86 craft cms之JSon

使用前端框架的web经常会请求服务端的数据并处理，本文介绍如何在template中返回json数据

直接使用twig生成json

{% set products = craft.entries('pages')
[
  {% for page in pages %}
      {
        "title":"{{page.title}}",
        "slug":"{{page.slug}}"
      }
      {% if not loop.last %}
      ,
      {% endif %}
  {% endfor %}
]

使用插件将entities转换为json

setup plug-in
