我是Android开发的新手, 我想开发一个Android应用程序,它将数据发送到我的网站,(例如经度和纬度),我的问题是如何从android发送数据以及如何在网站上获取/捕获它。

这可能会有所帮助。我刚才做的一个例子就是将加速数据发送到服务器,这样我就可以将数据存储到mysql数据库中。 要将数据发送到服务器,您可以这样做:
private void sendData(ArrayList<NameValuePair> data)
{
// 1) Connect via HTTP. 2) Encode data. 3) Send data.
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new
HttpPost("http://www.blah.com/AddAccelerationData.php");
httppost.setEntity(new UrlEncodedFormEntity(data));
HttpResponse response = httpclient.execute(httppost);
Log.i("postData", response.getStatusLine().toString());
//Could do something better with response.
}
catch(Exception e)
{
Log.e("log_tag", "Error: "+e.toString());
}
}
然后发送让我们说:
private void sendAccelerationData(String userIDArg, String dateArg, String timeArg,
String timeStamp, String accelX, String accelY, String accelZ)
{
fileName = "AddAccelerationData.php";
//Add data to be send.
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(7);
nameValuePairs.add(new BasicNameValuePair("userID", userIDArg));
nameValuePairs.add(new BasicNameValuePair("date",dateArg));
nameValuePairs.add(new BasicNameValuePair("time",timeArg));
nameValuePairs.add(new BasicNameValuePair("timeStamp",timeStamp));
nameValuePairs.add(new BasicNameValuePair("accelX",accelX));
nameValuePairs.add(new BasicNameValuePair("accelY",accelY));
nameValuePairs.add(new BasicNameValuePair("accelZ",accelZ));
this.sendData(nameValuePairs);
}
然后服务器上的AddAccelerationData.php文件是:
<?php
/*
* What this file does is it:
* 1) Creates connection to database.
* 2) Retrieve the data being send.
* 3) Add the retrieved data to database.
* 4) Close database connection.
*/
require_once '../Connection.php'; //connect to a database/disconnect handler.
require_once '../SendAPI.php'; //deals with sending querys.
$server = new Connection();
$send = new Send();
//Connect to database.
$server->connectDB();
//Retrieve the data.
$userID = $_POST['userID'];
$date = $_POST['date'];
$time = $_POST['time'];
$accelX = $_POST['accelX'];
$accelY = $_POST['accelY'];
$accelZ = $_POST['accelZ'];
//Add data to database. //Personal method to query and add to database.
$send->sendAccelerationData($userID, $date, $time, $timeStamp, $accelX, $accelY, $accelZ);
//Disconnect from database.
$server->disconnectDB();
?>
这是我最近使用的一个例子。只是在php文件中注意。我导入Connection.php 这只是处理与数据库的连接。所以只需用您的代码替换它以连接到MYSQL db。我也导入了SendAPI.php(您可以忽略)这只是我发送数据的类。基本上它包含了我想要使用的一些查询。比如sendAccelerationData()。基本上类与存储过程类似。
