环境

1. kong 1.21

2. luarock 3.1.3

3. idea

插件目录

官方网址：https://docs.konghq.com/1.2.x/plugin-development/

kong插件目录规则：

kong.plugins.<plugin_name>.<module_name>(要求对lua模块熟悉)

plugin_name ：这个是插件的名称

module_name ：是插件中模块名称

我们要开发的Hello-World例子目录规则如下：(具体目录规则参考官网https://docs.konghq.com/1.2.x/plugin-development/file-structure/)

假设我们插件存放的位置为：/root/test

创建我们的hello-world

mkdir -p /root/test/kong/plugins/hello-world

创建好文件夹后，下载hello-world例子(https://github.com/brndmg/kong-plugin-hello-world/tree/master/src)

将下载后，src下的所有.lua文件复制到/root/test/kong/plugins/hello-world

到这里就完成了。

插件安装

官方地址：(https://docs.konghq.com/1.2.x/plugin-development/distribution/)

这里不用luarocks安装直接手动安装

1、配置插件所在目录

找到启动kong的配置文件kong.conf

修改lua_package_path，将插件文件添加到这里

将

#lua_package_path = ./?.lua;./?/init.lua;

修改为：

lua_package_path = ./?.lua;./?/init.lua;/root/test?.lua;;

2、告诉kong加载插件

将

#plugins = bundled

修改为：

plugins = bundled,hello-world

配置日志

日志的配置在kong.conf

#admin_error_log = logs/error.log         # Path for Admin API request error
                                          # logs. The granularity of these logs

请对照修改相应部分

验证插件

创建一个service

curl -i -X POST --url http://127.0.0.1:8001/services/ --data 'name=tdt-service' --data 'url=http://www.tianditu.gov.cn/'

为服务指定路由

curl -i -X POST --url http://127.0.0.1:8001/services/tdt-service/routes  --data 'paths[]=/tdt'

添加我们的插件

curl -i -X POST --url http://127.0.0.1:8001/services/tdt-service/plugins/ --data 'name=hello-world'

访问路由

curl -i -X GET  --url http://127.0.0.1:8000/tdt
