## 定义

`sls-logger` 是使用[RF5424](https://tools.ietf.org/html/rfc5424)标准将日志数据发送到以JSON格式发送到[阿里云日志服务](https://help.aliyun.com/document_detail/112903.html?spm=a2c4g.11186623.6.763.21321b47wcwt1u)。

该插件提供了将Log Data作为批处理推送到阿里云日志服务器的功能。如果您没有收到日志数据，请放心一些时间，它会在我们的批处理处理器中的计时器功能到期后自动发送日志。

有关Apache APISIX中Batch-Processor的更多信息，请参考：
[Batch-Processor](../batch-processor.md)

## 如何开启

1. 下面例子展示了如何为指定路由开启 `sls-logger` 插件的。

```shell
curl http://127.0.0.1:9080/apisix/admin/routes/5 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "plugins": {
        "sls-logger": {
            "host": "100.100.99.135",
            "port": 10009,
            "project": "your_project",
            "logstore": "your_logstore",
            "access_key_id": "your_access_key_id",
            "access_key_secret": "your_access_key_secret",
            "timeout": 30000
        }
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    },
    "uri": "/hello"
}'
```

```
注释:这里的 100.100.99.135 是阿里云华北3内外地址。
```

* 成功的情况:

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

## 禁用插件

想要禁用“sls-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://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d value='
{
    "uri": "/hello",
    "plugins": {},
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    }
}'
```
