本文主要介绍了ThinkPHP中的行为扩展和插件原理分析、ThinkPHP中的行为、自定义行为、自定义插件等,给大家提供参考,希望对大家有所帮助。

原理分析

将标签与类之间的对应关系(如'app_init'=>array('Common\Behavior\InitHook')),通过Hook类中import或add方法,加载到Hook类中静态变量$tags中。当执行Hook中静态方法listen或者exec方法的时候(listen方法中调用了exec),实例化标签对应的类,调用相应的方法(如果是插件,调用传递的方法,如果是行为,调用run方法)。
Hook中exec方法定义如下:

 static public function exec($name, $tag,&$params=NULL) {
        if(false === strpos($name,'\\')) {            // 插件(多个入口)
            $class   =  "Addons\\{$name}\\{$name}Addon";
        }else{            // 行为扩展(只有一个run入口方法)
            $class   =  $name.'Behavior';            $tag    =   'run';
        }        $addon   = new $class();        return $addon->$tag($params);
    }

   ThinkPHP中的行为    加载标签与类之间的对应关系

// 加载模式行为定义

if(isset($mode['tags'])) {
    Hook::import(is_array($mode['tags'])?$mode['tags']:include $mode['tags']);
}// 加载应用行为定义if(is_file(CONF_PATH.'tags.php'))    // 允许应用增加开发模式配置定义
    Hook::import(include CONF_PATH.'tags.php');

模式行为对应关系

在ThinkPHP/Mode/common.php中tags标签中定义

'tags'  =>  array(        'app_begin'     =>  array(            'Behavior\ReadHtmlCache', // 读取静态缓存
        ),        'app_end'       =>  array(            'Behavior\ShowPageTrace', // 页面Trace显示
        ),        'view_parse'    =>  array(            'Behavior\ParseTemplate', // 模板解析 支持PHP、内置模板引擎和第三方模板引擎
        ),        'template_filter'=> array(            'Behavior\ContentReplace', // 模板输出替换
        ),        'view_filter'   =>  array(            'Behavior\WriteHtmlCache', // 写入静态缓存
        ),
    )

应用行为对应关系

在Application/Common/Conf/tags.php中定义

调用相应的行为

Hook::listen('app_begin')相当于调用Behavior\ReadHtmlCache中的run方法。找到该类,可以查看其对应的run方法如下

自定义行为    1.在Application/Common/Conf/tags.php中添加对应关系

'dqs_behavior'=>array('Common\Behavior\Dqs')

将对应关系添加到tags.php,程序会自动将其加载到Hook的$tags变量中,当然也可通过使用Hook中的add方法手动加载。

2.定义Common\Behavior\DqsBehavior类

<?phpnamespace Common\Behavior;use Think\Behavior;

defined(&#39;THINK_PATH&#39;) or exit();class DqsBehavior extends Behavior {

    public function run(&$content){
        echo &#39;<pre class="brush:php;toolbar:false">&#39;;
        print_r(&#39;调用了行为Dqs&#39;);        echo &#39;
';     } }

其中Behavior 类为ThinkPHP自带的抽象类

3.调用行为

自定义插件    1.定义插件文件

通过查看Hook文件中插件类实例化方式($class   =  "Addons\\{$name}\\{$name}Addon";),可以得知,如果想定义一个名为Dqs的插件,应该在Addons/Dqs目录下定义DqsAddon.class.php文件。程序如下:

<?phpnamespace Addons\Dqs;class DqsAddon{   
    public $info = array(            &#39;name&#39;=>&#39;Editor&#39;,            &#39;title&#39;=>&#39;dqs测试插件&#39;,            &#39;description&#39;=>&#39;主要用于输出&#39;,            &#39;status&#39;=>1,            &#39;author&#39;=>&#39;lidequan&#39;,            &#39;version&#39;=>&#39;0.1&#39;
    );    public  function dqsTrace($pa){
        echo &#39;<pre class="brush:php;toolbar:false">&#39;;
        print_r($pa);        echo &#39;
';     } }

   2.注册插件

所谓的注册插件,就是将插件的标签与类之间的对应关系,添加到Hook类中静态变量$tags中。对应行为来说,标识符仅仅是一个标识符,可以定义任意的标识符,但是对应插件来说,标识符不能随意定义,因为插件的标识符代表的是插件的方法名。所以上面的插件注册代码如下

\Think\Hook::add(&#39;dqsTrace&#39;,array(&#39;Dqs&#39;));

   3.调用插件

$params=array(&#39;name&#39;=>&#39;dqs&#39;);
\Think\Hook::listen(&#39;dqsTrace&#39;,$params);

效果如下

Hook中exec方法定义如下:

 static public function exec($name, $tag,&$params=NULL) {
        if(false === strpos($name,&#39;\\&#39;)) {            // 插件(多个入口)
            $class   =  "Addons\\{$name}\\{$name}Addon";
        }else{            // 行为扩展(只有一个run入口方法)
            $class   =  $name.&#39;Behavior&#39;;            $tag    =   &#39;run&#39;;
        }        $addon   = new $class();        return $addon->$tag($params);
    }

   ThinkPHP中的行为    加载标签与类之间的对应关系

// 加载模式行为定义

if(isset($mode[&#39;tags&#39;])) {
    Hook::import(is_array($mode[&#39;tags&#39;])?$mode[&#39;tags&#39;]:include $mode[&#39;tags&#39;]);
}// 加载应用行为定义if(is_file(CONF_PATH.&#39;tags.php&#39;))    // 允许应用增加开发模式配置定义
    Hook::import(include CONF_PATH.&#39;tags.php&#39;);

模式行为对应关系

在ThinkPHP/Mode/common.php中tags标签中定义

&#39;tags&#39;  =>  array(        &#39;app_begin&#39;     =>  array(            &#39;Behavior\ReadHtmlCache&#39;, // 读取静态缓存
        ),        &#39;app_end&#39;       =>  array(            &#39;Behavior\ShowPageTrace&#39;, // 页面Trace显示
        ),        &#39;view_parse&#39;    =>  array(            &#39;Behavior\ParseTemplate&#39;, // 模板解析 支持PHP、内置模板引擎和第三方模板引擎
        ),        &#39;template_filter&#39;=> array(            &#39;Behavior\ContentReplace&#39;, // 模板输出替换
        ),        &#39;view_filter&#39;   =>  array(            &#39;Behavior\WriteHtmlCache&#39;, // 写入静态缓存
        ),

    );    public  function dqsTrace($pa){

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
