【中文标题】带有 Trait 的 Laravel 控制台命令【英文标题】:Laravel Console Command with a Trait 【发布时间】:2019-10-23 02:41:05 【问题描述】:我已经为我正在处理的 Trait 设置了一些配置变量,其中一个是 data_format
变量,它可以是 json 或 xml。
它是这样设置的:
$this->data_format = config('rightmove.FORMAT');
在控制器中,我可以运行 dd($this->data_format) 并返回:“json”
我已经将此作为控制台命令,但是当我尝试使用 dd 为 $this->data_format
运行控制台命令时,它会返回
空
以及随后我的其余代码错误。
我已经运行了php artisan config:cache
命令来清除缓存,但控制台似乎没有拾取该配置变量?
我的App\Console\Commands\UpdateRightMove
如下所示:
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
use Carbon\Carbon;
use Illuminate\Http\Request;
use App\Traits\RightMoveTrait;
use App\Property;
use Illuminate\Support\Facades\Cache;
use Illuminate\Support\Facades\Log;
use QCod\AppSettings\Setting\AppSettings;
class UpdateRightmove extends Command
use RightMoveTrait;
private $is_set;
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'rightmove:update';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Updates Rightmove - Creates / Updates and Deletes properties from the Rightmove API';
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
parent::__construct();
$this->is_set = setting('rightmove');
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
if($this->is_set == 1)
// Rightmove is Enabled via settings (Run Command)...
$now = Carbon::now();
// Check App Cache for Last Time RightMove Artisan Command was Ran...
//$last_ran = cache('rightmove_update');
$last_ran = '2019-06-07 14:52:40';
if($last_ran == NULL)
// Send ALL Properties to Rightmove, First Time Ran....
$properties = Property::whereNotNull('ref')
->where('beds', '>', 0 )
->where('price', '>', 0)
->where('name', '!=', '')
->where('city', '!=', '')
->whereRaw('LENGTH(postcode) >= 5')
->get();
else
$from_date = Carbon::now();
// Get a Difference between last ran and now...
$time_diff = $from_date->diffInHours($last_ran);
// This will run and get properties that have changed since the last task ran
$to_date = Carbon::now()->subHours($time_diff);
// Get Filtered Properties & One's added / updated in last 12 hours...
$properties = Property::whereNotNull('ref')
->where('beds', '>', 0 )
->where('price', '>', 0)
->where('name', '!=', '')
->where('city', '!=', '')
->whereRaw('LENGTH(postcode) >= 5')
->whereBetween('created_at', [$to_date, $from_date])
->orWhereBetween('updated_at', [$to_date, $from_date])
->get();
// Get Settings....
if(setting('overseas') == 0)
// UK Based....
$this->update_feed_uk($properties);
else
// Overseas....
Cache::rememberForever('rightmove_update', function()
return now()->toDateTimeString();
);
我的RightMoveTrait
如下:
<?php
namespace App\Traits;
use Carbon\Carbon;
use Illuminate\Support\Facades\DB;
use App\Property;
use App\PropertyType;
use Illuminate\Support\Facades\Log;
use Illuminate\Support\Facades\Storage;
trait RightMoveTrait
private $network_id;
private $branch_id;
private $data_format;
private $environment;
private $allow_delete;
private $current_time;
public function __construct()
$this->network_id = config('rightmove.NETWORK_ID');
$this->branch_id = config('rightmove.BRANCH_ID');
$this->data_format = config('rightmove.FORMAT');
$this->allow_delete = config('rightmove.ALLOW_DELETE');
$this->environment = config('rightmove.ENVIRONMENT');
$now = Carbon::now();
$this->current_time = $now;
$this->refs = [];
function update_feed_uk($properties)
dd($this->data_format);
编辑 控制台运行似乎跳过了特征中的 __construct
。因此,在 Console 命令 (UpdateRightMove
) 的构造方法中,我添加了变量,它可以正常工作。
public function __construct()
parent::__construct();
$this->is_set = setting('rightmove');
$this->network_id = config('rightmove.NETWORK_ID');
$this->branch_id = config('rightmove.BRANCH_ID');
$this->data_format = config('rightmove.FORMAT');
$this->allow_delete = config('rightmove.ALLOW_DELETE');
$this->environment = config('rightmove.ENVIRONMENT');
$now = Carbon::now();
$this->current_time = $now;
$this->refs = [];
【问题讨论】:
在您的 app/Console/Kernel.php 通过将\Artisan::command('test', function () $this->info(config('rightmove.FORMAT')););
添加到方法 commands()
中,当您执行 php artisan test
时,它是否会在您的控制台中返回 json
?
另外,我们可以看看你的RightMoveTrait
吗?
这不能被试图帮助你的人复制,请包括 trait 和 config,这样会更容易。
是的,会的。我不在办公桌前,打算回来
嗨,我已经添加了。
【参考方案1】:
不会调用您的 trait 的 __construct()
函数,因为该类使用自己的 __construct()
函数。
在您的UpdateRightmove
班级中:
use RightMoveTrait
RightMoveTrait::__construct as private _rightMoveTraitConstruct;
public function __construct()
parent::__construct();
$this->_rightMoveTraitConstruct();
$this->is_set = setting('rightmove');
