使用msgraph-sdk-java实现组$filter查询

基础概念

Microsoft Graph SDK for Java 是一个用于与 Microsoft Graph API 进行交互的库。Microsoft Graph API 提供了一个统一的接口来访问 Microsoft 365 服务的数据，如 Office 365、Azure Active Directory 等。$filter 查询参数用于在请求中过滤结果，以便只返回满足特定条件的对象。

类型与应用场景

类型：$filter 支持多种比较操作符（如 eq, ne, gt, lt 等）和逻辑操作符（如 and, or）。
应用场景：适用于需要从大量数据中筛选出特定记录的场景，如用户管理、邮件筛选、日历事件查询等。

示例代码

以下是一个使用 msgraph-sdk-java 实现组 $filter 查询的示例代码：

import com.microsoft.graph.auth.enums.NationalCloud;
import com.microsoft.graph.core.ClientException;
import com.microsoft.graph.models.extensions.Group;
import com.microsoft.graph.requests.extensions.IGroupCollectionPage;
import com.microsoft.graph.requests.extensions.GraphServiceClient;
import com.microsoft.identity.client.AuthenticationResult;
import com.microsoft.identity.client.IAuthenticationResult;
import com.microsoft.identity.client.ISingleAccountPublicClientApplication;
import com.microsoft.identity.client.PublicClientApplication;

public class GroupFilterExample {
    private static final String CLIENT_ID = "YOUR_CLIENT_ID";
    private static final String[] SCOPES = {"https://graph.microsoft.com/.default"};

    public static void main(String[] args) {
        try {
            ISingleAccountPublicClientApplication app = PublicClientApplication.builder(CLIENT_ID)
                    .authority("https://login.microsoftonline.com/YOUR_TENANT_ID")
                    .build();

            IAuthenticationResult result = app.acquireToken(new PublicClientApplication.AcquireTokenParameters.Builder()
                    .scopes(SCOPES)
                    .build())
                    .get();

            GraphServiceClient graphClient = GraphServiceClient.builder()
                    .authenticationProvider(new IAuthenticationProvider() {
                        @Override
                        public void authenticateRequest(IHttpRequest request) {
                            request.addHeader("Authorization", "Bearer " + result.accessToken());
                        }
                    })
                    .buildClient();

            IGroupCollectionPage groups = graphClient.groups()
                    .buildRequest()
                    .filter("displayName eq 'Developers'")
                    .get();

            for (Group group : groups.getCurrentPage()) {
                System.out.println(group.displayName);
            }
        } catch (ClientException | InterruptedException | ExecutionException e) {
            e.printStackTrace();
        }
    }
}
