oss20190517 upload part api set header 'Content-Type' invalid

[nadirvishun]

the upload part api can't identify the file mime ,so need set the Content-Type in the api InitiateMultipartUpload，there are not ContentType method, so I used headerParam，but after uploaded ,the Content-Type not change, what the right way to change the Content-Type?

 InitiateMultipartUploadRequest initiateMultipartUploadRequest = InitiateMultipartUploadRequest.builder()
                    .bucket(bucket)
                    .key(ossKey)
                    .headerParam("Content-Type", FileTypeUtils.getContentType(file))//here
                    .build();

您好，可以根据您的需求来选择使用的SDK，OSS原生支持的com.aliyun.oss:aliyun-sdk-oss和升级版非异步的com.aliyun:oss-20190517都是不支持异步调用的，升级版非异步SDK对新手较友好，尤其是其他语言转过来的开发者，较容易上手。而升级版异步库，也就是本库，面向对象是高级开发者，是阿里云官方SDK团队和对象存储团队合作的库，虽然目前还有未完善的地方，但是会持续更新，后续会逐步完善。
