具体使用流程参考：STS临时授权访问OSS
这里我列出我的代码，以备以后复制使用。

上面用到的OssTokenVO实体：
package com.jdcloud.provider.model.vo;
import lombok.Builder;
import lombok.Data;
/**
* 阿里OSS Token VO
*
* @author leigq
*/
@Data
@Builder
public class OssTokenVO {
private String region;
private String accessKeyId;
private String accessKeySecret;
private String securityToken;
private String bucket;
private String expiration;
}
用浏览器请求此接口，结果如下：
tips：每次请求数据都会发生变化。
前端代码
前端先请求上面的接口，获取到region、accessKeyId、accessKeySecret、stsToken，就可以上传图片了。
