key-auth

Description#

The key-auth Plugin is used to add an authentication key (API key) to a Route or a Service.

This works well with a Consumer. Consumers of the API can then add their key to the query string or the header to authenticate their requests.

Attributes#

For Consumer:

NameTypeRequirementDescription
keystringrequiredUnique key for a Consumer.

For Route:

NameTypeRequirementDefaultValidDescription
headerstringoptionalapikeyThe header to get the key from.
querystringoptionalapikeyThe query string to get the key from. Lower priority than header.
hide_credentialsbooloptionalfalseApache APISIX will pass the request header or query string that contains the authentication information to the Upstream if hide_credentials is false. Otherwise the authentication information will be removed before proxying.

Enabling the Plugin#

To enable the Plugin, you have to create a Consumer object with an authentication key and configure your Route to authenticate requests.

First you can create a Consumer object through the Admin API with a unique key:

curl http://127.0.0.1:9180/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"username": "jack",
"plugins": {
"key-auth": {
"key": "auth-one"
}
}
}'

You can also use the APISIX Dashboard to complete the operation through a web UI.

First, create a Consumer object:

You can then add the key-auth Plugin:

Once you have created a Consumer object, you can then configure a Route or a Service to authenticate requests:

curl http://127.0.0.1:9180/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
}
}
}'

To fetch the key from a different header than apikey, change the header in the configuration:

{
"key-auth": {
"header": "Authorization"
}
}

Example usage#

After you have configured the Plugin as mentioned above, you can make a request as shown:

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

And if the request has a missing key or a wrong key:

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#

To disable the key-auth Plugin, you can delete the corresponding JSON configuration from the Plugin configuration. APISIX will automatically reload and you do not have to restart for this to take effect.

curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"uri": "/index.html",
"plugins": {},
"upstream": {
"type": "roundrobin",
"nodes": {
"127.0.0.1:1980": 1
}
}
}'
