## 描述
`tencent-cloud-cls` 插件可用于将 APISIX 日志使用[腾讯云日志服务](https://cloud.tencent.com/document/product/614) API 推送到您的日志主题。
## 属性
| 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 |
| ----------------- | ------- | ------ |-------| ------------ |------------------------------------------------------------------------------|
| cls_host | string | | | | CLS API 域名,参考[使用 API 上传日志](https://cloud.tencent.com/document/api/614/16873)。|
| cls_topic | string | | | | CLS 日志主题 id |
| secret_id | string | | | | API 密钥的 id |
| secret_key | string | | | | API 密钥的 key |
| sample_ratio | number | | 1 | [0.00001, 1] | 采样的比例。设置为 `1` 时,将对所有请求进行采样。 |
| include_req_body | boolean | | false | [false, true]| 当设置为 `true` 时,日志中将包含请求体。 |
| include_resp_body | boolean | | false | [false, true]| 当设置为 `true` 时,日志中将包含响应体。 |
| global_tag | object | | | | kv 形式的 JSON 数据,可以写入每一条日志,便于在 CLS 中检索。 |
注意:schema 中还定义了 `encrypt_fields = {"secret_key"}`,这意味着该字段将会被加密存储在 etcd 中。具体参考 [加密存储字段](../plugin-develop.md#加密存储字段)。
该插件支持使用批处理器来聚合并批量处理条目(日志/数据)。这样可以避免插件频繁地提交数据,默认情况下批处理器每 `5` 秒钟或队列中的数据达到 `1000` 条时提交数据,如需了解批处理器相关参数设置,请参考 [Batch-Processor](../batch-processor.md#配置)。
## 插件元数据
| 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 |
| ---------------- | ------- | ------ | ------------- | ------- | ------------------------------------------------ |
| log_format | object | | {"host": "$host", "@timestamp": "$time_iso8601", "client_ip": "$remote_addr"} | | JSON 格式的键值对来声明日志格式。对于值部分,仅支持字符串。如果是以 `$` 开头。则表明获取 [APISIX 变量](../../../en/latest/apisix-variable.md) [NGINX 内置变量](http://nginx.org/en/docs/varindex.html)。 |
:::info 重要
该设置全局生效。如果指定了 `log_format`,则所有绑定 `tencent-cloud-cls` 的路由或服务都将使用该日志格式。
:::
以下示例展示了如何通过 Admin API 配置插件元数据:
```shell
curl http://127.0.0.1:9180/apisix/admin/plugin_metadata/tencent-cloud-cls \
-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"log_format": {
"host": "$host",
"@timestamp": "$time_iso8601",
"client_ip": "$remote_addr"
}
}'
```
配置完成后,你将在日志系统中看到如下类似日志:
```shell
{"host":"localhost","@timestamp":"2020-09-23T19:05:05-04:00","client_ip":"127.0.0.1","route_id":"1"}
{"host":"localhost","@timestamp":"2020-09-23T19:05:05-04:00","client_ip":"127.0.0.1","route_id":"1"}
```
## 启用插件
你可以通过以下命令在指定路由中启用该插件:
```shell
curl http://127.0.0.1:9180/apisix/admin/routes/1 \
-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"plugins": {
"tencent-cloud-cls": {
"cls_host": "ap-guangzhou.cls.tencentyun.com",
"cls_topic": "${your CLS topic name}",
"global_tag": {
"module": "cls-logger",
"server_name": "YourApiGateWay"
},
"include_req_body": true,
"include_resp_body": true,
"secret_id": "${your secret id}",
"secret_key": "${your secret key}"
}
},
"upstream": {
"type": "roundrobin",
"nodes": {
"127.0.0.1:1980": 1
}
},
"uri": "/hello"
}'
```
## 测试插件
现在你可以向 APISIX 发起请求:
```shell
curl -i http://127.0.0.1:9080/hello
```
```
HTTP/1.1 200 OK
...
hello, world
```
## 禁用插件
当你需要禁用该插件时,可通过以下命令删除相应的 JSON 配置,APISIX 将会自动重新加载相关配置,无需重启服务:
```shell
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
}
}
}'
```
