使用X-Ray SDK for Java或Node.js中提供的X-Ray Lambda扩展来正确捕获并传递父跟踪ID。

Java示例：

public class MyLambda implements RequestHandler, String> {
  static {
    AWSXRayRecorderBuilder builder = AWSXRayRecorderBuilder.standard().withPlugin(new AWSSDKPlugin());
    AWSXRay.setGlobalRecorder(builder.build());
  }

  public String handleRequest(Map event, Context context) {
    AWSXRay.beginSegment("MyLambdaSegment");
    Segment parent = AWSXRay.getCurrentSegment();
    try {
      // 基于父跟踪ID创建子段
      Subsegment subsegment = parent.addChild(Subsegment.builder().name("mySubsegment").build());
      subsegment.putMetadata("foo", "bar");
      // 执行子段代码
      // ...

      subSegment.close();
      return "Success!";
    } catch (Exception ex) {
      parent.addException(ex);
      throw ex;
    } finally {
      AWSXRay.endSegment();
    }
  }
}

Node.js示例：

const AWSXRay = require('aws-xray-sdk-core');

exports.handler = async (event, context) => {
  // 确保在Lambda绑定了X-Ray中间件
  AWSXRay.express.openSegment('MyLambdaSegment');
  const parent = AWSXRay.getSegment();

  try {
    const subsegment = parent.addNewSubsegment('mySubsegment');
    subsegment.addMetadata('foo', 'bar');

    // 执行子段代码
    // ...

    subsegment.close();
    AWSXRay.express.closeSegment();
    return 'Success!';
  } catch (ex) {
    parent.addError(ex);
    throw ex;
  } finally {
    AWSXRay.express.closeSegment();
  }
};
