在Laravel 5刀片模板中包含SVG文件（位于assets文件夹中）的内容的最佳方法是什么？
我不想使用image / object / embed标签，出于速度原因，这应该是内联SVG。
我知道我可以使用<?php file_get_contents("file.svg") ?>但是有更好的方法专门针对Laravel / Blade吗？
编辑：为了澄清，该方法应该与所有 SVG文件一起使用，包括下面的文件。
<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg">
<path stroke="red" fill="#00f" d="M10 10h100v100H10z"/>
</svg>

与接受的答案类似，但有点清洁（imo）。
使用laravel指令扩展刀片，就像这样（在您的App Service Provider中，按照here概述）：
\Blade::directive('svg', function($arguments) {
// Funky madness to accept multiple arguments into the directive
list($path, $class) = array_pad(explode(',', trim($arguments, "() ")), 2, '');
$path = trim($path, "' ");
$class = trim($class, "' ");
// Create the dom document as per the other answers
$svg = new \DOMDocument();
$svg->load(public_path($path));
$svg->documentElement->setAttribute("class", $class);
$output = $svg->saveXML($svg->documentElement);
return $output;
});
然后在你的刀片中使用它：
<div class="Login__image Login__cloud">
@svg('cloud.svg', 'Cloud')
</div>

这是有效的，这是我能想到的最简单的方法：

答案 2 :(得分：9)
为什么不将svg放入刀片模板？
resources/views/icons/dashboard.blade.php
然后使用刀片语法添加您的视图？
@include('icons.dashboard')
答案 3 :(得分：5)
我最终在服务提供商中使用了一个视图编辑器。
在服务提供商的boot()方法中：
// Wildcard view composer
view()->composer('*', function($view) {
// Instantiate new DOMDocument object
$svg = new DOMDocument();
// Load SVG file from public folder
$svg->load(public_path('images/logo.svg'));
// Add CSS class (you can omit this line)
$svg->documentElement->setAttribute("class", "logo");
// Get XML without version element
$logo = $svg->saveXML($svg->documentElement);
// Attach data to view
$view->with('logo', $logo);
});
在我看来：
<!-- Echo unescaped SVG content -->
{!! $logo !!}
我正在使用DOMDocument因为它允许我删除不应该在HTML中的XML版本元素。
CSS类不是必需的，但可以节省我用另一个HTML元素包装徽标以进行样式化。
如果您只需要特定刀片部分中的徽标，例如标题，您可以写
view()->composer('header', function($view) {});
http://laravel.com/docs/5.0/views#view-composers
https://laracasts.com/series/laravel-5-fundamentals/episodes/25
这种方法不是最佳实践，因为这种代码实际上不应该在视图中。然而，它比在每个视图中添加PHP代码都简单得多。
使用以下代码创建一个新的部分（让我们说logo.blade.php）：
<?php
// Instantiate new DOMDocument object
$svg = new DOMDocument();
// Load SVG file from public folder
$svg->load(public_path('images/logo.svg'));
// Add CSS class (you can omit this line)
$svg->documentElement->setAttribute("class", "logo");
// Echo XML without version element
echo $svg->saveXML($svg->documentElement);
?>
您现在可以在刀片模板中使用SVG图像，方法是将部分包括在内：
@include('logo')
