HTTPS上的可携式调度事件消息

Question

我配置了一个Knative触发器。事件应由通过HTTPS运行的服务来处理。

apiVersion: eventing.knative.dev/v1
kind: Trigger
metadata:
name: my-trigger
namespace: my-ns
spec:
broker: my-broker
filter:
attributes:
type: dev.knative.sources.ping
subscriber:
ref:
apiVersion: v1
kind: Service
namespace: event-handler-ns
name: event-handler-service
uri: /handle/event
---
kind: Service
apiVersion: v1
metadata:
name: event-handler-service
namespace: event-handler-ns
spec:
selector:
app: event-handler
ports:
- protocol: TCP
port: 443
targetPort: 8443

如果我查看代理过滤器的日志，我可以看到事件是通过HTTP发送的。我找不到任何关于如何通过HTTPS进行POST的文档。我能找到的唯一文档是将knative服务配置为在HTTPS上运行(而不是我的负责事件处理的自定义服务(。

}

是否可以在触发器中为订阅者指定协议？

Answer 1

uri可以是一个绝对URL，具有非空方案和指向目标的非空主机(或相对URI(。从文档

因此，当只使用uri:时，您应该能够指定协议

subscriber:
uri: https://event-handler-service.event-handler-ns/handle/event

Answer 2

正确，URI可以是HTTPS端点，但实际实现取决于broker中的dispatcher代码。通常，它通过提供自定义TLS证书(如果有的话(来工作，类似于tag解析的这种方法。

您正在使用哪种broker？
