使用Java中的Office 365 REST API构建守护程序或服务应用程序

提问于

我正在尝试构建一个批处理作业来访问Office 365 Mail API . 在检查documentation(概念非常清楚)时,我找不到this但它依赖于java pom文件但我希望尽可能直接使用REST API或Graphi API .

有人可以指出我如何开始构建一个Daemon服务来访问Office 365 REST API而无需用户登录?

UPDATE

我有以下代码来使用AADL库获取令牌

String tenant="....";
        String authority = "https://login.windows.net/"+tenant+"/oauth2/authorize";
        ExecutorService service=null;
        service= Executors.newFixedThreadPool(1);

        try{

            AuthenticationContext authenticationContext= new AuthenticationContext(authority,false,service);
            String certFile="/mycert2.pfx";
            InputStream pkcs12Cert= new SharedFileInputStream(certFile);

            AsymmetricKeyCredential credential=AsymmetricKeyCredential.create("....",pkcs12Cert,"pass");


            Future<AuthenticationResult> future=authenticationContext.acquireToken("https://outlook.office365.com",credential,null);

            System.out.println("Token Received"+future.get().getAccessToken());
            String token = future.get().getAccessToken();

            HttpGet httpGet = new       HttpGet("https://graph.microsoft.com/v1.0/users");

            httpGet.setHeader("Authorization", "Bearer "+token);


            GraphServices graphServices = new GraphServices();
            ResponseEntity<String> responseEntity;


            //responseEntity = graphServices.getEmails(token); //Throws the same Unauthorized exception 

            HttpClient httpClient= HttpClients.createDefault();

            HttpResponse response=httpClient.execute(httpGet);
//response contains Unauthorized access 
            HttpEntity entity=response.getEntity();

        }
        catch (MalformedURLException e){
            e.printStackTrace();

        }
        catch (Exception e){
            e.printStackTrace();
        }


    }

这里是来自http.execute方法的Unauthorized错误

(令牌与此类似,只是将其更改为类似的安全性)

    这里的Java演练(虽然对于使用auth代码流的Web应用程序):https://dev.outlook.com/restapi/tutorial/java

    还有一个使用客户端凭据流的示例:

    要在守护程序或服务应用程序中进行身份验证,我们可以使用 Client Credentials flow . 注册应用程序后,我们将获得 secret . 然后我们可以直接使用下面的请求来获取仅限应用访问令牌:

    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://graph.microsoft.com
    

    要使用Office 365访问令牌,我们可以使用 https://outlook.office.com 替换资源 . Here是有关在服务或守护程序应用程序中调用Microsoft Graph的详细文档 .
