Overview

Package github provides a client for using the GitHub API.

Usage:

import "github.com/google/go-github/github"

Construct a new GitHub client, then use the various services on the client to access different parts of the GitHub API. For example:

client := github.NewClient(nil)

// list all organizations for user "willnorris"
orgs, _, err := client.Organizations.List(ctx, "willnorris", nil)

Some API methods have optional parameters that can be passed. For example:

client := github.NewClient(nil)

// list public repositories for org "github"
opt := &github.RepositoryListByOrgOptions{Type: "public"}
repos, _, err := client.Repositories.ListByOrg(ctx, "github", opt)

The services of a client divide the API into logical chunks and correspond to the structure of the GitHub API documentation at https://developer.github.com/v3/.

NOTE: Using the https://godoc.org/context package, one can easily pass cancelation signals and deadlines to various services of the client for handling a request. In case there is no context available, then context.Background() can be used as a starting point.

For more sample code snippets, head over to the https://github.com/google/go-github/tree/master/example directory.

Authentication

The go-github library does not directly handle authentication. Instead, when creating a new client, pass an http.Client that can handle authentication for you. The easiest and recommended way to do this is using the golang.org/x/oauth2 library, but you can always use any other library that provides an http.Client. If you have an OAuth2 access token (for example, a personal API token), you can use it with the oauth2 library using:

import "golang.org/x/oauth2"

func main() {
	ctx := context.Background()
	ts := oauth2.StaticTokenSource(
		&oauth2.Token{AccessToken: "... your access token ..."},
	)
	tc := oauth2.NewClient(ctx, ts)

	client := github.NewClient(tc)

	// list all repositories for the authenticated user
	repos, _, err := client.Repositories.List(ctx, "", nil)
}

Note that when using an authenticated Client, all calls made by the client will include the specified OAuth token. Therefore, authenticated clients should almost never be shared between different users.

See the oauth2 docs for complete instructions on using that library.

For API methods that require HTTP Basic Authentication, use the BasicAuthTransport.

GitHub Apps authentication can be provided by the https://github.com/bradleyfalzon/ghinstallation package.

import "github.com/bradleyfalzon/ghinstallation"

func main() {
	// Wrap the shared transport for use with the integration ID 1 authenticating with installation ID 99.
	itr, err := ghinstallation.NewKeyFromFile(http.DefaultTransport, 1, 99, "2016-10-19.private-key.pem")
	if err != nil {
		// Handle error.
	}

	// Use installation transport with client
	client := github.NewClient(&http.Client{Transport: itr})

	// Use client...
}

Rate Limiting

GitHub imposes a rate limit on all API clients. Unauthenticated clients are limited to 60 requests per hour, while authenticated clients can make up to 5,000 requests per hour. The Search API has a custom rate limit. Unauthenticated clients are limited to 10 requests per minute, while authenticated clients can make up to 30 requests per minute. To receive the higher rate limit when making calls that are not issued on behalf of a user, use UnauthenticatedRateLimitedTransport.

The returned Response.Rate value contains the rate limit information from the most recent API call. If a recent enough response isn't available, you can use RateLimits to fetch the most up-to-date rate limit data for the client.

To detect an API rate limit error, you can check if its type is *github.RateLimitError:

repos, _, err := client.Repositories.List(ctx, "", nil)
if _, ok := err.(*github.RateLimitError); ok {
	log.Println("hit rate limit")
}

Learn more about GitHub rate limiting at https://developer.github.com/v3/#rate-limiting.

Accepted Status

Some endpoints may return a 202 Accepted status code, meaning that the information required is not yet ready and was scheduled to be gathered on the GitHub side. Methods known to behave like this are documented specifying this behavior.

To detect this condition of error, you can check if its type is *github.AcceptedError:

stats, _, err := client.Repositories.ListContributorsStats(ctx, org, repo)
if _, ok := err.(*github.AcceptedError); ok {
	log.Println("scheduled on GitHub side")
}

Conditional Requests

The GitHub API has good support for conditional requests which will help prevent you from burning through your rate limit, as well as help speed up your application. go-github does not handle conditional requests directly, but is instead designed to work with a caching http.Transport. We recommend using https://github.com/gregjones/httpcache for that.

Learn more about GitHub conditional requests at https://developer.github.com/v3/#conditional-requests.

Creating and Updating Resources

All structs for GitHub resources use pointer values for all non-repeated fields. This allows distinguishing between unset fields and those set to a zero-value. Helper functions have been provided to easily create these pointers for string, bool, and int values. For example:

// create a new private repository named "foo"
repo := &github.Repository{
	Name:    github.String("foo"),
	Private: github.Bool(true),
}
client.Repositories.Create(ctx, "", repo)

Users who have worked with protocol buffers should find this pattern familiar.

Pagination

All requests for resource collections (repos, pull requests, issues, etc.) support pagination. Pagination options are described in the github.ListOptions struct and passed to the list methods directly or as an embedded type of a more specific list options struct (for example github.PullRequestListOptions). Pages information is available via the github.Response struct.

client := github.NewClient(nil)

opt := &github.RepositoryListByOrgOptions{
	ListOptions: github.ListOptions{PerPage: 10},
}
// get all pages of results
var allRepos []*github.Repository
for {
	repos, resp, err := client.Repositories.ListByOrg(ctx, "github", opt)
	if err != nil {
		return err
	}
	allRepos = append(allRepos, repos...)
	if resp.NextPage == 0 {
		break
	}
	opt.Page = resp.NextPage
}

Functions

func Bool

func Bool(v bool) *bool

Bool is a helper routine that allocates a new bool value to store v and returns a pointer to it.

func CheckResponse

func CheckResponse(r *http.Response) error

CheckResponse checks the API response for errors, and returns them if present. A response is considered an error if it has a status code outside the 200 range or equal to 202 Accepted. API error responses are expected to have either no response body, or a JSON response body that maps to ErrorResponse. Any other response body will be silently ignored.

The error type will be *RateLimitError for rate limit exceeded errors, *AcceptedError for 202 Accepted status codes, and *TwoFactorAuthError for two-factor authentication errors.

func DeliveryID

func DeliveryID(r *http.Request) string

DeliveryID returns the unique delivery ID of webhook request r.

GitHub API docs: https://developer.github.com/v3/repos/hooks/#webhook-headers

func Int

func Int(v int) *int

Int is a helper routine that allocates a new int value to store v and returns a pointer to it.

func Int64

func Int64(v int64) *int64

Int64 is a helper routine that allocates a new int64 value to store v and returns a pointer to it.

func ParseWebHook

func ParseWebHook(messageType string, payload []byte) (interface{}, error)

ParseWebHook parses the event payload. For recognized event types, a value of the corresponding struct type will be returned (as returned by Event.ParsePayload()). An error will be returned for unrecognized event types.

Example usage:

func (s *GitHubEventMonitor) ServeHTTP(w http.ResponseWriter, r *http.Request) {
  payload, err := github.ValidatePayload(r, s.webhookSecretKey)
  if err != nil { ... }
  event, err := github.ParseWebHook(github.WebHookType(r), payload)
  if err != nil { ... }
  switch event := event.(type) {
  case *github.CommitCommentEvent:
      processCommitCommentEvent(event)
  case *github.CreateEvent:
      processCreateEvent(event)
  ...
  }
}

func String

func String(v string) *string

String is a helper routine that allocates a new string value to store v and returns a pointer to it.

func Stringify

func Stringify(message interface{}) string

Stringify attempts to create a reasonable string representation of types in the GitHub library. It does things like resolve pointers to their values and omits struct fields with nil values.

func ValidatePayload

func ValidatePayload(r *http.Request, secretKey []byte) (payload []byte, err error)

ValidatePayload validates an incoming GitHub Webhook event request and returns the (JSON) payload. The Content-Type header of the payload can be "application/json" or "application/x-www-form-urlencoded". If the Content-Type is neither then an error is returned. secretKey is the GitHub Webhook secret message.

Example usage:

func (s *GitHubEventMonitor) ServeHTTP(w http.ResponseWriter, r *http.Request) {
  payload, err := github.ValidatePayload(r, s.webhookSecretKey)
  if err != nil { ... }
  // Process payload...
}

func WebHookType

func WebHookType(r *http.Request) string

WebHookType returns the event type of webhook request r.

GitHub API docs: https://developer.github.com/v3/repos/hooks/#webhook-headers

	Response *http.Response // HTTP response that caused this error
	Message  string         `json:"message"` // error message

	// RetryAfter is provided with some abuse rate limit errors. If present,
	// it is the amount of time that the client should wait before retrying.
	// Otherwise, the client should try again later (after an unspecified amount of time).
