base64_encode 图片转成code

图片base64编码:

public function base64EncodeImage($image_file)
    {
        #$image_file文件地址,就对路径或者网络访问路径都可以
        $base64_image = '';
        $image_info = getimagesize($image_file);
        $image_data = fread(fopen($image_file, 'r'), filesize($image_file));
        $base64_image = 'data:' . $image_info['mime'] . ';base64,' . chunk_split(base64_encode($image_data));
        return $base64_image;
    }

图片base64解码并存储:

try {
            $code_arr = substr($encodedstring, strpos($encodedstring, ",") + 1);
            $size = Storage::disk('local_ftp_root')->put($full_path, base64_decode(chunk_split($code_arr)));
            $url = Storage::disk('local_ftp_root')->url($full_path);
            return $this->outPutJson($url);
        } catch (\Exception $e) {
            return $this->outPutJson('', 201, $e->getMessage());
        }
