网站域名被做网站的公司擅自更改/常用的关键词挖掘工具有哪些

ip2region

准确率99.9%的ip地址定位库，0.0x毫秒级查询，数据库文件大小只有1.5M，提供了java,php,c,python,nodejs,golang查询绑定和Binary,B树,内存三种查询算法

解压目录如下图：

新建java项目，导入binding/java下的代码，并复制”data/ip2region.db”到“src目录

创建“IPUtil”.java ,内容参考”org.lionsoul.ip2region.test.TestSearcher.java“

package com.xx;

import java.io.File;

import java.lang.reflect.Method;

import org.lionsoul.ip2region.DataBlock;

import org.lionsoul.ip2region.DbConfig;

import org.lionsoul.ip2region.DbSearcher;

import org.lionsoul.ip2region.Util;

public class IPUtil {

public static String getCityInfo(String ip){

//db

String dbPath = IPUtil.class.getResource("/ip2region.db").getPath();

File file = new File(dbPath);

if ( file.exists() == false ) {

System.out.println("Error: Invalid ip2region.db file");

}

//查询算法

int algorithm = DbSearcher.BTREE_ALGORITHM; //B-tree

//DbSearcher.BINARY_ALGORITHM //Binary

//DbSearcher.MEMORY_ALGORITYM //Memory

try {

DbConfig config = new DbConfig();

DbSearcher searcher = new DbSearcher(config, dbPath);

//define the method

Method method = null;

switch ( algorithm )

{

case DbSearcher.BTREE_ALGORITHM:

method = searcher.getClass().getMethod("btreeSearch", String.class);

break;

case DbSearcher.BINARY_ALGORITHM:

method = searcher.getClass().getMethod("binarySearch", String.class);

break;

case DbSearcher.MEMORY_ALGORITYM:

method = searcher.getClass().getMethod("memorySearch", String.class);

break;

}

DataBlock dataBlock = null;

if ( Util.isIpAddress(ip) == false ) {

System.out.println("Error: Invalid ip address");

}

dataBlock = (DataBlock) method.invoke(searcher, ip);

return dataBlock.getRegion();

} catch (Exception e) {

e.printStackTrace();

}

return null;

}

public static void main(String[] args) throws Exception{

System.err.println(getCityInfo("220.248.12.158"));

}

}

运行结果如下：
