使用套接字从服务器获取请求

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: www.ibm/developerworks/java/library/wi-jio/ [ ^ ] developers.sun/mobility/midp/articles/midp2network/ [ ^ ] 还是您可能是说用J2SE而不是J2ME: java.sun/developer/technicalArticles/releases/nio/ [ ^ ] www.tutorialspoint/java/java_networking.htm [ ^ ] 祝你好运！ 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: www.ibm/developerworks/java/library/wi-jio/[^] developers.sun/mobility/midp/articles/midp2network/[^] or did you maybe mean J2SE instead of J2ME: java.sun/developer/technicalArticles/releases/nio/[^] www.tutorialspoint/java/java_networking.htm[^] 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: www.sendspace/file/972g2a 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: www.sendspace/file/972g2a I very hope that problem will be solved. Additional information - in archive. Please, help.
