```shell
|
2020-11-24 16:51:47 +08:00
|
|
|
|
$ curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '

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

|
|
"type": "roundrobin",
|
|
|
|
|
|
"nodes": {
|
|
|
|
|
|
"127.0.0.1:1980": 1
|
|
|
|
|
|
}
