事实证实在某些装备上，底层的网络协定栈处置重定向的问题，302响应码告知利用程序内部的处置流程。运用程序应当等候直到响应码即是302。但是有些装备不能准确地从响应中解析出Location字段，这样Location字段的内容是null，响应码存储在了响应的内容之中。因此可采取下面的解决措施.
private void getConnection(String url){
try {
HttpConnection connect = (HttpConnection)Connector.open(url);
int statusCode = connect.getResponseCode();
int port = connect.getPort();
String reConnectUrl = connect.getHeaderField("Location");
System.out.println("服务器响应代码:"+statusCode);
System.out.println("服务器响应端口:"+port);
if((statusCode == HttpConnection.HTTP_TEMP_REDIRECT) || (statusCode == HttpConnection.HTTP_MOVED_TEMP)
|| (statusCode == HttpConnection.HTTP_MOVED_PERM)){
System.out.println("须要连接重定向"),魔兽世界仿盛大私服;
if(reConnectUrl != null){
//重连接
System.out.println("正在重连");
connect.close();
connect = (HttpConnection)Connector.open(reConnectUrl);
System.out.println("重连胜利");

红色部分代码是用来读取信息的,之所以要写得这么麻烦是由于由于手机实现得不同,在一些厂商得手机上并不能获取数据长度,因此用一个字节一个字节得读取比拟稳妥!
