搞Java的必看!动态代理IP这么玩才专业

做数据采集的朋友都懂,用固定IP搞批量请求分分钟被封。今天手把手教你怎么用Java玩转动态代理,重点推荐咱们自家服务ipipgo的动态住宅代理,9000万+真实家庭IP随便换。

原生Java设置动态代理

直接上硬菜,System.setProperty这招最原始但有效。注意代理服务器要带鉴权的话,得自己搞个Authenticator:


// 设置全局代理(HTTP协议)
System.setProperty("http.proxyHost", "gateway.ipipgo.com");
System.setProperty("http.proxyPort", "30001");

// 带账号密码的写法
System.setProperty("http.proxyUser", "你的账号");
System.setProperty("http.proxyPassword", "动态密钥");

这种写法有个坑——只能全局生效。要是程序里有多线程任务,建议用连接级代理更灵活。

HttpClient玩转IP轮换

推荐用Apache HttpClient 4.5+版本,配合ipipgo的动态住宅套餐,代码这么写:


// 创建代理路由
HttpHost proxy = new HttpHost("dynamic.ipipgo.com", 31112);

// 配置请求参数
RequestConfig config = RequestConfig.custom()
    .setProxy(proxy)
    .setConnectTimeout(5000)
    .build();

// 带自动鉴权
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
    new AuthScope(proxy),
    new UsernamePasswordCredentials("账号", "密码"));

CloseableHttpClient client = HttpClients.custom()
    .setDefaultCredentialsProvider(credsProvider)
    .setDefaultRequestConfig(config)
    .build();

Here's the point!每次请求前调用ipipgo的API换IP,他们的接口响应速度控制在200ms以内,比市面上同类快30%不止。

Spring项目集成方案

在application.yml里加个配置项,用占位符方便不同环境切换:


ipipgo:
  proxy:
    enabled: true
    endpoint: rotator.ipipgo.com:443
    auth-type: dynamic-token

写个配置类自动装配,记得用@ConditionalOnProperty控制开关:


@Bean
@ConditionalOnProperty(name = "ipipgo.proxy.enabled", havingValue = "true")
public RestTemplate proxyRestTemplate() {
    HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
    factory.setHttpClient(createProxyClient());
    return new RestTemplate(factory);
}

A practical guide to avoiding the pit

测试过上百个项目,总结三个必看要点:

problematic phenomenon check the direction of the investigation Recommended Programs
突然大量407错误 1. 密钥过期时间
2. 账户并发超限
换ipipgo企业版套餐
响应时间超过2秒 1. 代理地域选择
2. 协议类型错误
Enabling the SOCKS5 protocol
IP Reuse 1. 会话保持设置
2. 更换策略错误
设置max-usage=50

Frequently Asked Questions

Q: Do I have to change my IP for each request?
A:看业务场景,爬虫建议5-10次换IP,抢购类业务必须每次更换。ipipgo的动态套餐支持两种模式自由切换

Q:遇到证书校验失败咋整?
A:在HttpClient里加这段绕过SSL验证(仅测试环境用):


SSLContext sslContext = new SSLContextBuilder()
    .loadTrustMaterial(null, (x509Certificates, s) -> true).build();

Why ipipgo?

咱家的动态住宅代理有三大绝活:
