Add header in Selenium

[sjoshid]

Hi,
Im very close to using this but there's only one thing stopping me. In Firefox, when I want to send a request with a header. Without this header, my request is going to fail.

I tried this:

final ProfilesIni pi = new ProfilesIni();
final FirefoxProfile profile = pi.getProfile("default");
profile.setPreference("browser.download.folderList",
      2); // 0: Desktop, 1: Downloads, 2: Custom Location
final Path abs = downloadedFilePath.toAbsolutePath();
profile.setPreference("browser.download.dir", abs.toString());

final String commonPassword = repProperties.getCommonPassword();
final String usernamePassword = username + ":" + commonPassword;
final String encodedString = Base64.getEncoder().encodeToString(usernamePassword.getBytes());

// These prefs dont work. 
/*profile.setPreference("modifyheaders.headers.count", 1);
profile.setPreference("modifyheaders.headers.action0", "Add");
profile.setPreference("modifyheaders.headers.name0", "Authorization");
profile.setPreference("modifyheaders.headers.value0", "Basic " + encodedString);
profile.setPreference("modifyheaders.headers.enabled0", true);
profile.setPreference("modifyheaders.config.active", true);
profile.setPreference("modifyheaders.config.alwaysOn", true);*/

// Neither do these. 
profile.setPreference("modheader.headers.count", 1);
profile.setPreference("modheader.headers.action0", "Add");
profile.setPreference("modheader.headers.name0", "Authorization");
profile.setPreference("modheader.headers.value0", "Basic " + encodedString);
profile.setPreference("modheader.headers.enabled0", true);
profile.setPreference("modheader.headers.config.active", true);
profile.setPreference("modheader.headers.config.alwaysOn", true);

final FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.setCapability("acceptInsecureCerts", true);
//firefoxOptions.setHeadless(true); sj_todo remove uncomment
firefoxOptions.setProfile(profile);

logger.debug("Creating reports at {}", abs);
final FirefoxDriver webDriver = new FirefoxDriver(firefoxOptions);
webDriver.installExtension("path-to-xpi");
return webDriver;

Another way is to load the modheader profile (that has the header I need) on startup. But I cant find a way to import automatically on startup either.

Any suggestions?

Thanks.

Hi, please take a look at the Java Selenium section here: https://modheader.com/docs/advanced/selenium-webdriver

You just need something like this:

FirefoxDriver driver = new FirefoxDriver();
driver.installExtension(Paths.get("firefox-modheader/modheader.xpi"));
// The URL query parameters are the request header name and value to add
driver.get("https://webdriver.modheader.com/add?test=ModHeader%20Test");
new WebDriverWait(driver, Duration.ofSeconds(500)).until(ExpectedConditions.titleIs("Done"));

Thanks for the reply.

I did see this in the docs. But didnt realize it applied here. Btw what is this url https://webdriver.modheader.com/add?test=ModHeader%20Test? Can you give a little more details on how it works?

We wont be having internet connection and even if we did, Im not comfortable calling this URL.

The way it works is that the extension will intercept requests matching webdriver.modheader.com, and extract the URL query parameters from there, then add them as request headers to the current profile. It does not require internet connection. However, if the extension is not properly installed, then it will hit a static website telling you to read the ModHeader webdriver docs.

Alternatively, you can use the Firefox add-on URL directly. Something like moz-extension://1ace738d-0b76-46c8-87f5-10afab79e397/add.html?test=ModHeader%20Test. However, I am not sure if this ID is stable, and this URL is different on Firefox vs Chrome, so using the webdriver.modheader.com domain is easiest.

Hi, somehow it is only work with WebDriverManager.firefoxdriver().setup(); FirefoxDriver driver = new FirefoxDriver(); driver.installExtension(Paths.get("firefox-modheader/modheader.xpi")); driver.get("https://webdriver.modheader.com/add?test=ModHeader%20Test");

        However, if I want to include firefoxOptions, then it won't work. 
        `WebDriverManager.firefoxdriver().setup();
        FirefoxProfile fprofile = new FirefoxProfile();
        fprofile.addExtension(new File("firefox-modheader/modheader.xpi"));
        FirefoxOptions foptions = new FirefoxOptions();
        foptions.addArguments("--incognito");
        foptions.addArguments("--start-maximized");
        foptions.addArguments("--window-size=1920,1080");
        foptions.addArguments("--disable-notifications");
        foptions.addArguments("--disable-dev-shm-usage");
        foptions.addArguments("--ignore-ssl-errors=yes");
        foptions.addArguments("--ignore-certificate-errors");
        foptions.setProfile(fprofile);
        driver = new FirefoxDriver(foptions);`

and if after driver.get("https://webdriver.modheader.com/add?test=ModHeader%20Test");

How do we navigate to the page we want next? let's say google.com
