## 名称

`request-id` 插件通过 APISIX 为每一个请求代理添加唯一 ID（UUID），以用于追踪 API 请求。该插件在 `header_name` 已经在请求中存在时不会为请求添加新的 ID。

## 属性

| 名称                | 类型    | 必选项   | 默认值         | 有效值 | 描述                           |
| ------------------- | ------- | -------- | -------------- | ------ | ------------------------------ |
| header_name         | string  | 可选 | "X-Request-Id" |        | Request ID header name         |
| include_in_response | boolean | 可选 | false          |        | 是否需要在返回头中包含该唯一ID |

## 如何启用

创建一条路由并在该路由上启用 `request-id` 插件：

```shell
curl http://127.0.0.1:9080/apisix/admin/routes/5 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/hello",
    "plugins": {
        "request-id": {
            "include_in_response": true
        }
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:8080": 1
        }
    }
}'
```

## 测试插件

```shell
$ curl -i http://127.0.0.1:9080/hello
HTTP/1.1 200 OK
X-Request-Id: fe32076a-d0a5-49a6-a361-6c244c1df956
......
```

## 禁用插件

在路由 `plugins` 配置块中删除 `request-id 配置，即可禁用该插件，无需重启 APISIX。

```shell
curl http://127.0.0.1:9080/apisix/admin/routes/5 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/get",
    "plugins": {
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:8080": 1
        }
    }
}'
```
