在企业代理后面使用Selenium RemoteWebDriver [英] Using Selenium RemoteWebDriver behind corporate proxy

问题描述

如何通过RemoteWebDriver从公司代理服务器后面连接到诸如BrowserStack之类的selenium网格？

How can I connect to a selenium grid such as BrowserStack via RemoteWebDriver from behind a corporate proxy?

正在测试的应用程序位于代理服务器之外，可以从BrowserStack免费访问。

The application under test is outside the proxy and freely accessible from BrowserStack.

此使用企业代理（Java）背后的Selenium RemoteWebDriver stackoverflow问题提出了同样的问题，但我无法按照接受的答案。

This Using Selenium RemoteWebDriver behind corporate proxy (Java) stackoverflow question asked the same question but I couldn't follow the accepted answer.

推荐答案

我设法根据链接的stackoverflow问题中的接受答案得到了一些工作，这是我的实现，以防其他人是坚持同样的问题：

I managed to get something working based on the accepted answer in the linked stackoverflow question, here's my implementation in case anyone else is stuck on the same problem:

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:[e-mail]/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);
    }
}
