我无法在我的 Selenium 项目中设置 BrowserMob 代理。就像BrowserMob Proxy github 页面中描述的那样,我在我的代码中导入了它:

public class DriverBase {
    public WebDriver driver;
public BrowserMobProxy proxy;

    @Before
    public void setUp() {
    proxy = new BrowserMobProxyServer();
        proxy.start(0);

     Proxy sproxy = ClientUtil.createSeleniumProxy(proxy);

        DesiredCapabilities caps=new DesiredCapabilities();
        caps.setCapability(CapabilityType.PROXY, sproxy);
 driver = new ChromeDriver(caps);

我从 browsermob-core 中排除了 slf4j 传递依赖并添加了 slf4j-jdk14,以便服务器可以启动(最初它不能)。

 <dependency>
        <groupId>net.lightbody.bmp</groupId>
        <artifactId>browsermob-core</artifactId>
        <version>2.1.5</version>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>org.seleniumhq.selenium</groupId>
                <artifactId>selenium</artifactId>
                 </exclusion>
                    <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-api</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>jcl-over-slf4j</artifactId>
            </exclusion>
            <exclusion>
                <groupId>com.google.guava</groupId>
                <artifactId>guava</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-jdk14</artifactId>
        <version>1.8.0-beta0</version>
    </dependency>

我还手动添加了 com.google.guava 19.0,因为服务器不是从最新的 guava 版本开始的。

    <dependency>
        <groupId>com.google.guava</groupId>
        <artifactId>guava</artifactId>
        <version>19.0</version>
    </dependency>

在我的测试类中,我只启动浏览器:

public class TrafficTest extends DriverBase{

 @Test
 public void testTraffic()    {    
    driver.navigate().to("http://liveexpert.ru");
}

浏览器启动,但无法打开站点或无法访问 Internet。最初的 browsermob-core maven 设置甚至无法启动服务器或浏览器。当前设置引发错误:

    java.lang.NoSuchMethodError: com.google.common.net.HostAndPort.getHost()Ljava/lang/String;

这是完整的日志

是否有任何解决方法来设置驱动程序以访问互联网?

到目前为止,解决方案是使用guava 22.0

番石榴的 18,19 版本导致了这个问题:

java.lang.NoSuchMethodError: com.google.common.net.HostAndPort.getHost()

为什么在这里解释

最新版本的 guava 23.x 摆脱了这个问题,但反过来又引发了另一个问题:

java.lang.IllegalAccessError: tried to access method com.google.common.util.concurrent.SimpleTimeLimiter.<init>(Ljava/util/concurrent/ExecutorService;)V from class org.openqa.selenium.net.UrlChecker
