whitelist array[string] required Grant full access to all users specified in the provided list , has the priority over allowed_by_methods
blacklist array[string] required Reject connection to all users specified in the provided list , has the priority over whitelist
rejected_code integer optional 403 [200,...] The HTTP status code returned when the request is rejected.
rejected_msg string optional The message returned when the request is rejected.
allowed_by_methods array[object] optional Set a list of allowed HTTP methods for the selected user , HTTP methods can be ["GET", "POST", "PUT", "DELETE", "PATCH", "HEAD", "OPTIONS", "CONNECT", "TRACE"]

For the type field is an enumerated type, it can be consumer_name or service_id. They stand for the following meanings:

  • consumer_name: Add the username of consumer to a whitelist or blacklist (supporting single or multiple consumers) to restrict access to services or routes.
  • service_id: Add the id of the service to a whitelist or blacklist (supporting one or more services) to restrict access to the service. It needs to be used in conjunction with authorized plugins.

Example

How to restrict consumer_name

The following is an example. The consumer-restriction plugin is enabled on the specified route to restrict consumer access.

curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
{
    "username": "jack1",
    "plugins": {
        "basic-auth": {
            "username":"jack2019",
            "password": "123456"
        }
    }
}'

curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
{
    "username": "jack2",
    "plugins": {
        "basic-auth": {
            "username":"jack2020",
            "password": "123456"
        }
    }
}'

curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/index.html",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    },
    "plugins": {
        "basic-auth": {},
        "consumer-restriction": {
            "whitelist": [
                "jack1"
            ]
        }
    }
}'

Test Plugin

Requests from jack1:

curl -u jack2019:123456 http://127.0.0.1:9080/index.html
HTTP/1.1 200 OK
...

Requests from jack2:

curl -u jack2020:123456 http://127.0.0.1:9080/index.html -i
HTTP/1.1 403 Forbidden
...
{"message":"The consumer_name is forbidden."}

How to restrict allowed_by_methods

This example restrict the user jack1 to only POST on the resource

curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/index.html",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    },
    "plugins": {
        "basic-auth": {},
        "consumer-restriction": {
            "allowed_by_methods":[{
                "user": "jack1",
                "methods": ["POST"]
            }]
        }
    }
}'

Test Plugin

Requests from jack1:

curl -u jack2019:123456 http://127.0.0.1:9080/index.html
HTTP/1.1 403 Forbidden
...
{"message":"The consumer_name is forbidden."}

Add the capability for jack1 to get the resource

curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/index.html",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    },
    "plugins": {
        "basic-auth": {},
        "consumer-restriction": {
            "allowed_by_methods":[{
                "user": "jack1",
                "methods": ["POST","GET"]
            }]
        }
    }
}'

Requests from jack1:

curl -u jack2019:123456 http://127.0.0.1:9080/index.html
HTTP/1.1 200 OK

How to restrict service_id

The service_id method needs to be used together with the authorization plug-in. Here, the key-auth authorization plug-in is taken as an example.

  1. Create two services.
curl http://127.0.0.1:9080/apisix/admin/services/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "upstream": {
        "nodes": {
            "127.0.0.1:1980": 1
        },
        "type": "roundrobin"
    },
    "desc": "new service 001"
}'

curl http://127.0.0.1:9080/apisix/admin/services/2 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "upstream": {
        "nodes": {
            "127.0.0.1:1980": 1
        },
        "type": "roundrobin"
    },
    "desc": "new service 002"
}'
  1. Bind the consumer-restriction plugin on the consumer (need to cooperate with an authorized plugin to bind), and add the service_id whitelist list.
curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "username": "new_consumer",
    "plugins": {
    "key-auth": {
        "key": "auth-jack"
    },
    "consumer-restriction": {
           "type": "service_id",
            "whitelist": [
                "1"
            ],
            "rejected_code": 403
        }
    }
}'
  1. Open the key-auth plugin on the route and bind the service_id to 1.
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/index.html",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    },
    "service_id": 1,
    "plugins": {
         "key-auth": {
        }
    }
}'

Test Plugin

curl http://127.0.0.1:9080/index.html -H 'apikey: auth-jack' -i
HTTP/1.1 200 OK
...

The service_id in the whitelist column allows access, and the plug-in configuration takes effect.

  1. Open the key-auth plugin on the route and bind the service_id to 2.
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/index.html",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    },
    "service_id": 2,
    "plugins": {
         "key-auth": {
        }
    }
}'

Test Plugin

curl http://127.0.0.1:9080/index.html -H 'apikey: auth-jack' -i
HTTP/1.1 403 Forbidden
...
{"message":"The service_id is forbidden."}

It means that the service_id that is not in the whitelist is denied access, and the plug-in configuration takes effect.

Disable Plugin

When you want to disable the consumer-restriction plugin, it is very simple, you can delete the corresponding json configuration in the plugin configuration, no need to restart the service, it will take effect immediately:

curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/index.html",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    },
    "plugins": {
        "basic-auth": {}
    }
}'

The consumer-restriction plugin has been disabled now. It works for other plugins.
