java - 403 :forbidden when reading mails from server side application using Microsoft Graph

Question

我正在开发一个服务器端应用程序，用于从 Office 365 检索电子邮件、过滤电子邮件并将其存储在我们的数据库中，而无需用户登录。如果您想查看一些详细信息，Here 是我之前问题的链接。

我有以下方法

@Test
    public void testGetAccessTokenDeamon() throws Exception {

        String tenant="f0245-fd24-r3s-be8a-7745gra60be3";
        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="/mycert.pfx";
            InputStream pkcs12Cert= new SharedFileInputStream(certFile);

            AsymmetricKeyCredential credential=AsymmetricKeyCredential.create("g564f4-e53c-45b7-938a-gt6445gy667",pkcs12Cert,"passwd");


            Future<AuthenticationResult> future=authenticationContext.acquireToken("https://graph.microsoft.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);




            //HttpClient httpClient= HttpClients.createDefault();

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

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

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


    }

public ResponseEntity<String> getEmails(String accessToken) throws Exception
    {
        logger.info("In getEmails");

        RestTemplate restTemplate = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
        HttpEntity<String> request;

        headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
        headers.add(AuthorizationConstants.AUTHORIZATION, AuthorizationConstants.BEARER + " " + accessToken);
        request = new HttpEntity<String>(headers);

        ResponseEntity<String> response = restTemplate.exchange("https://graph.microsoft.com/v1.0/users/abc@microsoft.com/messages", HttpMethod.GET, request, String.class);
        return response;
    }

如果我尝试在restTemplate中使用 https://graph.microsoft.com/v1.0/users/ ，我将获得用户列表，但对于特定用户，上述代码将返回403。

您能否建议我使用哪些端点，以便我的应用程序无需用户登录即可访问个人消息？我已经向该应用授予了所有必要的权限(委托(delegate)和应用权限)。

更新:这是我在 http://jwt.calebb.net/ 上运行 token 但找不到 scp/scope 部分时得到的结果。

以下是我为该应用授予的权限(目前为所有权限)。

Microsoft Graph - 应用程序权限:18 - 委派权限:40 Windows Azure Active Directory - 应用程序权限:4 - 委派权限:8 Office 365 Exchange Online -应用程序权限:9 - 委派权限:30

Answer 1

I've already gave the app all permissions (delegate and app permissions) that are necessary.

情况可能并非如此:)。通常，403 禁止表示您的 token 不具备您调用的 API 所需的范围(在 scp 声明中)。简单的查找方法:在调试器中获取 token (它是一个很大的长 Base64 字符串)，然后转到 http://jwt.calebb.net/并将其粘贴进去。您将看到它被解码为 JSON Web token 。查找 roles 声明:

roles: [
  "Calendars.Read",
  "Mail.Read",
  "Contacts.Read" 
],

如果您没有 Mail.Read 或 Mail.ReadWrite，则您没有配置必要的权限。
