The profiler toolbar needs <body> ... </body>. I guess you don't have it in your twig file(s).

Profiler

# app/config/config_dev.yml
web_profiler:
    toolbar: true
    intercept_redirects: false

Example twig file.

The line {% extends '::base.html.twig' %} will extend app/Resources/views/base.html.twig which injects default <body>...</body> into your custom twig files.

{% extends '::base.html.twig' %}

{% block body %}
   Hello!
{% endblock %}

回答2:

In case your action not returning html code (e.g json API) and you want to use profiler:

Quick and dirty solution:

return new Response("<html><body>Debug data</body></html>");

Even quicker and dirtier solution - returning non Response type in controller will raise exception with profiler enabled response:

return 1;

If your application is running by Symfony >=2.4 you can also use X-Debug-Token which contains debug token and X-Debug-Token-Link header which contains link to profiler page. If you want to use this method Chrome extension Symfony2 Profiler shortcut will increase your user experience.

回答3:

have you enabled it in the config.yml or parameters.yml file? Are you in dev mode ? calling app_dev.php ?

also, it sometimes is minismised to a tidy square in the bottom right of the browser.

just some ideas that may help

回答4:

Like the answer above has indicated, the web profiler doesn't appear in simple twig files that have a tag etc.

{% extends 'base.html.twig' %}

{% block body %}
    Hello {{name}}.
{% endblock %}

shows the web profiler, but something simple like:

 <body>
    Hello {{name}}.
 </body>

would work, but not show the web profiler.

回答5:

I had the same issue.

The problem was in my routes definition. I has something like this:

load_home:
    path: /{page}
    defaults: {_controller: ExpatsBundle:Pages/Home:index, _format: html|json, page: 1}
    methods: GET
    requirements:
        page: \d+

So changing the _format: html|json to _format: html has solved the problem.
