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。

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：

* QQ浏览器分块：

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。

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！
