Java使用现有的GraphClient (5.13.0版本)获取AccessToken

Question

我们的前端使用PKCE流并获取访问令牌。按照旧的实现(microsoft-graph@2.8.1版本)，下面的代码段使用现有的访问令牌获取Graph。现在，我无法在新的中完成同样的工作。

IGraphServiceClient client = GraphServiceClient.builder()
                        .authenticationProvider( request -> request.addHeader("Authorization", "Bearer " + tokenAuthentication.getToken().getTokenValue()) )
                        .buildClient(); 

已添加到项目中的依赖项

<dependency>
            <!-- Include the sdk as a dependency -->
            <groupId>com.microsoft.graph</groupId>
            <artifactId>microsoft-graph</artifactId>
            <version>5.13.0</version>
        </dependency>

终于起作用了..。见下文片段..。

IAuthenticationProvider authProvider = new IAuthenticationProvider() {
            
            @Override
            public CompletableFuture<String> getAuthorizationTokenAsync(URL requestUrl) {
                CompletableFuture<String> future = new CompletableFuture<>();
                future.complete(yourToken);
                return future;
            }
        };
        
        GraphServiceClient<Request> graphClient = GraphServiceClient
                .builder()
                .authenticationProvider(authProvider)
                .buildClient();

         return graphClient.me().buildRequest().get();
