php - 使用 rest api 获取 json 或 XML 格式的 joomla 文章

Question

我有一个移动应用程序(实际上是 Cordova HTML 移动应用程序)和一个客户 Web 应用程序 (php) 以及一个主要的基于 joomla 的网站。 这个 jooma 网站是我系统的基础，我想在移动应用程序(使用 JavaScript)和我的网络应用程序中显示它的博客文章。

我可以使用 RSS 提要来显示标题，但它是有限的(某种程度上)。我知道 php 和一些关于为 joomla 创建简单组件/模块的知识。知道我认为如何以正确的方式从 dB 获取文章吗？

博客文章是公开的，我需要知道我必须如何从数据库中获取文章，或者是否有任何扩展？

我还需要按点击率和发布日期来订购文章。

Answer 1

我为我自己的 joomla 网站创建了一种类似的脚本，我在其中获取 2 个日期范围之间的文章。

我的解决方法是在 joomla 之外的自定义 php 文件中初始化 joomla 框架，该文件位于 joomla 文件夹的根目录中。

我将我的文件命名为 articleApi.php 并保存在 joomla 的根目录下(假设您的 joomla 是 3.5.x 或更高版本)

这是我的脚本:

我使用纪元时间戳来获取 2 个日期之间的文章，url 应该是:http://YOUR_JOOMLA_SITE.COM/articleApi.php?starttime=1503260194&endtime=1503519394
