nacos config_center has problem

[XiaoWeiKIN]

version : v1.5.7

1. 元数据中心比配置中心先启动，导致元数据中心的配置放在配置中心中，元数据中心无法启动。
2. nacos 配置中心账号密码问题

   ConfigCenterConfig
   func (c *ConfigCenterConfig) GetURLMap() url.Values {
    urlMap := url.Values{}
    urlMap.Set(constant.CONFIG_NAMESPACE_KEY, c.Namespace)
    urlMap.Set(constant.CONFIG_GROUP_KEY, c.Group)
    urlMap.Set(constant.CONFIG_CLUSTER_KEY, c.Cluster)
    urlMap.Set(constant.CONFIG_APP_ID_KEY, c.AppId)
    urlMap.Set(constant.CONFIG_LOG_DIR_KEY, c.LogDir)
    return urlMap
   

}

没有添加账号密码到url中

return clients.CreateConfigClient(map[string]interface{}{
	"serverConfigs": svrConfList,
	"clientConfig": nacosconst.ClientConfig{
		TimeoutMs:           uint64(int32(timeout / time.Millisecond)),
		ListenInterval:      uint64(int32(timeout / time.Millisecond)),
		NotLoadCacheAtStart: true,
		LogDir:              url.GetParam(constant.NACOS_LOG_DIR_KEY, ""),
		CacheDir:            url.GetParam(constant.NACOS_CACHE_DIR_KEY, ""),
		Endpoint:            url.GetParam(constant.NACOS_ENDPOINT, ""),
		Username:            url.GetParam(constant.NACOS_USERNAME, ""),
		Password:            url.GetParam(constant.NACOS_PASSWORD, ""),
		NamespaceId:         url.GetParam(constant.NACOS_NAMESPACE_ID, ""),
	},
})

使用的常量不一致 一个是confg.xx 一个是nacos常量。

追加：consumer 和 provider 启动了两个配置中心

有没有Nacos的启动示例

var (
	appName         = "greeterImpl"
	referenceConfig = config.ReferenceConfig{
		InterfaceName: "org.apache.dubbo.UserProvider",
		Cluster:       "failover",
		Registry:      "nacos",
		Protocol:      "tri",
		Generic:       true,
	}
)

跑不起来
