在企业代理背后使用 Selenium RemoteWebDriver

Question

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

被测试的应用程序位于代理之外，可以从 BrowserStack 自由访问。

这个 Using Selenium RemoteWebDriver Behind Corporate proxy (Java) stackoverflow 问题提出了同样的问题，但我无法遵循已接受的答案。

Answer 1

我设法根据链接的 stackoverflow 问题中接受的答案得到一些工作，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:[email protected]/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);
    }
}

Answer 2

添加 Andrew 上面的答案，为了使其与 Appium 一起工作，更改

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

到

HttpCommandExecutor executor = new HttpCommandExecutor(MobileCommand.commandRepository, url, factory);

Answer 3

我稍微修改了 Andrew Sumner 的解决方案，并删除了一些解决方案，以防像我这样的人想要通过 Fiddler 快速汇集其 WebDriver 流量以查看流量。

import java.net.MalformedURLException;
import java.net.URL;
import java.util.HashMap;

import org.apache.http.HttpHost;
import org.apache.http.impl.client.HttpClientBuilder;
import org.openqa.selenium.ie.InternetExplorerOptions;
import org.openqa.selenium.remote.CommandInfo;
import org.openqa.selenium.remote.HttpCommandExecutor;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.remote.http.HttpClient;
import org.openqa.selenium.remote.http.HttpClient.Factory;
import org.openqa.selenium.remote.internal.ApacheHttpClient;

public class ProxiedRemoteExample {
    private static final String PROXY_HOST = "localhost";
    private static final int PROXY_PORT = 8888;

    public ProxiedRemoteExample() throws MalformedURLException {
        InternetExplorerOptions ieOptions = new InternetExplorerOptions();
        RemoteWebDriver driver = new RemoteWebDriver(new HttpCommandExecutor(new HashMap<String, CommandInfo>(),
                new URL("http://localhost:5555/"), new Factory() {
                    private HttpClientBuilder builder;
                    {
                        builder = HttpClientBuilder.create();
                        builder.setProxy(new HttpHost(PROXY_HOST, PROXY_PORT));
                    }
                    @Override
                    public HttpClient createClient(URL url) {
                        return new ApacheHttpClient(builder.build(), url);
                    }

                }), ieOptions);
    }

}

Answer 4

与

org.seleniumhq.selenium:selenium-java:4.0.0-beta-3

我必须通过以下方式应用代理设置：

• 配置异步 http 客户端以使用代理设置
  • 在

    ahc.properties

    文件夹下创建

    org/asynchttpclient/config

    文件
  • 文件内容：

    org.asynchttpclient.useProxyProperties = true

• 配置 JVM 代理属性
  • System.getProperties().setProperty("http.proxyHost", "yourProxyHost")
  • System.getProperties().setProperty("http.proxyPort", "yourProxyPort")

Answer 5

在

v4.0.0-alpha-7

之后，http客户端的OkHttp实现已被删除。

但是在重读安德鲁的答案后，我找到了一种设置代理的简单方法：

var url = new URL("Your grid endpoint like browserstack or saucelabs");
var proxy = new java.net.Proxy(java.net.Proxy.Type.HTTP,
                    new InetSocketAddress("Your proxy", 8080));
var executor = new HttpCommandExecutor(ClientConfig.defaultConfig().baseUrl(url).proxy(proxy));
var driver = new RemoteWebDriver(executor, browserOptions); 

Answer 6

对于使用 Selenium 和 Java 并希望在 RemoteWebdriver 中添加身份验证代理的人。 我测试过，它对我有用。希望它可以节省您的时间。

DesiredCapabilities capabilities = new DesiredCapabilities();
    Proxy proxy = new Proxy();
    proxy.setHttpProxy(proxyItem);
    proxy.setSslProxy(proxyItem);
    proxy.setFtpProxy(proxyItem);
    proxy.setSocksUsername(userProx);
    proxy.setSocksPassword(passProx);
    proxy.setAutodetect(false);
    proxy.setProxyType(Proxy.ProxyType.MANUAL);
    capabilities.setCapability(CapabilityType.PROXY, proxy);
    RemoteWebDriver.builder();
    WebDriver driver = RemoteWebDriver.builder()
            .oneOf(chromeOptions)
            .address(new URI("http://localhost:4444/wd/hub"))
            .setCapability(CapabilityType.PROXY, proxy)
            .build();
    AddHasAuthentication addHasAuthentication = new AddHasAuthentication();
    addHasAuthentication.getImplementation(
                    capabilities, new RemoteExecuteMethod((RemoteWebDriver) driver))
            .register(UsernameAndPassword.of(userProxy, passProxy));
    driver.get("https://www.whatismyip.com");
