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

http://127.0.0.1:9090/v1/server_info`):
