cannot set $oDoc.cookie

[tom13]

I'm trying to first get a cookie and then replace a certain server Id with a new one. This is to test each application server for our internal application.

The following is my function of interest:

expandcollapse popup

Func checkAppServer($id)

debug("checking app server for id " & $id)

;access application with app server cookie
ShellExecute("iexplore.exe", "about:blank")
WinWait("Blank Page")
Local $oIE = _IEAttach("about:blank", "url")
_IELoadWait($oIE)
_IENavigate($oIE, "https://application.example.com")
If @error Then
alert("Login checker failed to access application.")
Return
EndIf

;get the document
Local $oDoc = _IEDocGetObj($oIE)
If @error Then
alert("Login checker failed to get the document object.")
Return
EndIf

;get current cookies
$newCookies = $oDoc.cookie
debug("current cookie string: " & $newCookies)

;replace all app server IDs with this ID
For $sServerId In $aAppServerIds
If $sServerId == $id Then ContinueLoop

debug("checking if we are currently on server " & $sServerId)

$newCookies = StringReplace($newCookies, $sServerId, $id, 0, 0)
If @extended Then
debug("replaced old server id " & $sServerId & " to new server id " & $id)
debug("new cookies string: " & $newCookies)
EndIf
Next

;ensure that we are now on the server of interest
If Not StringInStr($newCookies, $id) Then
alert("LoginChecker failed to navigate to server with id " & $id & ". Please fix the script!")
Exit
EndIf

debug("overwriting document.cookie")
$oDoc.cookie = $newCookies
debug("new document.cookie: " & $oDoc.cookie)

Exit

;verify HTTP body

EndFunc

The following output is returned:

checking app server for id ffffffffaf1c7718

current cookie string: usernameType=student; COOKIE_CONSENT_ACCEPTED=true; NSC_100732.qspe1_wjq1c.hspvq=ffffffffaf1c771d45525d5f4f58455e445a4a42378b; JSESSIONID=5EB0C22CD06E6D904653F663670B3056.root; session_id=EF0ABD73D15B5E4431CD59107946E9A9; s_session_id=0D26A888B87A5CF9D07020CF5B5A5955

overwriting document.cookie

new document.cookie: usernameType=student; COOKIE_CONSENT_ACCEPTED=true; NSC_100732.qspe1_wjq1c.hspvq=ffffffffaf1c771d45525d5f4f58455e445a4a42378b; JSESSIONID=5EB0C22CD06E6D904653F663670B3056.root; session_id=EF0ABD73D15B5E4431CD59107946E9A9; s_session_id=0D26A888B87A5CF9D07020CF5B5A5955

This means that:

• the cookie is retrieved correctly

• the ID of interest is replaced correctly, and set to $newCookies

• when executing $oDoc.cookie = $newCookies, $oDoc.cookie does not actually change

Why does it appear impossible to set $oDoc.cookie? Edited July 19, 2012 by tom13

When you set cookie as stated on this page, they use escape to encode the string. Maybe that would help?

And a UDF:

Thanks, I was hoping this would be it. Unfortunately encoding the string before setting $oDoc.cookie appears to have no effect at all. Same story when I also decode the cookie before retrieving it.

Any other ideas?

Hmm, that is somewhat confusing. Do you have any idea how I would now replace the entire cookie?

I think it's pretty clear - pair by pair.

That doesn't seem to work, for some reason it adds the cookie and duplicates it instead of replacing it.

My code:

$oDoc.cookie = $sName & "=" & $sVal

Resulting cookie string:

NSC_100732.qspe1_wjq1c.hspvq=ffffffffaf1c771845525d5f4f58455e445a4a42378b; JSESSIONID=037CE036F417243612A9766EC519EDF5.root; NSC_100732.qspe1_wjq1c.hspvq=ffffffffaf1c771b45525d5f4f58455e445a4a42378b; JSESSIONID=0EC325282EF8D5E4811AA444E64AA2FF.root

Obviously, only the first "NSC_100732.qspe1_wjq1c.hspvq" cookie should be there, not the second (this is the old one).

Figure out what you are doing differently from this example:

#include <IE.au3>

$oIE = _IECreate("www.google.com")

$oIE.document.cookie = "test_cookie=one; path=/;"
ConsoleWrite($oIE.document.cookie & @CRLF)

$oIE.document.cookie = "test_cookie=two; path=/;"
ConsoleWrite($oIE.document.cookie & @CRLF)

_IEQuit($oIE)
