[Patch]Parsing CGI Vars in HTTP POST method in HTTP SMSC

[sangprabv]

Hi,
I just tried to modify and copied an existing function (Octstr
*http_get_header_parameter(Octstr *value, Octstr *parameter);) to a new
function (Octstr *http_cgipost_variable(Octstr *value, Octstr
*parameter);) to parse CGI Vars (var1=value1&var2=value2) in POST method
in HTTP SMSC. It still don't work. I need some hand to check it out.
TIA.

Octstr *http_cgipost_variable(Octstr *value, Octstr *parameter)
{
        long pos, c, len, end;
    int found = 0;
    Octstr *result = NULL;
   
   len = octstr_len(value);
   
   for (pos = 0; pos < len; pos++) {
        c = octstr_get_char(value, pos);
        if (c == '&')
            break;
    }

    if (pos >= len)
        return NULL; 
      
        for (pos++; pos > 0 && pos < len && found == 0; pos++) {
        Octstr *key = NULL;
      Octstr *val = NULL;
        
        end = octstr_search_char(value, '=', pos);
        if (end < 0)
                end = octstr_search_char(value, '&', pos);
        if (end < 0)
                end = octstr_len(value);
        key = octstr_copy(value, pos, end - pos);
        octstr_strip_blanks(key);
        pos = end;
        
        if (octstr_get_char(value, pos) == '=') {
            pos++;
            while (isspace(octstr_get_char(value, pos)))
                pos++;
                end = octstr_search_char(value, '&', pos);
            if (end < 0)
                end = octstr_len(value);
            val = octstr_copy(value, pos, end - pos);
            octstr_strip_blanks(val);
            pos = end;
            pos = octstr_search_char(value, '&', pos);
        }

        if (octstr_case_compare(key, parameter) == 0) {
            found++;        
            result = octstr_duplicate(val);
        }

        octstr_destroy(key);
        octstr_destroy(val);
   }
   return result;
}

called with:
static void telco_receive_sms(SMSCConn *conn, HTTPClient *client,
                               List *headers, Octstr *body, List *cgivars)
{
tmp = octstr_duplicate(body);
text = http_cgipost_variable(tmp, octstr_imm("text"));
...
}
