request help: how does the consumer work？

[soulbird]

Issue description

s described in the documentation
creates a consumer object：

curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "username": "jack",
    "plugins": {
        "key-auth": {
            "key": "auth-one"
        }
    }
}'

creates a route or service object

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

From the created parameters, I didn't find any related parameters between consumer and route.
The processing of the request in my understanding is:

1、recvive a request
2、match router
3、find related consumer obj
4、load plugins

Is that so？ And how does the consumer work？Each consumer object does not have a unique representation, how is step three done?

Environment

• apisix version (cmd: apisix version):
• OS (cmd: uname -a):
• OpenResty / Nginx version (cmd: nginx -V or openresty -V):
• etcd version, if have (cmd: run curl http://127.0.0.1:9090/v1/server_info to get the info from server-info API):
• apisix-dashboard version, if have:
• the plugin runner version, if the issue is about a plugin runner (cmd: depended on the kind of runner):
• luarocks version, if the issue is about installation (cmd: luarocks --version):

@soulbird APISIX find consumers according to some plugins written in the Route (like auth plugins).
