+# UI 开发流程
+当点击中间upload an image as the base for generation 区域的时候，调用手机相册功能选择一张图片，一次只允许一张。用户选完图片后图片显示在 upload an image as the base for generation区域，并隐藏提示信息。
+当点击Generate Video的时候如果用户没有选择图片择提示用户选择图片，如果已经选择了图片则开始按下面的步骤调用接口
+# 接口调用
+## 第一步
+通过/v1/image/upload-presigned-url接口获取文件上传地址，通常是uploadUrl1或者uploadUrl2,以及对应的filePath1和filePath2用于生成视频接口的入参
+## 第二步
+通过上一个接口获取的upload url 用put协议将图片上传到对应的地址，注意：图片上传不需要经过代理 并且需要将requiredHeaders的参数全部设置到请求头中
+## 第三步
+调用/v1/image/create-task接口并传入filePath1或者filePath2传入到srcImg1Url或者srcImg2Url
