apisix中lua resty etcd出现的问题

[yuqiquan]

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:2.15.0

I know the problem, let's fix it in the original issue.
