Go Client for Google Maps Services

Build Status GoDoc

Description

Use Go? Want to geocode something? Looking for directions? Maybe matrices of directions? This library brings the Google Maps API Web Services to your Go application. Analytics

The Go Client for Google Maps Services is a Go Client library for the following Google Maps APIs:

Keep in mind that the same terms and conditions apply to usage of the APIs when they're accessed through this library.

Support

This library is community supported. We're comfortable enough with the stability and features of the library that we want you to build real production applications on it. We will try to support, through Stack Overflow, the public and protected surface of the library and maintain backwards compatibility in the future; however, while the library is in version 0.x, we reserve the right to make backwards-incompatible changes. If we do remove some functionality (typically because better functionality exists or if the feature proved infeasible), our intention is to deprecate and give developers a year to update their code.

If you find a bug, or have a feature suggestion, please log an issue. If you'd like to contribute, please read How to Contribute.

Requirements

  • Go 1.7 or later.
  • A Google Maps API key.
API keys

Each Google Maps Web Service request requires an API key or client ID. API keys are freely available with a Google Account at Google APIs Console. The type of API key you need is a Server key.

To get an API key:

  1. Visit Google APIs Console and log in with a Google Account.
  2. Select one of your existing projects, or create a new project.
  3. Enable the API(s) you want to use. The Go Client for Google Maps Services accesses the following APIs:
    • Directions API
    • Distance Matrix API
    • Elevation API
    • Geocoding API
    • Places API
    • Roads API
    • Time Zone API
    • Maps Static API
  4. Create a new Server key.
  5. If you'd like to restrict requests to a specific IP address, do so now.

For guided help, follow the instructions for the Directions API. You only need one API key, but remember to enable all the APIs you need. For even more information, see the guide to API keys.

Important: This key should be kept secret on your server.

Installation

To install the Go Client for Google Maps Services, please execute the following go get command.

    go get googlemaps.github.io/maps

Developer Documentation

View the reference documentation

Additional documentation for the included web services is available at developers.google.com/maps and developers.google.com/places.

Usage

Sample usage of the Directions API with an API key:

package main

import (
	"context"
	"log"

	"github.com/kr/pretty"
	"googlemaps.github.io/maps"
)

func main() {
	c, err := maps.NewClient(maps.WithAPIKey("Insert-API-Key-Here"))
	if err != nil {
		log.Fatalf("fatal error: %s", err)
	}
	r := &maps.DirectionsRequest{
		Origin:      "Sydney",
		Destination: "Perth",
	}
	route, _, err := c.Directions(context.Background(), r)
	if err != nil {
		log.Fatalf("fatal error: %s", err)
	}

	pretty.Println(route)
}

Below is the same example, using client ID and client secret (digital signature) for authentication. This code assumes you have previously loaded the clientID and clientSecret variables with appropriate values.

For a guide on how to generate the clientSecret (digital signature), see the documentation for the API you're using. For example, see the guide for the Directions API.

package main

import (
	"context"
	"log"

	"github.com/kr/pretty"
	"googlemaps.github.io/maps"
)

func main() {
	c, err := maps.NewClient(maps.WithClientIDAndSignature("Client ID", "Client Secret"))
	if err != nil {
		log.Fatalf("fatal error: %s", err)
	}
	r := &maps.DirectionsRequest{
		Origin:      "Sydney",
		Destination: "Perth",
	}
	route, _, err := c.Directions(context.Background(), r)
	if err != nil {
		log.Fatalf("fatal error: %s", err)
	}

	pretty.Println(route)
}

Features

Rate limiting

Never sleep between requests again! By default, requests are sent at the expected rate limits for each web service, typically 50 queries per second for free users. If you want to speed up or slow down requests, you can do that too, using maps.NewClient(maps.WithAPIKey(apiKey), maps.WithRateLimit(qps)).

Client IDs

Google Maps APIs Premium Plan customers can use their client ID and secret to authenticate, instead of an API key.

Native types

Native objects for each of the API responses.

Functions

func Encode 

func Encode(path []LatLng) string

Encode returns a new encoded Polyline from the given path.

Types

type AddressComponent 

type AddressComponent struct {
	LongName  string   `json:"long_name"`
	ShortName string   `json:"short_name"`
	Types     []string `json:"types"`
}

AddressComponent is a part of an address

type AddressGeometry 

type AddressGeometry struct {
	Location     LatLng       `json:"location"`
	LocationType string       `json:"location_type"`
	Bounds       LatLngBounds `json:"bounds"`
	Viewport     LatLngBounds `json:"viewport"`
	Types        []string     `json:"types"`
}

AddressGeometry is the location of a an address

type AddressPlusCode 

type AddressPlusCode struct {
	// GlobalCode is a 4 character area code and 6 character or longer local code (849VCWC8+R9).
	GlobalCode string `json:"global_code"`
	// CompoundCode is a 6 character or longer local code with an explicit location (CWC8+R9, Mountain View, CA, USA).
	CompoundCode string `json:"compound_code"`
}

AddressPlusCode (see https://en.wikipedia.org/wiki/Open_Location_Code and https://plus.codes/) is an encoded location reference, derived from latitude and longitude coordinates, that represents an area: 1/8000th of a degree by 1/8000th of a degree (about 14m x 14m at the equator) or smaller.

Plus codes can be used as a replacement for street addresses in places where they do not exist (where buildings are not numbered or streets are not named). The plus code is formatted as a global code and a compound code: Typically, both the global code and compound code are returned. However, if the result is in a remote location (for example, an ocean or desert) only the global code may be returned.

type AltID 

type AltID struct {
	// PlaceID is the APP scoped Place ID that you received when you initially created
	// this Place, before it was given a Google wide Place ID.
	PlaceID string `json:"place_id,omitempty"`
	// Scope is the scope of this alternative place ID. It will always be APP,
	// indicating that the alternative place ID is recognised by your application only.
	Scope string `json:"scope,omitempty"`
}

AltID is the alternative place IDs for a place.

type Anchor 

type Anchor string

Anchor sets how the icon is placed in relation to the specified markers locations

type AutocompleteMatchedSubstring 

type AutocompleteMatchedSubstring struct {
	// Length describes the length of the matched substring.
	Length int `json:"length"`
	// Offset defines the start position of the matched substring.
	Offset int `json:"offset"`
}

AutocompleteMatchedSubstring describes the location of the entered term in the prediction result text, so that the term can be highlighted if desired.

type AutocompletePlaceType 

type AutocompletePlaceType string

AutocompletePlaceType restricts Place Autocomplete API to the results to places matching the specified type.

func ParseAutocompletePlaceType 

func ParseAutocompletePlaceType(placeType string) (AutocompletePlaceType, error)

ParseAutocompletePlaceType will parse a string representation of a AutocompletePlaceTypes.

type AutocompletePrediction 

type AutocompletePrediction struct {
	// Description of the matched prediction.
	Description string `json:"description,omitempty"`
	// PlaceID is the ID of the Place
	PlaceID string `json:"place_id,omitempty"`
	// Types is an array indicating the type of the address component.
	Types []string `json:"types,omitempty"`
	// MatchedSubstring describes the location of the entered term in the prediction
	// result text, so that the term can be highlighted if desired.
	MatchedSubstrings []AutocompleteMatchedSubstring `json:"matched_substrings,omitempty"`
	// Terms contains an array of terms identifying each section of the returned
	// description (a section of the description is generally terminated with a comma).
	Terms []AutocompleteTermOffset `json:"terms,omitempty"`
	// StructuredFormatting contains the main and secondary text of a prediction
	StructuredFormatting AutocompleteStructuredFormatting `json:"structured_formatting,omitempty"`
