Bash script to enter a web page

Question

I try to enter this page , but I can’t get it to work for life. I need to log in to this site when I connect to my school Wi-Fi to start a session.

So far, ive has tried to use bash and cUrl to achieve this, but has only reached to give herself a headache. will cUrl work or am I mistaken? Any help is much appreciated!

Thanks,

N

Here is what I tried:

curl --cookie-jar cjar --output /dev/null http://campus.fsu.edu/webapps/login/ curl --cookie cjar --cookie-jar cjar \ --data 'username=foo' \ --data 'password=bar' \ --data 'service=http://campus.fsu.edu/webapps/login/' \ --data 'loginurl=http://campus.fsu.edu/webapps/login/bb_bb60/logincas.jsp' \ --location \ --output ~/loginresult.html \ http://campus.fsu.edu/webapps/login/ 

Answer 1

Some things that you are clearly mistaken, your form is as follows:

 <form onsubmit="return validate_form(this)" method="post" action="https://bb5.fsu.edu/cas/" id="login" AUTOCOMPLETE="off"> <!-- etc --> </form> 

You need to send a request to the action form URL, and you need to make a POST request instead of a GET request to a different URL.

Answer 2

 curl -c vh.cookie "http://campus.fsu.edu/webapps/login/bb_bb60/logincas.jsp?username=foor&password=bar" curl -b vh.cookie "http://campus.fsu.edu/webapps/login/login.result" 

where http://campus.fsu.edu/webapps/login/login.result is the final URL after user authentication

so first authenticate, then call curl again and load the cookie into the authenticated URL

I managed to do this with python and mechanize. Should work for you too:

You can also download the selenium plugin and export the login script as a python, ruby ​​or java script. With some loaded libraries you will achieve the same.
