Guzzle error with Jeffreys example

Check out http://docs.guzzlephp.org/en/latest/quickstart.html#creating-a-client

The URI you're passing into client should be within an array, with a base_uri key

Ok. So now I have:
Route::get('users/{username}', function ($username)
{
$client = new \GuzzleHttp\Client(['base_uri' => 'https://api.github.com/']);
$response = $client->get("users/$username")->send();
dd($response->json());
});

But then I receive this error:
Call to undefined method GuzzleHttp\Psr7\Response::send()

When you use get(), it's a response object, as the error hints.

So if we have a look at the following: http://docs.guzzlephp.org/en/latest/quickstart.html#using-responses

You can see that there's no need to send(), we now need to process the response with these methods.

For example, try replacing send() with getContents()

I see. getContents() didn't work, but if I simply use:
$response = $client->get("users/$username");
dd($response);

I receive the following:
Response {#141 ▼
-reasonPhrase: "OK"
-statusCode: 200
-headers: array:22 [▶]
-headerLines: array:22 [▶]
-protocol: "1.1"
-stream: Stream {#139 ▶}
}

But it doesn't display the public user information like in Jeffreys video.

EDIT: I finally got it working! The result doesn't show as a list like in the example video, but it displays from left to right. Anyway, the important thing is that it works. I believe the reason it didn't work following Jeffreys video is that Guzzle now is a newer version and has deprecated some of the methods. Anyone able to confirm this?

So here is the code that ended up working for me:
Route::get('users/{username}', function ($username)
{
$client = new GuzzleHttp\Client(['base_uri' => 'https://api.github.com/']);
$response = $client->get("users/$username");
echo $response->getBody();
die();
});

Thanks for the help taijuten!
