Question

Hi wondring whats the difference between $response->getBody() and $response->getRawBody();

$this->_client->setUri('http://www.google.com/ig?hl=en');
        try {
            $response = $this->_client->request();
        }catch(Zend_Http_Exception $e)
        {
            echo 'Zend http Client Failed';
        }
        echo get_class($response);
        if($response->isSuccessful())
        {
           $response->getBody();
           $response->getRawBody();

        }

getRawBody() returns the body of the http response as is.

getBody() adjust for certain headers i.e. decompresses content sent with gzip or deflate content-encoding headers. Or the chunked transfer-encoding header.

The simplest way figure these questions out in to simply look at the code. Also a great learning experience. Code is edited for brevity.

public function getRawBody()
{
    return $this->body;
}

public function getBody()
{
    $body = '';

    // Decode the body if it was transfer-encoded
    switch (strtolower($this->getHeader('transfer-encoding'))) {
        case 'chunked':
            // Handle chunked body
            break;
        // No transfer encoding, or unknown encoding extension:
        default:
            // return body as is
            break;
    }

    // Decode any content-encoding (gzip or deflate) if needed
    switch (strtolower($this->getHeader('content-encoding'))) { 
        case 'gzip':
             // Handle gzip encoding
            break;
        case 'deflate':
            // Handle deflate encoding
            break;
        default:
            break;
    }

    return $body;
}
