这适用于某些URL,例如https://speed.hetzner.de/10GB.bin,它在我的Subscriber中输出了很多调试消息,所以我的控制台看起来像这样：

I got 16384 bytes (6396)
Got data!
I got 16384 bytes (6397)
Got data!
I got 16384 bytes (6398)
Got data!
I got 16384 bytes (6399)

和taskmanager说java正在下载~50Mbit / s(我的完全下载速度)

但是你可以在这里找到你可以下载的文件的网址https://map.usbcraft.net/file/usbpc-downloads/java_http_client.fail,这是非常不同的.控制台仅显示以下消息：

Starting download...

永远不会调用MySubscriber :: onNext.然而,taskmanager仍然显示我的文件以全速

编辑：
让它运行了很长一段时间之后它打印了更多内容(这是针对另一个URL但是对于我目前正在运行的更新的URL应该是相同的)：

因此,由于某些原因,java将内容长度解析为负数,它会将标题解析为Int,并导致整数溢出,但只有该URL,因为另一个文件的大小为10GB,但工作正常.

使用像wget或像Firefox这样的webbrowser之类的工具下载该文件没有问题.这对1fichier上的所有文件都不是问题,只是一些.

可以解释发生了什么事吗？
