Unable to get the network traces and the har file is empty.

[Sridhar Rajendran]

It is creating the har file, but it didn't capture any network traces. Could you please someone help on this?

Code:

package makemyhar;

import java.io.File;

import java.io.IOException;

import java.net.Inet4Address;

import java.net.UnknownHostException;

import org.openqa.selenium.Proxy;

import org.openqa.selenium.WebDriver;

import net.lightbody.bmp.client.ClientUtil;

import net.lightbody.bmp.core.har.Har;

import net.lightbody.bmp.proxy.CaptureType;

public class test {

public static WebDriver driver;

public static BrowserMobProxyServer proxy;

public static void main(String[] args) {

System.setProperty("webdriver.chrome.driver", "/Users/srajendran/Desktop/chromedriver");

proxy = new BrowserMobProxyServer();

proxy.setTrustAllServers(true);

proxy.start();

Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);

try {

String hostIp = Inet4Address.getLocalHost().getHostAddress();

System.out.println();

seleniumProxy.setHttpProxy(hostIp + ":" + proxy.getPort());

seleniumProxy.setSslProxy(hostIp + ":" + proxy.getPort());

} catch (UnknownHostException e) {

e.printStackTrace();

}

DesiredCapabilities seleniumCapabilities = DesiredCapabilities.chrome();

seleniumCapabilities.setCapability(CapabilityType.PROXY, seleniumProxy);

ChromeOptions options = new ChromeOptions();

driver = new ChromeDriver(options);

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

try {

proxy.newHar("swtestacademy");

driver.get("http://www.google.com");

try {

Thread.sleep(10000);

} catch (InterruptedException e) {

e.printStackTrace();

}

Har har = proxy.getHar();

System.out.println(har);

File harFile = new File("academy.har");

har.writeTo(harFile);

} catch (IOException ioe) {

ioe.printStackTrace();

}

driver.quit();

proxy.stop();

}

}
