Symfony 4 routes.yaml路由配置问题求助

Hey there! I totally get that starting out with a new framework like Symfony 4 can throw you for a loop when things don’t work as expected—let’s break down how to fix your routing problem.

First, to help diagnose exactly what’s going wrong, could you share a few more details?

• The full error message you see when running php bin/console debug:router (copy-paste it if you can—even a snippet will help spot syntax issues or missing references).
• The complete content of your routes.yaml file (YAML is super picky about indentation and syntax, so a small typo here can break everything).
• A quick check that your hello_page.html.twig is definitely in the templates/ directory (double-check spelling and capitalization—even small mistakes like Hello_Page.html.twig instead of hello_page.html.twig can cause issues, especially on case-sensitive systems).

In the meantime, here are some common pitfalls to double-check:

• YAML Indentation: Make sure you’re using spaces (not tabs) for indentation, and each level is consistently indented. For example, a valid template-rendering route looks like this:

  hello_page:
      path: /hello
      controller: 'framework:template:template'
      defaults:
          template: 'hello_page.html.twig'
  

• Controller Syntax: If you’re using a custom controller instead of rendering a template directly, ensure the controller reference follows the App\Controller\YourController::methodName format.
• Command Context: Confirm you’re running the php bin/console debug:router command from your project’s root directory (C:\xampp\htdocs\my_project)—running it from the wrong folder will lead to errors too.

Once you share those extra details, we can narrow down the exact issue and get your routing working!
