Remember the old days when you would add a contact form to your homepage with something like the following code?
<FORM METHOD ="post" ACTION="/cgi-bin/mail-a-form">
<P>Van (e-mailadres): <INPUT TYPE="text" NAME="from"><BR>
<INPUT TYPE="hidden" NAME="subject" VALUE="Formulier verstuurd vanaf paginanaam">
<INPUT TYPE="hidden" NAME="missing" VALUE="http://loginnaam.home.xs4all.nl/">
<INPUT TYPE="hidden" NAME="nextpage" VALUE="http://loginnaam.home.xs4all.nl/">
<INPUT TYPE="hidden" NAME="to" VALUE="[email protected]">
<TEXTAREA NAME="veld3" ROWS="5" COLS="40">Dit is een veld waarin veel tekst kan worden ingevuld</TEXTAREA><BR>
<INPUT TYPE="submit" VALUE="Verstuur">
<INPUT TYPE="reset" VALUE="Wis">
</FORM>
Well, first of all, these days aren't as you might think! This HTML sample code can still be viewed in 2021 at https://www.xs4all.nl/service/diensten/hosting-en-homepage/gebruiken/shared-webhosting/cgi-scripts/mailaform.htm
Inquire does more or less the same thing as mail-a-form above,
except that it doesn't let the caller define the "To" address for
obvious reasons. If you want to change the "To" address you'll have to
edit the source code and recompile with go build. You can embed a
contact form like this:
<form action="https://inquire.rtts.eu/" method="post">
<input type="email" name="email">
<input type="hidden" name="redirect" value="https://rtts.eu">
<input type="hidden" name="subject" value="Contact Form">
<textarea name="message"></textarea>
<button>Send</button>
</form>
(Note: some not-so-advanced spam protection has been added so the above example will not work anymore. Check out the source code!)
This couldn't be easier! Just copy the binary anywhere you'd like and run it. The server wil listen on port 8008 and log to standard output. Of course, you should use some kind of process monitor like systemd in production environments. Here's a sample systemd service file:
[Unit]
Description = Inquire
[Service]
ExecStart = /opt/inquire/inquire
User = www-data
Restart = always
[Install]
WantedBy = multi-user.target
Also, here's an example configuration to use nginx as a reverse proxy:
server {
server_name inquire.rtts.eu;
listen 80;
listen 443 ssl;
ssl_certificate inquire.rtts.eu.chained.crt;
ssl_certificate_key inquire.rtts.eu.pem;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://127.0.0.1:8008;
}
location /.well-known/acme-challenge {
alias /etc/nginx/challenges/inquire.rtts.eu;
}
}
