如何从公司代理后面通过 RemoteWebDriver 连接到 Selenium 网格，例如 BrowserStack？

被测应用程序在代理之外，可从 BrowserStack 自由访问。

这Using Selenium RemoteWebDriver behind corporate proxy (Java) stackoverflow 问题问了同样的问题，但我无法遵循已接受的答案。

最佳答案

我设法根据链接的 stackoverflow 问题中接受的答案得到了一些工作，这是我的实现，以防其他人遇到同样的问题:

示例

import java.net.InetAddress;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.UnknownHostException;
import java.util.HashMap;
import java.util.Map;

import org.apache.http.HttpHost;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.NTCredentials;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.client.HttpClientBuilder;
import org.openqa.selenium.remote.CommandInfo;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.HttpCommandExecutor;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.remote.http.HttpClient.Factory;

public class Example {
    public RemoteWebDriver connectViaProxy(DesiredCapabilities caps) {
        String proxyHost = "?";
        int proxyPort = 8080;
        String proxyUserDomain = "?";
        String proxyUser = "?";
        String proxyPassword = "?";

        URL url;

        try {
            url = new URL("http://bsuser:bspassword@hub.browserstack.com/wd/hub");
        } catch (MalformedURLException e) {
            throw new RuntimeException(e.getMessage(), e);
        }

        HttpClientBuilder builder = HttpClientBuilder.create();

        HttpHost proxy = new HttpHost(proxyHost, proxyPort);

        CredentialsProvider credsProvider = new BasicCredentialsProvider();

        credsProvider.setCredentials(new AuthScope(proxyHost, proxyPort), new NTCredentials(proxyUser, proxyPassword, getWorkstation(), proxyUserDomain));

        if (url.getUserInfo() != null && !url.getUserInfo().isEmpty()) {
            credsProvider.setCredentials(new AuthScope(url.getHost(), (url.getPort() > 0 ? url.getPort() : url.getDefaultPort())), new UsernamePasswordCredentials(url.getUserInfo()));
        }

        builder.setProxy(proxy);
        builder.setDefaultCredentialsProvider(credsProvider);

        Factory factory = new MyHttpClientFactory(builder);

        HttpCommandExecutor executor = new HttpCommandExecutor(new HashMap<String, CommandInfo>(), url, factory);

        return new RemoteWebDriver(executor, caps);
    }

    private String getWorkstation() {
        Map<String, String> env = System.getenv();

        if (env.containsKey("COMPUTERNAME")) {
            // Windows
            return env.get("COMPUTERNAME");         
        } else if (env.containsKey("HOSTNAME")) {
            // Unix/Linux/MacOS
            return env.get("HOSTNAME");
        } else {
            // From DNS
            try
            {
                return InetAddress.getLocalHost().getHostName();
            }
            catch (UnknownHostException ex)
            {
                return "Unknown";
            }
        }
    }
}

MyHttpClientFactory

import java.net.URL;

import org.apache.http.impl.client.HttpClientBuilder;
import org.openqa.selenium.remote.internal.ApacheHttpClient;

public class MyHttpClientFactory implements org.openqa.selenium.remote.http.HttpClient.Factory {
    final HttpClientBuilder builder; 

    public MyHttpClientFactory(HttpClientBuilder builder) {
        this.builder = builder;
    }

    @Override
    public org.openqa.selenium.remote.http.HttpClient createClient(URL url) {
        return new ApacheHttpClient(builder.build(), url);
    }
}
