Symfony4：找不到“GET /lucky/number”的路由
[英]Symfony4: No route found for "GET /lucky/number"
问题描述
I am starting to play with symfony4.
我开始玩 symfony4。 I've just created new application and create new LuckyController.我刚刚创建了新的应用程序并创建了新的 LuckyController。 It works with routes.yaml configured in this manner:它与以这种方式配置的 routes.yaml 一起使用：
lucky:
path: /lucky/number
controller: App\Controller\LuckyController::number
With the following controller:使用以下控制器：
<?php
namespace App\Controller;
use Symfony\Component\HttpFoundation\Response;
class LuckyController
{
public function number()
{
return new Response('<html><head></head><body>' . rand(111, 999) . '</body></html>');
}
}
But I want to use annotations.但我想使用注释。 So I decided to comment routes.yaml.所以我决定评论routes.yaml。 Following documentation that explain how to create a route in symfony I've made this:以下文档解释了如何在 symfony 中创建路由，我做了这个：
<?php
namespace App\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
class LuckyController extends Controller
{
/**
* @Route("/lucky/number")
*/
public function number()
{
return new Response('<html><head></head><body>' . rand(111, 999) . '</body></html>');
}
}

有时会出现这个问题，因为php bin/console cache:clear 。你需要运行php bin/console cache:clear 。然后它会正常工作。

In Symfony4 you have to install annotations bundle.在 Symfony4 中，您必须安装annotations包。
Run this command composer require annotations运行此命令composer require annotations
Then restart Your project.然后重新启动您的项目。

I had the same thing when trying the annotations, then I found out with the demo installed (the blog) you need to add the language in the URL.我在尝试注释时遇到了同样的事情，然后我发现安装了演示（博客）后，您需要在 URL 中添加语言。 So the documentation says:所以文档说：
http://localhost:8000/lucky/number will work exactly like before
That did not work.那没有用。 This however did:然而，这确实：
http://localhost:8000/en/lucky/number

As suggested in @Jack70 answer.正如@Jack70 回答中所建议的那样。
https://127.0.0.1:8000/en/random/number https://127.0.0.1:8000/en/random/number
This should work.这应该有效。
If you run the command php bin/console debug:router it would show you the list of routes available as you can see in that list, you need to add the locale (language) as first argument.如果您运行命令php bin/console debug:router它会向您显示可用路由列表，正如您在该列表中看到的那样，您需要添加语言环境（语言）作为第一个参数。
app_annotationsample_number ANY ANY ANY /{_locale}/random/number

If you use annotations - you need check config/routes/anotations.yaml .如果您使用注释 - 您需要检查config/routes/anotations.yaml 。 You need check path to your controller or add new path, for example:您需要检查控制器的路径或添加新路径，例如：
controllers:
resource: ../../src/Controller/
type: annotation

Also, you'll get that error if the route name appears more than once.此外，如果路线名称出现多次，您将收到该错误。
I ran into that error while developing Angular app, so in order to debug I tried that same route in Postman, which I knew used to work fine, but this time it did not throwing the mentioned error.我在开发 Angular 应用程序时遇到了那个错误，所以为了调试，我在 Postman 中尝试了相同的路由，我知道它曾经工作正常，但这次它没有抛出提到的错误。 Luckily, I have just added one new controller, so finding the culprit was easy: the problem was that after copying methods from web controller to api controller I forgot to change route name in one of the methods.幸运的是，我刚刚添加了一个新控制器，因此很容易找到罪魁祸首：问题是在将方法从 web 控制器复制到 api 控制器后，我忘记在其中一种方法中更改路由名称。 So you might wanna be careful when copying :)所以你在复制时可能要小心:)
