## API
|
|
|
|
This plugin will add `/apisix/plugin/jwt/sign` to sign.
|
|
You may need to use [interceptors](../plugin-interceptors.md) to protect it.
|
|
|
|
## How To Enable
|
|
|
|
1. set a consumer and config the value of the `jwt-auth` option
|
|
|
|
```shell
|
|
curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
|
{
|
|
"username": "jack",
|
|
"plugins": {
|
|
"jwt-auth": {
|
|
"key": "user-key",
|
|
"secret": "my-secret-key"
|
|
}
|
|
}
|
|
}'
|
|
```
|
|
|
|
`jwt-auth` uses the `HS256` algorithm by default, and if you use the `RS256` algorithm, you need to specify the algorithm and configure the public key and private key, as follows:
|
|
|
|
```shell
|
|
curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
|
{
|
|
"username": "kerouac",
|
|
"plugins": {
|
|
"jwt-auth": {
|
|
"key": "user-key",
|
|
"public_key": "-----BEGIN PUBLIC KEY-----\n……\n-----END PUBLIC KEY-----",
|
|
"private_key": "-----BEGIN RSA PRIVATE KEY-----\n……\n-----END RSA PRIVATE KEY-----",
|
|
"algorithm": "RS256"
|
|
}
|
|
}
|
|
}'
|
|
```
|
|
|
|
you can visit Dashboard `http://127.0.0.1:9080/apisix/dashboard/` and add a Consumer through the web console:
|
|
|
|
|
|
|
|
then add jwt-auth plugin in the Consumer page:
|
|
|
|
|
|
2. add a Route or add a Service, and enable the `jwt-auth` plugin
|
|
|
|
```shell
|
|
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
|
{
|
|
"methods": ["GET"],
|
|
"uri": "/index.html",
|
|
"plugins": {
|
|
"jwt-auth": {}
|
|
},
|
|
"upstream": {
|
|
"type": "roundrobin",
|
|
"nodes": {
|
|
"39.97.63.215:80": 1
|
|
}
|
|
}
|
|
}'
|
|
```
|
|
|
