go.strava

Go.strava provides a complete, including upload, wrapper library for the Strava V3 API. Structs are defined for all the basic types such as athletes, activities and leaderboards. Functions are provided to fetch all these values.

Please note: Every effort is made to keep the API Documentation up to date, however this package may lag behind. If this is impacting your development, please file an issue and it will be addressed as soon as possible.

To install

go get github.com/strava/go.strava

To use, imports as package name strava:

import "github.com/strava/go.strava"

### This document is separated into three parts

• Examples - working code
• Service Documentation - what you can do and how to do it
• Testing

Examples

Make sure to check out the source code as it provides many helpful comments.

• segment_example.go

  This example shows how to pull segment descriptions and leaderboards. To run:

    cd $GOPATH/src/github.com/strava/go.strava/examples
    go run segment_example.go -token=<your-access-token>
  

  A sample access token can be found on the API settings page.

• oauth_example.go

  This example shows how to use OAuthCallbackHandler to simplify the OAuth2 token exchange, as well as how to handle the errors that might occur. To run:

    cd $GOPATH/src/github.com/strava/go.strava/examples
    go run oauth_example.go -id=<your-client-id> -secret=<your-client-secret>
  
    Visit http://localhost:8080/ in your favorite web browser
  

  Your client id and client secret can be found on the API settings page.

• upload.go

  This example shows how to upload data to Strava. It will upload a random GPX file. To run:

    cd $GOPATH/src/github.com/strava/go.strava/examples
    go run upload.go -token=<your-access-token>
  

  The access token must have 'write' permissions which must be created using the OAuth flow, see the above example.

Service Documentation

For full documentation, see the Godoc documentation. Below is a overview of how the library works, followed by examples for all the different calls.

1. All requests should start by creating a client that defines the access token to be used:

    client := strava.NewClient("<an-access-token>", optionalHttpClient)
   

   The library will use the http.DefaultClient by default. If the default client is unavailable, like in the app engine environment for example, you can pass one in as the second parameter.

2. Then a service must be defined that represents a given API request endpoint, for example:

    service := strava.NewClubsService(client)
   

3. Required parameters are passed on call creation, optional parameters are added after, for example:

    call := service.ListMembers(clubId).Page(2).PerPage(50)
   

4. To actually execute the call, run Do() on it:

    members, err := call.Do()
    if e, ok := err.(*strava.Error); ok {
    	// this is a strava provided error
    } else {
    	// regular error, could be internet connectivity problems
    }
   

   This will return members 50-100 of the given clubs. All of these things can be chained together like so:

    members, err := strava.NewClubsService(strava.NewClient(token)).
    	ListMembers(clubId).
    	PerPage(100).
    	Do()
   

Polyline decoding
Activities and segments come with summary polylines encoded using the Google Polyline Format. These can be decoded into a slice of [2]float64 using Decode(), for example: activity.Map.Polyline.Decode(), segment.Map.Polyline.Decode(), or segmentExplorerSegment.Polyline.Decode().

Examples for all the possible calls can be found below:

• Authentication
• Athletes
• Activities
• Comments
• Kudos

Authentication

Related objects: OAuthAuthenticator, AuthorizationResponse.

authenticator := &strava.OAuthAuthenticator{
	CallbackURL: "http://yourdomain/strava/authorize",
}

path, err := authenticator.CallbackPath()
http.HandleFunc(path, authenticator.HandlerFunc(oAuthSuccess, oAuthFailure))

func oAuthSuccess(auth *strava.AuthorizationResponse, w http.ResponseWriter, r *http.Request) {
	// Success
}

func oAuthFailure(err error, w http.ResponseWriter, r *http.Request) {
	// Failure, or access was denied
}

Testing

To test code using this package try the StubResponseClient. This will stub the JSON returned by the Strava API. You'll need to be familiar with raw JSON responses, so see the Documentation

client := strava.NewStubResponseClient(`[{"id": 1,"name": "Team Strava Cycling"}`, http.StatusOK)
clubs, err := strava.NewClubsService(client).Get(1000)

clubs[0].Id == 1

This will return the club provided when creating the client even though you actually wanted club 1000.
