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.
Here's a simple example using the new DevTools protocol (CDP) available from Selenium 4 (this code uses the Beta-4 version and CDP for Chrome 91 )
:
import org.openqa.selenium.devtools.DevTools;
import org.openqa.selenium.devtools.v91.network.*;
:
DevTools devTools = ((ChromiumDriver) driver).getDevTools();
devTools.createSession();
devTools.send(Network.enable(Optional.empty(), Optional.empty(), Optional.empty()));
devTools.addListener(Network.requestWillBeSent(), entry -> {
System.out.println("Request (id) URL : (" + entry.getRequestId() + ") "
+ entry.getRequest().getUrl()
+ " (" + entry.getRequest().getMethod() + ")");
});
devTools.addListener(Network.responseReceived(), entry -> {
System.out.println("Response (Req id) URL : (" + entry.getRequestId() + ") "
+ entry.getResponse().getUrl()
+ " (" + entry.getResponse().getStatus() + ")");
});
driver.get("someurl"); // on so on ...
RemoteWebDriver, instead of calling ((ChromiumDriver) driver).getDevTools() you'll need to call ((HasDevTools) new Augmenter().augment(driver)).getDevTools() to get the devtools.You can get this done using LoggingPreferences and ChromeOptions
imports
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.logging.LogEntries;
import org.openqa.selenium.logging.LogEntry;
import org.openqa.selenium.logging.LogType;
import org.openqa.selenium.logging.LoggingPreferences;
import org.openqa.selenium.remote.CapabilityType;
Here We get Json String which contain data about the in log records. I use json-simple library to convert the received json String to JSONObject.
LoggingPreferences preferences = new LoggingPreferences();
preferences.enable(LogType.PERFORMANCE, Level.ALL);
ChromeOptions option = new ChromeOptions();
option.setCapability(CapabilityType.LOGGING_PREFS, preferences);
option.setCapability("goog:loggingPrefs", preferences);
option.addArguments();
System.setProperty("webdriver.chrome.driver", "chrome_driver_path");
ChromeDriver chromeDriver = new ChromeDriver(option);
chromeDriver.manage().window().maximize();
this.driver = chromeDriver;
driver.get("website_url");
LogEntries logs = driver.manage().logs().get(LogType.PERFORMANCE);
for (LogEntry entry : logs) {
JSONParser parser = new JSONParser();
JSONObject jsonObject = null;
try {
jsonObject = (JSONObject) parser.parse(entry.getMessage());
} catch (ParseException e) {
e.printStackTrace();
}
JSONObject messageObject = (JSONObject) jsonObject.get("message");
System.out.println(messageObject.toJSONString());
// You can do the required processing to messageObject
}
You can filter the type of network calls from logs using type (XHR, Script, Stylesheet) in the json String.
for (LogEntry entry : logs) {
if(entry.toString().contains("\"type\":\"XHR\"")) {
}
}
