string io api
gzip api
我們想要壓縮一下sting, 可以用
<br /> #因為GzipWriter should be used with an instance of IO, or IO-like, object.<br /> #所以我們弄個StringIO來玩<br /> output = StringIO.new<br /> gz = Zlib::GzipWriter.new(output)<br /><br /> gz.write 'blahblah'<br /> gz.close<br /><br /> output.string #便是我們要的壓縮過後的string<br /><br /><br /> output = StringIO.new<br /> gz = Zlib::GzipWriter.new(output)<br /> gz.write(t.to_json)<br /> gz.close<br /> render :text => output.string, :content_type => 'application/x-gzip' and return<br /><br />
