java利用fw.qq获得IP及地址

1、前端JS获取

?

<script type="text/javascript" src="http://fw.qq.com/ipaddress"></script><script type="text/javascript">document.write(IPData.join(' '));</script>

?或者

<script type="text/javascript" src="http://fw.qq.com/ipaddress"></script><script type="text/javascript">document.write(IPData[0]+','+IPData[1]+','+IPData[2] + ',' + IPData[3]);</script>

?

但是这里要注意的是编码集不能是UTF-8的，也就是说不能加

?

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

?

可以是

<meta http-equiv="Content-Type" content="text/html"; charset="gb2312" />

?页面保存的时候字符集应该与其对应.

2、java后台

?

public class IP {/** * @return String[] 0:ip,1:**,2:省份,3:城市 */public static String[] getIP() {String[] retStrArr = { "IP", "中国", "省份", "城市" };try {URL url = new URL("http://fw.qq.com/ipaddress");InputStream conn = (InputStream) url.openStream();ByteArrayOutputStream out = new ByteArrayOutputStream();byte[] buff = new byte[4096];int len = 0;while ((len = conn.read(buff)) > 0) {out.write(buff, 0, len);}// 返回的字符串String result = new String(out.toByteArray());int beginIndex = result.indexOf("(");if (beginIndex >= 0) {int endIndex = result.indexOf(")", beginIndex + 1);if (endIndex > beginIndex) {String[] strArray = result.substring(beginIndex + 1,endIndex).split(",");for (int i = 0; i < strArray.length; i++) {retStrArr[i] = (strArray[i].substring(1, strArray[i].length() - 1));}}}} catch (Exception e) {e.printStackTrace();}return retStrArr;}}

?

也是,文件的的字符集也应该是"gb2312"
