Laravel图像上传验证

Question

I am trying to validate uploaded files using laravel validation but am having issues.

Here is my code:

$this->validate($request, [
        'image' =>'mimetypes:image/jpeg,image/png,image/gif',

        ]);

        $avatar = $request->file('image');

        $fileName = time(). '.' . $avatar->getClientOriginalExtension();
        Image::make($avatar)->resize(300,300)->save( public_path('uploads/avatar/' . $fileName));

        $user = Auth::user();
        $user->avatar = $fileName;
        $user->save();

The issue is when I use a bmp file, I get this error: Gd error

I am using the Intervention image package. I would rather not switch to the imagick driver.

Any ideas?

Looking at the Intervention package code, you can see two implementations to the processBmp function:

Intervention/Image/Gd/Encoder.php:

protected function processBmp()
{
    throw new \Intervention\Image\Exception\NotSupportedException(
        "BMP format is not supported by Gd Driver."
    );
}

Intervention/Image/Imagick/Encoder.php:

protected function processBmp()
{
    $format = 'bmp';
    $compression = \Imagick::COMPRESSION_UNDEFINED;
    $imagick = $this->image->getCore();
    $imagick->setFormat($format);
    $imagick->setImageFormat($format);
    $imagick->setCompression($compression);
    $imagick->setImageCompression($compression);
    return $imagick->getImagesBlob();
}

So I think it's safe to say that you can't do it with the GD driver, only with imagick.
