进入https://help.aliyun.com/document_detail/155645.html?spm=api-workbench…0.0.33171e0fRQiZ2X
利用oss存储图片并转换为URL形式

上传我们的文件

复制图片URL链接

采用如下代码获取URL

from viapi.fileutils import FileUtils
file_utils = FileUtils("LTAI5t8DuJ5bKttW4QkM3Rh9","a6EHULocaiqmbvXjrjBqOL16zhjpq9")
oss_url = file_utils.get_oss_url('https://otstest.oss-cn-beijing.aliyuncs.com/train/0_Anger/1.jpg?Expires=1636356165&OSSAccessKeyId=TMP.3KjPYnBNhd32RkJLqnMooNkMVqzvbbmdNsPPrsDnvCz8dmXaK3HARk3nukYE5SUSXCSK1wxhhez8WvehUy5YGPutHQNbL9&Signature=5f5m4gbW41JEjKGn4f4YyIgDxkM%3D&versionId=CAEQFRiBgICyuI6T5xciIDQyM2Q3MjIxZDJhYzRlNjg4NTI0ZTc0YTk3NDk1ZDIw&response-content-type=application%2Foctet-stream',"jpg",False)
print(oss_url)

调用结果

接下来我们利用代码获取URL
