java - Android应用程序和php之间发送和接收数据的问题

Question

我在将数据从 Android 应用程序发送到 php 页面时遇到问题...我在 android 端有一个按钮，可以将我带到此 Activity :

public class Post extends Activity {

public void postData(View v){
     //Create a new HttpClient and Post Header
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://192.168.1.67/phptester/insertdata.php"); 
        List<BasicNameValuePair> nameValuePairs = new ArrayList<BasicNameValuePair>(4);

        try {
            // Add your data
            nameValuePairs.add(new BasicNameValuePair("id", "1"));
            nameValuePairs.add(new BasicNameValuePair("descr", "Fire"));
            nameValuePairs.add(new BasicNameValuePair("lat", "1.333"));
            nameValuePairs.add(new BasicNameValuePair("lng", "1.333"));

            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            InputStream is = entity.getContent();
            Log.i("postData", response.getStatusLine().toString());



        } catch (IOException e) {
            Log.e("log_tag", "Error in http connection "+e.toString());
        }
}

}

这是我的 php 代码:

  <?php
   $conn = mysql_connect("localhost", "root", "") or die(mysql_error());

   mysql_select_db("locationdb", $conn);

   if (isset($_POST["id"]) && isset($_POST['descr']) && isset($_POST['lat']) && isset($_POST['lng']))
   {
     $id = $_POST["id"];
     $descr = $_POST["descr"]; 
     $lat = $_POST["lat"];
     $lon = $_POST["lon"];

     $query = mysql_query("INSERT INTO location (ID, Description, lat, lng) VALUES('6', '$descr', '1.666', '1.666')");

     echo "data inserted";
     mysql_query($query);

}

else {

    echo "Not data was intered ".mysql_error() ;
}

?>

困扰我的问题是该数据库中没有存储任何数据，我不知道为什么!!!! php 似乎无法从 Android 应用程序获取数据......感谢任何帮助，并提前致谢......

这不是解决方案，但可以帮助您查看服务器将哪些数据发送回您的应用，从而帮助您调试问题。

String response = httpclient.execute(httppost, new BasicResponseHandler());
Log.i("myapp", "Reply from server: " + response);

现在，您从 PHP 脚本中回显返回的任何内容都将打印在 Android 日志中，这可以让您更轻松地了解发生了什么情况。
