symfony2 Get exact content from BuzzBundle response

Question

How can I get exact content from BuzzBundle without header or other information

currently I am using ,

 $buzz = $this->container->get('buzz');
 $response = $buzz->get('http://api.ipify.org?format=json');
 echo $response;

and output is,

HTTP/1.1 200 OK Server: Cowboy Connection: close Access-Control-Allow-Origin: * Content-Type: text/plain Date: Thu, 13 Nov 2014 14:51:40 GMT Content-Length: 14 Via: 1.1 vegur {"ip":"54.254.210.209"}

here only {"ip":"111.20.67.90"} is desired response.

or any other way to do so, with different bundle, or i have to use curl directly in PHP code ?

For posterity, BuzzBundle is just a small configuration file that injects the Buzz library into Symfony.

When you use the get() method of Browser, it returns an instance of call() with a return value of MessageInterface... so let's examine that file:

/**
 * Returns the message document.
 *
 * @return string The message
 */
public function __toString();

This is just the equivalent of a header file if you're familiar with C++, but it's clear that the __toString() file returns the full message, including headers. So if we look through the rest of that file, we find that there's another function that gets what you want:

/**
 * Returns the content of the message.
 *
 * @return string The message content
 */
public function getContent();

So if you treat the MessageInterface as an object instead of trying to access it like a string (which gives you its default of __toString()), this is the code you would use:

$buzz = $this->container->get('buzz');
$response = $buzz->get('http://api.ipify.org?format=json');
echo $response->getContent(); // output: {"ip":"54.254.210.209"}
