ip okhttp 设置_隧道代理ip - Java okhttp 接入指南

示例代码

import okhttp3.*;

import java.io.IOException;

import java.net.InetSocketAddress;

import java.net.Proxy;

import java.util.concurrent.TimeUnit;

public class ProxyTest {

// 代理服务器

final static String proxyHost = "dyn.horocn.com";

final static Integer proxyPort = 50000;

// 代理隧道验证信息

// 用户名和密码可到隧道代理订单页面获取：https://proxy.horocn.com/user-tunnel-orders

// 其中，订单号为用户名

final static String proxyUser = "username";

final static String proxyPass = "password";

static OkHttpClient client = null;

static {

Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyHost, proxyPort));

Authenticator proxyAuthenticator = new Authenticator() {

public Request authenticate(Route route, Response response) {

String credential = Credentials.basic(proxyUser, proxyPass);

return response.request().newBuilder()

.header("Proxy-Authorization", credential)

.build();

}

};

client = new OkHttpClient().newBuilder()

.followRedirects(false)

.followSslRedirects(false)

.connectTimeout(5, TimeUnit.SECONDS)

.readTimeout(5, TimeUnit.SECONDS)

.proxy(proxy)

.proxyAuthenticator(proxyAuthenticator)

.connectionPool(new ConnectionPool(5, 1, TimeUnit.SECONDS))

.build();

}

public static Response doGet() throws IOException {

// 要访问的目标页面

String targetUrl = "https://www.baidu.com/";

Request request = new Request.Builder()

.url(targetUrl)

.build();

return client.newCall(request).execute();

}

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

System.setProperty("jdk.http.auth.tunneling.disabledSchemes", "");

Response response1 = doGet();

System.out.println("GET请求返回结果：");

assert response1.body() != null;

System.out.println(response1.body().string());

}

}

测试环境

openjdk-12.0.2

okhttp-3.14.9

注意点

1、出现错误：unexpected end of stream on unknown

请检查下用户名和密码是否准确

请检查下订单是否过期
