typecho插件编写教程(一):Hello World,typechohello
最近老高正在编写一个关于typecho的插件,由于typecho不像wordpress,有那么多的文档参考,写一个插件还是遇到了很多的坑,不过随着研究的不断深入,老高也慢慢上手了,于是总结出此篇编写教程分享给大家!
I. 从HelloWorld说起
基本信息
想必想要开发typecho的你一定阅读过官方示例插件HelloWorld的源码吧?
我们先看看usr/plugins/HelloWorld/Plugin.php文件前几行
复制代码 代码如下:
if (!defined('__TYPECHO_ROOT_DIR__')) exit;
/**
* Hello World
*
* @package HelloWorld
* @author qining
* @version 1.0.0
* @link http://typecho.org
*/
...
...
这几行代码是一个插件的基本信息,我们由代码可以得出以下与插件相关的基本信息
插件说明 ---> Hello World
插件包名 ---> HelloWorld
插件作者 ---> qining
插件版本 ---> 1.0.0
插件链接 ---> http://typecho.org
同时这些信息都会显示在插件页中,如下图
插件结构
我们继续向后面的代码看,一个最简单的插件结构如下(为了缩短篇幅,老高移除了具体方法的实现)
每个方法基本都有注释,老高不再赘述。
看起来很简单吧?其实里面还是有不少坑的。
复制代码 代码如下:
class HelloWorld_Plugin implements Typecho_Plugin_Interface
{
/**
* 激活插件方法,如果激活失败,直接抛出异常
*
* @access public
* @return void
* @throws Typecho_Plugin_Exception
*/
public static function activate(){}
/**
* 禁用插件方法,如果禁用失败,直接抛出异常
*
* @static
* @access public
* @return void
* @throws Typecho_Plugin_Exception
*/
public static function deactivate(){}
/**
* 获取插件配置面板
*
* @access public
* @param Typecho_Widget_Helper_Form $form 配置面板
* @return void
*/
public static function config(Typecho_Widget_Helper_Form $form){}
/**
* 个人用户的配置面板
*
* @access public
* @param Typecho_Widget_Helper_Form $form
* @return void
*/
public static function personalConfig(Typecho_Widget_Helper_Form $form){}
/**
* 插件实现方法
*
* @access public
* @return void
*/
public static function render(){}
}
插件流程
插件的基本流程是这样的。
1.当我们的插件写好后会出现在后台
2.点击启用按钮后,会执行对应插件类的activate方法
3.插件与目标插件点关联,等待触发
4.当点击停用的时候调用deactivate方法
本节完。
下一节老高会更详细的说明插件类的方法。

How to use C# to write a Bloom filter algorithm. The Bloom Filter (BloomFilter) is a very space-efficient data structure that can be used to determine whether an element belongs to a set. Its basic idea is to map elements into a bit array through multiple independent hash functions and mark the bits of the corresponding bit array as 1. When judging whether an element belongs to the set, you only need to judge whether the bits of the corresponding bit array are all 1. If any bit is 0, it can be judged that the element is not in the set. Bloom filters feature fast queries and
