数据报包转xml

发布于 2024-09-02 00:37:47 字数 811 浏览 3 评论 0原文

我正在尝试使用 XMLPullParser 解析 Soap ProbeMatch 消息。我通过 UDP 多播收到此消息。我使用以下代码来接收它。

byte[] buf = new byte[1900];
DatagramPacket packet = new DatagramPacket(buf, buf.length);

mSocket.receive(packet);

// Damn ugly....
String data = new String(packet.getData())

如果我将 byte[] 转换为 String ，解析器不会吃掉它......有没有更优雅的方法来做到这一点？

当我打印 xml（作为字符串）时，我在字符串末尾得到未使用的字节：

</s12:Envelope>À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?

Im trying to parse a Soap ProbeMatch message with XMLPullParser. I receive this via UDP Multicast. I use the following code to receive it.

byte[] buf = new byte[1900];
DatagramPacket packet = new DatagramPacket(buf, buf.length);

mSocket.receive(packet);

// Damn ugly....
String data = new String(packet.getData())

If i convert the byte[] to String the Parser doesnt eat it... Are there any more elegant ways to do this?

When i print the xml (as String), i get the unused bytes at the end of the String:

</s12:Envelope>À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?À?

首先，我认为您需要按如下方式构造字符串：

String data = new String(packet.getData(), 
                         packet.getOffset(), 
                         packet.getLength());

至于是否有更好的方法。 AIUI 并不是真的，尽管可能有第三方 API 可以使填充/清空数据报变得更容易一些，因为所有字节打包都非常繁琐。

First off, I think you'll want to construct the String as follows:

String data = new String(packet.getData(), 
                         packet.getOffset(), 
                         packet.getLength());

As to there being a better way. AIUI not really, though there might be a third party API out there that makes filling/emptying the datagrams a bit easier, as all the byte packing is very fiddly.
