responding to form login fields
Hi all,
After tons of look up - I haven't been able to find a good example of
being able
to correctly respond to a login form that is using an type="image" to
initiate the login
process. The fields in the html are:
<td>
Username:<br>
<input
type="text" size="30" maxlength="60" name="username"><br>
Password:<br>
<input
type="password" size="30" maxlength="60" name="pwd">
<input
type="image" src="images/buttons/submit_gray.gif
<view-source:http://www.gomeznetworks.com/images/buttons/submit_gray.gif
> " name="login" align="absmiddle">
<input
type="hidden" name="server_string" value="">
<input
type="hidden" name="url_string" value="">
<input
type="hidden" name="query_string" value="">
<input
type="hidden" name="form_string" value="">
</td>
and I need to respond to username, password and login. I do not
understand how to create the NameValuePair to respond to the
image in order to submit the login and move to the next page in the
sequence.
Any thoughts, hints ?
Thanks,
Jim

Hi Jim,
The type="image" attribute for a form just creates a visual element
that, when clicked on, triggers the form action.
The snippet of HTML below doesn't include the outer <form> element, or
more importantly its action="xxx" attribute, but that's what you want
to look for.

Pretty simple, I did have an entity/response pair that did a GET, which
is why you see a response2/entity2, it returned the page, but I removed
that
code to get it down to just this.
Jim
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new
HttpPost("http://www.gomeznetworks.com/login.asp");
List<NameValuePair> vals = new ArrayList<NameValuePair>();
vals.add(new BasicNameValuePair("username", "****"));
vals.add(new BasicNameValuePair("pwd", "****"));
post.setEntity(new UrlEncodedFormEntity(vals, HTTP.UTF_8));
HttpResponse response2 = client.execute(post);
HttpEntity entity2 = response2.getEntity() ;
System.out.println("Login form get: " +
response2.getStatusLine());
System.out.println("Response content length: "
+ entity2.getContentLength());
if (entity2 != null) {
System.out.println(EntityUtils.toString(entity2));
entity2.consumeContent();
client.getConnectionManager().shutdown() ;

Hi Jim
How do you create your HttpClient? I once had a similar problem with
trying to log into a server and kept being returned to the login page
- it was solved by reusing the same httpClient for all subsequent
requests of the same user session. (I must admit that I still don't
know exactly why this worked - but it did)

Hi Ernst, thanks, good tip w/ firebug - resolved the issue by supplying
values
for login.x and login.y.

One thing you can try is logging in with a purposefully incorrect
username/password combo an check your response. This should give you
the login page but with an error message:
UserName and/or Password you entered are incorrect. Please update them
below.
If this is not the case, then the post is not handled correctly. I
suspect that the javascript that actually submits the form does
something with all those hidden fields before submission - otherwise
they are quite meaningless.
You could also try some browser plugin like liver http headers or
firebug (both for firefox) to see what is posted or you can
investigate the javascript that actually does the submit to see what
it does to all the hidden form fields.

RE: responding to form login fields
Posted by "Langston, James" <Ja...@compuware.com>.
Thanks Ernst,
Already on that tangent, incorrect password, in the browser will produce
some invalid user/pwd text and give the text fields again. Nothing like
that
text comes back via httpclient submission with bogus user/pwd. I've also
wandered
over to curl which generates the exact same thing. So, I'm figuring
something
else is amiss
Jim

Re: responding to form login fields
Posted by Ernst Nolte <er...@synquad.nl>.
Hi Jim
One thing you can try is logging in with a purposefully incorrect
username/password combo an check your response. This should give you
the login page but with an error message:
UserName and/or Password you entered are incorrect. Please update them
below.
If this is not the case, then the post is not handled correctly. I
suspect that the javascript that actually submits the form does
something with all those hidden fields before submission - otherwise
they are quite meaningless.
You could also try some browser plugin like liver http headers or
firebug (both for firefox) to see what is posted or you can
investigate the javascript that actually does the submit to see what
it does to all the hidden form fields.
Met Vriendelijke groet/Kind regards,
Ernst Nolte

RE: responding to form login fields
Posted by "Langston, James" <Ja...@compuware.com>.
Hi Ernst,
Ok - digging at this a little more, it looks like this is the string
needed for
submitting.
file:///home/jim/Desktop/login.asp?username=****&pwd=****&login.x=&login
.y=&server_string=&url_string=&query_string=&form_string=
I have change my code to reflect those parameters:
List<NameValuePair> vals = new ArrayList<NameValuePair>();
vals.add(new BasicNameValuePair("username", "****"));
vals.add(new BasicNameValuePair("pwd", "****"));
vals.add(new BasicNameValuePair("login.x", ""));
vals.add(new BasicNameValuePair("login.y", ""));
vals.add(new BasicNameValuePair("server_string", ""));
vals.add(new BasicNameValuePair("url_string", ""));
vals.add(new BasicNameValuePair("query_string", ""));
vals.add(new BasicNameValuePair("form_string", ""));
but, the results are the same, any thoughts ?

That was what I thought so I set all cookies manually, but with no

Because along with the HttpClient instance you also kept all cookies
stored in the cookie store associated with that instance.

Hi Jim
How do you create your HttpClient? I once had a similar problem with
trying to log into a server and kept being returned to the login page
- it was solved by reusing the same httpClient for all subsequent
requests of the same user session. (I must admit that I still don't
know exactly why this worked - but it did)

RE: responding to form login fields
Posted by "Langston, James" <Ja...@compuware.com>.
Hi Ernst,
After a couple of starts and stops. Yes, using 4.0.1 and
also tried 4.1alpha1 , after doing the post, w/ a username
and password, I do not see the next page, the response shows
just the initial page which has the login/passwords field, but
not the next page which is what I'm expecting to see.
any thoughts ? seems that I'm not posting the login/password.
Jim
HttpPost post = new
HttpPost("http://www.gomeznetworks.com/login.asp");
List<NameValuePair> vals = new ArrayList<NameValuePair>();
vals.add(new BasicNameValuePair("username", "****"));
vals.add(new BasicNameValuePair("pwd", "****"));
post.setEntity(new UrlEncodedFormEntity(vals, HTTP.UTF_8));
HttpResponse response2 = client.execute(post);
HttpEntity entity2 = response2.getEntity() ;
System.out.println("Login form get: " +
response2.getStatusLine());
System.out.println("Response content length: "
+ entity2.getContentLength());
if (entity2 != null) {
System.out.println(EntityUtils.toString(entity2));
entity2.consumeContent();
}

Hi Jim
I assume you use HttpClient v4?
If you look at the form action attribute in the page you will see this:
<form action="login.asp" method="post" id="form1" name="form1">
So you need to post the parameters to this url:
http://www.gomeznetworks.com/login.asp
and set the fields like this:
HttpPost post = new HttpPost(url);
List<NameValuePair> vals = new ArrayList<NameValuePair>();
vals.add(new BasicNameValuePair("username", "you"));
vals.add(new BasicNameValuePair("pwd", "passwd"));
post.setEntity(new UrlEncodedFormEntity(vals, HTTP.UTF_8));
and now execute it.
as far as the input type image is concerned, I think the onclick event
of image is captured bij Javascript event attachment and in that
handler the form is posted, but I did not bother to verify that.
