如何通过java代码登录我的帐户

Question

我试图写一个代码，其中我传递我现有的用户ID和密码，并希望当我执行代码时，它应该询问我的用户ID和密码，然后授权我访问主页。我试图这样做，但到目前为止，它要求用户ID和密码，并在输入凭据后，它向我显示登录（html）页面。

    private static final int MYTHREADS = 50;
    private static Scanner input;

    public static void main(String args[]) throws Exception {

        input = new Scanner (System.in);
        String user, pass;

        System.out.print("Enter your username:");
        user = input.nextLine();

        System.out.print("Enter your Password:");
        pass = input.nextLine();

        if (user.equals("tester") && (pass.equals("12345")))
        {
            System.out.println("welcome");
        }
        else {
            System.out.println("please try again!");
        }


        ExecutorService executor = Executors.newFixedThreadPool(MYTHREADS);
        String[] apiList = {"https://example.com", };

        for (int i = 0; i < apiList.length; i++) {

            String url = apiList[i];
            Runnable worker = new MyRunnable(url);
            executor.execute(worker);
        }
        executor.shutdown();
        // Wait until all threads are finish

        while (!executor.isTerminated()) {

        }
        System.out.println("\nFinished all threads");
    }

    public static class MyRunnable implements Runnable {
        private final String url;

        MyRunnable(String url) {
            this.url = url;
        }

Answer 1

我建议使用javax.ws.rs.client.客户端；

Client client = ClientBuilder.newClient();
HttpAuthenticationFeature feature = HttpAuthenticationFeature.basicBuilder().credentials(login, password).build();
client.register(feature);

关于你的例子，我找不到你在哪里设置你的凭证请求

在您的情况下，也许一些验证器可以帮助：

Authenticator.setDefault (new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
    return new PasswordAuthentication ("username", "password".toCharArray());
}
});
