curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
|
{
|
|
"username": "foo",
|
|
"plugins": {
|
|
"plugins": {
|
|
"syslog": {
|
|
"host" : "127.0.0.1",
|
|
"port" : 5044,
|
|
"flush_limit" : 1
|
|
}
|
|
},
|
|
"upstream": {
|
|
"type": "roundrobin",
|
|
"nodes": {
|
|
"127.0.0.1:1980": 1
|
|
}
|
|
},
|
|
"uri": "/hello"
|
|
}
|

* success:
|
|
|
|
```shell
|
|
$ curl -i http://127.0.0.1:9080/hello
|
|
HTTP/1.1 200 OK

|
|
"methods": ["GET"],
|
|
"uri": "/hello",
|
|
"plugins": {},
|
|
"upstream": {
|
|
"type": "roundrobin",
