PHP cUrl : HTTP Error 400 while The Browser Displayed Correctly

curlhttp-status-code-400PHP

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.

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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

Php curl returns 400 Bad Request if does in a loop

Your problem regarding the multiplying headers is at the top of the get method:

$this->headers[] = 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8, image/gif, image/x-bitmap, image/jpeg, image/pjpeg';
$this->headers[] = 'Connection: Keep-Alive';
$this->headers[] = 'Content-type: application/x-www-form-urlencoded;charset=UTF-8';

On each iteration you are adding the same headers to the headers array of the object instance. (Saying array[] appends to the array.) You need to either reset the array on each iteration or perhaps move the headers setting into another method.

If headers is always and only set in the get method, you can change it to this in order to fix the problem:

$this->headers = array(
    'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8, image/gif, image/x-bitmap, image/jpeg, image/pjpeg',
    'Connection: Keep-Alive',
    'Content-type: application/x-www-form-urlencoded;charset=UTF-8'
);

...but if the headers are always the same and never changed between iterations, you might as well set the headers' value in the object constructor and only read from it in the get method, since resetting the array to the same value all the time is redundant.
