Edge瀏覽器圖形驗證碼無法正常顯示

其他瀏覽器顯示正常。

			//生成驗證碼文本
            String capText = captchaProducer.createText();
            logger.info("[{}]生成驗證碼文本===={}",mobile,capText);
            //利用生成的字符串構建圖片
            BufferedImage bi = captchaProducer.createImage(capText);
            ServletOutputStream out = response.getOutputStream();
            ImageIO.write(bi, "jpg", out);
            try {
                out.flush();
            } finally {
                out.close();
            }

io流的形式將圖片傳到前端用img接收，在Edge瀏覽器顯示

<img src="/resource/images/pic_login_code.jpg" onclick="getCaptcha();" width="80" height="32"> 

修改處理方案：

			//生成驗證碼文本
            String capText = captchaProducer.createText();
            logger.info("[{}]生成驗證碼文本===={}",mobile,capText);
            //利用生成的字符串構建圖片
            BufferedImage bi = captchaProducer.createImage(capText);
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            ImageIO.write(bi, "png", out);
            String result = Constants.IMG_BASE64_PREFIX + Base64.getEncoder().encodeToString(out.toByteArray());

後端將圖片流用Base64加密生成字符串，在前端用img src接收，然後問題解決
