A request body is available as a series of
buffers in r->request_body->bufs. To understand more about
buffers, try reading Evan Miller's guide as available from here:

http://www.evanmiller.org/nginx-modules-guide.html

Some example code which uses r->request_body->bufs to access
request body contents as available in memory can be found in
src/http/ngx_http_variables.c, in the
ngx_http_variable_request_body() function.

Note though, that depending on a configuration and a request, the
request body may not be available in memory at all (that is, it
will be in temporary file, and there will be a file buffer in
r->request_body->bufs).
