| ## 描述 |
| |
| `http-logger` 是一个插件,可将 Log 数据请求推送到 HTTP / HTTPS 服务器。 |
| |
| 这将提供将 Log 数据请求作为 JSON 对象发送到监视工具和其他 HTTP 服务器的功能。 |
| |
| ## 属性 |
| |
| | 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 | |
| | ---------------- | ------- | ------ | ------------- | ------- | ------------------------------------------------ | |
| | uri | string | 必须 | | | `HTTP/HTTPS` 服务器的 URI。 | |
| | auth_header | string | 可选 | "" | | 授权头部。 | |
| | timeout | integer | 可选 | 3 | [1,...] | 发送请求后保持连接活动的时间。 | |
| | name | string | 可选 | "http logger" | | 标识 logger 的唯一标识符。 | |
| | include_req_body | boolean | 可选 | false | [false, true] | 是否包括请求 body。false: 表示不包含请求的 body ; true: 表示包含请求的 body 。 | |
| | include_resp_body| boolean | 可选 | false | [false, true] | 是否包括响应体。包含响应体,当为`true`。 | |
| | include_resp_body_expr | array | 可选 | | | 是否采集响体,基于 [lua-resty-expr](https://github.com/api7/lua-resty-expr)。 该选项需要开启 `include_resp_body`| |
| | concat_method | string | 可选 | "json" | ["json", "new_line"] | 枚举类型: `json`、`new_line`。**json**: 对所有待发日志使用 `json.encode` 编码。**new_line**: 对每一条待发日志单独使用 `json.encode` 编码并使用 "\n" 连接起来。 | |
| | ssl_verify | boolean | optional | false | [false, true] | 是否验证证书。 | |
| |
| 本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,默认设置情况下批处理器会每 `5` 秒钟或队列中的数据达到 `1000` 条时提交数据,如需了解或自定义批处理器相关参数设置,请参考 [Batch-Processor](../batch-processor.md#配置) 配置部分。 |
| |
| ## 如何开启 |
| |
| 这是有关如何为特定路由启用 `http-logger` 插件的示例。你可以在 [mockbin](http://mockbin.org/bin/create) 生成一个模拟 HTTP 服务器来浏览生成的日志 |
| |
| ```shell |
| curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' |
| { |
| "plugins": { |
| "http-logger": { |
| "uri": "http://mockbin.org/bin/:ID" |
| } |
| }, |
| "upstream": { |
| "type": "roundrobin", |
| "nodes": { |
| "127.0.0.1:1980": 1 |
| } |
| }, |
| "uri": "/hello" |
| }' |
| ``` |
| |
| ## 测试插件 |
| |
| > 成功: |
| |
| ```shell |
| $ curl -i http://127.0.0.1:9080/hello |
| HTTP/1.1 200 OK |
| ... |
| hello, world |
| ``` |
| |
| ## 插件元数据设置 |
| |
| | 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 | |
| | ---------------- | ------- | ------ | ------------- | ------- | ------------------------------------------------ | |
| | log_format | object | 可选 | {"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,则表明是要获取 [APISIX 变量](../../../en/latest/apisix-variable.md) 或 [Nginx 内置变量](http://nginx.org/en/docs/varindex.html)。特别的,**该设置是全局生效的**,意味着指定 log_format 后,将对所有绑定 http-logger 的 Route 或 Service 生效。 | |
| |
| ### 设置日志格式示例 |
| |
| ```shell |
| curl http://127.0.0.1:9080/apisix/admin/plugin_metadata/http-logger -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' |
| { |
| "log_format": { |
| "host": "$host", |
| "@timestamp": "$time_iso8601", |
| "client_ip": "$remote_addr" |
| } |
| }' |
| ``` |
| |
| 在日志收集处,将得到类似下面的日志: |
| |
| ```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"} |
| ``` |
| |
| ## 禁用插件 |
| |
| 在插件配置中删除相应的 json 配置以禁用 http-logger。APISIX 插件是热重载的,因此无需重新启动 APISIX: |
| |
| ```shell |
| $ curl http://127.0.0.1:9080/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 |
| } |
| } |
| }' |
| ``` |
