使用XML-RPC阅读Wordpress博客

标签: android wordpress api rest xml-rpc

无论我在哪里,我都找不到将我的应用程序完全连接到Wordpress的方法。我想做的是:当你没有登录时显示最近的文章(当然是已发布的)和较旧的文章,并为那些用户撰写评论提供便利。

看起来我必须从RSS中提取博客文章(但是下面的文字“阅读更多...”?),然后使用XML-RPC *来评论这些文章。是这样的,还是有人有更好的解决方案? (* metaWeblog.getRecentPosts并不总是在WP上可用)

虽然我可以要求所有者安装一些插件,但我对相关博客的实施没有太多要说的。例如WP-RESTful

请指出正确的方向,因为我花了几天时间寻找一个简单的解决方案,但似乎并不是那样。谢谢!

WordPress移动团队拥有他们使用的XML-RPC解析器的存储库。它的实现和使用相当简单。它由XMLRPCDecodeXMLRPCEncoder组成。

WordPress中的

XML-RPC用于发布。获取帖子的功能非常有限,因为WordPress实现在wp_get_recent_posts()方法中使用wp.getPosts。我在wp_getPosts中采用class-wp-xmlrpc-server.php方法并将wp_get_recent_posts替换为get_posts,从而使功能更加出色。所以我可以使用Wp_Query类中的所有参数。

然后使用xmlrpc_method过滤器覆盖内置方法。如果你愿意,我可以发布代码。

没关系,我会发布代码......:)

我认为xmlrpc是可行的方式,这就是WP自己的应用程序连接的方式。为什么不使用它来获取帖子,为什么要使用RSS?
