如何链接 doIfElse Scala Gatling

Question

我们正在尝试将 Gatling 测试从 Scala 迁移到 Java。我们有一个链接一些 exec 的函数，并且在它们之间有一个 doIfElse。尝试在 Java 上添加相同的内容会影响方法的 return 类型并且对 Scala 不是很熟悉，我们不确定如何将整个登录功能迁移到 Java class.

Scala 版本

def loginFlow() = group("Login Flow") {
    {
      login
    }
  }

  def login(): ChainBuilder = exec { session =>
    // Need to construct dynamic urls here and store in session as they won't be evaluated while the scenario is running
    session.set("authorize_url", s"${getBaseUrl()}/authorize")
      .set("redirect_uri", s"${getRedirectURI(Config.TARGET_ENV)}")
      .set("client_id", Config.getProperty("client_id", "152ced50-1369-4b19-8b26-8f3d5d9bfd6a.hmhco.com"))
  }.doIfOrElse(session => session.contains("token")) {
    // If a token is provided for the user, don't login
    exec { session =>
      logger.debug("Using a provided token")
      session
    }
  } {
    exec { session =>
      val username = session("username").as[String]
      val password = session("password").as[String]
      logger.debug(s"Logging In with user: ${username}/${password}")
      session.set("nonce", "99999")
    }
  }

Java

public ChainBuilder loginFlow() {
        return group("Login Flow").on(exec(login()));
    }

    public ChainBuilder login() {
        return exec(session -> {
            Session newSession = session.set("authorize_url", getBaseUrl());
            session.set("redirect_uri", getRedirectURI());
            session.set("client_id", Config.getProperty("client_id", "152ced50-1369-4b19-8b26-8f3d5d9bfd6a.hmhco.com")) // Missing semicolon. When it's added the return type for the method changes.
            return newSession;
        })
                .doIfOrElse(session -> session.contains("token")).then(
                        exec(session -> session)

                );
    }

谢谢。

原来是java代码中缺少else块。由于 Java 不支持 curried 函数，gatling 提供了一些方法以将操作链接在一起。所以基于 Gatling docs，这会成功：

.doIfOrElse(session -> session.contains("token")).then(
                        exec(session -> session)
                ).orElse(session -> {...});
