I'm trying to login in a php site with an android interface, but I don't know how to send data

我正在尝试登录站点并取回代码，但我得到"密码或登录无效"，但我相信它们都没问题

这是我代码的一部分：

        HttpPost httppost = new HttpPost("http://www3.mackenzie.com.br/tia/index2.php");
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("username", username));
        nameValuePairs.add(new BasicNameValuePair("password", password));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);
        String str = inputStreamToString(response.getEntity().getContent()).toString();

我正在尝试访问此页面：http://www3.mackenzie.com.br/tia/index2.php

不确定我是否应该输入"用户名"和"密码"或其他东西？我该如何识别？伙计们，我的问题可能是什么？

感谢您的帮助=）

对Maxwell Weru的回答稍作修改，我相信他的网址是错误的。并添加一个参数。

HttpPost httppost = new HttpPost("http://www3.mackenzie.com.br/tia/verifica.php");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("alumat", username));
nameValuePairs.add(new BasicNameValuePair("pass", password));
nameValuePairs.add(new BasicNameValuePair("unidade", "001"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

根据您提供的网站，我认为这是您应该编写代码的方式

HttpPost httppost = new HttpPost("http://www3.mackenzie.com.br/tia/index2.php");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("alumat", username));
nameValuePairs.add(new BasicNameValuePair("pass", password));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
