Development with Service-Center¶
This chapter is about how to implement the feature of micro-service discovery with ServiceCenter, and you can get more detail at here
Micro-service registration¶
curl -X POST \
http://127.0.0.1:30100/v4/default/registry/microservices \
-H 'content-type: application/json' \
-H 'x-domain-name: default' \
-d '{
"service":
{
"appId": "default",
"serviceName": "DemoService",
"version":"1.0.0"
}
}'
and then you can get the ‘DemoService’ ID like below:
{
"serviceId": "a3fae679211211e8a831286ed488fc1b"
}
Instance registration¶
mark down the micro-service ID and call the instance registration API, according to the ServiceCenter definition: One process should be registered as one instance
curl -X POST \
http://127.0.0.1:30100/v4/default/registry/microservices/a3fae679211211e8a831286ed488fc1b/instances \
-H 'content-type: application/json' \
-H 'x-domain-name: default' \
-d '{
"instance":
{
"hostName":"demo-pc",
"endpoints": [
"rest://127.0.0.1:8080"
]
}
}'
the successful response like below:
{
"instanceId": "288ad703211311e8a831286ed488fc1b"
}
if all are successful, it means you have completed the micro-service registration and instance publish
Discovery¶
the next step is that discovery the micro-service instance by service name and version rule
curl -X GET \
'http://127.0.0.1:30100/v4/default/registry/instances?appId=default&serviceName=DemoService&version=latest' \
-H 'content-type: application/json' \
-H 'x-consumerid: a3fae679211211e8a831286ed488fc1b' \
-H 'x-domain-name: default'
here, you can get the information from the response
{
"instances": [
{
"instanceId": "b4c9e57f211311e8a831286ed488fc1b",
"serviceId": "a3fae679211211e8a831286ed488fc1b",
"version": "1.0.0",
"hostName": "demo-pc",
"endpoints": [
"rest://127.0.0.1:8080"
],
"status": "UP",
"healthCheck": {
"mode": "push",
"interval": 30,
"times": 3
},
"timestamp": "1520322915",
"modTimestamp": "1520322915"
}
]
}
