            log.error("创建阿里云 OSS 临时token异常", e);
        }
        return null;
    }
}

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。
