Question

我已将图像存储为类型-image-在我的数据库（Sqlserver）中问题是当我尝试将其发送到android作为类型byte []我有内存错误因为我尝试尝试加载所有图像同时 ... 我在这里找到的解决方案之一是将图像作为链接发送，只有想象才需要它现在我想只获取php中的图像链接并将其发送到android 我不知道如何将图像（存储在DB中）转换为php中的链接并将其发送到android

你内存不足，因为你试图将所有图像都放在同一个文件中Json

试试这个解决方案：

 Glide.with(ctx)
             .load("http://192.168.1.8/connect/getimage.php")
              .into(holder.img);

脚本PHP ==＆gt; getimage.php

$sql="select img from table where id=1032 ";


    $stmt = sqlsrv_prepare( $this->connection, $sql);
    $result = sqlsrv_execute($stmt);

    $information = array();
    while($data = sqlsrv_fetch_array($stmt))
        {
            $img=$data['img'];
        }

        echo $img;
