用 PullLogsResponse，LogGroupData，Logs.LogGroup如何获取_

要使用Java代码通过PullLogsResponse获取日志中的__receive_time__标签，您可以参考以下示例代码：
java import com.aliyun.openservices.log.Client; import com.aliyun.openservices.log.request.PullLogsRequest; import com.aliyun.openservices.log.response.PullLogsResponse; import com.aliyun.openservices.log.common.QueriedLog; import com.aliyun.openservices.log.common.LogItem; public class RetrieveReceiveTimeFromLogs { public static void main(String[] args) { // 初始化Client等操作... String project = "YourProjectName"; String logstore = "YourLogstoreName"; String topic = ""; // 或指定主题 long fromTime = 1609459200L; // 查询起始时间戳，例如2021-01-01 00:00:00 long toTime = System.currentTimeMillis() / 1000; // 查询结束时间戳，例如当前时间 PullLogsRequest request = new PullLogsRequest(project, logstore, topic, fromTime, toTime); PullLogsResponse response = client.pullLogs(request); for (QueriedLog log : response.getLogs()) { LogItem item = log.GetLogItem(); String receiveTime = item.GetTag("__receive_time__"); if (receiveTime != null) { System.out.println("Log Receive Time: " + receiveTime); } } } }
这段代码展示了如何设置PullLogsRequest来从指定的日志项目和日志存储中拉取日志数据，然后遍历PullLogsResponse中的每条日志，使用LogItem的GetTag方法获取__receive_time__标签的值并打印出来。请根据实际需求调整项目名称、日志存储名称及时间范围。
