j2me代理连接返回码总是400的有关问题

j2me代理连接返回码总是400的问题
400是因为错误的语法导致服务器无法理解请求信息。

Consts.debug="启用http代理连接";httpConn = (HttpConnection) Connector.open("http://10.0.0.172:80/kjava.portal?action=xxx");httpConn.setRequestMethod(HttpConnection.GET);//需要改成GET请求httpConn.setRequestProperty("X-Online-Host", "wap.5bingo.cn");httpConn.setRequestProperty("Connection", "Keep-Alive");httpConn.setRequestProperty("Accept","*/*");Consts.debug="连接状态："+httpConn.getResponseCode();//打印出400if (HttpConnection.HTTP_OK == httpConn.getResponseCode()) {}else{}

如果不改成GET请求，需要把地址后面的参数转成hex

public static String bin2hex(String bin) throws UnsupportedEncodingException {	char[] digital = "0A1B2C3D4E5F6789".toCharArray();	StringBuffer sb = new StringBuffer("");	byte[] bs = bin.getBytes("utf-8");	int bit;	for (int i = 0; i < bs.length; i++) {		bit = (bs[i] & 0x0f0) >> 4;		sb.append(digital[bit]);		bit = bs[i] & 0x0f;		sb.append(digital[bit]);	}	return sb.toString();}

String hex=bin2hex("action=xxx");httpConn = (HttpConnection) Connector.open("http://10.0.0.172:80/kjava.portal?"+hex);httpConn.setRequestMethod(HttpConnection.POST);//需要改成POST请求httpConn.setRequestProperty("X-Online-Host", "wap.5bingo.cn");httpConn.setRequestProperty("Connection", "Keep-Alive");httpConn.setRequestProperty("Accept","*/*");

我怎么就没看见POST在作怪呢？呵呵
有些手机不管是post还是get都不会有问题，如N82，但是有些手机需要hex一下，如E73
如果还有问题，全部改成get请求！
