PHP cURL没有错误，但不起作用

Question

I've been banging my head on this for a while now and I'm sorta fed up. I'm not a PHP programmer so I might be missing something that is not immediately obvious to my Python infused brain.

So here's the context. I need to write a script to login automatically into a web interface and run a search, and well, absolutely everything I've tried to do seems to fail miserably.

Here's my code:

<?php
echo 'start';
// INIT CURL
$ch = curl_init();

// SET URL FOR THE POST FORM LOGIN
curl_setopt($ch, CURLOPT_URL, 'https://W0110DcIpsOcsRpt02/si_ocs_gui/login.php');

// ENABLE HTTP POST
curl_setopt ($ch, CURLOPT_POST, 1);

// SET POST PARAMETERS : FORM VALUES FOR EACH FIELD

curl_setopt ($ch, CURLOPT_POSTFIELDS, 'username=*****&password=*****&btnSubmit=Login');

// IMITATE CLASSIC BROWSER'S BEHAVIOUR : HANDLE COOKIES
curl_setopt ($ch, CURLOPT_COOKIEJAR, '/var/tmp/cookie.txt');

# Setting CURLOPT_RETURNTRANSFER variable to 1 will force cURL
# not to print out the results of its query.
# Instead, it will return the results as a string return value
# from curl_exec() instead of the usual true/false.
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt ($ch, CURLOPT_FRESH_CONNECT, 1);

// EXECUTE 1st REQUEST (FORM LOGIN)
$store = curl_exec ($ch);

if($store == False){
        echo " store false ";
        echo curl_error($ch);
} else {
        echo " store true ";
        echo $store;
}

// SET FILE TO DOWNLOAD
echo ' second_request ';
curl_setopt($ch, CURLOPT_URL, 'https://W0110DcIpsOcsRpt02/si_ocs_gui/FWOCS1_BL_SUBSCRIBERS_list.php');
curl_setopt ($ch, CURLOPT_POST, 1);
#curl_setopt ($ch, CURLOPT_POSTFIELDS, 'value_ACCESS_NO_4=15142351150');
curl_setopt ($ch, CURLOPT_POSTFIELDS, 'q=\(SUBSCRIBER_ID~equals~1545303\)');
// EXECUTE 2nd REQUEST (FILE DOWNLOAD)
if(!$store == False){
        $content = curl_exec ($ch);
        echo $content;
}
// CLOSE CURL

curl_close($ch);

echo ' done';
?>

The behaviour of this is as follows. I run the script, and it fails at the first cURL request (the login) and returns no errors. I have modified this line here:

curl_setopt ($ch, CURLOPT_POSTFIELDS, 'username=*****&password=*****&btnSubmit=Login');

by removing the btnSubmit=Login part and I get the login page displayed with the filled in username and password fields. I can press the login button and it will work. However, it seems that my lack of web development is biting me here and I have no idea how that button works. So, here's the code inspected with firebug:

<a class="rnr-button main" href="#" onclick="document.forms[0].submit();return false;">Submit</a>

I also went directly in the PHP code on the web server and found the button corresponding to it:

if ((@$_POST["btnSubmit"] == "Login" || $adSubmit) && $logacc)

Hence why I was trying the btnSubmit=Login .

So my question is pretty simple: what am I doing wrong and how can I get the results I need?

Answer 1

I have got the same problem and find the solution for it.

Code

CURLOPT_RETURNTRANSFER => false

Use this to solve your problem.
