Automated login using commandling in ubunto

[lhg1]

Hi

I would like to use an script to automaticly login to a webpage, and retrive the webpage to a txt file.

I tryed to get it to work using curl

curl --user name:password [URL unfurl="true"]http://www.url.com[/URL] -v >> webpage.log

But this does not work, the page is buield in asp and has a form with the login and Password.

I have been trying to read about how to save a login and password, maybi just the cookie, but haven't found anything that helps yet.

Regards
Lhg

Hi

Your code will work if the site uses HTTP authentication. If the username and password has to be entered in a HTML [tt]form[/tt], most probably there is no HTTP authentication behind it. ( No idea whether is possible in ASP. )

Probably you will have to make two requests with [tt]curl[/tt] : first to send the [tt]form[/tt] data for authentication, then to download the page. And most important, you have to make sure the 2^nd requests sends back the cookies received on the 1^st request.

By the way, I used to do such things with twill. Take a look, is not too complicated.

Hi

I just curl the page and this seems to be the password box.

twill seems like a good idea, I have a littel problem transfering the eksampel to my retrived code.

setlocal username <your username>
setlocal password <your password>

go [URL unfurl="true"]http://www.slashdot.org/[/URL]
formvalue 1 unickname $username
formvalue 1 upasswd $password
submit

code 200     # make sure form submission is correct!

do I use the ID for the formvalue
id="ctl00_mnuLeft1_mSignin_mnuSignin_Username"
id="ctl00_mnuLeft1_mSignin_mnuSignin_Password"

Hi

Well, I always used [tt]name[/tt]s in twill commands. Fortunately those [tt]input[/tt]s have [tt]name[/tt] attributes, so use those. Something like this :

[b]formvalue[/b] 1 "ctl00$mnuLeft1$mSignin$mnuSignin$Username" [i]your_username_here[/i]
[b]formvalue[/b] 1 "ctl00$mnuLeft1$mSignin$mnuSignin$Password" [i]your_password_here[/i]
[b]submit[/b]

Of course, this will not work if :
[ul]
[li]There are other [tt]form[/tt]s in the page before this one ( for example a search form in the page header, like we have here on Tek-Tips too ). Then you will have to adjust those 1 to match the login [tt]form[/tt]'s order number.[/li]
[li]The [tt]form[/tt] tag's [tt]action[/tt] attribute is empty or has a dummy value. Then you have to find out where the [tt]form[/tt] is actually sent and tell it to twill with [tt]formaction 1 real_url_here[/tt] before calling [tt]submit[/tt].[/li]
[/ul]

I'm having trouble getting this to work.

I tryed to change the formvalue but still I only get this message in twill-sh

Oops! Twill assertion error on line 1 of 'kandu.twill' while executing

>> formvalue 1 "ctl00$mnuLeft1$mSignin$mnuSignin$Username" l1977

no matching forms!

** UNHANDLED EXCEPTION: no matching forms!

this is the page I am trying to create a autologin script for.
kandu.dk

I'm not sure what you ment by the secound "will not work if"

Thanks

Hi

Seems they have a "clever" firewall. By default [tt]twill[/tt] sends no [tt]User-Agent[/tt] HTTP request header and that triggers the firewall's suspicion. So it sends back an error page with no [tt]form[/tt]. Probably that is why you get that strange error message.

Add this somewhere before the [tt]go[/tt] command in your [tt]twill[/tt] script :

[b]agent[/b] "Mozilla/5.0 (Windows NT 6.1; rv:26.0) Gecko/20100101 Firefox/26.0"

Hi

Thanks, it allowed a bit more progress

I changed the login names to

formvalue 1 "ctl00_mnuLeft1_mSignin_mnuSignin_Username" L1977
formvalue 1 "ctl00_mnuLeft1_mSignin_mnuSignin_Password" larshg

But it is still not working, even thou I am not getting an error anymore

twill-sh kandu.twill3
>> EXECUTING FILE kandu.twill3
AT LINE: kandu.twill3:0
AT LINE: kandu.twill3:2

Note: submit is using submit button: name="ctl00$mnuLeft1$mSignin$mnuSignin$loginButton", value=""

AT LINE: kandu.twill3:7

Hi

Ouch. There is a syntax error in the page's code : the password [tt]input[/tt] has two [tt]name[/tt] attributes. The browsers use and the server expects the 1^st one, but the [tt]twill[/tt] version I use handles the 2^nd one.

However is strange that your [tt]twill[/tt] not yelled for that. Maybe your version is better than mine, so try to continue.

Add this after the [tt]submit[/tt] command :

[b]code[/b] 200
[b]save_html[/b] [i]output_file_name.html[/i]

Then run the script and check the resulted output file.

Hi

I installed twill on an ubunto linux like this.

sudo apt-get install python-twill

In the HTML file I can se that the username is added, I cant se the code, I'm not sure if that is if its hidden, or if it didn't work.
And I seem not to have made the Login button

This is an image of the html page.

My current script

agent "Mozilla/5.0 (Windows NT 6.1; rv:26.0) Gecko/20100101 Firefox/26.0"

go [URL unfurl="true"]http://kandu.dk/[/URL]
formvalue 1 "ctl00_mnuLeft1_mSignin_mnuSignin_Username" L1977
formvalue 1 "ctl00_mnuLeft1_mSignin_mnuSignin_Password" larshg
submit

code 200     # make sure form submission is correct

save_html kandu3.html

I can't really figure out how to activate the login
