How To Enable

Two steps are required:

  1. creates a consumer object, and set the attributes of plugin key-auth.
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"
        }
    }
}'

You can open dashboard with a browser: http://127.0.0.1:9080/apisix/dashboard/, to complete the above operation through the web interface, first add a route:

Then add key-auth plugin:

  1. creates a route or service object, and enable plugin key-auth.
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": {
            "39.97.63.215:80": 1
        }
    }
}'

Test Plugin

Here is a correct test example:

$ curl http://127.0.0.2:9080/index.html -H 'apikey: auth-one' -i
HTTP/1.1 200 OK
...

If the request does not set apikey correctly, will get a 401 response.

$ curl http://127.0.0.2:9080/index.html -i
HTTP/1.1 401 Unauthorized
...
{"message":"Missing API key found in request"}

$ curl http://127.0.0.2:9080/index.html -H 'apikey: abcabcabc' -i
HTTP/1.1 401 Unauthorized
...
{"message":"Invalid API key in request"}

Disable Plugin

When you want to disable the key-auth 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://127.0.0.1:2379/v2/keys/apisix/routes/1 -X PUT -d value='
{
    "uri": "/index.html",
    "plugins": {},
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "39.97.63.215:80": 1
        }
    }
}'

The key-auth plugin has been disabled now. It works for other plugins.
