java如何使用代理IP

MAVEN引入如下依赖包：
<dependencies>

<dependency>

<groupId>cn.hutool</groupId>

<artifactId>hutool-all</artifactId>

<version>5.3.5</version>

</dependency>

<dependency>

<groupId>com.squareup.okhttp3</groupId>

<artifactId>okhttp</artifactId>

<version>4.7.1</version>

</dependency>

</dependencies>

复制下面代码，新建Package：com.demo --> 新建Java类：Main
package com.demo;
import cn.hutool.http.HttpUtil;
import okhttp3.*;
import java.io.*;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.util.Objects;
import java.util.concurrent.TimeUnit;
public class Main {
// 需要请求的目标网址
private static final String TARGET_URL = "目标网址";
// 提取链接
private static final String API_URL = "提取链接";
public static void main(String[] args) {
String result = HttpUtil.get(API_URL);
System.out.println("从接口获取回来:" + result.strip());
String proxyIp = result.strip();
try {
Proxies(TARGET_URL, proxyIp);
Thread.sleep(500);
} catch (Exception e) {
e.printStackTrace();
}
}
public static void Proxies(String urlString, String ipPort) {
try {
Response response = null;
try {
System.out.println("当前ip：" + ipPort);
String ip = ipPort.split(":")[0];
int port = Integer.parseInt(ipPort.split(":")[1]);
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(ip, port));
OkHttpClient httpClient = new OkHttpClient().newBuilder().proxy(proxy).connectTimeout(10, TimeUnit.SECONDS)
.build();
Request request = null;
request = (new Request.Builder().url(urlString).build());
response = httpClient.newCall(request).execute();
System.out.println("输出结果2：" + Objects.requireNonNull(response.body()).string());
} catch (IOException e) {
System.out.println("错误提示1");
e.printStackTrace();
}
} catch (Exception e) { System.out.println("错误提示2");
e.printStackTrace();
}
}
}
