How do I resize image using intervention before storing to s3?
提问by Hymanjoesmith
I'm saving the image to s3 and the s3 path to my database. I'm calling the path when I need to show the image. So right now I'm having trouble resizing that image before saving it to s3. I get this error message:
我将图像保存到 s3 并将 s3 路径保存到我的数据库。当我需要显示图像时，我正在调用路径。所以现在我在将其保存到 s3 之前无法调整该图像的大小。我收到此错误消息：
Command (getRealPath) is not available for driver (Gd).
this is what my controller looks like
这就是我的控制器的样子
public function up(Request $request) {
$user = $request->user();
$image= $request->file('images');
if(!empty(($image))){
$files = Input::file('images');
foreach($files as $file) {
if(!empty($file)){
$ext = $file->getClientOriginalExtension();
$media = ($user->media->where('category','profile')->first());
if($media == null){
$media = new Media();
$media->category='profile';
}
$this->saveMedia($media, $user,$file);
}
}
return Redirect::back()->with('message','Your profile has been updated');
}
}
private function saveMedia($media, $user, $file){
$ext = $file->getClientOriginalExtension();
$key = strtotime('now') . '.' . $ext;
$id = $user->id;
$url = 'https://s3-us-west-2.amazonaws.com/makersbrand/' . $id . '/' . $media->category . '/';
$media->user_id = $user->id;
$media->path = $url . $key;
$this->fillMedia($media,$user,$file, $key);
$media->save();
}
private function fillMedia($media, $user, $file, $key)
{
$file = Image::make($file)->resize(200,200);
$s3 = AWS::createClient('s3');
$result = $s3->putObject(array(
'Bucket' => self::$_BUCKET_NAME,
'Key' => $user->id . '/'. $media->category .'/'. $key,
'SourceFile' => $file->getRealPath(),
'Metadata' => array(
'Owner' => $user->first_name .' ' . $user->last_name
)
));
}
UpdateI don't think my images even get resized properly before it hits the getClientOriginalExtension error. When I do var_dump after resizing, I get this text:
更新我认为我的图像在遇到 getClientOriginalExtension 错误之前甚至没有正确调整大小。当我在调整大小后执行 var_dump 时，我得到以下文本：

Result is null. Format is null. image is Null. What am I doing wrong here?
结果为空。格式为空。图像为空。我在这里做错了什么？
updateI moved Image::make to my saveMedia function. Now I get
更新我将 Image::make 移动到我的 saveMedia 函数。现在我得到
Command (getRealPath) is not available for driver (Gd).

To get this working I used the following code within my Laravel 5 codebase;
为了让它工作，我在我的 Laravel 5 代码库中使用了以下代码；
$imageFile = \Image::make($uploadedFile)->resize(600, 600)->stream();
$imageFile = $imageFile->__toString();
$filename = 'aUniqueFilename.png';
$s3 = \Storage::disk('s3');
$s3->put('/'.$filename, $imageFile, 'public');

This error cause by class \Intervention\Image\Image doesn't support method getRealPath()
由类 \Intervention\Image\Image 引起的此错误不支持方法 getRealPath()
Solution: create a wrapper class to implement getRealPath()
解决方法：创建一个包装类来实现getRealPath()
use \Intervention\Image\Image as InterventionImage;
class ImageFile
{
/**
* Intervention image instance.
*
* @var \Intervention\Image\Image
*/
private $image;
function __construct(InterventionImage $image)
{
$this->image = $image;
}
function getRealPath()
{
return $this->image->basePath();
}
}
Usage:
用法：
$image = new ImageFile(InterventionImage::make($file->path())->fit(300, 200)->save());
$s3Key = Storage::disk('s3')->putFileAs('my_s3_image_folder', $image, 'my_image_file_name.jpg', 'public');
// Save your s3 Key to your database or whatever...

It seems like the driver you are using (gd) does not support a particular method (getClientOriginalExtension) the only solution in your case is to use a php function to get the extension from file name:
您使用的驱动程序 (gd) 似乎不支持特定方法 (getClientOriginalExtension)，您的情况的唯一解决方案是使用 php 函数从文件名中获取扩展名：
$ext = pathinfo($filePath, PATHINFO_EXTENSION);
$ext = pathinfo($filePath, PATHINFO_EXTENSION);

The main error here - you're passing a wrong object (Intervention\Image\Image) instead of File.
这里的主要错误 - 您传递了错误的对象 ( Intervention\Image\Image) 而不是 File。
In your case should work something like this:
在你的情况下应该是这样的：
private function fillMedia($media, $user, $file, $key)
{
$image = Image::make($file)->resize(200,200);
$s3 = AWS::createClient('s3');
$result = $s3->putObject(array(
'Bucket' => self::$_BUCKET_NAME,
'Key' => $user->id . '/'. $media->category .'/'. $key,
// use 'Body' option to put resized image content instead of 'SourceFile'
// fyi, your resized image wasn't saved to the original file
'Body' => $image->__toString(),
'Metadata' => array(
'Owner' => $user->first_name .' ' . $user->last_name
)
));
}
