XF 2.1 Guzzle Change Information

If you're using Guzzle to get json information from another site, you need to do this in XenForo 2.1...

As an object:
Code: 
$values = \GuzzleHttp\json_decode($response->getBody());

As an array:
Code: 
$values = \GuzzleHttp\json_decode($response->getBody(), true);
 
So If I'm using this:
PHP: 
$request = $client->get(self::DATA_URL);
$data = (string) $request->getBody();
$response = json_decode($data, true);

I just need to do this?
PHP: 
$request = $client->get(self::DATA_URL);
$data = (string) $request->getBody();
$response = \GuzzleHttp\json_decode($data, true);
 
If you're getting a file (as it appears from the string modifier) keep using the first one.

Normally I used $response->json(); which WAS a Guzzle function, but because Guzzle changed I switched to \GuzzleHttp\json_decode($response->getBody(), true);.

If you're getting a json response you only need $response = \GuzzleHttp\json_decode($response->getBody(), true);. So it would be...

Code: 
$request = $client->get(self::DATA_URL);
$response = \GuzzleHttp\json_decode($request->getBody(), true);

That will put the json response into an array.
 
Is there an advantage to doing:
Code: 
\GuzzleHttp\json_decode($response->getBody(), true);
over just...
Code: 
json_decode($response->getBody(), true);
 
None that I know of other than keeping with the Developer guidelines and using functions built in to XenForo.

My IDE (PHP Storm) automatically selected the Guzzle function when I used json_decode on XF 2.1. ;)
 
Just for people who don't know this, I'll add that you don't need to write separate add-ons for 2.0 and 2.1...

Code: 
if(\XF::options()->currentVersionId >= '2010031')
{
    $yourInfo = \GuzzleHttp\json_decode($response->getBody(), true);
}else{
    $yourInfo = $response->json();
}

I'm afraid I'm getting an error with the change you provided. Do you have any ideas? Thank you!

That's nothing to do with your code, that's an error coming from the request.

Thanks Chris. That makes sense, because my add-on on my production site stopped getting new data around 2 days ago, but if I go to the json url, I can see that there's new data. But I'm not getting any errors on my production site, so that's weird.
 
Actually if I go to https://api.developertracker.com/anthem/posts' (with the single quote at the end), I get this:

188691

The server error I posted above shows a 502 error. I double checked in my code to see if I added a single quote by mistake, but there isn't one, which you can see here: const DATA_URL = 'https://api.developertracker.com/anthem/posts';

I'm at a loss as for what's going on.
 
Interestingly enough, this code works for me without a problem in XF 2.1:

Code: 
try
{
    $client = \XF::app()->http()->client(['headers' => ['Accept' => 'application/json']]);
    $response = $client->get("https://api.developertracker.com/anthem/posts");
}
catch (\GuzzleHttp\Exception\RequestException $e)
{
    if (null !== $e->getResponse())
    {
        $error = 'Tracker Error ' . $e->getResponse()->getStatusCode() . ': ' . $e->getResponse()->getReasonPhrase();
    }
    else
    {
        $error = $e->getMessage();
    }

    return $this->error($error);
}

$yourInfo = \GuzzleHttp\json_decode($response->getBody(), true);
print_r($yourInfo);
die();

Honestly, going forward I'm requiring 2.1 for all my future updates anyways. The share/bookmark/reaction functions are just too useful to ignore.

Same, especially given how Composer dependencies are sneaking into a lot of my mods these days. Anything but the smallest mods where no changes are needed is getting a minver bump.

Thank you Snog, that worked perfectly.
 
Updated code:

Code: 
try
{
    $client = \XF::app()->http()->client();
    $response = $client->get("https://api.developertracker.com/anthem/posts", ['headers' => ['Accept' => 'application/json']]);
}
catch (\GuzzleHttp\Exception\RequestException $e)
{
    if (null !== $e->getResponse())
    {
        $error = 'Tracker Error ' . $e->getResponse()->getStatusCode() . ': ' . $e->getResponse()->getReasonPhrase();
    }
    else
    {
        $error = $e->getMessage();
    }

    return $this->error($error);
}

$yourInfo = \GuzzleHttp\json_decode($response->getBody(), true);
print_r($yourInfo);
die();

Try removing this...
, ['headers' => ['Accept' => 'application/json']]

With my original example, the headers weren't being sent anyway. So removing it from the request should end up with the same result. ;)

EDIT: Yep, removing that works. :D
I discovered the headers weren't being sent here..

XF 2.1 - How to use the API

In regards to the new API and the introduction here: https://xenforo.com/community/threads/rest-api.155632/ What are the first steps to using the API? In the Admin control panel I created an API key. I assume I should be able to put in the address bar of my browser the following example to...

But you don't need them for your purpose.
