路由在 Symfony 3.4 中不起作用
Routing not working in Symfony 3.4
我使用以下方法创建了一个新的 Symfony 3.4 项目：
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
我添加了一个带有路由 "legal" 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config/routes.yaml:
#index:
# path: /
# defaults: { _controller: 'App\Controller\DefaultController::index' }
和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 :
Not Found - The requested URL /legal was not found on this server.
php bin/console debug:router 显示预期的：
------------------ -------- -------- ------ --------------------------
Name Method Scheme Host Path
------------------ -------- -------- ------ --------------------------
homepage ANY ANY ANY /
legal ANY ANY ANY /legal
_twig_error_test ANY ANY ANY /_error/{code}.{_format}
------------------ -------- -------- ------ --------------------------
我清除了缓存，使用控制台命令并删除了 var/cache 目录的内容。但是还是404。
我是 3.4 的新手。有任何想法吗 ？谢谢...
您是否在 AppKernel.php 中加载了 Bundle "App"？
有一个数组，您必须在其中打开并添加 Bundle 的 AppBundle.php。
$bundles = [
/**lot of other bundles*//
new App\AppBundle()
]
它必须看起来像这样
听起来你需要用 apache 设置你的 RewriteBase，因为问题不在 /
也许 .htaccess 文件甚至丢失，因为您正在使用 Symfony/flex，并且它不会像以前的 Symfony 版本那样默认添加它。
检查此页面以 configure a Web Server
.htaccess 应该在 public 文件夹内并且在 Apache 下获取应用程序 运行 的最低配置是：
<VirtualHost *:80>
ServerName domain.tld
ServerAlias www.domain.tld
DocumentRoot /var/www/project/public
<Directory /var/www/project/public>
AllowOverride All
Order Allow,Deny
Allow from All
</Directory>
# uncomment the following lines if you install assets as symlinks
# or run into problems when compiling LESS/Sass/CoffeeScript assets
# <Directory /var/www/project>
# Options FollowSymlinks
# </Directory>
ErrorLog /var/log/apache2/project_error.log
CustomLog /var/log/apache2/project_access.log combined
</VirtualHost>
好吧，正如@Basel Issmail 指出的那样，Symfony/Flex 不会像以前的 Symfony 安装程序那样创建 .htaccess，我忘记了它。
我只有一个最小的 Apache 配置文件：
<VirtualHost *:80>
DocumentRoot /path/to/my-project/public
ServerName myproject.localhost
<Directory /path/to/my-project/public>
Options -Indexes +FollowSymLinks -MultiViews
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
所以我在 /public/ 中创建了 .htaccess 文件（index.php 文件所在的位置），所需的最低配置如下：
<IfModule mod_rewrite.c>
RewriteEngine On
# Determine the RewriteBase automatically and set it as environment variable.
RewriteCond %{REQUEST_URI}:: ^(/.+)/(.*)::$
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（资产等现有文件除外）重写为 index.php，以便 Symfony 处理路由。
---编辑---
除了手动创建 .htaccess，您还可以只使用 symfony flex 配方：
composer require apache-pack
这将安装 this .htacess file。
在 Synology DSM 6.2 上安装 symfony 时遇到同样的问题。
我确认，就像 scandel 提到的 运行 "composer require apache-pack" 一样，注释路由会很好用。具有重写条件的 .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}:: ^(/.+)/(.*)::$
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}/ [R=301,L]
# If the requested filename exists, simply serve it.
# We only want to let Apache serve files and not directories.

<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/
