## 如何开启

1. 下面例子展示了如何为指定路由开启 `tcp-logger` 插件的。

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

## 测试插件

* 成功的情况:

```shell
$ curl -i http://127.0.0.1:9080/hello
HTTP/1.1 200 OK
...
hello, world
```

## 禁用插件


想要禁用“tcp-logger”插件，是非常简单的，将对应的插件配置从json配置删除，就会立即生效，不需要重新启动服务：

```shell
$ curl http://127.0.0.1:2379/apisix/admin/routes/1 -X PUT -d value='
{
    "methods": ["GET"],
    "uri": "/hello",
    "plugins": {},
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    }
}'
```
