Introduction

The consumer-restriction makes corresponding access restrictions based on different objects selected.

Attributes

Name	Type	Requirement	Default	Valid	Description
type	string	optional	consumer_name	["consumer_name", "service_id"]	According to different objects, corresponding restrictions, support consumer_name, service_id.
whitelist	array[string]	required			Choose one of the two with blacklist, only whitelist or blacklist can be enabled separately, and the two cannot be used together.
blacklist	array[string]	required			Choose one of the two with whitelist, only whitelist or blacklist can be enabled separately, and the two cannot be used together.
rejected_code	integer	optional	403	[200,...]	The HTTP status code returned when the request is rejected.

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"            ]        }    }}'

Requests from jack2:

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

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"}'

2. 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        }    }}'

3. 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' -iHTTP/1.1 200 OK...

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

4. 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' -iHTTP/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.
