## 定义
|
||
|
||
`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。

|
||
|
||
## 如何开启
|
||
|
||
这是有关如何为特定路由启用 http-logger 插件的示例。
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"plugins": {
|
||
"http-logger": {
|
||
"uri": "http://127.0.0.1:80/postendpoint?param=1"
|
||
}
|
||
},
|
||
"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 | | | 以 Hash 对象方式声明日志格式。对 value 部分，仅支持字符串。如果是以`$`开头，则表明是要获取 [Nginx 内置变量](http://nginx.org/en/docs/varindex.html)。特别的，该设置是全局生效的，意味着指定 log_format 后，将对所有绑定 http-logger 的 Route 或 Service 生效。 |
|
||
|
||
### 设置日志格式示例
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9180/apisix/admin/plugin_metadata/http-logger -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"log_format": {
|
||
"host": "$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://127.0.0.1:2379/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d value='
|
||
{
|
||
"methods": ["GET"],
|
||
"uri": "/hello",
|
||
"plugins": {},
|
||
"upstream": {
|
||
"type": "roundrobin",
|
||
"nodes": {
|
||
"127.0.0.1:1980": 1
|
||
}
|
||
}
|
||
}'
|
||
```
