使用套接字从服务器获取请求 [英] Getting request from the server using sockets

问题描述

嗨.我需要从服务器接收响应，该服务器在request(os.write(data))之后发送响应.

Hi. I need to receive a response from server, which sends response after request(os.write(data)).

            try{
                 byte[] data = __selectedString.getBytes();
    os.write(data);
        }
    catch(IOException x)
    {
    }
        try{
        InputStream in = connection.openInputStream();//<== Here I got an exception like "no more input streams available".
       int ch;
       String str = null;
                StringBuffer sb = new StringBuffer();
                while ((ch = in.read()) != -1) {
                    sb.append((char)ch);
                }
                list.append(sb.toString(), null);
                in.close();
list.deleteAll();
       list.append(str, null);
       in.close();
        }
        catch(IOException e)
        {
        }

以这种方式成功执行连接:

Connection successfully performs in this way:

try{
  SocketConnection sc = (SocketConnection)
    Connector.open("socket://" + IP +":13000");
  //OutputStream os = null;
  try{
    os = sc.openOutputStream();
    byte[] data = "Hello from a socket!".getBytes();
    os.write(data);

  }
  finally{
      //sc.close();
      //os.close();
  }
}

我已经用Google搜索过，并且只发现了有关http-Connection的信息，但是我通过套接字直接连接到PC.
请帮忙.

I have Googled and found only about http-Connection, but I connecting directly to my PC via sockets.
Please, help.

推荐答案

您的代码看起来不完整，但我理解(或希望我这样做；)).我想您想要一个简单的tcp/ip客户端/服务器连接.

以下是一些帮助您入门的链接:

http://developers.sun.com/mobility/midp/articles/midp2network/ [ ^ ]

还是您可能是说用J2SE而不是J2ME:

Your code looks incomplete but I understood (or hope I did ;) ) what you want to so. I guess you want a simple tcp/ip client/server connection.

Here are some links to get you started:

http://developers.sun.com/mobility/midp/articles/midp2network/[^]

or did you maybe mean J2SE instead of J2ME:

Good luck!

是的，我用JAVA ME编写，但是我不知道为什么程序无法正常工作.
这是NetBeanse 6.9项目的存档:

我非常希望这个问题能够得到解决.
附加信息-存档中.
请帮助.

Yes I writing in JAVA ME, but i don''t know why program doesn''t work correctly.
this is an archive with NetBeanse 6.9 project:

I very hope that problem will be solved.
Additional information - in archive.
Please, help.
