JAVA爬取網站查詢網絡IP所在地
網絡中我們上網都是一個ip地址，在獲取對象網絡ip的時候，如果想查詢他所在網絡的地址怎麼搞呢？上代碼
1.寫一個方法通過站長工具網站查詢到你輸入的ip的地址，需要用URL去爬取網站數據
/**ip就是需要查詢的網絡ip地址，返回的就是一個html*/
public static String getUntil(String ip) {
String str = "";
try {
//創建一個URL實例
URL url = new URL("http://ip.tool.chinaz.com/" + ip);
try {
//通過URL的openStrean方法獲取URL對象所表示的自願字節輸入流
InputStream is = url.openStream();
InputStreamReader isr = new InputStreamReader(is, "utf-8");
//爲字符輸入流添加緩衝
BufferedReader br = new BufferedReader(isr);
String data = br.readLine();//讀取數據
while (data != null) {//循環讀取數據
//System.out.println(data);//輸出數據
data = br.readLine();
str += data;
}
br.close();
isr.close();
is.close();
} catch (IOException e) {
e.printStackTrace();
}
} catch (MalformedURLException e) {
e.printStackTrace();
}
return str;
}
然後把返回的html進行解析，先看一下原型的返回的html
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

我需要把輸出信息的那一塊篩選出來組成有價值的數據
String ipciom = "";
String until = null;
try {
until = getUntil("***.***.***.**");
System.out.printf(until);
int lastHtmlBor = until.lastIndexOf("WhwtdWrap bor-b1s col-gray03");
if (lastHtmlBor > 0) {
int lastHtmlPlr = until.lastIndexOf("clearfix plr10");
String whwtdhalf = until.substring(lastHtmlBor, lastHtmlPlr);
int whwtdhallfSpan = whwtdhalf.indexOf("<span class=\"Whwtdhalf w15-0\">");
int spanLength = whwtdhalf.indexOf("</span>");
String spenLengthStr = whwtdhalf.substring(whwtdhallfSpan, spanLength);
int whtstrLength = spenLengthStr.lastIndexOf(">");
String ip = spenLengthStr.substring(whtstrLength + 1);
int wSpanLastOfIndex = whwtdhalf.lastIndexOf("<span class=\"Whwtdhalf w50-0\">");
int wSpanLastOfs = whwtdhalf.lastIndexOf("</span> ");
String wSpanLastOf = whwtdhalf.substring(wSpanLastOfIndex, wSpanLastOfs);
String addressIp = wSpanLastOf.substring(wSpanLastOf.lastIndexOf(">") + 1);
ipciom += "您的IP是:" + ip + ",IP地址是來自:" + addressIp;
} else {
ipciom += "網站解析錯誤,請檢查IP輸入！";
}
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
System.out.println(ipciom);
OK，這樣獲取到了ip地址信息，（純屬娛樂）！個人使用
