Types

type ErrInvalidFile

type ErrInvalidFile struct {
	Format string
	Reason string
}

func (ErrInvalidFile) Error

func (e ErrInvalidFile) Error() string

type LocationInfo

type LocationInfo struct {
	Country      string
	Region       string
	City         string
	Isp          string
	CountryCode  string
	Latitude     string
	Longitude    string
	DistrictCode string
}

LocationInfo stores IP location information.

type Locator

type Locator interface {
	Find(string) (*LocationInfo, error)
	Close() error
}

Locator represents an IP information loc.

func NewLocator

func NewLocator(dataFile, language string) (Locator, error)

NewLocator returns a new IP locator based on extension of given data file.

type LocatorStore

type LocatorStore struct {
	// contains filtered or unexported fields
}

LocatorStore 按照文件路径保存了对应的 Locator，避免重复实例化浪费内存

func (*LocatorStore) Get

func (s *LocatorStore) Get(fpath string) Locator

Get 返回对应路径的 Locator 并将其引用计数加 1，如果 Locator 不存在则返回 nil

func (*LocatorStore) Remove

func (s *LocatorStore) Remove(fpath string)

Remove 将指定路径的 Locator 引用计数减 1 并在为零时从 Store 中移除

func (*LocatorStore) Set

func (s *LocatorStore) Set(fpath string, loc Locator)

Set 将 Locator 按照指定路径保存到 Store 中

type Number2Ip

type Number2Ip struct {
	Key string `json:"key"`
	New string `json:"new"`
	// contains filtered or unexported fields
}
