Question

我想创建一个拇指，但我收到此错误：

PHP致命错误 - yii \ base \ ErrorException Class＆＃39; Imagine \ Image \ ManipulatorInterface＆＃39;找不到

我不知道从哪里可以得到这个？我使用了yii2-imagine，但没有找到任何ManipulatorInterface类。

控制器文件：

<?php
namespace backend\controllers;

use Yii;
use app\models\Employee;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\AccessControl;
use yii\filters\VerbFilter;
use yii\web\UploadedFile;
use yii\imagine\Image; // this is where i used Image class

public function actionCreate()
{
    $model = new Employee();
    $model->added_date_time = date('Y-m-d H:i:s');
    if($model->load(Yii::$app->request->post())) {
        $model->file = UploadedFile::getInstance($model,'avatar');

        if(!empty($model->file)) {
            $imageName = Yii::$app->security->generateRandomString();
            $model->file->saveAs('uploads/'.$imageName.'.'.$model->file->extension);
            $model->avatar = $imageName.'.'.$model->file->extension;
            $file = 'uploads/'.$imageName.'.'.$model->file->extension;
            Image::thumbnail($file, 200, 200)->save('uploads/thumb/', ['quality' => 80]);
        }
        if($model->save()){
            $this->redirect(\Yii::$app->urlManager->createUrl('employee'));
        }
    }
    else {
        return $this->render('create', [
            'model' =>  $model
            ]);
    }
}
?>

图片类文件位于\vendor\yiisoft\yii2\imagine文件夹中，ManipulatorInterface位于\vendor\yiisoft\yii2\imagine\Image文件夹中

Image.php

<?php
namespace yii\Imagine;
class Image extends BaseImage
{
}
?>

BaseImage.php

<?php

namespace yii\imagine;

use Yii;
use imagine\Image\Box;
use imagine\Image\Color;
use imagine\Image\ImageInterface;
use imagine\Image\ImagineInterface;
use imagine\Image\ManipulatorInterface;
use imagine\Image\Point;
use yii\base\InvalidConfigException;
use yii\base\InvalidParamException;
use yii\helpers\ArrayHelper;

class BaseImage
{
    public static function thumbnail($filename, $width, $height, $mode = 'outbound')
    {
        $box = new Box($width, $height);
        $img = static::getImagine()->open(Yii::getAlias($filename));

        if (($img->getSize()->getWidth() <= $box->getWidth() && $img->getSize()->getHeight() <= $box->getHeight()) || (!$box->getWidth() && !$box->getHeight())) {
            return $img->copy();
        }

        $img = $img->thumbnail($box, $mode);

        // create empty image to preserve aspect ratio of thumbnail
        $thumb = static::getImagine()->create($box, new Color('FFF', 100));

        // calculate points
        $size = $img->getSize();

        $startX = 0;
        $startY = 0;
        if ($size->getWidth() < $width) {
            $startX = ceil($width - $size->getWidth()) / 2;
        }
        if ($size->getHeight() < $height) {
            $startY = ceil($height - $size->getHeight()) / 2;
        }

        $thumb->paste($img, new Point($startX, $startY));

        return $thumb;
    }
?>

我有同样的问题。我尝试'composer global require“fxp / composer-asset-plugin：~1.0.0”'之后我再次尝试'composer.phar require --prefer-dist yiisoft / yii2-imagine'，这对我有用。希望它也能帮到你

Answer 2

你可以试试这个：

1）将想象复制到您的供应商

`pathA: "vendor/Imagine/Draw...."`

2）在config.php

中添加别名

'components' => [
],

 ....

'aliases'=>[
    '@Imagine'=>'@vendor/Imagine', //this should correspond to pathA above
 ],

 ....

'params' => [
 ],

3）检查vendor/composer/autoload_psr4.php 像这样配置

return array(
    ...

    'yii\\imagine\\' => array($vendorDir . '/yiisoft/yii2-imagine'),

    ...

);

4）将yii-imagine复制到yiisoft

pathB:"vendor/yiisoft/yii-imagine"

然后你可以使用它。

我决定在extensions.php文件夹下的yiisoft设置路径。

只需按照以下两个步骤操作：

打开extensions.php
在文件底部添加

  'yiisoft/yii2-imagine' => 
  array (
    'name' => 'yiisoft/yii2-imagine',
    'version' => '~2.0.0',
    'alias' => 
    array (
      '@yii/imagine' => $vendorDir . '/yiisoft/yii2-imagine',
      '@Imagine/Image' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Image',
      '@Imagine/Gd' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Gd',
      '@Imagine/Draw' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Draw',
      '@Imagine/Effects' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Effects',
      '@Imagine/Exception' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Exception',
      '@Imagine/Filter' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Filter',
      '@Imagine/Gmagick' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Gmagick',
      '@Imagine/Imagick' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Imagick',
      '@Imagine/resources' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/resources',
    ),
  ),

所以我的extensions.php看起来像

<?php

$vendorDir = dirname(__DIR__);

return array (
  'yiisoft/yii2-swiftmailer' => 
  array (
    'name' => 'yiisoft/yii2-swiftmailer',
    'version' => '2.0.6.0',
    'alias' => 
    array (
      '@yii/swiftmailer' => $vendorDir . '/yiisoft/yii2-swiftmailer',
    ),
  ),
  'yiisoft/yii2-bootstrap' => 
  array (
    'name' => 'yiisoft/yii2-bootstrap',
    'version' => '2.0.6.0',
    'alias' => 
    array (
      '@yii/bootstrap' => $vendorDir . '/yiisoft/yii2-bootstrap',
    ),
  ),
  'yiisoft/yii2-debug' => 
  array (
    'name' => 'yiisoft/yii2-debug',
    'version' => '2.0.6.0',
    'alias' => 
    array (
      '@yii/debug' => $vendorDir . '/yiisoft/yii2-debug',
    ),
  ),
  'yiisoft/yii2-gii' => 
  array (
    'name' => 'yiisoft/yii2-gii',
    'version' => '2.0.5.0',
    'alias' => 
    array (
      '@yii/gii' => $vendorDir . '/yiisoft/yii2-gii',
    ),
  ),
  'yiisoft/yii2-faker' => 
  array (
    'name' => 'yiisoft/yii2-faker',
    'version' => '2.0.3.0',
    'alias' => 
    array (
      '@yii/faker' => $vendorDir . '/yiisoft/yii2-faker',
    ),
  ),
  'yiisoft/yii2-imagine' => 
  array (
    'name' => 'yiisoft/yii2-imagine',
    'version' => '~2.0.0',
    'alias' => 
    array (
      '@yii/imagine' => $vendorDir . '/yiisoft/yii2-imagine',
      '@Imagine/Image' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Image',
      '@Imagine/Gd' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Gd',
      '@Imagine/Draw' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Draw',
      '@Imagine/Effects' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Effects',
      '@Imagine/Exception' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Exception',
      '@Imagine/Filter' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Filter',
      '@Imagine/Gmagick' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Gmagick',
      '@Imagine/Imagick' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Imagick',
      '@Imagine/resources' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/resources',
    ),
  ),
);

在Yii2中创建Thumb会出错
