Outlook API 刷新令牌

Question

我使用 simple-oauth2 库来获取令牌，但它只有访问令牌和 id 令牌。

如何获取刷新令牌？

Answer 1

我也有同样的问题。 您需要添加范围参数

['offline_access']

在

authUrl

添加：

 {access_type:'offline', approval_prompt: 'force'}

这将为您提供刷新令牌

auth_tokens

和

id_token

Answer 2

function refresh_token($token)
{
  // Build the form data to post to the OAuth2 token endpoint
  $token_request_data = array(
    "grant_type" => 'refresh_token',
    "refresh_token" => $token,
    "redirect_uri" => 'https://login.microsoftonline.com/common/oauth2/token',
    "resource" => "https://outlook.office365.com/",
    "client_id" => self::$clientId,
    "client_secret" => self::$clientSecret
  );

  // Calling http_build_query is important to get the data
  // formatted as Azure expects.
  $token_request_body = http_build_query($token_request_data);
  error_log("Request body: ".$token_request_body);

  $curl = curl_init(self::$authority.self::$tokenUrl);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($curl, CURLOPT_POST, true);
  curl_setopt($curl, CURLOPT_POSTFIELDS, $token_request_body);
  /*custom*/
  curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
  /*custom end*/
  $response = curl_exec($curl);
  error_log("curl_exec done.");

  $httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
  error_log("Request returned status ".$httpCode);
  if ($httpCode >= 400) {
    return array('errorNumber' => $httpCode,
                 'error' => 'Token request returned HTTP error '.$httpCode);
  }

  // Check error
  $curl_errno = curl_errno($curl);
  $curl_err = curl_error($curl);
  if ($curl_errno) {
    $msg = $curl_errno.": ".$curl_err;
    error_log("CURL returned an error: ".$msg);
    return array('errorNumber' => $curl_errno,
                 'error' => $msg);
  }

  curl_close($curl);

  // The response is a JSON payload, so decode it into
  // an array.
  $json_vals = json_decode($response, true);
  error_log("TOKEN RESPONSE:");
  foreach ($json_vals as $key=>$value) {
    error_log("  ".$key.": ".$value);
  }

  return $json_vals;
}

刷新令牌由授权服务器颁发，由授权服务器自行决定是否颁发。既然您提到了 Outlook API，您可以使用 Microsoft Graph API 来获取刷新令牌。
