kong 自定义插件 api.lua写的暴露接口无效

kong版本是2.6.0，简单开发测试了一个插件，代码如下：

api.lua


local kong = kong

return {
    ["/pluginCeck"] = {
        GET = function()
            return kong.response.exit(200, { message = "test" })
        end
    },
}

handler.lua

-- hello-world.handlar.lua
local BasePlugin = require "kong.plugins.base_plugin"

local CustomHandler = BasePlugin:extend()

local resultAns = ">>插件开始运行了\n"

CustomHandler.VERSION = "1.0.0"
CustomHandler.PRIORITY = 10

function CustomHandler:new()
    CustomHandler.super.new(self, "hello-world")
end
function CustomHandler:access(config)
    CustomHandler.super.access(self)

    resultAns = resultAns .. ">>>>>>>执行：access阶段开始\n输出嵌入的内容(请求在还未到达上游服务器)：\n"
    resultAns = resultAns .. "kong.version：\t" .. kong.version .. "\n"
    resultAns = resultAns .. "kong.client.get_ip()：\t" .. kong.client.get_ip() .. "\n"
    resultAns = resultAns .. "kong.request.get_scheme()：\t" .. kong.request.get_scheme() .. "\n"
    resultAns = resultAns .. "kong.request.get_host()：\t" .. kong.request.get_host() .. "\n"
    resultAns = resultAns .. "kong.request.get_port()\t：" .. kong.request.get_port() .. "\n"
    resultAns = resultAns .. "kong.request.get_http_version()：\t" .. kong.request.get_http_version() .. "\n"
    resultAns = resultAns .. "kong.request.get_method()：\t" .. kong.request.get_method() .. "\n"
    resultAns = resultAns .. "kong.request.get_path()：\t" .. kong.request.get_path() .. "\n"
    resultAns = resultAns .. "<<<<<<<执行access阶段结束 \n"

    return kong.response.exit(
            200,
            resultAns,
            {
                ["Content-Type"] = "application/json",
                ["WWW-Authenticate"] = "Basic"
            }
    )
end

return CustomHandler

schema.lua

--  hello-world.schema.lua
local typedefs = require "kong.db.schema.typedefs"
return {
    name = "hello-world",
    fields = {
        {
            consumer = typedefs.no_consumer
        },
        {
            config = {
                type = "record",
                fields = {
                    -- 这里的username, 会显示在插件配置页
                    {
                        username = {
                            type = "array",
                            elements = {type = "string"},
                            default = {}
                        }
                    }
                }
            }
        }
    }
}

并且能在konga配置生效，但是在本地 curl 404
