Microsoft graph Unable to read JSON request payload

问题

I'm trying to create subscriptions with microsoft graph in php, however I am unable to see what is going wrong at this point.

The code is breaking at the following:

protected $http_subscribe = "https://graph.microsoft.com/v1.0/subscriptions";

public function getSubscriptions()
{
    if(empty($this->token)) {
        dd('no token supplied'); //some debugging
    }

    $date = $this->endTimeDate->format('Y-m-d'); //This is Carbon date

    $time = $this->endTimeDate->format('H:i:s.u');

    $response = $this->client->request('POST', $this->http_subscribe, [
        'headers' => [
            'Authorization' => 'Bearer ' . $this->token,
            'Content-Type' => "application/json"
        ], 'form_params' => [
            "changeType" => "created,updated",
            "notificationUrl" => "https://website.test/notify",
            "resource" => "me/mailFolders('Inbox')/messages",
            "expirationDateTime" => $date.'T'.$time,
            "clientState" => "secretClientValue"
        ]
    ]);

    dd($response);
}

The full error I'm getting is:

"""
{\r\n
  "error": {\r\n
    "code": "BadRequest",\r\n
    "message": "Unable to read JSON request payload. Please ensure Content-Type header is set and payload is of valid JSON format.",\r\n
    "innerError": {\r\n
      "request-id": "063d9947-80fd-461d-a70e-q0bd8eee9d56",\r\n
      "date": "2018-08-07T08:20:54"\r\n
   }\r\n
  }\r\n
}
"""

Now I get what the error says, my json would be invalid, however this array is in correct json format, I'm using Guzzle as my Client.

You should use json option. Try this:

$response = $this->client->request('POST', $this->http_subscribe, [
   'headers' => [
       'Authorization' => 'Bearer ' . $this->token,
   ],
   'json' => [
       "changeType" => "created,updated",
       "notificationUrl" => "https://website.test/notify",
       "resource" => "me/mailFolders('Inbox')/messages",
       "expirationDateTime" => $date.'T'.$time,
       "clientState" => "secretClientValue",
   ],
]);
