java - 如何在jsonobject中存储图像

Question

我想将图像放入 jsonobject 中，因此使用 (base64-encodetostring) 将其转换为字符串，但由于 base64 encodetostring 标志或 idk 的原因，我不会认为我尝试了多种方法来解决该问题，但在互联网上没有任何帮助，也没有解决方案。

我已经尝试过 base64.DEFAULT 标志和任何单个标志都没有任何帮助，因为我认为这是因为 base64.encodetostring 没有设置字符串的结尾或 idk 到底是什么

                pdp.compress(Bitmap.CompressFormat.JPEG,100,bytes);

                byte[] bytes1=bytes.toByteArray();

                Pdp= Base64.encodeToString(bytes1,Base64.NO_WRAP|Base64.URL_SAFE);

我将确切的 Pdp 字符串放入 jsono

                query.put("new_pdp",",pdp=cast('"+pdp+"==' as varbinary(max))");
            }else query.put("new_pdp","");

我将它记录到控制台，这是唯一编码字节的结果：

Base64 的解码和编码可能会占用大量内存。如果图像在服务器上，只需抓取 url 并查询它。
