微软中的oauth2连接

Question

如何从Office 365日历和REST获取事件？

我在Azure中创建了一个应用程序，我有来自此请求的令牌：

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

接下来，我尝试获取事件：

$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);

但是我得到一个错误：Access token validation failure。

我做错什么了？我找到了Laravel的示例，但我需要简单、通用的代码。我需要在Wordpress中使用它来为页面用户从日历中编写事件。

您指示的授权头错误。实际上，authorization头部使用的是Bearer <access_token>结构的持有者令牌。

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