Question

我在Heroku上部署了具有Spark框架的应用程序。它是在Heroku上成功构建的，并且服务器已启动，但是当我尝试从服务器获取响应时，收到HTTP 503，并且在日志中出现以下H14错误：

private void loginUser(String email, String password) {

    if (TextUtils.isEmpty(email)) {
        Toast.makeText(this, "Email cannot be null or empty", Toast.LENGTH_SHORT).show();
        return;
    }

    if (TextUtils.isEmpty(password)) {
        Toast.makeText(this, "Password cannot be null or empty", Toast.LENGTH_SHORT).show();
        return;
    }

    compositeDisposable.add(iMyService.loginUser(email, password)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Consumer<String>() {
                @Override
                public void accept(String response) throws Exception {
                    Intent i = new Intent(LoginActivity.this, MainActivity.class);
                    Toast.makeText(LoginActivity.this, "" + response, Toast.LENGTH_SHORT).show();

                    if (response.equals("Login success")) {
                        // Log.d("myTag", "Login Success");
                        startActivity(i);
                    }
                }
            })
    );


}

Procfile

Spark示例中的代码：

servergossip: java $JAVA_OPTS -cp target/classes:target/dependency/* Main --port $PORT

我使用了public class Main { private static final Logger LOG = LoggerFactory.getLogger(Main.class); public static void main(String[] args) { port(getHerokuAssignedPort()); get("/bot", (req, res) -> { return "hi"; }); } static int getHerokuAssignedPort() { ProcessBuilder processBuilder = new ProcessBuilder(); if (processBuilder.environment().get("PORT") != null) { return Integer.parseInt(processBuilder.environment().get("PORT")); } return 4567; } }之类的命令，但没有任何反应。那怎么了？

您的Procfile当前定义了一个名为servergossip的进程类型。那没有多大意义。将其更改为web进程：

web: java $JAVA_OPTS -cp target/classes:target/dependency/* Main --port $PORT

Heroku上的Java Web应用程序运行但无法回答
