嗨，我在为 ALB 侦听器设置多个证书时遇到问题。这是我的 CF 模板的片段：

  DiscoveryListenerHTTPS:
    Type: AWS::ElasticLoadBalancingV2::Listener
    DependsOn:
      - DiscoveryLoadBalancer
      - DiscoveryLoadBalancerTargetGroup
    Properties:
      Certificates:
       - CertificateArn: !Ref CertificateArn1
       - CertificateArn: !Ref CertificateArn2

和回应是： Up to '1' certificate ARNs can be specified, but '2' were specified (Service: AmazonElasticLoadBalancingV2; Status Code: 400; Error Code: TooManyCertificates; Request ID: XXXXXXXXX)

是否可以按顺序使用logstash过滤器？例如，我想将消息解析为 json，然后按字符拆分新创建的字段。

输入 => 过滤器 => 过滤器 => 输出 => 弹性搜索

当括号中有两个值时为什么会String.matches返回？true[]

System.out.println("[one]".matches("(?i).*" + "[two]" + ".*"));
   //Why does it return true? Shouldn't "[]" be treated as value?
System.out.println("one".matches("(?i).*" + "two" + ".*"));//OK - prints false

System.out.println("[one]".equals("[two]"));//OK - prints false
System.out.println("one".equals("two"));//OK - prints false
