midlet中session处理

参考了sun的一篇文章
http://developers.sun.com/mobility/midp/articles/sessions/

1、在http response的时候获取cookie

java 代码

// Query the server and retrieve the response.
HttpConnection hc= (HttpConnection)Connector.open(url);
InputStream in = hc.openInputStream();

// Read the session ID from a cookie in the response headers.
String cookie = hc.getHeaderField("Set-cookie");
if (cookie != null) {
  int semicolon = cookie.indexOf(';');
  mSession = cookie.substring(0, semicolon);
}

// Read the response from the server.

// Clean up.
in.close();
hc.close();

2、在发送http请求的时候设置cookie

java 代码

// Query the server and retrieve the response.
HttpConnection hc = (HttpConnection)Connector.open(url);
if (mSession != null)
  hc.setRequestProperty("Cookie", mSession);
InputStream in = hc.openInputStream();

// Read the session ID from a cookie in the response headers.
String cookie = hc.getHeaderField("Set-cookie");
if (cookie != null) {
  int semicolon = cookie.indexOf(';');
  mSession = cookie.substring(0, semicolon);
}
// Read the response from the server.
// Clean up.
in.close();
hc.close();
