Hmm, think he's talking about evhtp, not evhttp.
The evhtp_request_t structure contains the evhtp_uri_t structure which
tries to maintain the proper tree-format of a URI:
uri ->
authority ->
username
password
hostname
port
path ->
full path (/a/b/c.html)
path (/a/b/)
file (index.html)
fragment ->
data after '#' in the query
scheme ->
the scheme of the request if found
query ->
a evhtp_kv_t list of query keys and values
You can get the raw query arguments by using
request->uri->query_raw
or you can access the parsed query arguments via this:
request->uri->query
by either looking for specific values:
const char * val = evhtp_kv_find(request->uri->query, "key");
Or by iterating over each one:
int my_callback(evhtp_kv_t * kv, void * arg) {
printf("key=%s val=%s\n", kv->key, kv->val);
return 0;
}
evhtp_kvs_for_each(request->uri->query, my_callback, NULL);
