如何创建404错误自定义页面？Sitecore新手求分步指导及资源

Hey there, fellow Sitecore newbie! I’ve walked through this process a few times, so let’s break it down into simple, actionable steps—no confusing jargon, just straightforward instructions.

Step 1: Build Your Custom 404 Content Page #

First, you need an actual page in Sitecore that visitors will see when they hit a 404:

• Open the Content Editor in Sitecore.
• Navigate to your site’s content root (e.g., /sitecore/content/YourSite).
• Right-click, select Insert > Insert from Template, and pick a template that matches your site’s layout (you can use your existing page template or create a simple one just for errors).
• Name the page something like Page-Not-Found or 404-Error.
• Design the page with friendly content: add a "Oops, page not found" message, links back to your homepage, a search bar, or any other helpful elements.
• Publish this page (don’t forget this step—unpublished pages won’t be visible to visitors!).

Step 2: Configure Sitecore’s Error Handling Rules #

Now tell Sitecore to show this page when a 404 occurs:

• Go to the Sitecore Launchpad and open the Control Panel.
• Under the System section, click Error Handling (alternatively, you can navigate directly to /sitecore/system/Settings/Error Handling/Error Pages in the Content Editor).
• Right-click the Error Pages node, select Insert > Error Page.
• In the new error page item:
  • Set the Status Code field to 404.
  • In the Target field, use the content picker to select the Page-Not-Found page you created earlier.
  • If you have a multi-language site, set the Language field to the appropriate language (repeat this step for each language you support).
• Save and publish this error handling configuration.

Step 3: Update web.config to Let Sitecore Handle Errors #

To make sure IIS doesn’t override your custom 404 page, tweak your site’s web.config:

• Open the web.config file in your Sitecore project root.
• Find the <system.webServer> section.
• Look for the <httpErrors> element (if it doesn’t exist, add it).
• Set the existingResponse attribute to "PassThrough" so Sitecore’s custom error page is displayed instead of IIS’s default one:

  <system.webServer>
    <httpErrors existingResponse="PassThrough" />
    <!-- Other settings here -->
  </system.webServer>
  

• Save the web.config file (you may need to restart your Sitecore instance for changes to take effect).

Step 4: Test Your Custom 404 Page #

Time to verify everything works:

• Open your site in a browser and type in a URL that doesn’t exist (e.g., your-site-url.com/nonexistent-page).
• You should see your custom 404 page instead of the generic IIS or Sitecore default error page.
• If you have multi-language support, test with language-specific URLs too (e.g., your-site-url.com/es/nonexistent-page for Spanish).
