typecho插件编写教程(五):核心代码_PHP
之前啰嗦了很多,现在开始写核心代码。
分析一下,发布文章的时候,我们需要的信息就是当前文章的URL,我们需要想办法从$contents、 $class中拿到他。
目前我们的插件类代码如下(请注意render被我改成了send)
代码如下:
class BaiduSubmitTest_Plugin implements Typecho_Plugin_Interface
{
public static function activate(){
//挂载发布文章和页面的接口
Typecho_Plugin::factory('Widget_Contents_Post_Edit')->finishPublish = array('BaiduSubmitTest_Plugin', 'send');
Typecho_Plugin::factory('Widget_Contents_Page_Edit')->finishPublish = array('BaiduSubmitTest_Plugin', 'send');
return '插件安装成功,请进入设置填写准入密钥';
}
public static function deactivate(){
// do something
return '插件卸载成功';
}
public static function config(Typecho_Widget_Helper_Form $form){
$element = new Typecho_Widget_Helper_Form_Element_Text('api', null, null, _t('准入秘钥'), '请登录百度站长平台获取');
$form->addInput($element);
}
public static function personalConfig(Typecho_Widget_Helper_Form $form){}
public static function send($contents, $class){
//do something
}
}
获取URL
获取永久链接需要通过路由规则 + Typecho_Common::url 联合生成!
代码如下:
class BaiduSubmitTest_Plugin implements Typecho_Plugin_Interface
{
public static function activate(){
//挂载发布文章和页面的接口
Typecho_Plugin::factory('Widget_Contents_Post_Edit')->finishPublish = array('BaiduSubmitTest_Plugin', 'send');
Typecho_Plugin::factory('Widget_Contents_Page_Edit')->finishPublish = array('BaiduSubmitTest_Plugin', 'send');
return '插件安装成功,请进入设置填写准入密钥';
}
public static function deactivate(){
// do something
return '插件卸载成功';
}
public static function config(Typecho_Widget_Helper_Form $form){
//保存接口调用地址
$element = new Typecho_Widget_Helper_Form_Element_Text('api', null, null, _t('接口调用地址'), '请登录百度站长平台获取');
$form->addInput($element);
}
public static function personalConfig(Typecho_Widget_Helper_Form $form){}
/**
* 准备数据
* @param $contents 文章内容
* @param $class 调用接口的类
* @throws Typecho_Plugin_Exception
*/
public static function send($contents, $class){
//如果文章属性为隐藏或滞后发布
if( 'publish' != $contents['visibility'] || $contents['created'] > time()){
return;
}
//获取系统配置
$options = Helper::options();
//判断是否配置好API
if( is_null($options->plugin('BaiduSubmitTest')->api) ){
return;
}
//获取文章类型
$type = $contents['type'];
//获取路由信息
$routeExists = (NULL != Typecho_Router::get($type));
//生成永久连接
$path_info = $routeExists ? Typecho_Router::url($type, $contents) : '#';
$permalink = Typecho_Common::url($path_info, $options->index);
}
}
代码中有注释,老高就不在赘述了。
至此我们已经拿到了文章的永久链接,下一步就是给百度服务器发送数据了!
本节完!

After rain in summer, you can often see a beautiful and magical special weather scene - rainbow. This is also a rare scene that can be encountered in photography, and it is very photogenic. There are several conditions for a rainbow to appear: first, there are enough water droplets in the air, and second, the sun shines at a low angle. Therefore, it is easiest to see a rainbow in the afternoon after the rain has cleared up. However, the formation of a rainbow is greatly affected by weather, light and other conditions, so it generally only lasts for a short period of time, and the best viewing and shooting time is even shorter. So when you encounter a rainbow, how can you properly record it and photograph it with quality? 1. Look for rainbows. In addition to the conditions mentioned above, rainbows usually appear in the direction of sunlight, that is, if the sun shines from west to east, rainbows are more likely to appear in the east.
