java - 向服务器发送 GPS 数据不起作用？

Question

我正在尝试将 GPS 数据从 Android 手机发送到服务器。但它不起作用。我在这里附上了我的代码 fragment 。请检查并帮助我!

public void onNmeaReceived(long timestamp, String nmea) 
    { 
        String url = "http://www.xyz.com/server.php?DATA=";
        String params = URLEncoder.encode(nmea);
        url = url+params;
        HttpClient client = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(url);
        try {
            HttpResponse httpResponse = client.execute(httppost);
            Log.d("Status", "Request Sent " + httpResponse.getStatusLine().getStatusCode());
            } 
        catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            } 
            Log.d("url", url);          
    }

我的输出是这样的!它被编码并发送。

发送到服务器的数据是，

http://www.xyz.com/server.php?DATA=%24GPGSA%2CA%2C1%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C*1E%0D%0A

数据发送到服务器。 new1.nmea 文件已创建!但是当我输入“cat”查看里面的内容时，文件是空的!

服务器.php

<?php 
//$data = $_POST["DATA"].""; 
$data = file_get_contents('php://input');
$Handle = fopen("/xxx/xxx/new1.nmea", "a");
fwrite($Handle, $data);
fclose($Handle);
?>

我需要在服务器端使用相同格式的数据而不进行任何更改(nmea 0183 格式)。我震惊了!请帮我解决这个问题!

为什么您需要 NMEA 和 LocationUpdates，其中任何一个都可以。当您说您需要 GPS 信息时，您需要 NMEA 字符串还是仅需要精度、时间、速度等位置属性？

当您尝试发送 NMEA 字符串时，您应该在 NMEAListener 中执行 HTTP 请求，而不是在 LocationListener 中执行？我很好奇，这首先的逻辑是什么。
