全局配置
使用QueryList全局配置,避免重复操作。
QueryList的config()
方法可用于全局配置QueryList。
使用场景:比如在项目中全局注册QueryList插件,这样在项目中任何位置都可以直接使用这些插件,避免重复注册操作。
示例
在项目的启动文件中全局注册一些QueryList插件和扩展一些功能,以Laravel
框架为例,在AppServiceProvider.php
文件的boot()
方法中全局配置QueryList:
php
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use QL\QueryList;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
// 全局注册插件
QueryList::config()->use(My\MyPlugin::class,$arg1,$arg2,$arg3)
->use([
My\MyPlugin1::class,
My\MyPlugin2::class,
Other\OtherPlugin::class
]);
//全局注册一个自定义的编码转换方法
QueryList::config()->bind('myEncode',function($outputEncoding,$inputEncoding){
$html = iconv($inputEncoding,$outputEncoding.'//IGNORE',$this->getHtml());
$this->setHtml($html);
return $this;
});
}
/**
* Register any application services.
*
* @return void
*/
public function register()
{
//
}
}
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use QL\QueryList;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
// 全局注册插件
QueryList::config()->use(My\MyPlugin::class,$arg1,$arg2,$arg3)
->use([
My\MyPlugin1::class,
My\MyPlugin2::class,
Other\OtherPlugin::class
]);
//全局注册一个自定义的编码转换方法
QueryList::config()->bind('myEncode',function($outputEncoding,$inputEncoding){
$html = iconv($inputEncoding,$outputEncoding.'//IGNORE',$this->getHtml());
$this->setHtml($html);
return $this;
});
}
/**
* Register any application services.
*
* @return void
*/
public function register()
{
//
}
}
之后就可以在项目的任何位置使用QueryList时都可以直接使用这些已注册的扩展功能了:
php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use QL\QueryList;
class IndexController extends Controller
{
public function index()
{
$data = QueryList::get('...')->myPlugin1('...')->rules('...')->queryData();
$data = QueryList::get('https://top.etao.com')->myEncode('UTF-8','GBK')->find('a')->texts();
}
}
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use QL\QueryList;
class IndexController extends Controller
{
public function index()
{
$data = QueryList::get('...')->myPlugin1('...')->rules('...')->queryData();
$data = QueryList::get('https://top.etao.com')->myEncode('UTF-8','GBK')->find('a')->texts();
}
}
