Credential

Description

Credential is the object that holds the Consumer credential configuration. A Consumer can use multiple credentials of different types. Credentials are used when you need to configure multiple credentials for a Consumer.

Currently, Credential can be configured with the authentication plugins basic-auth, hmac-auth, jwt-auth, and key-auth.

Configuration options

The fields for defining a Credential are defined as below.

Field	Required	Description
desc	False	Decriptiion of the Credential.
labels	False	Labels of the Credential.
plugins	False	The plugin configuration corresponding to Credential. For more information, see Plugins.

note

For more information about the Credential object, you can refer to the Admin API Credential resource guide.

Example

Consumer Example describes how to configure the auth plugin for Consumer and how to use it with other plugins. In this example, the Consumer has only one credential of type key-auth. Now suppose the user needs to configure multiple credentials for that Consumer, you can use Credential to support this.

note

You can fetch the admin_key from config.yaml and save to an environment variable with the following command:

admin_key=$(yq '.deployment.admin.admin_key[0].key' conf/config.yaml | sed 's/"//g')

1. Create the Consumer without specifying the auth plug-n, but use Credential to configure the auth plugin later.

   curl http://127.0.0.1:9180/apisix/admin/consumers \
   -H "X-API-KEY: $admin_key" -X PUT -d '
   {
       "username": "jack"
   }'

2. Create 2 key-auth Credentials for the Consumer.

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

   curl http://127.0.0.1:9180/apisix/admin/consumers/jack/key-auth-two \
   -H "X-API-KEY: $admin_key" -X PUT -d '
   {
       "plugins": {
           "key-auth": {
               "key": "auth-two"
           }
       }
   }'

3. Create a route and enable key-auth plugin on it.

   curl http://127.0.0.1:9180/apisix/admin/routes/1 \
   -H "X-API-KEY: $admin_key" -X PUT -d '
   {
       "plugins": {
           "key-auth": {}
       },
       "upstream": {
           "nodes": {
               "127.0.0.1:1980": 1
           },
           "type": "roundrobin"
       },
       "uri": "/hello"
   }'

4. Test.

Test the request with the auth-one and auth-two keys, and they both respond correctly.

```shell
curl http://127.0.0.1:9080/hello -H 'apikey: auth-one' -I
curl http://127.0.0.1:9080/hello -H 'apikey: auth-two' -I
```

Enable the limit-count plugin for the Consumer.

```shell
curl http://127.0.0.1:9180/apisix/admin/consumers \
-H "X-API-KEY: $admin_key" -X PUT -d '
{
    "username": "jack",
    "plugins": {
        "limit-count": {
            "count": 2,
            "time_window": 60,
            "rejected_code": 503,
            "key": "remote_addr"
        }
    }
}'
```

Requesting the route more than 3 times in a row with each of the two keys, the test returns 503 and the request is restricted.
