Quickly get the third-party authorized login component – JustAuth

Quick use (take QQ as an example):

1. If it is the first time to use it, you need to apply for a developer on the “QQ Internet Platform”, create an application and copy three information: App ID, App Key and website callback domain

2. Integrate JustAuth

Add dependencies

<dependency><groupId>me.zhyd.oauth</groupId><artifactId>JustAuth</artifactId><version>${latest.version}</version></dependency>

• Create a request and add the three information from the first step

AuthRequest authRequest = new AuthQqRequest(AuthConfig.builder().clientId("App ID").clientSecret("App Key").redirectUri("网站回调域").build());

• Generate an authorization address
  This link can be redirected directly in the background, or it can be returned to the frontend to jump String authorizeUrl = authRequest.authorize(AuthStateUtils.createState());
  Or generate an authorization page
  authRequest.authorize(“state”); auth_code After version 1.8.0, you can use the AuthCallback class as a parameter of the callback interface// Note: By default, JustAuth saves the state for 3 minutes, and if it is not used within 3 minutes, the expired stateauthRequest.login(callback) will be automatically cleared;
