如何在Apache HTTP Client 4中使用Socks 5代理？

我正在尝试创建通过 HC

发送HTTP请求的应用。我无法使用应用程序全局代理，因为应用程序是多线程的（我需要为每个实例使用不同的代理）。我没有发现HC4使用SOCKS5的示例。如何使用？

*HttpClient

回答：

SOCK是TCP / IP级别的代理协议，而不是HTTP。开箱即用不支持HttpClient。

可以使用自定义连接套接字工厂自定义HttpClient以通过SOCKS代理建立连接

更改为SSL而不是普通套接字

Registry<ConnectionSocketFactory> reg = RegistryBuilder.<ConnectionSocketFactory>create()
        .register("http", PlainConnectionSocketFactory.INSTANCE)
        .register("https", new MyConnectionSocketFactory(SSLContexts.createSystemDefault()))
        .build();
PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(reg);
CloseableHttpClient httpclient = HttpClients.custom()
        .setConnectionManager(cm)
        .build();
try {
    InetSocketAddress socksaddr = new InetSocketAddress("mysockshost", 1234);
    HttpClientContext context = HttpClientContext.create();
    context.setAttribute("socks.address", socksaddr);
    HttpHost target = new HttpHost("localhost", 80, "http");
    HttpGet request = new HttpGet("/");
    System.out.println("Executing request " + request + " to " + target + " via SOCKS proxy " + socksaddr);
    CloseableHttpResponse response = httpclient.execute(target, request, context);
    try {
        System.out.println("----------------------------------------");
        System.out.println(response.getStatusLine());
        EntityUtils.consume(response.getEntity());
    } finally {
        response.close();
    }
} finally {
    httpclient.close();
}

static class MyConnectionSocketFactory extends SSLConnectionSocketFactory {
    public MyConnectionSocketFactory(final SSLContext sslContext) {
        super(sslContext);
    }
    @Override
    public Socket createSocket(final HttpContext context) throws IOException {
        InetSocketAddress socksaddr = (InetSocketAddress) context.getAttribute("socks.address");
        Proxy proxy = new Proxy(Proxy.Type.SOCKS, socksaddr);
        return new Socket(proxy);
    }
}
