Question

我创建了控制器IndexController和FontCorrector。我想在IndexController中使用FontCorrector方法。我的FontCorrector代码：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FontCorrector extends Controller
{

    public function ConvertToDefault($text)  // Convert To Default
    {
        $search  = array("ғ","ӣ","ҷ","ҳ","қ","ӯ");
        $replace = array("г","и","ч","х","к","у");

        $result  = str_replace($search, $replace, $text);

        $search  = array("Ғ","Ӣ","Ҷ","Ҳ","Қ","Ӯ");
        $replace = array("Г","И","Ч","Х","К","У");

        $result  = str_replace($search, $replace, $result);

        $search  = array("ѓ","ї","љ","њ","ќ","ў");
        $replace = array("г","и","ч","х","к","у");

        $result  = str_replace($search, $replace, $result);

        $search  = array("Ѓ","Ї","Љ","Њ","Ќ","Ў");
        $replace = array("Г","И","Ч","Х","К","У");

        $result  = str_replace($search, $replace, $result);

        return $result;
    }

    public function ctd($text)
    {
        $text = $this->ConvertToDefault($text);

        return $text;
    }
?>

这里我的IndexController和我的方法调用正在调用没有成功调用的FontCorrector控制器方法：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\FontCorrector as fc;

class IndexController extends Controller
{
    public function exec(Request $request)
    {

        if($request->input('lang-input') !== null)
        {
            echo fc::ctd($request->input('lang-input'));
        }

        return view("index");
    }
}
?>

ErrorException：“不应静态调用非静态方法App \ Http \ Controllers \ FontCorrector :: ctd（）”

Answer 1

你可以像这样打电话

$fc = new FontCorrector;
echo $fc->ctd($request->input('lang-input');

但是有更好的方法可以为此做出特质

就像你的app/Traits/FontCorrector.php创建文件一样

FontCorrector.php

中的

public function ConvertToDefault($text)  // Convert To Default
{
    ...

    return $result;
}

public function ctd($text)
{
    $text = $this->ConvertToDefault($text);

    return $text;
}

并在 IndexController

中

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Traits\FontCorrector;

class IndexController extends Controller
{
    use FontCorrector;

    public function exec(Request $request)
    {

        if($request->input('lang-input') !== null)
        {
            echo $this->ctd($request->input('lang-input')); // call it 
        }

        return view("index");
    }
}

有多种方法可以解决这个问题，但我会给你最简单的最脏的方法，但这与面向对象的编程有很大关系，而不是Laravel。

在调用方法之前，您需要在代码中实例化FontCorrector。因为ctd（）不是静态方法。

您可以通过编辑 IndexController 来执行此操作：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\FontCorrector as fc;

class IndexController extends Controller
{
    public function exec(Request $request)
    {

        if($request->input('lang-input') !== null)
        {
            $fc_obj = new fc;
            echo $fc_obj->ctd($request->input('lang-input'));
        }

        return view("index");
    }
}
?>

这样做有很多不妥之处，但我知道你宁愿在其他任何事情之前有所作为。

建议不要在另一个控制器中调用或实例化控制器实例，因为您可以使用自定义helper。但是，如果你真的想这样做，那么在你的SELECT (exchange || ':' || pair) AS id, exchange, c.pair, c.high AS high, c.low AS low, c.open AS open, c.closing AS close, c.volume AS volume, c.opened_at, c.closed_at, 86400 AS interval FROM ( SELECT exchange, pair, FIRST_VALUE(closed_at) OVER ( PARTITION BY exchange, pair, floor(EXTRACT(epoch FROM closed_at) / (86400)) ORDER BY closed_at ) opened_at, LAST_VALUE(closed_at) OVER ( PARTITION BY exchange, pair, floor(EXTRACT(epoch FROM closed_at) / (86400)) ORDER BY closed_at ) closed_at, FIRST_VALUE(open) OVER ( PARTITION BY exchange, pair, floor(EXTRACT(epoch FROM closed_at) / (86400)) ORDER BY closed_at ) open, MAX(high) OVER ( PARTITION BY exchange, pair, floor(EXTRACT(epoch FROM closed_at) / (86400)) ORDER BY closed_at ) high, MIN(low) OVER ( PARTITION BY exchange, pair, floor(EXTRACT(epoch FROM closed_at) / (86400)) ORDER BY closed_at ) low, LAST_VALUE(close) OVER ( PARTITION BY exchange, pair, floor(EXTRACT(epoch FROM closed_at) / (86400)) ORDER BY closed_at ) closing, SUM(volume) OVER ( PARTITION BY exchange, pair, floor(EXTRACT(epoch FROM closed_at) / (86400)) ORDER BY closed_at ) volume FROM candles WHERE exchange = 'gdax' AND pair = 'ethusd' AND closed_at > '2017-10-01 10:00:00' AND volume > 0 ) c WHERE EXTRACT(epoch FROM closed_at) - EXTRACT(epoch FROM opened_at) = ((86400 - (1 * 60))) ORDER BY closed_at DESC中，你可以使用laravel依赖注入，我认为这是更好的方法。

您需要初始化＆＃34; ConvertToDefault＆＃34;和＆＃34; ctd＆＃34;作为＆＃34;公共静态函数＆＃34;因为你是从另一个控制器访问它。

尝试这种方式：

public static function ConvertToDefault($text)  // Convert To Default
{
    $search  = array("ғ","ӣ","ҷ","ҳ","қ","ӯ");
    $replace = array("г","и","ч","х","к","у");

    $result  = str_replace($search, $replace, $text);

    $search  = array("Ғ","Ӣ","Ҷ","Ҳ","Қ","Ӯ");
    $replace = array("Г","И","Ч","Х","К","У");

    $result  = str_replace($search, $replace, $result);

    $search  = array("ѓ","ї","љ","њ","ќ","ў");
    $replace = array("г","и","ч","х","к","у");

    $result  = str_replace($search, $replace, $result);

    $search  = array("Ѓ","Ї","Љ","Њ","Ќ","Ў");
    $replace = array("Г","И","Ч","Х","К","У");

    $result  = str_replace($search, $replace, $result);

    return $result;
}

public static function ctd($text)
{
    $text = TestController::ConvertToDefault($text);

    return $text;
}
