Reading post parameters from apache request
Hi,
I am trying to write a custom module where I need to read post parameters
from the request. I guess apreq library is relevant to this but could not
find any substantial examples or documents.
Is there any other way to read the params other than apreq. Any pseudocode/
examples will be appreciated.
Thanks,
Pranil

Sorin, Yoichi,
Thanks for your responses. The below code worked for me using apreq.
const apr_table_t* args;
apreq_handle_t* h = apreq_handle_apache2(r);
apreq_body(h, &args);
const char *params = apreq_params_as_string(r->pool, args, NULL,
APREQ_JOIN_QUOTE);

Hi
I have an another example. I read post parameters in the source code below:
http://github.com/yokawasa/mod_akismet/blob/master/mod_akismet.c#L647
line: 647 - 705
hope this helps you.

Here you have an example. It is not optimal, you could, for example,
take the brigade creation out of the loop and clean the brigade at the
end of each iteration, after you extracted the data.
apr_bucket_brigade *bb;
do {
bb = apr_brigade_create(req->pool, req->connection->bucket_alloc);
if (0 == bb)
// error
if (APR_SUCCESS != ap_get_brigade(req->input_filters, bb,
AP_MODE_READBYTES, APR_BLOCK_READ, 9216))
// error
extract data from bb;
} while (EOS not yet encountered in bb);
