实现
1、设计流程
2、第一个流程/image路由使用read file节点读取和显示文件
编辑read file节点
3、编辑http response节点，响应头为image/png
4、部署之后，访问
http://127.0.0.1:1880/image
5、第二个流程主要编辑template节点中HTML中建立访问图片的img标签，src属性就是对应上面第一个流程的
/image路由
<html>
<head>
<title>显示图片</title>
</head>
<body>
<h1>霸道的程序猿</h1>
<img src="/image" height="200" weight="200"/>
</body>
</html>
6、部署后访问
http://127.0.0.1:1880/show
7、流程json数据
