oauth2在Microsoft中连接

Question

How can I get events from Office 365 Calendar, from REST?

I create an application in Azure, I have Token from this request:

https://login.microsoftonline.com/common/oauth2/v2.0/authorize?
  client_id=[app_id from AZURE]
  &response_type=code
  &redirect_uri=https://mypage_domain.com
  &response_mode=query
  &scope=https%3A%2F%2Fgraph.microsoft.com%2Fcalendars.read%20
  &state=12345

Next i try get Events:

$ch = curl_init();
$headers = array();
$headers[] = 'Content-Type: application/x-www-form-urlencoded';
$postFields = 'grant_type=authorization_code&code='.$authCode.'&redirect_uri='.$redirectUri.'&scope=openid&client_id='.$clientId.'&client_secret='.$clientSecret;

curl_setopt($ch, CURLOPT_URL,'https://login.microsoftonline.com/common/oauth2/v2.0/token');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$serverOutput = curl_exec ($ch);
curl_close ($ch);
$jsonOutput = json_decode($serverOutput, true);

$chUser = curl_init();
$headersUser[] = 'Authorization: Bearer '.$jsonOutput['id_token'];
curl_setopt($chUser, CURLOPT_URL,'https://graph.microsoft.com/v1.0/me/events/');
curl_setopt($chUser, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($chUser, CURLOPT_HTTPHEADER, $headersUser);
$serverOutputUser = curl_exec($chUser);
curl_close($chUser);

But I get an error: Access token validation failure .

What did I do wrong? I found examples for Laravel but I need simple, universal code. I need use this in Wordpress to write events from calendar for page users.

You are indicating wrong authorization header. In fact, the authorization header uses bearer token which has the structure: Bearer <access_token> .

$headersUser[] = 'Authorization: Bearer '.$jsonOutput['**access_token**'];
