前后端分离 前台传base64的图片 tp5.1.1进行处理

话不多说，直接上代码

public function image(Request $request){
        $param = $request->param();
//目录的upload文件夹下
        $up_dir = "uploads/".date('Ymd', time()) . "/";  //创建目录
        if(!file_exists($up_dir)){
            mkdir($up_dir,0777,true);
        }
        $base64_img = trim($param['image']);
 
        if(preg_match('/^(data:s*image/(w+);base64,)/', $base64_img, $result)){
            $type = $result[2];
            if(in_array($type,array('pjpeg','jpeg','jpg','gif','bmp','png'))){
                $new_file = $up_dir.time().'.'.$type;
                if(file_put_contents($new_file, base64_decode(str_replace($result[1], '', $base64_img)))){
                    $img_path = str_replace('../../..', '', $new_file);
                    return json(array('code'=>0,'data'=>$img_path,'msg'=>'成功'));
                }else{
                    return json(array('code'=>1,'data'=>'','msg'=>'图片上传失败'));
                }
            }else{
                //文件类型错误
                return json(array('code'=>1,'data'=>'','msg'=>'图片上传类型错误'));
            }
        }
    }
