导入Keycloak中的JSON配置文件

你在学习Golang相关的知识吗？本文《导入Keycloak中的JSON配置文件》，主要介绍的内容就涉及到，如果你想提升自己的开发能力，就不要错过这篇文章，大家要知道编程理论基础和实战操作都是不可或缺的哦！

我已经使用 keycloak 配置了我的 goclient。我正在从我的 go 客户端中存在的 keycloak.json 文件中读取 keycloak 服务器详细信息。

我的整个设置都在 kubernetes 集群中。每次当新的 keycloak 服务器出现时，我应该如何将 keycloak.json 文件传递​​给 go 客户端，以便它可以从 json 文件中读取详细信息？

有没有办法可以获取包含所有客户端配置详细信息的 keycloak.json 文件，而无需登录 keycloak 并下载它？

"realm": "SolutionAdmin",
  "auth-server-url": "localhost:8081/auth",
  "ssl-required": "none",
  "resource": "admin",
  "credentials": {
    "secret": "6ee0f523-c392-4406-bb14-ba315125c6ea"
  },
  "confidential-port": 0
}

解决方案

如果您想要预配置的嵌入式 keycloak 服务器，则需要扩展 keycloakapplication 并将其配置为代替基类触发。在此示例中，keycloakproperties 只是我们在 application.properties 中使用的所有 keycloak 属性的表示。但你可以了解它的要点。公平警告：我没有写这个，但我正在弄清楚同事是如何为另一个项目做的。

public class embeddedkeycloakapplication extends keycloakapplication {

  public final keycloakproperties keycloakproperties;

  public embeddedkeycloakapplication() {

    super();

    keycloakproperties = springcontextadapter.getbean(keycloakproperties.class);
    system.getproperties().putall(keycloakproperties.getrealmproperties());

    createmasterrealmadminuser();

    createrealm();
  }

  private void createmasterrealmadminuser() {

    log.debug("creating administrative user.");

    string username = keycloakproperties.getserver(keycloakproperties.admin_user_username);
    string password = keycloakproperties.getserver(keycloakproperties.admin_user_password);
    string email = keycloakproperties.getserver(keycloakproperties.admin_user_email);

    keycloaksession session = getsessionfactory().create();
    appliancebootstrap appliancebootstrap = new appliancebootstrap(session);

    try {
      session.gettransactionmanager().begin();

      if (!appliancebootstrap.isnomasteruser()) {
        log.debug("administrative user already exists. no work to do.");
        return;
      }

      appliancebootstrap.createmasterrealmuser(username, password);
      realmmodel adminrealm = session.realms().getrealm(config.getadminrealm());
      usermodel adminuser = session.users().getuserbyusername(username, adminrealm);
      adminuser.setemail(email);
      adminuser.setemailverified(true);
      session.gettransactionmanager().commit();
      log.info("created administrative user {}", username);
    } catch (exception ex) {
      log.error("couldn't create keycloak master admin user: {}", ex.getmessage());
      session.gettransactionmanager().rollback();
    }

    session.close();
  }

  private void createrealm() {

    string realmimportfilename = keycloakproperties.getrealmimportfile();
    keycloaksession session = getsessionfactory().create();
    string realmid = keycloakproperties.getrealm(keycloakproperties.realm_id);

    try {
      session.gettransactionmanager().begin();

      realmmanager manager = new realmmanager(session);

      if (manager.getrealm(realmid) != null) {
        log.debug("{} realm already exists. no work to do.", realmid);
        return;
      }

      resource realmimportfile = new classpathresource(realmimportfilename);

      realmrepresentation rep =
          jsonserialization.readvalue(
              realmimportfile.getinputstream(), realmrepresentation.class, true);
      manager.importrealm(rep);
      log.info("imported realm json file {}", realmimportfilename);
      session.gettransactionmanager().commit();
    } catch (exception e) {
      log.error("failed to import realm json file {}: {}", realmimportfilename, e.getmessage(), e);
      session.gettransactionmanager().rollback();
    }

    session.close();
  }

}
