将流转换为字符串块，反之亦然
我开发了一个 java/scala XMPP 客户端应用程序，它使用（例如）写入方法异步发送数据，并使用侦听器方法接收数据。 listener 方法接收作为离散 XMPP 消息包的数据，并使用 processPacket 方法处理它们（我可以根据我想要对接收到的数据执行的操作进行修改）
我想要连接从输入流读取数据并将数据写入输出流的第 3 方库。具体来说，我希望使用通过我的 listener 方法接收到的数据来模拟第 3 方库的 inputstream ，并通过以下方式模拟 outputstream我的 write 方法。
做到这一点最简单的方法是什么？我知道这需要从流转换为字符串块，反之亦然。一些提示将不胜感激。
XMPP消息包结构如下（尽管可以根据需要更改）：
<message to = ... from = ...><body>data</body></message>
I have developed a java/scala XMPP client app that sends data asynchronously using (say) a write method and receives data using a listener method. The listener method receives data as discrete XMPP message packets and processes them using a processPacket method (which I can modify based on what I want to do with the received data)
I want to hook up a 3rd party library that reads data from an inputstream and writes to an outputstream. Specifically, I want the inputstream of the 3rd party library to be emulated using the data received via my listener method and the outputstream to be emulated by my write method.
What would be the easiest way to do this? I know that this requires conversion from a stream to chunks of strings and vice-versa. Some hints would be appreciated.
The XMPP message packet structure is as follows (though this can be changed if needed):
<message to = ... from = ...><body>data</body></message>

使用 ByteArrayInputStream 为给定的字符串创建输入流。您必须考虑编码，因为您发送的是字节而不是字符。
相反，您可以写入 ByteArrayOutputStream 并从其字节创建一个新字符串：
同样，不要忘记考虑字符编码。
Use a
ByteArrayInputStreamto create an input stream for a given String. You have to think about encoding, because your sending bytes instead of characters.For the other way round, you write to an
ByteArrayOutputStreamand create a new String from it's bytes:Again - don't forget to think about character encoding.
