使用Yii将调整大小的图像上传到S3

我想使用Yii框架将调整大小的图像上传到Amazon S3存储桶，但要直接执行 - 无需将原始（未调整大小）图像上载到任何文件夹，网站或服务器结构。使用Yii将调整大小的图像上传到S3

我已使用ThumbsGen扩展名可创建图像的缩略图。如果我在自己的服务器上上传文件，代码将起作用。但是，如果我将图像上传到S3，那么它不会创建缩略图。

我的代码是这样的：

<?php 

Yii::app()->setComponents(array('ThumbsGen' => array(

     'class' => 'ext.ThumbsGen.ThumbsGen', 
     'thumbWidth' => Yii::t('constants', 'SECRETCODE_WIDTH'), 
     'thumbHeight' => Yii::t('constants', 'SECRETCODE_HEIGHT'), 
     'baseSourceDir' => Yii::app()->request->s3baseUrl.'/uploads/secretcode/original/', 
     'baseDestDir' => Yii::app()->request->s3baseUrl. '/uploads/secretcode/thumbs/', 
     'postFixThumbName' => null, 
     'nameImages' => array('*'), 
     'recreate' => false, 
))); 

class SecretCodeController extends MyController { 

     public function actionCreate() { 
     $model = new SecretCode; 
     $model->scenario = 'create'; 

     if (isset($_POST['SecretCode'])) { 
      $model->attributes = $_POST['SecretCode']; 
      $temp = $model->promo_image = CUploadedFile::getInstance($model, 'promo_image'); 

      if ($model->validate()) { 
       $rnd = rand(1, 1000); 
       $ext = $model->promo_image->extensionName; 
       $filename = 'secret_' . Yii::app()->user->app_id . '_' . time() . '_' . $rnd . '.' . $ext;      $success = Yii::app()->s3->upload($temp->tempName , 'uploads/secretcode/original/'.$filename); 

       if(!$success) 
       { 
        $model->addError('promo_image', Yii::t('constants', 'IMAGE_FAILURE')); 
       } else { 

        $model->promo_image = $filename; $model->promo_image = $filename; 
$fullImgSource = @Yii::app()->s3->getObject(Yii::app()->params->s3bucket_name,"uploads/secretcode/original/".$filename); 

        list($width, $height, $type, $attr) = getimagesize($fullImgSource->headers['size']); 
        $dimensions = array(); 

        $dimensions = CommonFunctions :: SetImageDimensions($width, $height,Yii::t('constants', 'SECRETCODE_WIDTH'), Yii::t('constants', 'SECRETCODE_HEIGHT')); 

        Yii::app()->ThumbsGen->thumbWidth = $dimensions['width']; 
        Yii::app()->ThumbsGen->thumbHeight = $dimensions['height']; 
        Yii::app()->ThumbsGen->createThumbnails(); 

       } 

        if ($model->save()) { 
         Yii::app()->user->setFlash('success', Yii::t('constants', 'Secret Code')." ". Yii::t('constants', 'ADD_SUCCESS')); 
         $this->redirect(array('create')); 
        } 
       } 
      } 
     } 

     $this->render('create', array(
      'model' => $model, 
     )); 
    } 
}

其结果是，我得到一个PHP警告：

getimagesize(42368) [<a href='function.getimagesize'>function.getimagesize</a>]: failed to open stream: No such file or directory

我在做什么错？

和getimagesize - 获取图像的大小

array getimagesize (string $filename [, array &$imageinfo ])

您的代码：

list($width, $height, $type, $attr) = getimagesize($fullImgSource->headers['size']);

$ fullImgSource->头[ '大小'] - 我怀疑它存储的文件路径，图像;

试试这个：

list($width, $height, $type, $attr) = $fullImgSource->headers['size'];

或

list($width, $height, $type, $attr) = getimagesize(/*path to image*/);
