vts动态配置

1.依赖模块

njet_ctrl.conf:

load_module modules/njt_http_vtsc_module.so;

njet.conf:

load_module modules/njt_http_vtsd_module.so;

2.指令说明

动态配置无特殊的指令。

3.配置说明

主要配置示例

4.API

4.1 API 列表

查询接口

curl -X GET http://IP+port/api/v1/config/http_vts

修改接口

curl PUT http://IP+port/api/v1/config/http_vts

4.2 调用样例

4.2.1 GET 查询vts 当前配置

使用GET方法获取当前VTS模块的设置，使用PUT 方法更新VTS模块的设置。 PUT时使用的报文格式与GET获取到的报文格式一致。

查询当前VTS模块的配置：

curl -X GET http://127.0.0.1:8443/api/v1/config/http_vts

返回：
{
  "vhost_traffic_status_filter_by_set_key": "\"$request_uri\" \"$server_name\"",
  "servers": [
    {
      "listens": [
        "0.0.0.0:8081"
      ],
      "serverNames": [
        "server1",
        "server11"
      ],
      "locations": [
        {
          "location": "/",
          "vhost_traffic_status": true
        },
        {
          "location": "/a",
          "vhost_traffic_status": true
        }
      ]
    },
    {
      "listens": [
        "0.0.0.0:8082"
      ],
      "serverNames": [
        "server2"
      ],
      "locations": [
        {
          "location": "/",
          "vhost_traffic_status": true
        },
        {
          "location": "/c",
          "vhost_traffic_status": true
        },
        {
          "location": "/d",
          "vhost_traffic_status": true
        }
      ]
    },
    {
      "listens": [
        "0.0.0.0:8083"
      ],
      "serverNames": [
        "server3"
      ],
      "locations": [
        {
          "location": "/",
          "vhost_traffic_status": true
        },
        {
          "location": "/a",
          "vhost_traffic_status": true
        },
        {
          "location": "/b",
          "vhost_traffic_status": true
        }
      ]
    }
  ]
}

4.2.2 更新当前的配置：

PUT http://127.0.0.1/api/v1/config/http_vts HTTP/1.1
content-type: application/json

{
  "vhost_traffic_status_filter_by_set_key": "\"$status\" \"$server_name::$request_uri\"",

        "server1",
        "server11"
      ],
      "locations": [
        {
          "location": "/",
          "vhost_traffic_status": true
        },
        {
          "location": "/a",
          "vhost_traffic_status": false
        }
      ]
    },
    {
      "listens": [
        "0.0.0.0:8082"
      ],
      "serverNames": [
        "server2"
      ],
      "locations": [
        {
          "location": "/",

        },
        {

        }
      ]
    },
    {
      "listens": [
