Hi Sunil,
Thank you very much! Let me see if I understand the publish/subscribe
mechanism:
1. First, the publisher create one topic like below:
POST http(s)://{HOST:PORT}/topics/create Content-Type:
application/json
{
“topicName”:”com.abc.dmaap.mr.topicname”,
”description”:”This is a SAPTopic “,
“partitionCount”:”1”,
”replicationCount”:”3”,
”transactionEnabled”:”true”
}
2. Second, the publisher publish this topic out like below:
POST http(s)://{HOST:PORT}/events/com.abc.dmaap.mr.topicname
Content-Type: application/json (Does this step have a HTTP body?)
3.Last, the subscriber subscribe this topic like below:
GET
http(s)://{HOST:PORT}}/events/{topicname}/{consumegroup}/{consumerid}/{timeout=x}
Content-Type: application/json
(Also, does this step have a HTTP body? And the
{consumegroup} should be de defined somewhere before these three steps?)
It seems that this mechanism only allows the publisher to give the
subscriber a notification event without transmitting data. For example, the
publisher
tell the subscriber I get a bread, but not tell its brand, price, taste etc.
Plz correct me if my understanding is wrong, Sunil.
Thanks,
Wang

Hi Wang,
Subscribers can subscribe to a topic by hitting the Message Router endpoint .
Please refer the readthedocs for more details.
GET
http(s)://{HOST:PORT}}/events/{topicname}/{consumegroup}/{consumerid}/{timeout=x}

Subject: [onap-discuss] How to use Dmaap to subscribe notification
Hi, Ram
Sorry to bother you. I just want to consult you how to use Dmaap to
subscribe notifications? for example the SDNC want to subscribe notification
which the ESR published. Do you have a demo?
thanks
