Service

A Service is an abstraction of an API (which can also be understood as a set of Route abstractions). It usually corresponds to the upstream service abstraction. Between Route and Service, usually the relationship of N:1, please see the following image.

Different Route rules are bound to a Service at the same time. These Routes will have the same upstream and plugin configuration, reducing redundant configuration.

The following example creates a Service that enables the current-limit plugin, and then binds the Route with the id of 100 and 101 to the Service.

# create new Service$ curl http://127.0.0.1:9080/apisix/admin/services/200 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{    "plugins": {        "limit-count": {            "count": 2,            "time_window": 60,            "rejected_code": 503,            "key": "remote_addr"        }    },    "upstream": {        "type": "roundrobin",        "nodes": {            "127.0.0.1:1980": 1        }    }}'
# create new Route and reference the service by id `200`curl http://127.0.0.1:9080/apisix/admin/routes/100 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{    "methods": ["GET"],    "uri": "/index.html",    "service_id": "200"}'
curl http://127.0.0.1:9080/apisix/admin/routes/101 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{    "methods": ["GET"],    "uri": "/foo/index.html",    "service_id": "200"}'

Of course, we can also specify different plugin parameters or upstream for Route. Some of the following Routes have different current-limit parameters. Other parts (such as upstream) continue to use the configuration parameters in Service.

curl http://127.0.0.1:9080/apisix/admin/routes/102 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{    "uri": "/bar/index.html",    "id": "102",    "service_id": "200",    "plugins": {        "limit-count": {            "count": 2000,            "time_window": 60,            "rejected_code": 503,            "key": "remote_addr"        }    }}'

Note: When both Route and Service enable the same plugin, the Route parameter has a higher priority than Service.
