前言

公共接口，定义了对第三方平台进行授权、登录、撤销授权和刷新 token 的操作

1. 基本知识

先看源码基本API接口：

import me.zhyd.oauth.enums.AuthResponseStatus;
import me.zhyd.oauth.exception.AuthException;
import me.zhyd.oauth.model.AuthCallback;
import me.zhyd.oauth.model.AuthResponse;
import me.zhyd.oauth.model.AuthToken;

/**
 * JustAuth {@code Request}公共接口，所有平台的{@code Request}都需要实现该接口
 * <p>
 * {@link AuthRequest#authorize()}
 * {@link AuthRequest#authorize(String)}
 * {@link AuthRequest#login(AuthCallback)}
 * {@link AuthRequest#revoke(AuthToken)}
 * {@link AuthRequest#refresh(AuthToken)}
 *
 * @author yadong.zhang (yadong.zhang0415(a)gmail.com)
 * @since 1.8
 */
public interface AuthRequest {

    /**
     * 返回授权url，可自行跳转页面
     * <p>
     * 不建议使用该方式获取授权地址，不带{@code state}的授权地址，容易受到csrf攻击。
     * 建议使用{@link AuthDefaultRequest#authorize(String)}方法生成授权地址，在回调方法中对{@code state}进行校验
     *
     * @return 返回授权地址
     */
    @Deprecated
    default String authorize() {
        throw new AuthException(AuthResponseStatus.NOT_IMPLEMENTED);
    }

    /**
     * 返回带{@code state}参数的授权url，授权回调时会带上这个{@code state}
     *
     * @param state state 验证授权流程的参数，可以防止csrf
     * @return 返回授权地址
     */
    default String authorize(String state) {
        throw new AuthException(AuthResponseStatus.NOT_IMPLEMENTED);
    }

    /**
     * 第三方登录
     *
     * @param authCallback 用于接收回调参数的实体
     * @return 返回登录成功后的用户信息
     */
    default AuthResponse login(AuthCallback authCallback) {
        throw new AuthException(AuthResponseStatus.NOT_IMPLEMENTED);
    }

    /**
     * 撤销授权
     *
     * @param authToken 登录成功后返回的Token信息
     * @return AuthResponse
     */
    default AuthResponse revoke(AuthToken authToken) {
        throw new AuthException(AuthResponseStatus.NOT_IMPLEMENTED);
    }

    /**
     * 刷新access token （续期）
     *
     * @param authToken 登录成功后返回的Token信息
     * @return AuthResponse
     */
    default AuthResponse refresh(AuthToken authToken) {
        throw new AuthException(AuthResponseStatus.NOT_IMPLEMENTED);
    }
}

大致方法如下：

2. Demo

根据上述接口，简单测试下接口功能：

制造一个第三方的类：

package com.example.test;

import me.zhyd.oauth.model.AuthCallback;
import me.zhyd.oauth.model.AuthResponse;
import me.zhyd.oauth.model.AuthToken;
import me.zhyd.oauth.request.AuthRequest;

public class GitHubAuthProvider implements AuthRequest {

    @Override
    public String authorize(String state) {
        // 返回 GitHub 授权 URL，并将 state 参数添加到 URL 中
        return "https://github.com/login/oauth/authorize?client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_REDIRECT_URI&state=" + state;
    }

    @Override
    public AuthResponse login(AuthCallback authCallback) {
        // 模拟 GitHub 登录成功后返回的用户信息
        return new AuthResponse(200, "Success", "GitHubUser,github@example.com");
    }

    @Override
    public AuthResponse revoke(AuthToken authToken) {
        // 撤销授权的具体实现
        return new AuthResponse(200, "Success", "Authorization revoked successfully");
    }

    @Override
    public AuthResponse refresh(AuthToken authToken) {
        // 刷新 Access Token 的具体实现
        return new AuthResponse(200, "Success", "Access Token refreshed successfully");
    }
}

对应的接口测试类如下：

import me.zhyd.oauth.model.AuthCallback;
import me.zhyd.oauth.model.AuthResponse;
import me.zhyd.oauth.model.AuthToken;
import me.zhyd.oauth.request.AuthRequest;

public class test {

    public static void main(String[] args) {
        // 创建一个第三方平台的具体实现对象
        AuthRequest authRequest = new GitHubAuthProvider();

        // 获取授权 URL，传入 state 参数
        String authorizeUrl = authRequest.authorize("random_state_parameter");
        System.out.println("Authorize URL: " + authorizeUrl);

        // 模拟第三方登录操作，传入 AuthCallback 实体
        AuthResponse authResponse = authRequest.login(new AuthCallback());
        System.out.println("Login response: " + authResponse);

        // 模拟撤销授权操作，传入登录成功后返回的 Token 信息
        AuthToken authToken = new AuthToken();
        AuthResponse revokeResponse = authRequest.revoke(authToken);
        System.out.println("Revoke response: " + revokeResponse);

        // 模拟刷新 Access Token 操作，传入登录成功后返回的 Token 信息
        AuthResponse refreshResponse = authRequest.refresh(authToken);
        System.out.println("Refresh response: " + refreshResponse);
    }
}

截图如下：（默认的 toString() 方法返回的对象字符串表示形式）

3. 实战

上述Demo只是一个简易版

在实战中应对各个不同的应用，可以写个模板类

                return (AuthRequest)authRequest;
            }
        }
    }
}

类似的Github第三方平台如下：（以下类为API自带的）

import com.alibaba.fastjson.JSONObject;
import me.zhyd.oauth.cache.AuthStateCache;
import me.zhyd.oauth.config.AuthConfig;
import me.zhyd.oauth.config.AuthDefaultSource;
import me.zhyd.oauth.enums.AuthUserGender;
import me.zhyd.oauth.exception.AuthException;
import me.zhyd.oauth.model.AuthCallback;
import me.zhyd.oauth.model.AuthToken;
import me.zhyd.oauth.model.AuthUser;
import me.zhyd.oauth.utils.GlobalAuthUtils;

import java.util.Map;

/**
 * Github登录
 *
 * @author yadong.zhang (yadong.zhang0415(a)gmail.com)
 * @since 1.0.0
 */
public class AuthGithubRequest extends AuthDefaultRequest {

    public AuthGithubRequest(AuthConfig config) {
        super(config, AuthDefaultSource.GITHUB);
    }

    public AuthGithubRequest(AuthConfig config, AuthStateCache authStateCache) {
        super(config, AuthDefaultSource.GITHUB, authStateCache);
    }

    @Override
    protected AuthToken getAccessToken(AuthCallback authCallback) {
        String response = doPostAuthorizationCode(authCallback.getCode());
        Map<String, String> res = GlobalAuthUtils.parseStringToMap(response);

        this.checkResponse(res.containsKey("error"), res.get("error_description"));

        return AuthToken.builder()
            .accessToken(res.get("access_token"))
            .scope(res.get("scope"))
            .tokenType(res.get("token_type"))
            .build();
    }

    @Override
    protected AuthUser getUserInfo(AuthToken authToken) {
        String response = doGetUserInfo(authToken);
        JSONObject object = JSONObject.parseObject(response);

        this.checkResponse(object.containsKey("error"), object.getString("error_description"));

        return AuthUser.builder()
            .rawUserInfo(object)
            .uuid(object.getString("id"))
            .username(object.getString("login"))
            .avatar(object.getString("avatar_url"))
            .blog(object.getString("blog"))
            .nickname(object.getString("name"))
            .company(object.getString("company"))
            .location(object.getString("location"))
            .email(object.getString("email"))
            .remark(object.getString("bio"))
            .gender(AuthUserGender.UNKNOWN)
            .token(authToken)
            .source(source.toString())
            .build();
    }

    private void checkResponse(boolean error, String error_description) {
        if (error) {
            throw new AuthException(error_description);
        }
    }

}

后续在使用过程的代码如下：

@NonDS
@Slf4j
@RestController
@AllArgsConstructor
@ConditionalOnProperty(value = "social.enabled", havingValue = "true")
public class BladeSocialEndpoint {

	private final SocialProperties socialProperties;

	/**
	 * 授权完毕跳转
	 */
	@RequestMapping("/oauth/render/{source}")
	public void renderAuth(@PathVariable("source") String source, HttpServletResponse response) throws IOException {
		AuthRequest authRequest = SocialUtil.getAuthRequest(source, socialProperties);
		String authorizeUrl = authRequest.authorize(AuthStateUtils.createState());
		response.sendRedirect(authorizeUrl);
	}

	/**
	 * 获取认证信息
	 */
	@RequestMapping("/oauth/callback/{source}")
	public Object login(@PathVariable("source") String source, AuthCallback callback) {
		AuthRequest authRequest = SocialUtil.getAuthRequest(source, socialProperties);
		return authRequest.login(callback);
	}

	/**
	 * 撤销授权
	 */
	@RequestMapping("/oauth/revoke/{source}/{token}")
	public Object revokeAuth(@PathVariable("source") String source, @PathVariable("token") String token) {
		AuthRequest authRequest = SocialUtil.getAuthRequest(source, socialProperties);
		return authRequest.revoke(AuthToken.builder().accessToken(token).build());
	}

	/**
	 * 续期令牌
	 */
	@RequestMapping("/oauth/refresh/{source}")
	public Object refreshAuth(@PathVariable("source") String source, String token) {
		AuthRequest authRequest = SocialUtil.getAuthRequest(source, socialProperties);
		return authRequest.refresh(AuthToken.builder().refreshToken(token).build());
	}


}
