Capture network traffic using selenium webdriver java 4.0v

Question

I would like to capture the network traffic generated in a Chromedriver window. I have found out that it can be done using selenium 4.0 DevTools utility but I can´t find how to or a good documentation.

https://www.selenium.dev/selenium/docs/api/java/org/openqa/selenium/devtools/DevTools.html

Is there an easiest way to do? Thanks

Using Selenium 4 you can get requests URL and Response URLs and more.

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>4.0.0</version>
</dependency>

<dependency>
    <groupId>io.github.bonigarcia</groupId>
    <artifactId>webdrivermanager</artifactId>
    <version>4.3.1</version>
</dependency>

Using this snippet you will get all requests and responses.

    @BeforeEach
    public void setUp() {
        WebDriverManager.chromedriver().setup();
        this.chromeDriver = new ChromeDriver();
        devTools = chromeDriver.getDevTools();
        devTools.createSession();
    }

    @Test
    public void getRequestsAndResponseUrls() throws InterruptedException {
        devTools.send(new Command<>("Network.enable", ImmutableMap.of()));
;
        devTools.addListener(Network.responseReceived(), l -> {
            System.out.print("Response URL: ");
            System.out.println(l.getResponse().getUrl());
        });
        devTools.addListener(Network.requestWillBeSent(), l -> {
            System.out.print("Request URL: ");
            System.out.println(l.getRequest().getUrl());
        });

        chromeDriver.get("https://edition.cnn.com/");

        // While Thread.sleep you you will see requests and responses appearing in console. 
        Thread.sleep(10000);
    }

Enjoy.
