Question

我在base.html.twig中有这部分代码：

{% stylesheets 'bundles/study/css/*' filter='cssrewrite' %}
    <link rel="stylesheet" href="{{ asset('bundles/study/css/style.css') }}" />
    <link rel="stylesheet" href="{{ asset('bundles/study/css/boilerplate.css') }}">
    <link rel="stylesheet" href="{{ asset('bundles/study/css/jquery-ui.min.css')}}">
    <link rel="stylesheet" href="{{ asset('bundles/study/css/jquery-ui.structure.min.css')}}">
    <link rel="stylesheet" href="{{ asset('bundles/study/css/jquery-ui.theme.min.css')}}">
{% endstylesheets %}

网页代码中的Symfony2 / Twig生成：

<link href="/bundles/study/css/style.css" rel="stylesheet">
<link href="/bundles/study/css/boilerplate.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.structure.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.theme.min.css" rel="stylesheet">
<link href="/bundles/study/css/style.css" rel="stylesheet">
<link href="/bundles/study/css/boilerplate.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.structure.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.theme.min.css" rel="stylesheet">
<link href="/bundles/study/css/style.css" rel="stylesheet">
<link href="/bundles/study/css/boilerplate.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.structure.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.theme.min.css" rel="stylesheet">
<link href="/bundles/study/css/style.css" rel="stylesheet">
<link href="/bundles/study/css/boilerplate.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.structure.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.theme.min.css" rel="stylesheet">
<link href="/bundles/study/css/style.css" rel="stylesheet">
<link href="/bundles/study/css/boilerplate.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.structure.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.theme.min.css" rel="stylesheet">
<link href="/bundles/study/css/style.css" rel="stylesheet">
<link href="/bundles/study/css/boilerplate.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.structure.min.css" rel="stylesheet">
<link href="/bundles/study/css/jquery-ui.theme.min.css" rel="stylesheet">

为什么Twig会对同一个链接产生6次调用？

如果我退出

，我可以提供有关代码的任何信息

＆＃39; {％stylesheets＆＃39; bundles / study / css / *＆＃39;滤波器=＆＃39; cssrewrite＆＃39; ％}＆＃39;和＆＃39; {％endstylesheets％}＆＃39;

所有工作正常（我认为），但我需要理解为什么Twig创建相同行的6倍

Answer 1

键入时：

{% stylesheets 'bundles/study/css/*' filter='cssrewrite' %}

告诉Twig在bundles/study/css中包含所有（*）文件。对于找到的每个文件，您将获得stylesheets和endstylesheets之间的内容，因此基本上，如果您有6个文件，则您将有6次内容...

您应该阅读this article about Symfony2 & Assetic。
