />
    </httpErrors>
  </system.webServer>

结果。更多细节。What is the difference between customErrors and httpErrors?请随时告诉我是否有什么我可以帮助的。
