  • 图片资源转化为二进制,在存储数据库中,并从数据库中获取和显示到html页面中

    主要讲解主要步骤:

    ###转化为二进制并存储数据:

    1.html页面,选择需要上传的文件:

    且表单上传设置为可上传文件

     

     

    2.另外的页面接收该数据;图片转化为二进制

    //$img=uploads($_FILES);
        $file_uploads = file_get_contents($_FILES['img']['tmp_name']);
        $img_file = base64_encode($file_uploads);//转化为二进制数据
        //$img_type_ext=$_FILES['img']['name']['extension'];
        $img_type_ext=pathinfo($_FILES['img']['name'])['extension'];//后缀名
        //判断用户名是否存在

    3.插入数据

        正常插入数据

    ####从数据库获取并中显示:

    1.重数据库中获取数据:(简单就不写了)

    2.在html中显示:

       <img src='image.php?id= {$row['id']}'> //row为从数据库中获取的一行记录,

    3.其中image.php文件为:

    <?php
        include('../../public/config.inc.php');
        // $id=3;
        $id     = $_GET['id'];
        $sql    = "select * from brand where id='$id'";
        $res = mysqli_query( $link,$sql);
        if (!$res)
            die("读取图片失败!");
        $num = mysqli_num_rows($res);
        if ($num < 1)
            die("暂无图片");
        $row=mysqli_fetch_assoc($res);

        $img_data=$row['img'];//获取图片二进制数据
        $img = base64_decode($img_data);  //Base64解码

        $type = $row['img_type'];//获取图片后缀名

        mysqli_close($link);

        Header("Content-type: $type");
        
        echo $img;
    ?>

  • 可以讲二进制数据存储到数据库中,也可以将base64位... * 上传图片,并且转化为二进制存储数据库, * mvc返回json会自动将二进制数据转化为base64位 * @param request * @param file * @return * @throws IOEx...

    前言:有时图片量不大的时候小刘想将图片存储到数据库中,不再使用物理地址了!关于MVC配置上传参数请之前写的博客!

    温馨提示:可以讲二进制数据存储到数据库中,也可以将base64位的数据存储到数据库中

    其他上传博客文如下:

    springMVC图片上传,单图片上传和多图片上传以及预览

    Ajax实现单图片上传,多图片上传,以及和对象的综合上传

    接口:

       /**多方测试一斤验证
         *
         * 上传图片,并且转化为二进制存储数据库,
         * mvc返回json会自动将二进制数据转化为base64位
         * @param request
         * @param file
         * @return
         * @throws IOException
         */
        @RequestMapping(value = "/uploadBase64")
        @ResponseBody
        public   Map<String,Object>  uploadBase64(HttpServletRequest request,
                                 @RequestParam("file") MultipartFile file) throws IOException {
            Map<String,Object>map=new HashMap<>();
            byte[] bytes = file.getBytes();
            System.out.println("二进制数据"+bytes);
            map.put("二进制",bytes);
            String base = Base64.getEncoder().encodeToString(bytes);
            System.out.println("base64"+base);
            map.put("base64",base);
            return map;
        }

    测试效果:

     

    可以看到返回的json数据中,base64位和二进制数据流返回的一样。猜测,mvc返回json会把二进制数据自动转换为base64位

    。数据库存二进制。BLOB,存储二进制大对象。

    前端使用base64位数据显示图片。
