Batch Request Support

[Ndiritu]

I'm trying to convert my application to the new fluent API. I specifically want to download profile photos for all the users in my organization, and was able to do individual photos using

$photoContent = $this->graphServiceClient->usersById($user->id)->photo()->content()->get()->wait();

But in previous versions I could make an array of requests and send them all at once like

$data = $this->graph
            ->createRequest('POST', '/$batch')
            ->attachBody(json_encode(['requests' => $requests]))
            ->execute();

I can't for the life of me figure out how to do this now. Is this even possible with the fluent API? I am tempted to go back to the old API and lock my composer.json at msgraph-sdk-php RC4 so my old code works.

Any advice on how I could approach this would be appreciated!

We are yet to provide batch request support via the fluent API in 2.0-RC5.

However, in the meantime you can create a Graph-configured guzzle client and configure batch requests on the guzzle client.

There is a limitation however that you'll be unable to leverage the models provided i.e. serializing models to the request payload or deserialization.

$guzzleClient = GraphClientFactory::create();
$response = $guzzleClient->post('/$batch', ...);   

Refer to the Guzzle docs on how to add the request body, headers etc
