J2ME实现手机图片上传的一些小经验

conn = (HttpConnection) Connector.open(server,Connector.READ_WRITE,true);

conn.setRequestProperty("Content-Type","application/octet-stream");

conn.setRequestProperty("Content-Length", String.valueOf(data.length));

conn.setRequestProperty("Connection","Keep-Alive");

conn.setRequestProperty("Connection","close");
//conn.setRequestProperty("User-Agent", "J2me/Client");

conn.setRequestMethod(HttpConnection.POST);

os = conn.openOutputStream();

os.write(data);

StringBuffer sb=new StringBuffer();

sb.append("POST ");sb.append(URL.query);sb.append(" HTTP/1.1\r\n");

sc = (SocketConnection)Connector.open("socket://"+URL.host+":"+URL.port);

is = sc.openInputStream();

os = sc.openOutputStream();

os.write(sb.toString().getBytes());

os.write(data);
