= OAuth 2.0 WebClient (WebFlux) Sample
|
|
|
|
== GitHub Repositories
|
|
|
|
This guide provides instructions on setting up the sample application, which leverages WebClient OAuth2 integration to display a list of public GitHub repositories that are accessible to the authenticated user.
|
|
|
|
This includes repositories owned by the authenticated user, repositories where the authenticated user is a collaborator, and repositories that the authenticated user has access to through an organization membership.
|
|
|
|
The following sections provide detailed steps for setting up the sample and covers the following topics:

* <<github-register-application,Register OAuth application>>
|
|
* <<github-application-config,Configure application.yml>>

|
=== Register OAuth application
|
|
|
|
To use GitHub's OAuth 2.0 authorization system, you must https://github.com/settings/applications/new[Register a new OAuth application].
|
|
|
|
When registering the OAuth application, ensure the *Authorization callback URL* is set to `http://localhost:8080/login/oauth2/code/client-id`.
|
|
|
|
The Authorization callback URL (redirect URI) is the path in the application that the end-user's user-agent is redirected back to after they have authenticated with GitHub and have granted access to the OAuth application on the _Authorize application_ page.
|
|
|
|
[[github-application-config]]
|
|
=== Configure application.yml
|
|
|
|
Now that you have a new OAuth application with GitHub, you need to configure the sample to use the OAuth application for the _authorization code grant flow_.
|
|
To do so:
|
|
|
|
. Go to `application.yml` and set the following configuration:
|
|
+
|
|
[source,yaml]
|
|
----
|
|
spring:
|
|
security:
|
|
oauth2:
|
|
client:
|
|
registration: <1>
|
|
client-id: <2>
|
|
client-id: replace-with-client-id
|
|
client-secret: replace-with-client-secret
|
|
provider: github
|
|
scope: read:user,public_repo
|
|
----
|
|
+
|
|
.OAuth Client properties
|
|
====
|
|
<1> `spring.security.oauth2.client.registration` is the base property prefix for OAuth Client properties.
|
|
<2> Following the base property prefix is the ID for the `ClientRegistration`, which is github.
|
|
====
|
|
|
|
. Replace the values in the `client-id` and `client-secret` property with the OAuth 2.0 credentials you created earlier.
|
|
|
|
[[github-boot-application]]
|
|
=== Boot up the application
|
|
|
|
Launch the Spring Boot 2.0 sample and go to `http://localhost:8080`.
|
|
You are then redirected to the default _auto-generated_ form login page.
|
|
Log in using *'user'* (username) and *'password'* (password) or click the link to authenticate with GitHub and then you'll be redirected to GitHub for authentication.
|
|
|
|
After authenticating with your GitHub credentials, the next page presented to you is "Authorize application".
|
|
This page will ask you to *Authorize* the application you created in the previous step.
|
|
Click _Authorize application_ to allow the OAuth application to access and display your public repository information.
