selenium - 使用 BrowserMobProxy 进行硒测试时，Chrome 中的 ERR_EMPTY_RESPONSE

Question

我创建了从 Chrome 获取网络流量的简单方法：

 public void saveNetworkTraffic() {
    System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir") + "/bin/chromedriver");
    String sFileName = "networklog.xar";

    BrowserMobProxy proxy = new BrowserMobProxyServer();
    proxy.start(0);

    Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);

    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability(CapabilityType.PROXY, seleniumProxy);

    WebDriver driver = new ChromeDriver(capabilities);
    WebDriverRunner.setWebDriver(driver);

    proxy.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT);

    proxy.newHar("google.com");

    driver.get("http://google.com/");
    Har har = proxy.getHar();

    File harFile = new File(sFileName);
    try {
        har.writeTo(harFile);
    } catch (IOException ex) {
        System.out.println(ex.toString());
        System.out.println("Could not find file " + sFileName);
    }
}

当浏览器打开一个页面时，它会在这一步显示错误“ERR_EMPTY_RESPONSE”，driver.get("http://google.com/")而不是 Chrome 中通常的谷歌页面。我试图找出错误的原因，但根据https://github.com/lightbody/browsermob-proxy#using-with-selenium，我的代码应该可以正常工作。

Answer 1

添加此代码，尝试一下：

proxy.addFirstHttpFilterFactory(new ResponseFilterAdapter.FilterSource(new ResponseFilter() {
            @Override
            public void filterResponse(HttpResponse response, HttpMessageContents contents, HttpMessageInfo messageInfo) {}}, Integer.MAX_VALUE));

您的代码看起来不错，请尝试调整依赖项，例如：

        <dependency>
            <groupId>net.lightbody.bmp</groupId>
            <artifactId>browsermob-core</artifactId>
            <version>2.1.5</version>
        </dependency>
