lua zlib

ming.liu1123

Are you familiar with https://github.com/brimworks/lua-zlib

I used it as following

local zlib = require("zlib")

local inflate_stream = zlib.inflate()

local inflated_body = inflate_stream(rbody)

local reverted_rbody, _ = string.gsub(inflated_body, "AAA", "BBB")

local deflate_stream = zlib.deflate()

rbody = deflate_stream("reverted_rbody", 'full')

I want to unzip it, replace something, then zip it again.

But the re-compressed content got another format, that was not a gzip again

I can't gunzip the output, it said "not a gzip"

Any hint appreciate !

Just create a new issue on that github project page:

    https://github.com/brimworks/lua-zlib/issues

The author Brian Maher has been quite responsive AFAIK :)

And it's also a good idea to access the zlib C API directly from
within your Lua code by means of the LuaJIT FFI:
