无需用户交互即可获取Office 365 API访问令牌 [英] Get Office 365 API access token without user interaction

问题描述

我想在我的应用程序中添加功能，以便它无需用户交互即可将日历事件添加到Outlook.com.

I want to add a feature to my application so that it will be able to add calendar events to outlook.com without user interaction.

我看到的所有示例都要求用户登录才能访问Office 365 api令牌.我如何在没有用户交互的情况下获得该令牌?

All the examples I've seen require user to login to be able to access office 365 api token. How do i get that token without user interaction?

推荐答案

您可以使用客户端凭据来请求令牌，而不是使用 OAuth 2.0代码授予流程.

You can use the Client Credential to request the token instead of OAuth 2.0 Code Grant flow.

以下是供您参考的请求:

Here is the request for your reference:

POST https://login.microsoftonline.com/<tenantId>/oauth2/token HTTP/1.1
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials
&client_id=<clientId>
&client_secret=<clientSecret>
&resource=https://outlook.office.com

这是使用Microsoft.IdentityModel.Clients.ActiveDirectory请求HTE令牌的示例:

And here is the sample using the Microsoft.IdentityModel.Clients.ActiveDirectory to request hte token:

   public static async Task<string> GetTokenAsync(string resource, string clientId, string secrect)
    {
        string authority = "https://login.microsoftonline.com/{yourTenantName}";
        AuthenticationContext authContext = new AuthenticationContext(authority);

        ClientCredential clientCredential = new ClientCredential(clientId, secrect);
        AuthenticationResult authResult=await authContext.AcquireTokenAsync(resource, clientCredential);
        return authResult.AccessToken;
    }
