2.代码示例

            $ext = $files->getClientOriginalExtension();//得到图片的文件后缀 如:jpg
            $destinationPath = 'uploads/xcx/' . date('Ymd') . '/';//构建新的保存路径
            $fileName = uniqid() . '.' . $ext;//构建唯一名称
            //todo 文件路径如果不存在不能自动创建问题
            if (!is_dir($destinationPath)){
                mkdir(public_path().'/'.($destinationPath), 0777, true);
            }

            $image=new \Imagick($files->getRealPath());
            $image->setImageCompressionQuality(50);//设置质量
            //$image->cropThumbnailImage($image->getImageWidth()*0.5,$image->getImageHeight()*0.5);//等比例重置大小
            $image->writeImage($destinationPath . $fileName);//保存到新路径
