Question

我试图通过XAMP将我的Android应用程序与MYSQL连接起来。我一直在寻找其他类似的问题，但任何一个真的帮助了我。我试图在模拟器中运行代码，但它给我带来DB和其他东西的问题。 MYSQL中的表有2个字段，Sensors和Calibrated（两个字符串）。 cm.GetMobileUnits正常工作并返回两个字段的Pair。这是Android代码：

Thread thread = new Thread(new Runnable(){
        @Override
        public void run() {
            try {
                ArrayList<Pair<String, String>> stringList = cm.getMobileUnits("Mobile Device");
                //Log.d("MYSQL", "Tuplas adquiridas");
                String url="http://192.168.1.10/test.php";

                DefaultHttpClient httpClient = new DefaultHttpClient();
                HttpPost httpPost = new HttpPost(url);

                 List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
                 for (int i = 0; i < stringList.size(); i++) {
                     Pair<String, String> pair = stringList.get(i);
                     nameValuePairs.add(new BasicNameValuePair("Sensors", pair.first));
                     nameValuePairs.add(new BasicNameValuePair("Calibrated", pair.second));
                     httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));  
                     HttpResponse httpResponse = httpClient.execute(httpPost);
                     httpResponse.getEntity().consumeContent();

                 }
                     } catch (UnsupportedEncodingException e) 
                     {
                 // TODO Auto-generated catch block
                 e.printStackTrace(); 
                    } catch (ClientProtocolException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IllegalStateException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }     
        }
    });

我的PHP文件：

<?php
$con = mysql_connect("localhost","root","1234");
if (!$con)
 {
  die('Could not connect: ' . mysql_error());
 }

mysql_select_db("eHealthDroid", $con);

$sensors = $_POST['Sensors'];
$calibrated = $_POST['Calibrated'];

$sql = "INSERT INTO mobile_units(sensors,calibrated)values('$sensors', '$calibrated')";
      mysql_query($sql) or die(mysql_error());
mysql_close($con);

?>

现在我有另一个问题......为什么我会在手机上使用WIFI或3G时获得不同的输出？我应该使用哪一个？

使用wifi输出：

08-09 12:53:25.178: I/System.out(6926): [socket][0] connection /192.168.1.10:80;LocalPort=46210(0)

3G输出：

任何帮助都会很棒！感谢

Answer 1

我是否理解您192.168.1.15是您的IDE的PC-Localhost并且您想通过在模拟器中运行的Androidapp连接？如果是，则必须使用“10.0.2.2”作为IP地址。在模拟器中，使用IDE将地址重定向到您的电脑

未连接到IP，您还必须允许您的应用使用互联网连接：

Answer 2

好的，这是令人尴尬的，但至少我找到了解决方案。

我将php文件放在php / www目录中，说实话我不知道为什么我认为这是正确的目录。我检查了默认目录，我发现是httpdocs和...瞧！
