这篇文章主要介绍Laravel中的管道的使用实例,文中介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们一定要看完!
一、控制器
路由器部分
Route::get('/pipe', ['as'=>'pipe', 'uses'=>'PipeController@index']);控制代码
<?php
namespace App\Http\Controllers;
use App\Pipes\LeftWords;
use App\Pipes\RightWords;
use App\Pipes\BothSidesWords;
use Illuminate\Http\Request;
use Illuminate\Pipeline\Pipeline;
use App\User;
use Illuminate\Support\Str;
use Illuminate\Support\Facades\Hash;
class PipeController extends Controller
{
/* 定义管道
*
* 第一步处理
* 第二部处理
* 第三部处理
* */
protected $pipes = [
LeftWords::class,
RightWords::class,
BothSidesWords::class,
];
// 首页
public function index(Request $request){
$name = $request->input('name');
// $name = Str::random(10);
return app(Pipeline::class)
->send($name)
->through($this->pipes)
->then(function ($content) {
return User::create([
'name' => $content,
'email'=>Str::random(10).'@gmail.com',
'password'=>Hash::make('password'),
]);
});
}
}二、管道部分
目录结构如下:
├─app
│ │ User.php
│ ├─Http
│ │ ...│ │
│ ├─Models
│ │ ...│ │
│ ├─Pipes
│ │ │ BothSidesWords.php
│ │ │ LeftWords.php
│ │ │ RightWords.php
│ │ │
│ │ └─Contracts
│ │ PipeContracts.php
<?php
namespace App\Pipes\Contracts;
use Closure;
interface PipeContracts
{
public function handle($body, Closure $next);
} <?php
namespace App\Pipes;
use App\Pipes\Contracts\PipeContracts;
use Closure;
class LeftWords implements PipeContracts{
public function handle($body, Closure $next)
{
// TODO: Implement handle() method.
$body = 'left-'.$body;
return $next($body);
}
}LeftWords.php的代码
<?php
namespace App\Pipes;
use App\Pipes\Contracts\PipeContracts;
use Closure;
class RightWords implements PipeContracts{
public function handle($body, Closure $next)
{
// TODO: Implement handle() method.
$body = $body.'-right';
return $next($body);
}
}BothSidesWords.php的代码
<?php
namespace App\Pipes;
use App\Pipes\Contracts\PipeContracts;
use Closure;
class BothSidesWords implements PipeContracts{
public function handle($body, Closure $next)
{
// TODO: Implement handle() method.
$body = '['.$body.']';
return $next($body);
}
}这里我们使用管道默认的方法handle,你可以自定义方法名。像下面这样定义myHandleMethod为处理方法名称。
return app(Pipeline::class)
->send($name)
->through($this->pipes)
->via('myHandleMethod')
->then(function ($content) {
return User::create([
'name' => $content,
'email'=>Str::random(10).'@gmail.com',
'password'=>Hash::make('password'),
]);
});你这样定义后,修改你的interface,同时修改你的实现类即可。
三、结果说明
访问http://localhost/pipe?name=lisa之后,能成功打印出获取的结果。User表内部,有数据保存成功。
{
"name": "[left-lisa-right]",
"email": "3riSrDuBFv@gmail.com",
"updated_at": "2020-09-05T05:57:14.000000Z",
"created_at": "2020-09-05T05:57:14.000000Z",
"id": 15
