RDB1868Cmsis2_uip webserver - cgi function problem

ronwal — Thu, 19 Jan 2017 10:15:33 GMT

Hello

My project is based the RDB1868Cmsis2_uip webserver sample. Hardware is OM130085.

When defining cgi functions in my html page, the page will be created faulty by the webserver

This happens, even if the function doesn´t exist on the the controller,

Let´s say:

I define an input control with "!% name" as value, in order to be updated by the controller.

<input name="Text1" type="text" value="%! name"/></form>

</p>

<script>
function myFunction() {

a.s.o

After starting the webserver and loading that page the input control looks like this:

If i than analyze the html page (with F12 inside IE) I can see that the page have been sent faulty by the webserver:

<p><input name="Text1" type="text" value=" </p>

I am pretty sure, that I didn´t change anything related of the original code.

Does anybody have the same problem or any idea how to solve?

Thanks in advance.

I found the cause myself.

Just in case someone facing the same problem:

For a script end we are looking for a new line in the following function:

static void
next_scriptstate(struct httpd_state *s)
{
char *p;
p = strchr(s->scriptptr, ISO_nl) + 1;

That´s why in case of an input box we have to write the html code like this and it´ll work!

<form method="post">
<input name="Text1" type="text" value="
%! shuttlespeed
"/></form>
