package geoip2

import "github.com/oschwald/geoip2-golang"

Package geoip2 provides an easy-to-use API for the MaxMind GeoIP2 and GeoLite2 databases; this package does not support GeoIP Legacy databases.

The structs provided by this package match the internal structure of the data in the MaxMind databases.

See github.com/oschwald/maxminddb-golang for more advanced used cases.

Example

Example provides a basic example of using the API. Use of the Country method is analogous to that of the City method.

Code: 

{
	db, err := Open("test-data/test-data/GeoIP2-City-Test.mmdb")
	if err != nil {
		log.Fatal(err)
	}
	defer db.Close()
	// If you are using strings that may be invalid, check that ip is not nil
	ip := net.ParseIP("81.2.69.142")
	record, err := db.City(ip)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Portuguese (BR) city name: %v\n", record.City.Names["pt-BR"])
	fmt.Printf("English subdivision name: %v\n", record.Subdivisions[0].Names["en"])
	fmt.Printf("Russian country name: %v\n", record.Country.Names["ru"])
	fmt.Printf("ISO country code: %v\n", record.Country.IsoCode)
	fmt.Printf("Time zone: %v\n", record.Location.TimeZone)
	fmt.Printf("Coordinates: %v, %v\n", record.Location.Latitude, record.Location.Longitude)
	// Output:
	// Portuguese (BR) city name: Londres
	// English subdivision name: England
	// Russian country name: Великобритания
	// ISO country code: GB
	// Time zone: Europe/London
	// Coordinates: 51.5142, -0.0931
}

Output:

Portuguese (BR) city name: Londres
English subdivision name: England
Russian country name: Великобритания
ISO country code: GB
Time zone: Europe/London
Coordinates: 51.5142, -0.0931

func (InvalidMethodError) Error 

func (e InvalidMethodError) Error() string

type Reader 

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

Reader holds the maxminddb.Reader struct. It can be created using the Open and FromBytes functions.

func FromBytes 

func FromBytes(bytes []byte) (*Reader, error)

FromBytes takes a byte slice corresponding to a GeoIP2/GeoLite2 database file and returns a Reader struct or an error. Note that the byte slice is use directly; any modification of it after opening the database will result in errors while reading from the database.

func Open 

func Open(file string) (*Reader, error)

Open takes a string path to a file and returns a Reader struct or an error. The database file is opened using a memory map. Use the Close method on the Reader object to return the resources to the system.

func (r *Reader) ASN(ipAddress net.IP) (*ASN, error)

ASN takes an IP address as a net.IP struct and returns a ASN struct and/or an error

func (*Reader) AnonymousIP 

func (r *Reader) AnonymousIP(ipAddress net.IP) (*AnonymousIP, error)

AnonymousIP takes an IP address as a net.IP struct and returns a AnonymousIP struct and/or an error.

func (*Reader) City 

func (r *Reader) City(ipAddress net.IP) (*City, error)

City takes an IP address as a net.IP struct and returns a City struct and/or an error. Although this can be used with other databases, this method generally should be used with the GeoIP2 or GeoLite2 City databases.

func (*Reader) Close 

func (r *Reader) Close() error

Close unmaps the database file from virtual memory and returns the resources to the system.

func (*Reader) ConnectionType 

func (r *Reader) ConnectionType(ipAddress net.IP) (*ConnectionType, error)

ConnectionType takes an IP address as a net.IP struct and returns a ConnectionType struct and/or an error

func (*Reader) Country 

func (r *Reader) Country(ipAddress net.IP) (*Country, error)

func (r *Reader) Domain(ipAddress net.IP) (*Domain, error)

Domain takes an IP address as a net.IP struct and returns a Domain struct and/or an error

func (*Reader) ISP
