问题描述

如何在Python中将流的内容传输到另一个?

How do I transfer the contents of a stream to another in Python?

琐碎的解决方案是

output.write(input.read())

但如果输入文件大于可用内存(甚至无限大),则会失败;当部分副本也有用时,它也不能正常工作。基本上我正在寻找相当于。

but that fails if the input file is larger than the available memory (or even infinitely large); and it doesn't work well when a partial copy is useful as well. Basically I'm looking for the equivalent of org.apache.commons.IOUtils.copy.

推荐答案

shutil.copyfile shutil.copyfileobj 用于救援。请参见

shutil.copyfile and shutil.copyfileobj for the rescue. See http://docs.python.org/library/shutil.html#module-shutil
