从 android 发出 post 请求后 $_POST 为空

Question

我正在尝试使用 android 和 php 登录系统。我可以从 url 读取响应，但 $_POST 数组总是空的。我是新手，所以任何帮助都将不胜感激。这是我的 android 代码。

protected String doInBackground(String... params) {     
        try {
            String link="http://10.0.2.2/monitorhealth";

            HttpClient httpClinet=new DefaultHttpClient();
            HttpPost httppost=new HttpPost(link);

            List<NameValuePair> nameValuePairs=new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("username","X"));
            nameValuePairs.add(new BasicNameValuePair("password","Y"));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            HttpResponse response=httpClinet.execute(httppost);

            InputStream inputStream=response.getEntity().getContent();
            InputStreamReader inputStreamReader=new InputStreamReader(inputStream);
            BufferedReader bufferedReader=new BufferedReader(inputStreamReader);
            StringBuilder sb=new StringBuilder();
            String line;

            while((line=bufferedReader.readLine())!=null){
                sb.append(line);

            }
            Log.e("Response","Received:"+sb.toString());
            return sb.toString();
}

在 index.php 中只有一条语句 $_POST['username] 显示错误。

发现错误。只需要更正网址。替换为

<code>
String link="http://10.0.2.2/monitorhealth/index.php";
</code>
