Keep getting 400 error with cURL on localhost - php

Question

I've been scouring around trying to understand curl and building headers but it seems no matter what I do I get the following error :
HTTP/1.1 400 Bad Request Date: Tue, 12 Apr 2016 18:15:33 GMT Server: Apache/2.2.29 (Unix) mod_wsgi/3.5 Python/2.7.10 PHP/5.6.10 mod_ssl/2.2.29 OpenSSL/0.9.8zh DAV/2 mod_fastcgi/2.4.6 mod_perl/2.0.9 Perl/v5.22.0 Content-Length: 226 Connection: close Content-Type: text/html; charset=iso-8859-1
Bad Request
Your browser sent a request that this server could not understand.
The following is the function that I am using to send post variables and fetch the contents via curl. Both the file doing the fetching and the file whose contents are fetched are being hosted locally on MAMP
$url = "./lib/otherpage.php";
$data = array("url"=>$_POST["url"],"format"=>"json");
function tryCurl($baseurl,$data)
{
$bodydata = array(json_encode($data));
$bodystr = http_build_query($bodydata);
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$baseurl);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$bodystr);
curl_setopt($ch, CURLOPT_PORT,8888);
curl_setopt($ch, CURLOPT_HEADER,1);
curl_setopt($ch, CURLOPT_HTTPHEADER,array(
"POST / HTTP/1.0",
"Content-Type: application/x-www-form-urlencoded",
"Content-Length: ".strlen($bodystr),
"Host: localhost:8888/gt_dev/",
"User-Agent: My-User-Agent 1.0",
"Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
"Cache-Control: no-cache",
"Accept-Language: en;q=0.7,en-us;q=0.3",
"Connection: close",
));
// Execute
$result=curl_exec($ch);
// Printing any errors..
echo curl_error($ch);
curl_close($ch);
return $result;
}
Ultimately, the request should send two post variables ("url" and "format") to the receiving file, and expect a json string in return.

Answer 1

This isn't so much an answer to the original issue but turns out I was thinking about my problem the wrong way.
I wanted to use page A as a proxy to page B. And to pass the same variables page B expected from Page A.
Turns out the same effect can be achieved by simply including page B, not curling the expected parameters to it. So the answer is just
include("./lib/otherpage.php");
