PHP cUrl : HTTP Error 400 while The Browser Displayed Correctly

Question

URL:

You can see the url in Here (I put the url in the pastebin because the url is quite long).

Curl & Header :

$header=array();            
$header[]="Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
$header[]="Accept-Encoding: gzip, deflate";
$header[]="Accept-Language: en-US,en;q=0.5";
$header[]="Connection: keep-alive";


$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7');
curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_exec($ch);

Result:

Error 400--Bad Request From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1: 10.4.1 400 Bad Request

The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications."

The Browser when go to the URL directly without curl:

Displayed Nicely.

Answer 1

There are problems with your URL, chances are it was computed wrong.

If you're generating that long URL from your script, make sure it's the right one.

The reason is that if you try deleting stuff, let's say you end up with https://wftc3.e-travel.com/plnext/garuda-indonesia/Override.action, you will see that accessing this page ends up in a 400 error.

I hope this helps.

/edit: this works, so it's probably $url.

<?php

$url = "https://wftc3.e-travel.com/plnext/garuda-indonesia/Override.action?SITE=CBEECBEE&LANGUAGE=ID&EMBEDDED_TRANSACTION=FlexPricerAvailability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
