Modify the s_client code to NOT disconnect when end-of-input is reached
from stdin. Then, using this modified client, you can create a file
with the "GET /document.html HTTP/1.0<cr><ctr>" in it, and do a simple
redirection
$data = `openssl s_client -connect remote.com:443 <datafile`;
The problem with the existing s_client is that it shuts down as
soon as it detects EOF. When running interactively, that's fine.
But when running from command line, the connection is shut down
before the response ever has a chance of arriving.
The change in apps/s_client.c, look for
if ((!c_quiet) && ((i <= 0) || (cbuf[0] == 'Q')))
{
BIO_printf(bio_err,"DONE\n");
goto shut;
}
What we've done in the past is simply add a flag indicating that the
input stream is closed (e.g. STDIN_closed=true;),
Then, earlier on in the same file, where it sets the file descriptor
for the select, modify the "if (read_tty)" to be
"if (read_tty && !STDIN_closed)". Finally, make sure you initialize
STDIN_closed to false initially.
if (tty_on)
{
if (read_tty)
FD_SET(fileno(stdin),&readfds);
if (write_tty)
FD_SET(fileno(stdout),&writefds);
}
Hope this helps.
(Hope I didn't overlook an already existing capability. I'd feel pretty
dumb
if there was one that I missed!)
Cheers, Thomas
