Browser-mob proxy does not capture network traffic using chrome driver

Question

I use this code to integrate a browser proxy with a dependency on maven net.lightbody.bmp browsermob-core 2.1.5

network requests don't capture it at all, I get this har file:

{
   "log":{
      "version":"1.2",
      "creator":{
         "name":"BrowserMob Proxy",
         "version":"2.1.0-beta-6-littleproxy",
         "comment":""
      },
      "pages":[
         {
            "id":"11",
            "startedDateTime":"2017-10-26T17:28:42.501+05:30",
            "title":"11",
            "pageTimings":{
               "comment":""
            },
            "comment":""
         }
      ],
      "entries":[],
      "comment":""
   }
}

Answer 1

I ran your code and you only need two changes, change

WebDriver driver = new ChromeDriver(options);

to

WebDriver driver = new ChromeDriver(cap);

And move browserMobProxy.newHar("11");before moving

browserMobProxy.newHar("11");
driver.get("http://www.lenskart.com");

The rest is all right. After you do this, Har is generated perfectly, as shown in the screenshot below

Answer 2

There are two problems in the code.

- selenium , . , - selenium :

Proxy seleniumProxy  = ClientUtil.createSeleniumProxy(browserMobProxy);

ChromeOptions options = new ChromeOptions();
options.addArguments("--ignore-certificate-errors");
options.setCapability(CapabilityType.PROXY, seleniumProxy);

WebDriver driver = new ChromeDriver(options);
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

-, browserMobProxy.newHar , :

browserMobProxy.newHar("11");

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

browserMobProxy.getHar().writeTo(new File("/Users/pankaj.katiyar/Desktop/Automation/Lenskart_Automation/har"));

driver.quit();
browserMobProxy.stop();
