How should I ungzip a string?

推荐答案

上述方法对我不起作用.
我一直收到incorrect header check (Zlib::DataError)错误.显然，它假定默认情况下您具有标头，但情况并非总是如此.

The above method didn't work for me.
I kept getting incorrect header check (Zlib::DataError) error. Apparently it assumes you have a header by default, which may not always be the case.

我实施的解决方法是:

require 'zlib'
require 'stringio'
gz = Zlib::GzipReader.new(StringIO.new(resp.body.to_s))    
uncompressed_string = gz.read
