How to automatically log into a website using Selenium with Chrome in C++

A guide on using Selenium with ChromeDriver in C++ to automatically log into a website. The article explains how to set up Selenium and ChromeDriver and the steps to log in to a specific website.

This article will guide you on how to use Selenium and ChromeDriver in C++ to automatically log into a website. Selenium automates browser actions like entering login credentials, clicking buttons, and navigating through websites.

C++ Code:

#include <iostream>
#include <webdriverxx/browsers/chrome.h>
#include <webdriverxx/webdriver.h>
#include <webdriverxx/wait.h>

using namespace webdriverxx;

int main() {
    // Initialize ChromeDriver
    WebDriver driver = Start(Chrome());

    // Navigate to the login page
    driver.Navigate("https://example.com/login");

    // Find input elements and enter login information
    driver.FindElement(ByName("username")).SendKeys("myusername");
    driver.FindElement(ByName("password")).SendKeys("mypassword");

    // Click the login button
    driver.FindElement(ByName("login")).Click();

    // Wait until the login is successful (can check URL or specific elements)
    Wait(driver, 10).Until([&driver]() {
        return driver.CurrentUrl() == "https://example.com/dashboard";
    });

    std::cout << "Login successful!" << std::endl;

    // Close the browser
    driver.Quit();
    return 0;
}

Detailed explanation:

1. #include <webdriverxx/browsers/chrome.h>: Library to control Chrome in Selenium.
2. WebDriver driver = Start(Chrome());: Initializes WebDriver with ChromeDriver.
3. driver.Navigate("https://example.com/login");: Navigates to the login page.
4. driver.FindElement(ByName("username")).SendKeys("myusername");: Enters the username into the input field named "username."
5. driver.FindElement(ByName("password")).SendKeys("mypassword");: Enters the password into the input field named "password."
6. driver.FindElement(ByName("login")).Click();: Clicks the login button.
7. Wait(driver, 10).Until([&driver]() {...});: Waits until the login process is complete by checking the URL.
8. driver.Quit();: Closes the browser after completion.

System requirements:

• C++ with Selenium WebDriver support (webdriverxx is a C++ library).
• ChromeDriver must be installed and configured to match the Chrome browser version.

How to install the libraries needed to run the above C++ code:

1. Download ChromeDriver from the official site.
2. Add webdriverxx to your C++ project.
3. Configure Selenium WebDriver to work with your Chrome version.

Tips:

• Ensure your ChromeDriver version matches your Chrome browser version.
• Use Wait to make sure the page is fully loaded before performing further actions.
• Secure your login credentials by storing them safely.
