Thanks for the help. From the command line, I did this:
curl -F uri='' -F username=ubnt -F password=ubnt
https://192.168.135.22/login.cgi -k --trace-ascii logfile.txt --cookie-jar
cookies.txt --location
The uri always seems to be empty when I check it with httpfox. The terminal
prints:

<body>

The logfile.txt contains:

You want -F and let curl handle the boundary string by itself:
curl -F uri=moo -F username=foobar -F password=secret
https://192.168.135.22/login.cgi -k
Add "--trace-ascii logfile.txt" to the command line to save the entire
request and verify that it actually looks like you want it to look.
Then you *probably* want to add "--cookie-jar cookies.txt" to the command
line as well to save cookies from the response, as that is probably how it
saves the logged in session. You then use "--cookie cookies.txt" in
subsequent requests to reuse that session (you probably want to use both
options since subsequent reqests might updated the cookies as well).
Finally, when you post the login data the server often redirects you to a
new page and curl doesn't following redirects by default. Use --location
for that.
(and avoid -X POST, that will only cause you grief)
