keycloak~11.3.0之后微信认证问题解决

之前写过基于keycloak11.0.3版的微信认证的实现，而在升级到keycloak14.0.0之后，这个认证出现了问题，原因是因为人家keycloak内部源码又变了。

• 影响类文件 server-spi-private/src/main/java/org/keycloak/broker/provider/BrokeredIdentityContext.java
• github地址：https://github.com/keycloak/keycloak/commit/41dc94fead4c20560e0dd96c3efbd7bd10a484b6
• 修改的地方：去掉了code字段，相应的setCode,getCode也去了，在认证后回调的地方也进行了调整

  AuthenticationSessionModel authSession = this.callback.getAndVerifyAuthenticationSession(state);
  session.getContext().setAuthenticationSession(authSession);
  federatedIdentity.setIdpConfig(getConfig());
  federatedIdentity.setIdp(AbstractOAuth2IdentityProvider.this);
  federatedIdentity.setAuthenticationSession(authSession);

上面源代码的调整直接影响了我们的微信认证的集成，我们也需要进行调整Endpoint类中的authResponse方法，也相应的修改即可

 BrokeredIdentityContext federatedIdentity = null;
 if (authorizationCode != null) {
    String response = generateTokenRequest(authorizationCode, wechatFlag).asString();
    logger.info("authResponse.response=" + response);
    federatedIdentity = getFederatedIdentity(response, wechatFlag);

    if (getConfig().isStoreToken()) {
      if (federatedIdentity.getToken() == null)
        federatedIdentity.setToken(response);
    }
    federatedIdentity.setIdpConfig(getConfig());
    federatedIdentity.setIdp(WeiXinIdentityProvider.this);
    //11.3.0之后改成这样了，去掉了code字段
    AuthenticationSessionModel authSession = this.callback.getAndVerifyAuthenticationSession(state);
    session.getContext().setAuthenticationSession(authSession);
    federatedIdentity.setAuthenticationSession(authSession);
    logger.info("authResponse success" + federatedIdentity);
    return callback.authenticated(federatedIdentity);
 }
