在Java中使用Oauth Graph Service Client API检索Office 365邮件文件附件,可以按照以下步骤进行操作:
import com.microsoft.aad.msal4j.*;
public class AuthProvider {
private static final String CLIENT_ID = "your_client_id";
private static final String CLIENT_SECRET = "your_client_secret";
private static final String AUTHORITY = "https://login.microsoftonline.com/your_tenant_id";
private static ConfidentialClientApplication app;
public static IAuthenticationResult getAccessToken() throws Exception {
if (app == null) {
app = ConfidentialClientApplication.builder(CLIENT_ID, ClientCredentialFactory.createFromSecret(CLIENT_SECRET))
.authority(AUTHORITY)
.build();
}
String[] scopes = {"https://graph.microsoft.com/.default"};
ClientCredentialParameters parameters = ClientCredentialParameters.builder(scopes).build();
return app.acquireToken(parameters).join();
}
}
import com.microsoft.graph.authentication.IAuthenticationProvider;
import com.microsoft.graph.requests.GraphServiceClient;
import com.microsoft.graph.requests.MessageCollectionPage;
import com.microsoft.graph.models.Message;
public class GraphService {
public static void main(String[] args) {
IAuthenticationProvider authProvider = new IAuthenticationProvider() {
@Override
public void authenticateRequest(RequestInfo requestInfo) {
try {
IAuthenticationResult result = AuthProvider.getAccessToken();
requestInfo.addHeader("Authorization", "Bearer " + result.accessToken());
} catch (Exception e) {
e.printStackTrace();
}
}
};
GraphServiceClient<Request> graphClient = GraphServiceClient.builder().authenticationProvider(authProvider).buildClient();
MessageCollectionPage messages = graphClient.me().messages().buildRequest().get();
for (Message message : messages.getCurrentPage()) {
// 处理邮件附件
// 可以使用message.attachments().buildRequest().get()来获取附件列表
}
}
}
请注意,上述代码仅为示例,实际使用时需要根据具体情况进行适当的修改和错误处理。
