Functions ¶
func CancelListenConfig ¶
func CancelListenConfig(client config_client.IConfigClient, dataId, group string) error
CancelListenConfig 取消配置监听
PS: 如果未监听,将返回nil.
func DeleteConfig ¶
func DeleteConfig(client config_client.IConfigClient, dataId, group string) (bool, error)
DeleteConfig 删除配置
@param dataId 不能为"" @param group 不能为""
PS: 如果配置不存在,将返回(true, nil).
func DeregisterInstance ¶
func DeregisterInstance(namingClient naming_client.INamingClient, instance vo.DeregisterInstanceParam) (bool, error)
DeregisterInstance 注销实例 *
- ClusterName 默认:DEFAULT
- GroupName 默认:DEFAULT_GROUP
func GetConfig ¶
func GetConfig(client config_client.IConfigClient, dataId, group string) (string, error)
GetConfig 获取配置
@param dataId 不能为"" @param group 不能为""
PS: (1) 如果不存在对应的配置,将返回("", nil); (2) 发布完立即获取配置,且之前未发布过dataId、group一致的配置,此时将得到"".(需要等一会才会发布生效,但实际场景中不存在此种情况)
func GetCriticalScore ¶
func GetCriticalScore() float64
func ListenConfig ¶
func ListenConfig(client config_client.IConfigClient, dataId, group string, callback func(namespaceId, dataId, group, content string)) error
ListenConfig 监听配置变化
@param dataId 不能为"" @param group 不能为""
PS: (1) 监听时,对应配置可以不存在; (2) 如果发布内容与当前内容一致,不会触发回调; (3) 能监听delete操作,如果原先配置存在,delete将触发回调,但二次delete将不会触发回调.
func NewConfigClient ¶
func NewConfigClient(config *NacosConfig, outputDir string, logLevel NacosLogLevel) (config_client.IConfigClient, error)
NewConfigClient 动态配置客户端
func NewNamingClient ¶
func NewNamingClient(config *NacosConfig, outputDir string, logLevel NacosLogLevel) (naming_client.INamingClient, error)
NewNamingClient 服务发现客户端
@param logDir 日志的目录(会尝试创建目录) @param level 日志级别(可以为nil,默认依据 mainControl.IsDebug())
func PublishConfig ¶
func PublishConfig(client config_client.IConfigClient, dataId, group, content string, configType vo.ConfigType) (bool, error)
PublishConfig 发布配置
@param dataId 不能为"",且中间不能有空格 @param group 不能为"",且中间不能有空格 @param content 不能为blank @param configType 配置的类型
PS: 如果配置已存在,将覆盖.
func RegisterInstance ¶
func RegisterInstance(namingClient naming_client.INamingClient, param vo.RegisterInstanceParam) (bool, error)
RegisterInstance 注册实例 *
- ClusterName 默认:DEFAULT
- GroupName 默认:DEFAULT_GROUP
func SearchConfig ¶
func SearchConfig(client config_client.IConfigClient, search, dataId, group string, pageNo, pageSize int) (*model.ConfigPage, error)
SearchConfig 搜索配置
TODO: 待研究,目前没遇到相关使用场景 Deprecated @param search require search=accurate--精确搜索 search=blur--模糊搜索
func SelectAllInstances ¶
func SelectAllInstances(namingClient naming_client.INamingClient, param vo.SelectAllInstancesParam) ([]model.Instance, error)
SelectAllInstances 获取所有的实例列表
返回全部实例列表,包括:healthy=false、enable=false、weight<=0 TODO: ??? nacos1.4.2,通过此方法无法获取到“下线”的服务,难道"下线"不等于"enable == false"?后续到 nacos2.x 最新版上再试试
func SelectInstances ¶
func SelectInstances(namingClient naming_client.INamingClient, param vo.SelectInstancesParam) ([]model.Instance, error)
SelectInstances 获取实例列表
只返回满足这些条件的实例列表:healthy=${HealthyOnly}、enable=true、weight>0. !!!:返回的错误不为nil的话,需要用进行 "nacosError" 判断.(1种特殊情况)
func SelectOneHealthyInstance ¶
func SelectOneHealthyInstance(namingClient naming_client.INamingClient, param vo.SelectOneHealthInstanceParam) (*model.Instance, error)
SelectOneHealthyInstance 获取一个健康的实例(加权随机轮询)
按加权随机轮询的负载均衡策略返回一个健康的实例 实例必须满足的条件:health=true、enable=true、weight>0 !!!:返回的错误不为nil的话,需要用进行 "nacosError" 判断.(2种特殊情况,通过"nacosError.IsInstanceListEmpty()"和"nacosError.IsHealthyInstanceListEmpty()")
@return 2个返回值,必定有1个不为nil
func SetCriticalScore ¶
func UpdateInstance ¶
func UpdateInstance(namingClient naming_client.INamingClient, param vo.UpdateInstanceParam) (bool, error)
Types ¶
type NacosConfig ¶

type NacosLogLevel *string
type NacosNamingConfig ¶
type NacosNamingConfig struct { // 注册的服务实例是否是临时的? Ephemeral bool }
NacosNamingConfig "服务发现"的配置
