如何使用OAuth进行身份验证以访问EWS API [英] How to authenticate with OAuth to access EWS APIs

问题描述

我的Web服务当前正在执行基本的用户名/密码身份验证，以便订阅交换用户以接收事件(例如新邮件事件等)，如下所示:

My web service is currently doing basic username/password authentication in order to subscribe the exchange user for receiving the events (like new mail event etc) like below:

var service = new ExchangeService(exchangeVersion)
                                  {
                                      KeepAlive = true,
                                      Url = new Uri("some autodiscovery url"),
                                      Credentials = new NetworkCredential(username, password)
                                  };

var subscription = service.SubscribeToPushNotifications(
                                    new[] { inboxFolderFoldeID },
                                    new Uri("some post back url"),
                                    15,
                                    null,
                                    EventType.NewMail,
                                    EventType.Created,
                                    EventType.Deleted,
                                    EventType.Modified,
                                    EventType.Moved,
                                    EventType.Copied);

现在，我应该替换身份验证机制以使用OAuth协议.我看到了一些示例，但所有示例似乎都在谈论对客户端进行身份验证( https://msdn.microsoft.com/zh-CN/library/office/dn903761%28v=exchg.150%29.aspx?f= 255& MSPPError = -2147217396 )，但我无处找不到如何使用OAuth协议对交换用户进行身份验证的示例.任何代码示例都会有很大帮助.谢谢.

Now, I am supposed to replace the authentication mechanism to use OAuth protocol. I saw some examples but all of them seem to be talking about authenticating the client (https://msdn.microsoft.com/en-us/library/office/dn903761%28v=exchg.150%29.aspx?f=255&MSPPError=-2147217396) but nowhere I was able to find an example of how to authenticate an exchange user with OAuth protocol. Any code sample will help a lot. Thanks.

推荐答案

以防有人仍在努力使其正常工作.我们需要在Azure门户上为该应用程序上载证书清单，然后使用相同的证书对客户端进行身份验证以获取访问令牌.有关更多详细信息，请参阅: https://blogs.msdn.microsoft.com/exchangedev/2015/01/21/building-daemon-or-service -apps-with-office-365-mail-calendar-and-contacts-apis-oauth2-client-credential-flow/

In case someone is still struggling to get it to work. We need to upload a certificate manifest on azure portal for the application and then use the same certificate to authenticate the client for getting the access token.
