这里附一张图，解释 endpoint 跟 bucketName 一看就明白了

然后再activity foresult 调用

//这里的选择图片是个框架，你可以使用自己习惯用的

// objectKey 这个是我们规定的图片名字规则

List<LocalMedia> selectList = PictureSelector.obtainMultipleResult(data);
if (selectList.size() > 0) {
    LocalMedia localMedia = selectList.get(0);
    String path1 = localMedia.getPath();
    File file = new File(path1);
    String name = file.getName();
    Glide.with(this).load(path1).into(ivId);
    String objectKey = "此处就不显示了，文件目录" + "/" +
            UserManager.getInstance().getUserInfo().getId() +
            UUID.randomUUID().toString().replace("-", "")+"_front_" + name;
    OssManager.getInstance().init(this, Constants.TEST, accessKeyId, accessKeySecret, securityToken);
    OssManager.getInstance().upload(objectKey,path1);
    String imageUrl = OssManager.getImageUrl();
    if (!StringUtils.isEmpty(imageUrl)){
        photo1 = baseUrl+imageUrl;
    }else {
        ToastUtils.showShort("上传失败，请重新上传");
    }
}
