httpExchange.getRequestBody()获得的是什么数据,这个函数的作用是什么?可以举个实例吗

//Http请求处理类

InputStream in = new FileInputStream("c:\\jack2.txt");
//InputStream in = httpExchange.getRequestBody(); //获得输入流 the stream from which the request body can be read.

BufferedReader reader = new BufferedReader(new InputStreamReader(in));
String temp = null;
while((temp = reader.readLine()) != null) {
System.out.println("client request:"+temp);
}

httpExchange.sendResponseHeaders(200, responseMsg.length()); //设置响应头属性及响应信息的长度
OutputStream out = httpExchange.getResponseBody(); //获得输出流
out.write(responseMsg.getBytes());
out.flush();
httpExchange.close();

}
}
public static void main(String[] args) throws IOException {

}
}
