拼接data URL 每个步骤的详细操作如下所示: <details> <summary>步骤 1: 加载图片</summary> Filefile=newFile("path/to/image.png");BufferedImagebufferedImage=ImageIO.read(file); 1. 2. </details> <details> <summary>步骤 2: 获取字节数组</sum
可以使用以下代码: // 引用形式的描述信息StringimageUrl="data:image/jpg;base64,"+base64Image;System.out.println("Image URL: "+imageUrl); 1. 2. 3. 三、序列图 下面是一个简单的序列图,展示了整个流程的交互过程: ServerClientServerClient请求转换本地图片为URL读取本地图片文件将图片文件转换为Base64...

就是从一个网络读取图片并转成base64.发现转出来的结果无法用于img标签显示(已加了data:image/jpeg;base64,前缀)。后来直接百度找了一个在线生成base64的网站,把这个图片url放上去转换,结果发现别人在线转换出来的base64比我java代码转换的base64还长了很多。 为什么会这样呢?慕勒...
