Symfony 的 Imgix Bundle

安装

composer require sparwelt/imgix-bundle

基本配置

sparwelt_imgix:
  cdn_configurations:
    my_cdn:
        cdn_domains: ['my.imgix.net']
        sign_key: '12345'

  image_filters:
    my_basic_filter:
        src: {w: 30, h: 60}

基本用法

{# url generation #}
{{ imgix_url('/dir/test.png', {w: 100, h: 200}) }}
{# "https://my.imgix.net/dir/test.png?w=100&h=200" #}

{# image generation #}
{{ imgix_image('/dir/test.png', {src: {w: 100, h: 200}}) }};
{# <img src="https://my.imgix.net/dir/test.png?w=100&h=200"> #}

{# html conversion #}
{{ imgix_html('<li><img src="/test.png"><\li><li><img src="/test2.png">', {src: {w: 100, h:  200}}) }}
{# <li><img src="https://my.imgix.net/test.png?h=200&w=100"><\li><li><img src="https://my.imgix.net/test2.png?h=200&w=100"> #}

响应式用法

{# image generation #}
{{ imgix_image('/dir/test.png', {
            src: {h: 150, w: 300},
            srcset: {
                100w: {h: 300, w: 600},
                500w: {h: 600, w: 900},
            },
            sizes: '(min-width: 900px) 1000px, (max-width: 900px)'
}) }}
{# <img src="https://test.imgix.net/dir/test.png?h=150&w=300"
        srcset="https://test.imgix.net/dir/test.png?h=300&w=600 100w, https://test.imgix.net/dir/test.png?h=600&w=900 500w"
        sizes="(min-width: 900px) 1000px, (max-width: 900px)"> #}

{# image generation #}
  <img srcset="{{imgix_attr('test.png', {
    '2x': {w: 400, h: 200}
    '3x': {w: 600, h: 300}
  }) }}">

{# <img srcset="https://test.imgix.net/test.png?h=200&w=400 2x, https://test.imgix.net/test.png?h=300&w=600 3x"> #}

懒加载

{{ imgix_image('/dir/test.png', {
    'src': {h: 30, w: 60},
    'srcset': 'data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==',
    'data-srcset': {
        '100w': {'h': 60, 'w': 120}
        '500w': {'h': 90, 'w': 180},
    },
    'data-sizes': 'auto',
    'class': 'lazyload',
}) }}
{# <img src="https://test.imgix.net/dir/test.png?h=30&w=60" 
       srcset="data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw=="
       data-srcset="https://test.imgix.net/dir/test.png?h=60&w=120 100w, https://test.imgix.net/dir/test.png?h=90&w=180 500w"
       data-sizes="auto" 
       class="lazyload">
#}

命名过滤器

为了避免每次使用都重复过滤器，可以一次性配置命名过滤器，并按名称调用

sparwelt_imgix:
  image_filters:
    my_basic_filter:
        src: {w: 30, h: 60}
    my_blur_lazyload_filter:
        src: {w: 30, h: 60}
        data-src: {h: 30, w: 60, blur: 1000}
        data-srcset:
            100w: {h: 60, w: 120}
            500w: {h: 90, w: 180}
        data-sizes: 'auto'
        class: 'lazyload'

{{ imgix_image('dir/test.png', 'my_basic_filter') }}
{# <img src="https://test.imgix.net/dir/test.png?h=30&w=60"> #}

{{ imgix_image('dir/test.png', 'my_blur_lazyload_filter') }}
{# <img src="https://test.imgix.net/dir/test.png?h=30&w=60" 
       data-src="https://test.imgix.net/dir/test.png?blur=1000h=30&w=60"
       data-srcset="https://test.imgix.net/dir/test.png?h=60&w=120 100w, https://test.imgix.net/dir/test.png?h=90&w=180 500w"
       data-sizes="auto" 
       class="lazyload">
#}

{{ imgix_url('dir/test.png', 'my_basic_filter.src') }}
{# https://test.imgix.net/test.png?h=30&w=60 #}

{{ imgix_url('dir/test.png', 'my_basic_filter.src', {q: 75}) }}
{# https://test.imgix.net/test.png?h=30&w=60&q=75 #}

{{ imgix_attr('dir/test.png', 'my_blur_lazyload_filter.data-srcset') }}
{# https://test.imgix.net/dir/test.png?h=60&w=120 100w, https://test.imgix.net/dir/test.png?h=90&w=180 500w #}

{{ imgix_html($html, 'my_blur_lazyload_filter') }}
{# ... replaces all images with responsive ones #}

多个 CDN 配置

图像路径将按照从上到下的顺序与配置进行评估，直到找到合适的匹配项。可以为同一配置指定多个域名（域名分片）。

sparwelt_imgix:
  cdn_configurations:
        # matches images with source domain 'mysite.com' (including subdomains)
        # AND path beginning with 'uploads/' OR 'media/'

            cdn_domains: ['my-cdn-1.imgix.net']

            path_patterns: ['^[/]shard-crc/']
            shard_strategy: 'crc' #default

        # matches relative urls only, where path begins with 'shard-cycle/'.
        # Will rotate between the 2 cdn domains (increase costs)
        shard_cycle:
