springboot项目justAuth扩展第二个小程序

1. 首先用的是bootstart

<dependency><groupId>com.youkol.support</groupId><artifactId>justauth-spring-boot-starter</artifactId><version>${justauth-spring-boot.version}</version>
</dependency>

2. 自定义request（枚举类配置方式），继承AuthDefaultRequest 

import com.alibaba.fastjson.JSONObject;
import com.alibaba.fastjson.annotation.JSONField;
import lombok.Data;
import me.zhyd.oauth.cache.AuthStateCache;
import me.zhyd.oauth.config.AuthConfig;
import me.zhyd.oauth.config.AuthSource;
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.request.AuthDefaultRequest;
import me.zhyd.oauth.utils.HttpUtils;
import me.zhyd.oauth.utils.UrlBuilder;public class AuthWechatMiniBrokerRequest extends AuthDefaultRequest {public AuthWechatMiniBrokerRequest(AuthConfig config, AuthSource source) {super(config, ExtendSource.WECHAT_MINI_PROGRAM_BROKER);}public AuthWechatMiniBrokerRequest(AuthConfig config, AuthStateCache authStateCache) {super(config, ExtendSource.WECHAT_MINI_PROGRAM_BROKER, authStateCache);}@Overridepublic AuthToken getAccessToken(AuthCallback authCallback) {// 参见 https://developers.weixin.qq.com/miniprogram/dev/api-backend/open-api/login/auth.code2Session.html 文档// 使用 code 获取对应的 openId、unionId 等字段String response = new HttpUtils(config.getHttpConfig()).get(accessTokenUrl(authCallback.getCode())).getBody();JSCode2SessionResponse accessTokenObject = JSONObject.parseObject(response, JSCode2SessionResponse.class);assert accessTokenObject != null;checkResponse(accessTokenObject);// 拼装结果return AuthToken.builder().openId(accessTokenObject.getOpenid()).unionId(accessTokenObject.getUnionId()).accessToken(accessTokenObject.getSessionKey()).build();}@Overridepublic AuthUser getUserInfo(AuthToken authToken) {// 参见 https://developers.weixin.qq.com/miniprogram/dev/api/open-api/user-info/wx.getUserProfile.html 文档// 如果需要用户信息，需要在小程序调用函数后传给后端return AuthUser.builder().username("").nickname("").avatar("").uuid(authToken.getOpenId()).token(authToken).source(source.toString()).build();}/*** 检查响应内容是否正确** @param response 请求响应内容*/private void checkResponse(JSCode2SessionResponse response) {if (response.getErrorCode() != 0) {throw new AuthException(response.getErrorCode(), response.getErrorMsg());}}@Overrideprotected String accessTokenUrl(String code) {return UrlBuilder.fromBaseUrl(source.accessToken()).queryParam("appid", config.getClientId()).queryParam("secret", config.getClientSecret()).queryParam("js_code", code).queryParam("grant_type", "authorization_code").build();}@Data@SuppressWarnings("SpellCheckingInspection")private static class JSCode2SessionResponse {@JSONField(name = "errcode")private int errorCode;@JSONField(name = "errmsg")private String errorMsg;@JSONField(name = "session_key")private String sessionKey;private String openid;@JSONField(name = "unionid")private String unionId;}
}

3. 自定义AuthSource（枚举类配置方式），继承AuthSource

import me.zhyd.oauth.config.AuthSource;
import me.zhyd.oauth.request.AuthDefaultRequest;public enum ExtendSource implements AuthSource {WECHAT_MINI_PROGRAM_BROKER {@Overridepublic String authorize() {// 参见 https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/login.html 文档throw new UnsupportedOperationException("不支持获取授权 url，请使用小程序内置函数 wx.login() 登录获取 code");}@Overridepublic String accessToken() {// 参见 https://developers.weixin.qq.com/miniprogram/dev/api-backend/open-api/login/auth.code2Session.html 文档// 获取 openid, unionId , session_key 等字段return "https://api.weixin.qq.com/sns/jscode2session";}@Overridepublic String userInfo() {// 参见 https://developers.weixin.qq.com/miniprogram/dev/api/open-api/user-info/wx.getUserProfile.html 文档throw new UnsupportedOperationException("不支持获取用户信息 url，请使用小程序内置函数 wx.getUserProfile() 获取用户信息");}@Overridepublic Class<? extends AuthDefaultRequest> getTargetClass() {return AuthWechatMiniBrokerRequest.class;}}
}

4. yml配置

justauth:enabled: truetype:WECHAT_MINI_PROGRAM: # 微信小程序client-id: ${wx.miniapp.appid}client-secret: ${wx.miniapp.secret}ignore-check-redirect-uri: trueignore-check-state: true # 微信小程序，不会使用到 state，所以不进行校验extend:enum-class: com.demo.module.system.framework.justauth.extend.ExtendSourceconfig:WECHAT_MINI_PROGRAM_BROKER:request-class: com.demo.module.system.framework.justauth.extend.AuthWechatMiniBrokerRequestclient-id: wxea86b728b1e5ca8hclient-secret: c69e4d7b65b48h9150235e8de55b246cignore-check-redirect-uri: trueignore-check-state: true # 微信小程序，不会使用到 state，所以不进行校验cache:type: REDISprefix: 'social_auth_state:' # 缓存前缀，目前只对 Redis 缓存生效，默认 JUSTAUTH::STATE::timeout: 24h # 超时时长，目前只对 Redis 缓存生效，默认 3 分钟

配置就是上面的配置，具体使用参看官网文档：
