Package github provides a client for using the GitHub API.
|
||
|
|
||
|
Usage:
|
||
|
|
||
|
import "github.com/google/go-github/v24/github" // with go modules enabled (GO111MODULE=on or outside GOPATH)
|
||
|
import "github.com/google/go-github/github" // with go modules disabled
|
||
|
|
||
|
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.
|
||
|
|
||
|

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.
|
||
|
|
||
|

|
||
|
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
|
||
|
}
|
||
|
