Hi All,
I have been trying to log into a website for the past few days but with
no luck using HTTPClient. I will now post all my findings so hopefully
someone can spot my mistakes. The form on the site has this code:
<form onsubmit="return ValidateForm(this)" method="post"
action="?iCmsPageId=32&sAction=CheckLogin">
<p>Username</span>
<input type="text" id="sUsername" name="sUsername" value=""
maxlength="50" style="width: 200px;" /></p>
<p>Password</span> <br />
<input type="password" id="sPassword" name="sPassword" value=""
maxlength="50" style="width: 200px;" /></p>
<script language="JavaScript" type="text/javascript">
<!--
function ValidateForm(oForm)
{
var sError = '';
if(!Empty(sError))
{
alert(sError);
return false;
}
return true;
}
-->
</script>
<div class="button" >
<div class="buttonimg">
<img border="0" alt="" src="img/btn_box_arrow.jpg"/>
</div>
<div class="buttontext">
<input class="textsubmit" type="submit"
onmouseout="changeTextDecoration(this,'none');"
onmouseover="changeTextDecoration(this,'underline');" style="color:
rgb(226, 0, 110); text-decoration: none;height:16px;" value="Login"/>
</div>
</div>
so therefore i coded the following where LOGON_PAGE is the actual page
where login occurs rather than the root page :
PostMethod authpost = new PostMethod(LOGON_PAGE
+"?iCmsPageId=32&sAction=CheckLogin");
authpost.setDoAuthentication(true);
NameValuePair action = new NameValuePair("action",
"?iCmsPageId=32&sAction=CheckLogin");
NameValuePair username = new NameValuePair("sUsername", "username");
NameValuePair password = new NameValuePair("sPassword", "password");
authpost.setRequestBody( new NameValuePair[] {action, username,
password});
System.out.println("Login form post status: " +
authpost.getStatusLine().toString());
//System.out.println("Page Content: " +
authpost.getResponseBodyAsString());
System.out.println("Path: " + authpost.getPath());
System.out.println("Redirection: " +
authpost.getFollowRedirects());
System.out.println("Location: " +
authpost.getResponseHeader("location"));
Header[] responseHeaders = authpost.getResponseHeaders();
for (int i=0; i<responseHeaders.length; i++){
System.out.print(responseHeaders[i]);
}
System.out.println("Login Status Text: " +
authpost.getStatusText());
and the output on the console was the following at the very bottom . It
seems from the result of authpost.getStatusText() being 200 that it
posted ok but I know from tests with my browser that I should get
another cookie when I log in (even though it is deleted after log out)
but I never get that final cookie so it looks like the login has failed
and I also looked at the result returned from getResponseBodyAsString()
and its still the initial login page. Actually, even when I changed the
username or password to something wrong it still returns 200 from
getStatusText() which I find strange! If it helps, using a plugin for
Firefox I can see that the Post that occurs when logging in using
Firefox is:
/Main.php?iCmsPageId=32&sAction=CheckLogin
sUsername=username&sPassword=password
so I suppose the questions are, is the PostMethod constructed properly,
does the submit button as seen in this code just below require a name
value pair when no name is specified in the html even though that login
button is the one that is pressed on the site,
<input class="textsubmit" type="submit"
onmouseout="changeTextDecoration(this,'none');"
onmouseover="changeTextDecoration(this,'underline');" style="color:
rgb(226, 0, 110); text-decoration: none;height:16px;" value="Login"/>
does the fact that javascript is required to provide validation with
ValidateForm(this) make a difference to the coding and finally should
the Post text got from a login using Firefox match the result from
authpost.getQueryString() ?
Any answers to these questions would be very welcome?
Thanks very much
