不对不对，官网上传也是一次性获取所有地址。反倒是越改越错。如果是分批调用 /file/getUploadUrl 的话，请求 101~200 分片，返回从 190 开始。

成功复现 400 报错，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<Error>
  <Code>InvalidPartOrder</Code>
  <Message>fail to get previous part hash context</Message>

  <RequestId>xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx-dongguanx-zone1</RequestId>
  <HostId>xxxxxxxx-dongguanx-zone1-dongguan6</HostId>
</Error>

请求 101~200 分片，返回从 190 开始。

仔细看了下，是数组排序不对，匹配到错误的分片上传，肯定不正常。
