php - 将数据从 Android 发送到 PHP

Question

起初，我对这些东西很陌生，所以我希望这不是一个非常基本的问题。我正在尝试从 PHP 网络获取我的 Android 应用程序中的数据，PHP 有一些函数可以返回一些数据，但是要调用它们，我需要先从 android 应用程序发送和字符串。我正在尝试搜索如何做到这一点，但我什么也没找到。任何人都可以帮助我吗？谢谢

 public void getServerData() throws JSONException, ClientProtocolException, IOException {               

        HttpParams httpParams = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);
        HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
        HttpClient client = new DefaultHttpClient(httpParams);
        HttpPost request = new HttpPost(url);

        request.setHeader( "Content-Type", "application/json" );        

        JSONObject json = new JSONObject();         
        json.put("type", "register");
        json.put("user_name", "colors");
        json.put("user_password", "colors123");

        Log.i("jason Object", json.toString());        

        StringEntity se = new StringEntity(json.toString());                 
        se.setContentEncoding("UTF-8");
        se.setContentType("application/json");

        String line = null;
        try {
