离线版IP归属地查询

news2024/11/25 18:56:09

这里简单介绍一下Ip2regionSearcher是什么？

ip2region 是准确率 99.9% 的 IP 地址定位库，0.0x毫秒级查询，提供了 Java、PHP、C、Python、Node.js、Golang、C#、Rust、Lua的查询绑定和 Binary、B树、内存三种查询算法！

Setp1：导入依赖

<dependency>
    <groupId>net.dreamlu</groupId>
    <artifactId>mica-ip2region</artifactId>
    <version>2.5.6</version>
</dependency>
<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>5.8.11</version>
</dependency>

提示：Ip2regionSearcher的和hutool工具包依赖包，这里导入hutool为了后期利用获取IP工具类

Setp2：编写测试接口

import cn.hutool.extra.servlet.ServletUtil;
import lombok.RequiredArgsConstructor;
import net.dreamlu.mica.ip2region.core.Ip2regionSearcher;
import net.dreamlu.mica.ip2region.core.IpInfo;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;

/**
 * <p>
 * 测试控制器
 * <p>
 *
 * @className: XController
 * @author: BertXie
 * @create: 2023-01-09 11:40
 */

@RestController
@RequiredArgsConstructor
public class XController {

    private final Ip2regionSearcher searchSearcher;

    @GetMapping("/ip")
    public String getHomeLocation(HttpServletRequest request) {
        IpInfo ipInfo = searchSearcher.memorySearch(ServletUtil.getClientIP(request));
        return ipInfo != null ? ipInfo.getCity() : "未知星球";
    }

}

注意：这里注入了Ip2regionSearcher对象，并使用了memorySearch方法，会返回一个IP详情对象，还用到了Hutool工具的获取IP的方法ServletUtil.getClientIP
