yuqiquan opened a new issue, #8138:
URL: https://github.com/apache/apisix/issues/8138

   ### Description
   
   我写了个测试插件 testetcd.lua
   `local ngx = ngx
   local core = require("apisix.core")
   local schema = {
       type = "object",
       properties = {
           key = { type = "string" },
       }
   }
   
   local plugin_name = "testetcd"
   
   local _M = {
       version = 0.1,
       priority = 70,
       name = plugin_name,
       schema = schema,
   }
   
   function _M.check_schema(conf, schema_type)
       return core.schema.check(schema, conf)
   end
   
   function _M.init()
   end
   
   function _M.destroy()
   end
   
   function _M.rewrite(conf, ctx)
   end
   
   
   function _M.access(conf, ctx)
       local key = conf["key"]
       local etcd_cli, prefix, err = core.etcd.new()
       if not etcd_cli then
           core.log.warn("create etcd_cli failed, error --- > " , err)
           return
       end
       -- in etcd v2, get could implicitly turn into readdir
       -- while in v3, we need to do it explicitly
       local res, err = etcd_cli:readdir(key)
       if not res then
           core.log.warn("read etcd value failed, key --- > " , key)
           return
       end
       core.log.warn(core.json.encode(res.body))
   end
   
   function _M.body_filter(conf, ctx)
   
   end
   
   function _M.delayed_body_filter(conf, ctx)
   
   end
   
   return _M
   `
   
   然后在路由中配置该插件 
   
   作用就是访问该路由 ，会在日志中打印etcd中 key为 /testetcd 的value值，
   
   先用命令行 etcdctl put /testetcd hahahah赋值
   
   然后访问 打印出如下信息
   
   
   使用etcdctl get  /testetcd 可以获取到  
   
   
   
   
   
   
   ### Environment
   
   - APISIX version (run `apisix version`):
   - Operating system (run `uname -a`):
   - OpenResty / Nginx version (run `openresty -V` or `nginx -V`):
