建立 QiNiuYunConfig

建立QiNiuYunController

添加upload.html
<!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta http-equiv="Content-Type" content="multipart/form-data; charset=utf-8" /> <meta charset="UTF-8"> <title>上传文件</title> </head> <body> <form action="/qiniu" method="post" enctype="multipart/form-data"> <label>上传图片</label> <input type="file" name="file"/> <input type="submit" value="上传"/> <p>回显图片:</p> <img th:src="${link}"/> </form> </body> </html>
运行
输入 http://localhost:8080/test
