| ## 描述 |
| |
| `http-logger` 插件可以将 APISIX 的日志数据推送到 HTTP 或 HTTPS 服务器。该插件提供了将日志数据请求作为 JSON 对象发送到监控工具或者其他 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 | 是 | | | HTTP 或 HTTPS 服务器的 URI。 | |
| | auth_header | string | 否 | | | 授权 header(如果需要)。 | |
| | timeout | integer | 否 | 3 | [1,...] | 发送请求后保持连接处于活动状态的时间。 | |
| | log_format | object | 否 | | | 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](../apisix-variable.md) 或 [NGINX 内置变量](http://nginx.org/en/docs/varindex.html)。 | |
| | include_req_body | boolean | 否 | false | [false, true] | 当设置为 `true` 时,将请求体包含在日志中。如果请求体太大而无法保存在内存中,由于 NGINX 的限制,无法记录。 | |
| | include_req_body_expr | array | 否 | | | 当 `include_req_body` 属性设置为 `true` 时的过滤器。只有当此处设置的表达式求值为 `true` 时,才会记录请求体。有关更多信息,请参阅 [lua-resty-expr](https://github.com/api7/lua-resty-expr) 。 | |
| | include_resp_body | boolean | 否 | false | [false, true] | 当设置为 `true` 时,包含响应体。 | |
| | include_resp_body_expr | array | 否 | | | 当 `include_resp_body` 属性设置为 `true` 时,使用该属性并基于 [lua-resty-expr](https://github.com/api7/lua-resty-expr) 进行过滤。如果存在,则仅在表达式计算结果为 `true` 时记录响应。 | |
| | concat_method | string | 否 | "json" | ["json", "new_line"] | 枚举类型: **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 | 否 | false | [false, true] | 当设置为 `true` 时验证证书。 | |
| |
| 该插件支持使用批处理器来聚合并批量处理条目(日志和数据)。这样可以避免该插件频繁地提交数据。默认情况下每 `5` 秒钟或队列中的数据达到 `1000` 条时,批处理器会自动提交数据,如需了解更多信息或自定义配置,请参考 [Batch Processor](../batch-processor.md#配置)。 |

| ### 默认日志格式示例 |
| |
| ```json |
| { |
| "service_id": "", |
| "apisix_latency": 100.99999809265, |
| "start_time": 1703907485819, |
| "latency": 101.99999809265, |
| "upstream_latency": 1, |
| "client_ip": "127.0.0.1", |
| "route_id": "1", |
| "server": { |
| "version": "3.7.0", |
| "hostname": "localhost" |
| }, |
| "request": { |
| "headers": { |
| "host": "127.0.0.1:1984", |
| "content-type": "application/x-www-form-urlencoded", |
| "user-agent": "lua-resty-http/0.16.1 (Lua) ngx_lua/10025", |
| "content-length": "12" |
| }, |
| "method": "POST", |
| "size": 194, |
| "url": "http://127.0.0.1:1984/hello?log_body=no", |
| "uri": "/hello?log_body=no", |
| "querystring": { |
| "log_body": "no" |
| } |
| }, |
| "response": { |
| "headers": { |
| "content-type": "text/plain", |
| "connection": "close", |
| "content-length": "12", |
| "server": "APISIX/3.7.0" |
| }, |

| "size": 123 |
| }, |
| "upstream": "127.0.0.1:1982" |
| } |
| ``` |
| |
| ## 插件元数据 |
| |
| | 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 | |
| | ---------------- | ------- | ------ | ------------- | ------- | ------------------------------------------------ | |
| | log_format | object | 否 | | | 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 `$` 开头。则表明获取 [APISIX 变量](../../../en/latest/apisix-variable.md) 或 [NGINX 内置变量](http://nginx.org/en/docs/varindex.html)。 | |
| |
| :::info 注意 |
| |
| 该设置全局生效。如果指定了 `log_format`,则所有绑定 `http-logger` 的路由或服务都将使用该日志格式。 |
| |
| ::: |
| |
| 以下示例展示了如何通过 Admin API 配置插件元数据: |
| |
| :::note |
| |
| 您可以这样从 `config.yaml` 中获取 `admin_key` 并存入环境变量: |
| |
| ```bash |
| admin_key=$(yq '.deployment.admin.admin_key[0].key' conf/config.yaml | sed 's/"//g') |
| ``` |
| |
| ::: |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/plugin_metadata/http-logger \ |
| -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "log_format": { |
| "host": "$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 |
| |
| 你可以通过如下命令在指定路由上启用 `http-logger` 插件: |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/routes/1 \ |
| -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "plugins": { |
| "http-logger": { |
| "uri": "http://mockbin.org/bin/:ID" |
| } |
| }, |
| "upstream": { |
| "type": "roundrobin", |
| "nodes": { |
| "127.0.0.1:1980": 1 |
| } |
| }, |
| "uri": "/hello" |
| }' |
| ``` |
| |
| [mockbin](http://mockbin.org/bin/create) 服务器用于模拟 HTTP 服务器,以方便查看 APISIX 生成的日志。 |
| |
| ## 测试插件 |
| |
| 你可以通过以下命令向 APISIX 发出请求,访问日志将记录在你的 `mockbin` 服务器中: |
| |
| ```shell |
| curl -i http://127.0.0.1:9080/hello |
| ``` |
| |
| ## 删除插件 |
| |
| 当你需要删除该插件时,可以通过如下命令删除相应的 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: $admin_key" -X PUT -d ' |
| { |
| "methods": ["GET"], |
| "uri": "/hello", |
| "plugins": {}, |
| "upstream": { |
| "type": "roundrobin", |
| "nodes": { |
| "127.0.0.1:1980": 1 |
| } |
| } |
| }' |
| ``` |
