使用java作为flex的客户端

最近拿java写了个网页游戏的外挂，模拟flex客户端与服务器通信。
使用的框架：blazeds
核心代码

public static ASObject sendAmfRequest(String method,Object... params){
AMFConnection connection = new AMFConnection();
try {
connection.addHttpRequestHeader("Content-Type", "application/x-amf");
connection.connect(urlstr);
return (ASObject)connection.call(method, params);
} catch (Exception e) {
e.printStackTrace();
} finally {
connection.close();
}
return null;
}
