案例一:小程序的图片处理

$file = request()->file('uploadimg'); //接收图片
        //创建图片存放位置
        $upload_dir = ROOT_PATH . 'public/upload/images/';
        if (!file_exists($upload_dir)) {
            mkdir($upload_dir, 0755, true);
        }
      
        if ($file) {
            // 移动到框架应用根目录/public/uploads/ 目录下
            $info = $file->rule('date')->move($upload_dir);
             if ($info) {
                //获取文件名
                 $image_name = $info->getSaveName();
                 $fileurl = '/upload/images/'. $image_name;
                 return  $fileurl;
            }
        }else{
            echo "错误";
        }



案例二:base64图片处理方法
class Image extends Base
{
    public function addimage($file = 'images')
    {
        $img_url    = input('avatar') ? input('avatar') : "";
        if ($img_url) {
　　　　　　　//如果是http格式的不需要处理直接返回
            if (substr($img_url, 0, 4) == 'http') {
                $src = $img_url;
                return $src;
                exit;
            } else {
                //处理图片
                $image_arr  = explode(',', $img_url);
                $img_data   = $image_arr[1];
                $img        = str_replace(' ', '+', $img_data);
                $fileData   = base64_decode($img);
                $image_name = uniqid() . '.png';  //返回13位字符串
                $upload_dir = ENV::get('root_path') . 'public/upload/' . $file . '/';
                if (!file_exists($upload_dir)) {
                    mkdir($upload_dir, 0755, true);
                }
                $filedir = $upload_dir . '/' . $image_name;
                $src = config('website') . '/upload/' . $file . '/' . $image_name;
                $status = file_put_contents($filedir, $fileData);
                if ($status) {
