我有一个需要在我的ruby应用程序中下载的图像URL列表（> 1000）。我为此使用open-uri。我知道它有缺陷，但是如果您必须支持http，https和ftp，这很方便。
通话本身就这么简单
file = open(url) # an https url
此后，文件由回形针处理。
问题是，即使一次又一次地使用相同的URL，调用也会不时以Zlib::DataError失败。有时可以下载它们，有时图像会引发错误。这是堆栈跟踪：

我还用wget下载了图像，以查看服务器是否发送了损坏的图像，但是很难调试：您不确定所有是否正常，因为服务器未在其中返回错误。这样运行，或者服务器一切正常，并且没有错误。
所以我不确定错误是由服务器，open-uri还是...引起的？
因此，为了更好地调试此问题，我想了解为什么ruby http这样做
inflate，并且如果我可以解决它，或者如果有人以前经历过类似的事情。
