CURL Problem.. Comparing output from IE/CURL differs

P: n/a
I'm writing a tiny php app that will log into our bank of america
account and retrieve a file containing a list of checks that cleared
the previous day. The problem I'm running into is when I perform
actions with php/CURL the output is different than when I use IE and
I'm completely stumped as to why. The final output should list files
available for retrieval but the CURL output displays an error/empty
file message.

Here is the curl portion of my code

global $ERROR_MESSAGE;

$ch = curl_init();
$POSTFIELDS =
"remote=MYLOGIN&password=MYPASSWORD&Submit=Submit& operation=LOGON";

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_URL,
"https://elink-http4.bankofamerica.com/servlet/MailboxServlet");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE
5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "$POSTFIELDS");
curl_setopt($ch, CURLOPT_COOKIEJAR, "/ReconsileCookie");

$stuff=curl_exec($ch);
curl_close($ch);

echo $stuff;
$pos = strrpos($stuff, "Logon is successful.");
if ($pos === false)
$ERROR_MESSAGE = "\tUnable to login.\n";

if (curl_errno($ch))
$ERROR_MESSAGE = "\t" . curl_error($ch) . "\n";
if ($ERROR_MESSAGE == "") { // Login succesfull... Continue retrieval
of file
$ch = curl_init();

$formvars = array();
$formvars["Submit"]="Submit";
$formvars["operation"]="DIRECTORY";

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_URL,
"https://elink-http4.bankofamerica.com/servlet/MailboxServlet");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE
5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $formvars);
curl_setopt($ch, CURLOPT_COOKIEFILE, "/ReconsileCookie");

$stuff=curl_exec($ch);
curl_close($ch);
echo $stuff;

$pos = strrpos($stuff, "Send is successful.");
if ($pos === false)
$ERROR_MESSAGE ="\tFailed to send edi.txt to bank.\n";
if (curl_errno($ch))
$ERROR_MESSAGE = "\t" . curl_error($ch) . "\n";

}

Below is the output I get when I execute the above portion of code

<html>
<body>

<HTML>
<HEAD><LINK rel="stylesheet" type="text/css" name="defaultstyle"
href="/cehttp/html/style.css">
<TITLE>Servlet Response Message</TITLE></HEAD>
<BODY>
<H2 align=center>Servlet has returned the following message</H2>
<HR>
Logon is successful.
<HR>
</BODY></HTML>
<HTML>
<HEAD><LINK rel="stylesheet" type="text/css" name="defaultstyle"
href="/cehttp/html/style.css">
<TITLE>Servlet Response Message</TITLE></HEAD>
<BODY>
<H2 align=center>Servlet has returned the following message</H2>
<HR>
The file is empty or does not exist. Return Code: 701
<HR>
</BODY></HTML>

</body>
</html>
Now, if I use IE to login to the website I recieve

<HTML>
<HEAD><LINK rel="stylesheet" type="text/css" name="defaultstyle"
href="/cehttp/html/style.css">
<TITLE>Servlet Response Message</TITLE></HEAD>
<BODY>
<H2 align=center>Servlet has returned the following message</H2>
<HR>
Logon is successful.
<HR>
</BODY></HTML>

After I login I continue with the button to display my file directory
contents and the output is as follows
<HTML><HEAD><LINK rel="stylesheet" type="text/css" name="defaultstyle"
href="/cehttp/html/style.css">
<TITLE>CONNECT:Enterprise -Directory</TITLE></HEAD>
<BODY>
<CENTER><TABLE BORDER=1>
<CAPTION>CONNECT:Enterprise Directory Contents</CAPTION>
<TR>
<TH>Mailbox</TH>
<TH>Batch#</TH>
<TH>Size</TH>
<TH>Description (Batch ID)</TH>
<TH>Creation Date</TH>
<TH>Creation Time</TH>
<TH>Flags</TH>
</Table></CENTER>
<CENTER>Number of batches: 0</CENTER>
</BODY></HTML>

Here is the HTML source for the login page.
<HTML>
<HEAD>
<LINK rel="stylesheet" type="text/css"
name="defaultstyle" href="style.css"><TITLE>CONNECT:Enterprise -
Logon</TITLE>
</HEAD>
<BODY >
<H2>Logon Option</H2>

<FORM METHOD="POST" ACTION="/servlet/MailboxServlet">

<P><table border=1 cellpadding=4 cellspacing=4
summary="Instruction box"><tr><td bgcolor="#CC0000"><font
color="#FFFFFF"><b>To log on, fill in the necessary fields below and
click on the Submit button.</b></font>
</td></tr>
</table></P>

<table border=0 cellpadding=0 cellspacing=0>
<tr><td>User ID: </td><td><INPUT TYPE="TEXT"
NAME="remote" SIZE="9" MAXLENGTH="64"></td></tr>
<tr><td>Password:</td><td><INPUT
TYPE="PASSWORD" NAME="password" SIZE="9" MAXLENGTH="16"></td></tr>

</table>

<P><INPUT TYPE="SUBMIT" NAME="Submit" VALUE="Submit"
CHECKED="CHECKED">
<INPUT TYPE="RESET" NAME="Cancel" VALUE="Reset"></P>
<INPUT TYPE="HIDDEN" NAME="operation" VALUE="LOGON">

</FORM>
</BODY>
</HTML>

And here is the source for the 2nd Post data page

<HTML>

<HEAD>
<LINK rel="stylesheet" type="text/css" href="style.css">
<TITLE>CONNECT:Enterprise - Directory</TITLE>

</HEAD>

<BODY>
<FORM METHOD="POST" ACTION="/servlet/MailboxServlet">

<H2>Directory Option</h2>

<table border=1 cellpadding=4 cellspacing=4 summary="Instruction
box"><tr><td bgcolor="CC0000"><font color="#FFFFFF"><strong>To see and
download available files, click on the Submit
button.</strong></font></td></tr>
</table>
<br>

<P><INPUT TYPE="SUBMIT" NAME="Submit" VALUE="Submit" CHECKED="CHECKED">
<INPUT TYPE="HIDDEN" NAME="operation" VALUE="DIRECTORY"></P><br>
</FORM>
</BODY>
</HTML>

Any ideas as to why CURL produces different results? Also I've already
used a CURL based app using almost the identical code above to login
and send a checks cut today file which correctly works..
Thanks

From a brief glance this is the only bit that looked slightly odd - is this a
valid, writable file for the cookie jar?

Yes, the cookie itself is correctly created and correctly loaded.
Originally I set it to just "cookie" but I wanted to keep it seperate
so I changed the name to a more recognizable one.

I found the issue..
If I use
curl_setopt($ch, CURLOPT_POSTFIELDS,
"operation=DIRECTORY&Submit=Submit");

it works
but with

$formvars = array();
$formvars["Submit"]="Submit";
$formvars["operation"]="DIRECTORY";
curl_setopt($ch, CURLOPT_POSTFIELDS, $formsvars);

it does not..
Any idea why?

Maybe:

http://cvs.php.net/php-src/ext/curl/interface.c

Particularly look at revisions 1.30 and 1.46 and the bug it references?

It's not exactly well documented when you're supposed to pass as the parameter
when using CURLOPT_POSTFIELDS.

' CURLOPT_POSTFIELDS The full data to post in a HTTP "POST" operation.'

This seems to mean the raw POST data as per your first bit of code, but some
versions of the PHP curl extension seem to accept arrays (which is useful).
Looking at the code it appears to accept objects too.

Well, the strange thing is I've used an array before for passing post
data and it worked correctly.

I have seen this behaviour with some version of Curl that do not handle
HTTP 1.1 responses with code 100. This is not an error but CUrl could
not handle it properly.

Personally I use this HTTP client class that uses fsockopen with OpenSSL
when available. Otherwise, internally it falls back to curl but changes
the request a bit to avoid the bug. You may want to try the class to see
if it solves your problem too:
