【问题标题】:Routing not working in Symfony 3.4路由在 Symfony 3.4 中不起作用
【发布时间】:2018-08-18 08:42:41
【问题描述】:

我创建了一个新的 Symfony 3.4 项目,使用:

composer create-project symfony/skeleton my-project

之后我添加了以下组件:

composer require twig
composer require annotations
composer require maker

并创建了一个控制器:

php bin/console make:controller

我添加了一个带有“合法”路线的动作。这是默认控制器:

<?php

namespace App\Controller;

use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class DefaultController extends Controller
{
    /**
     * @Route("/", name="homepage")
     */
    public function index()
    {
        return $this->render('index.html.twig', [
            'controller_name' => 'DefaultController',
        ]);
    }

    /**
     * @Route("/legal", name="legal")
     */
    public function legal()
    {
        return $this->render('legal.html.twig', []);
    }
}

文件配置/routes.yaml:

#index:
#    path: /
#    defaults: { _controller: 'App\Controller\DefaultController::index' }

还有 config/routes/annotations.yaml:

controllers:
    resource: ../../src/Controller/
    type: annotation

当我访问主页时,没问题,页面正在显示。但是当我尝试 /legal 页面时,我有一个 404 :

未找到 - 在此服务器上未找到请求的 URL /legal。

php bin/console debug:router 显示预期:

 ------------------ -------- -------- ------ -------------------------- 
  Name               Method   Scheme   Host   Path                      
 ------------------ -------- -------- ------ -------------------------- 
  homepage           ANY      ANY      ANY    /                         
  legal              ANY      ANY      ANY    /legal                    
  _twig_error_test   ANY      ANY      ANY    /_error/{code}.{_format}  
 ------------------ -------- -------- ------ -------------------------- 

我使用控制台命令清除了缓存,并删除了 var/cache 目录的内容。但仍然是 404。

我是 3.4 的新手。有任何想法吗 ?谢谢...

【问题讨论】:

  • 您是使用内置的 PHP 服务器还是通过 Apache 提供服务?
  • 你的/ 路线有效吗?
  • 如果你使用 Sensio\Bundle\FrameworkExtraBundle\Configuration\Route 而不是 Symfony\Component\Routing\Annotation\Route 会怎样?
  • @jljohnstone:我通过 Apache 为站点提供服务,@Antoine Galluet:是的,/ 路线有效。我发现我忘记了 .htaccess,它不是由 Symfony/Flex 自动创建的(见我的回答)。

标签: symfony symfony-3.4


【解决方案1】:

好吧,正如@Basel Issmail 指出的那样,Symfony/Flex 不像以前的 Symfony 安装程序那样创建 .htaccess,我已经忘记了。

我只有一个最小的 Apache 配置文件:

<VirtualHost *:80>
    DocumentRoot /path/to/my-project/public
    ServerName myproject.localhost

    <Directory /path/to/my-project/public>
        Options -Indexes +FollowSymLinks -MultiViews
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

所以我在/public/index.php 文件所在的位置)中创建了.htaccess 文件,所需的最低配置类似于:

<IfModule mod_rewrite.c>
    RewriteEngine On

    # Determine the RewriteBase automatically and set it as environment variable.
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]

    # If the requested filename exists, simply serve it.
    # We only want to let Apache serve files and not directories.
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule .? - [L]

    # Rewrite all other queries to the front controller.
    RewriteRule .? %{ENV:BASE}/index.php [L]
</IfModule>

缺少的部分是将所有查询(除了资产等现有文件)重写为index.php,以便 Symfony 处理路由。

--- 编辑---

您也可以使用 symfony flex 配方,而不是手动创建 .htaccess:

composer require apache-pack

这将安装this .htacess file

【讨论】:

    【解决方案2】:

    听起来你需要用 apache 设置你的 RewriteBase,因为问题不在 /

    可能 .htaccess 文件甚至丢失了,因为您使用的是 Symfony/flex,并且它不会像以前的 Symfony 版本那样默认添加它。

    查看此页面至configure a Web Server

    .htaccess 应该在公共文件夹中,并且让您的应用程序在 Apache 下运行的最低配置是:

    <VirtualHost *:80>
        ServerName domain.tld
        ServerAlias www.domain.tld
    
        DocumentRoot /var/www/project/public
        <Directory /var/www/project/public>
            AllowOverride All
            Order Allow,Deny
            Allow from All
        </Directory>
    
        # uncomment the following lines if you install assets as symlinks
        # or run into problems when compiling LESS/Sass/CoffeeScript assets
        # <Directory /var/www/project>
        #     Options FollowSymlinks
        # </Directory>
    
        ErrorLog /var/log/apache2/project_error.log
        CustomLog /var/log/apache2/project_access.log combined
    </VirtualHost>
    

    【讨论】:

    • 感谢您的回答,它为我指明了正确的方向;我忘记了.htaccess。但重要的部分是重写规则将所有请求重定向到index.php,所以我写了一个完整的答案。
    【解决方案3】:

    您是否在 AppKernel.php 中加载了 Bundle “App”? 有一个数组,您必须在其中打开添加您的 Bundle 的 AppBundle.php。

    $bundles = [
    /**lot of other bundles*//
    new App\AppBundle() 
    ]
    

    一定是这样的

    【讨论】:

    • 谢谢,但在我的情况下没有必要,因为我还没有创建 AppBundle(所有源代码都直接在 /src/ 目录下)。
    【解决方案4】:

    在 Synology DSM 6.2 上安装 symfony 时遇到同样的问题。 我确认,只需运行 scandel 提到的“composer require apache-pack”,注释路由就可以很好地工作。带有 rewrite cond 的 .htaccess 文件将在“public”文件夹中自动创建。

    谢谢! :)

    这里是 symfony flex 安装创建的 .htaccess 文件:

    #----------------------------
    # Use the front controller as index file. It serves as a fallback solution when
    # every other rewrite/redirect fails (e.g. in an aliased environment without
    # mod_rewrite). Additionally, this reduces the matching process for the
    # start page (path "/") because otherwise Apache will apply the rewriting rules
    # to each configured DirectoryIndex file (e.g. index.php, index.html, index.pl).
    DirectoryIndex index.php
    
    # By default, Apache does not evaluate symbolic links if you did not enable this
    # feature in your server configuration. Uncomment the following line if you
    # install assets as symlinks or if you experience problems related to symlinks
    # when compiling LESS/Sass/CoffeScript assets.
    # Options FollowSymlinks
    
    # Disabling MultiViews prevents unwanted negotiation, e.g. "/index" should not resolve
    # to the front controller "/index.php" but be rewritten to "/index.php/index".
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>
    
    <IfModule mod_rewrite.c>
        RewriteEngine On
    
        # Determine the RewriteBase automatically and set it as environment variable.
        # If you are using Apache aliases to do mass virtual hosting or installed the
        # project in a subdirectory, the base path will be prepended to allow proper
        # resolution of the index.php file and to redirect to the correct URI. It will
        # work in environments without path prefix as well, providing a safe, one-size
        # fits all solution. But as you do not need it in this case, you can comment
        # the following 2 lines to eliminate the overhead.
        RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
        RewriteRule ^(.*) - [E=BASE:%1]
    
        # Sets the HTTP_AUTHORIZATION header removed by Apache
        RewriteCond %{HTTP:Authorization} .
        RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    
        # Redirect to URI without front controller to prevent duplicate content
        # (with and without `/index.php`). Only do this redirect on the initial
        # rewrite by Apache and not on subsequent cycles. Otherwise we would get an
        # endless redirect loop (request -> rewrite to front controller ->
        # redirect -> request -> ...).
        # So in case you get a "too many redirects" error or you always get redirected
        # to the start page because your Apache does not expose the REDIRECT_STATUS
        # environment variable, you have 2 choices:
        # - disable this feature by commenting the following 2 lines or
        # - use Apache >= 2.3.9 and replace all L flags by END flags and remove the
        #   following RewriteCond (best solution)
        RewriteCond %{ENV:REDIRECT_STATUS} ^$
        RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]
    
        # If the requested filename exists, simply serve it.
        # We only want to let Apache serve files and not directories.
        RewriteCond %{REQUEST_FILENAME} -f
        RewriteRule ^ - [L]
    
        # Rewrite all other queries to the front controller.
        RewriteRule ^ %{ENV:BASE}/index.php [L]
    </IfModule>
    
    <IfModule !mod_rewrite.c>
        <IfModule mod_alias.c>
            # When mod_rewrite is not available, we instruct a temporary redirect of
            # the start page to the front controller explicitly so that the website
            # and the generated links can still be used.
            RedirectMatch 307 ^/$ /index.php/
            # RedirectTemp cannot be used instead
        </IfModule>
    </IfModule>
    #----------------------------
