6. Can you fix it by yourself and request PR, if not, what's problem do you get when you try to fix it

* debug跟踪了一下代码

有以下发现，在分块下载部分，给服务器传的Range无效，服务器还是返回自己的Range。
这一点我在Postman上测试了一下，确实如此。
![6](https://user-images.githubusercontent.com/9621271/46868930-ad316580-ce19-11e8-9894-a96374c33316.jpg)

然后，我使用UC浏览器和QQ浏览器都能正常下载。我用Fiddler抓包试了下，看了下他们的分块。

* UC浏览器分块：
![8](https://user-images.githubusercontent.com/9621271/46869338-ed451800-ce1a-11e8-91bb-6925197072fd.jpg)

* QQ浏览器分块：
![9](https://user-images.githubusercontent.com/9621271/46869340-f0d89f00-ce1a-11e8-8ae8-4d6482bfbc6f.jpg)

发现他们刚开始都发了一个Range: bytes=0- 的请求。而且都有5242880这个块。
![10](https://user-images.githubusercontent.com/9621271/46870124-4dd55480-ce1d-11e8-87d8-807f182f5cbe.jpg)

我猜测他们自己也提前分好块了，然后请求服务器得到的分块和自己的分块数据不一致，优先又服务器的分块，然后对自己剩下的块再分配，然后再请求服务器验证分块是不是一致，如果不一致，就用服务器的分块。不知道我的猜测正不正确。

所以请教一下怎么能解决这个下载的问题~ 谢谢！
