| ## 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 | 是 | | | CLS API 域名,参考[使用 API 上传日志](https://cloud.tencent.com/document/api/614/16873)。| |
| | cls_topic | string | 是 | | | CLS 日志主题 id。 | |
| | secret_id | string | 是 | | | 云 API 密钥的 id。 | |
| | secret_key | string | 是 | | | 云 API 密钥的 key。 | |
| | sample_ratio | number | 否 | 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 | 否 | false | [false, true]| 当设置为 `true` 时,日志中将包含请求体。 | |
| | include_resp_body | boolean | 否 | false | [false, true]| 当设置为 `true` 时,日志中将包含响应体。 | |
| | global_tag | object | 否 | | | 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 | 否 | {"host": "$host", "@timestamp": "$time_iso8601", "client_ip": "$remote_addr"} | | 以 JSON 格式的键值对来声明日志格式。对于值部分,仅支持字符串。如果是以 `$` 开头。则表明获取 [APISIX 变量](../../../en/latest/apisix-variable.md) 或 [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 |
| } |
| } |
| }' |
| ``` |
