Add Httpheader to selenium chrome webdriver in C#

Question

My C# code looks like this for creating chrome web driver, i wanted to add the custom HTTP headers to all my http requests.

ex: user-agent : Android

var service = ChromeDriverService.CreateDefaultService(@"c:\Chrome\");
var option = new ChromeOptions();
_driver = new ChromeDriver(service, option);

We have the way for firefox, as the link shows, but for chrome it does not work. https://eveningsamurai.wordpress.com/2013/11/21/changing-http-headers-for-a-selenium-webdriver-request/

Any help appreciated

I've been able to manage that using ModHeaders Chrome extension. Download the plugin CRX file and load it in your test Chrome instance.

var options = new ChromeOptions();
options.AddExtension("WebDrivers/modHeader_2_1_1.crx");

var driver = new ChromeDriver(options);

Then you can configure the plugin using the local storage as this is where the plugins stores its config too.

// set the context to access extension local storage
Configuration.driver.Navigate().GoToUrl("chrome-extension://idgpnmonknjnojddfkpgkljpfnnfcklj/icon.png");

Configuration.driver.ExecuteScript(
    "localStorage.setItem('profiles', JSON.stringify([{                " +
    "  title: 'Selenium', hideComment: true, appendMode: '',           " +
    "  headers: [                                                      " +
    "    {enabled: true, name: 'MY_HEADER', value: 'MY_VALUE', comment: ''}  " +
    "  ],                                                              " +
    "  respHeaders: [],                                                " +
    "  filters: []                                                     " +
    "}]));                                                             ");

And finally you can navigate to somewhere and check that the headers are loaded

    Configuration.driver.Navigate().GoToUrl("http://example.com/");
