Java: Gzip string to output string

问题:

How do I take a string and use something like GZIPOutputStream to gzip the string and then output the zipped content as a string.

My intention is to transfer the zipped content as a post variable through HTTP.

回答1:

The steps are actually pretty simple:

• Use the GZIPOutputStream to write it to a ByteArrayOutputStream... close the GZIPOutputStream
• Call ByteArrayOutputStream.toBytes() to get the byte array
• Use a Base64 encoder on the result

The server will perform essentially the reverse of these operations.
