怎么获取通过gzlib压缩的post数据

geyuanye

server ngx_openresty/1.2.8.5rc1

local ffi = require("ffi")

ngx.req.read_body()

local p_data = ngx.req.get_body_data()

ngx.say(p_data)

打出来是null

local p_args = ngx.req.get_post_args()

for key, val in pairs(p_args) do

ngx.say(key )

也打不出来。

不知道在哪一步去uncompress?

引用一下 ngx.req.get_body_data
的官方文档（http://wiki.nginx.org/HttpLuaModule#ngx.req.get_body_data ）中的说明：

“This function returns nil if

1. the request body has not been read,
2. the request body has been read into disk temporary files,
3. or the request body has zero size.

...

If the request body has been read into disk files, try calling the
ngx.req.get_body_file function instead.

To force in-memory request bodies, try setting client_body_buffer_size
to the same size value in client_max_body_size.
”

Thanks.  ngx.req.get_body_file 我也试了。后来发现是同事用的gzip库有问题。
