Make a GET with Guzzle in Laravel 5.1

Question

I have an API, and make GET to it via Postman:

Ex.http://site/api/users.count

I got

{
    "status": 200,
    "message": "Success",
    "data": {
        "count": 8
    }
}

I've tried to use Guzzle:

composer require guzzlehttp/guzzle

use GuzzleHttp\Client;

---

use it

$client = new Client();
$res = $client->request('GET','http://site/api/users.count');

---

result

dd($res->getStatusCode());

I got 200

dd($res->getBody());

Stream {#662 ▼
  -stream: stream resource @272 ▼
    wrapper_type: "PHP"
    stream_type: "TEMP"
    mode: "w+b"

  }
  -size: null
  -seekable: true
  -readable: true
  -writable: true
  -uri: "php://temp"
  -customMetadata: []
}

dd($res);

I got

expected result

I am hoping to get a similar result like this :

{
    "status": 200,
    "message": "Success",
    "data": {
        "count": 8
    }
}

How can I debug this?

Answer 1

You can see by the response headers that everything went OK. Status code is 200, Content-Length is not 0, etc.

The body of the response is in the body property of GuzzleHttp\Psr7\Response and it's a GuzzleHttp\Psr7\Stream. You can access it with the getBody() method.

You can use read($n) to read n bytes from the response, or get the whole response by casting the Stream to a string, either implicitly (via echo) or explicitly (with a cast operator):

var_dump((string) $res->getBody()); // explicitly
echo $res->getBody(); // implicitly

For future reference, you can use the debug mode to see more information about the whole request:

$res = $client->request('GET','http://site/api/users.count', ["debug" => true]);

Answer 2

You have to use $response->getBody(); you can also do things like ->getStatusCode(); Try and see their docs, there are a lot of options but to get the content use the getBody function

In your exact case dd($res->getBody());
