Symfony profiler throws 404
提问by Mati
I've created new project in symfony and I get an error prompt on each site:
我在 symfony 中创建了新项目，并且在每个站点上都收到错误提示：
An error occurred while loading the web debug toolbar (404: Not Found).
Do you want to open the profiler?
加载 Web 调试工具栏时出错（404：未找到）。
您要打开分析器吗？
When I open the profiler there is a message
当我打开分析器时，有一条消息
Token not found
Token "59942c" was not found in the database.
未找到
令牌 在数据库中未找到令牌“59942c”。
Moreover, in the cache directory the profiler directory is empty! I checked permissions and they're proper. I tried cache:clearand removing cache manually, but that didn't help.
此外，在缓存目录中，分析器目录是空的！我检查了权限，它们是正确的。我尝试cache:clear手动删除缓存，但这没有帮助。

It's often problem with event subscriber/listener. Try run
事件订阅者/侦听器通常有问题。尝试运行
console debug:event
And check for errors
并检查错误

This usually happens if the cache directory is not properly set up to allow the web servers' user to write data into them.
如果未正确设置缓存目录以允许 Web 服务器的用户将数据写入其中，则通常会发生这种情况。
Under Linux, I would usually use this for development:
在 Linux 下，我通常会使用它进行开发：
php app/console --env=dev cache:clear
php app/console --env=dev cache:warmup
chmod -R a+rwX app/cache/
setfacl -Rm g:www-data:rwX app/cache/
setfacl -Rm g:dev-user:rwX app/cache/
This ensures all required directories will be created and then assigned the required permissions. If you do not have ACL enabled, skip the setfaclcommands.
这确保将创建所有必需的目录，然后分配所需的权限。如果您没有启用 ACL，请跳过这些setfacl命令。
OFC, replace www-datawith your web servers' username, and dev-userwith your username.
OFC，替换www-data为您的 Web 服务器的用户名和dev-user您的用户名。

This is a known bugin the profiler. Since Symfony 2.4, the profiler persisting the data used by the WDT is the very last thing done by Symfony.
这是分析器中的一个已知错误。从 Symfony 2.4 开始，保存 WDT 使用的数据的分析器是 Symfony 所做的最后一件事。
The alert you see means that the profiler has not been able to find the token requested in the 2500ms allowed, However if you click OK in the alert, you should be redirected to the profiler and figure out what precisely is slow.
您看到的警报意味着探查器在允许的 2500 毫秒内无法找到请求的令牌，但是如果您在警报中单击“确定”，您应该被重定向到探查器并找出究竟是什么缓慢。

I had the same issue after upgrading Symfony 2.3->2.6. After upgrading web/app_dev.phpit fixed the issue. I believe you need the Debug::enable();line.
升级 Symfony 2.3->2.6 后我遇到了同样的问题。升级后web/app_dev.php问题解决。我相信你需要这Debug::enable();条线。

Had the same issue after upgrading 2.6 -> 2.8 on a 2.4 era project. Got a useMicrosecondTimestampserror with the node layer. Fixed by nuking rm -r app/cache/*. @marenkay's method did not clear the node-php server cache.
在 2.4 时代的项目上升级 2.6 -> 2.8 后遇到了同样的问题。得到了useMicrosecondTimestamps与节点层错误。通过 nuking 修复rm -r app/cache/*。@marenkay 的方法没有清除 node-php 服务器缓存。

Try to edit or add your htacces file like this

# 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(?:/(.*)|$) %{ENV:BASE}/ [R=301,L]
# If the requested filename exists, simply serve it.
# We only want to let Apache serve files and not directories.
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
# Rewrite all other queries to the front controller.
RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>
<IfModule !mod_rewrite.c>
<IfModule mod_alias.c>
# When mod_rewrite is not available, we instruct a temporary redirect of
# the start page to the front controller explicitly so that the website
# and the generated links can still be used.
RedirectMatch 307 ^/$ /index.php/
# RedirectTemp cannot be used instead
</IfModule>
