动态配置Map

1.功能描述

该动态模块可以对已经配置的Map映射规则进行更改和动态添加新的http map.

2.依赖模块

njet.conf

load_module /usr/lib/njet/modules/njt_http_dyn_map_module.so;

3.API

3.1 API 列表

查询接口：

GET  http://IP+port/api/v1/config/http_dyn_map

修改接口：

PUT   http://IP+port//api/v1/config/http_dyn_map

动态添加新的http map

  • api 新增type 字段，有效值：

    del： 删除map。同时判断keyFrom,keyTo 是否相同。静态文件配置的不允许删除。

    add：添加新的map。添加时判断是否存在，存在时更新。不存在则添加。存在的判断条件：keyTo是否存在。 其他值：走更新流程。 同时判断keyFrom,keyTo 是否相同。

3.2 调用样例

查询 map

 curl -X 'GET'   'http://192.168.40.158:8088/api/v1/config/http_dyn_map'  |jq
curl -k https://127.0.0.1:18080/?a=aa

curl -k https://127.0.0.1:18080/?a=bb
