Solving reCaptcha Using Selenium and Capsolver Extension
In this blog, we'll guide you through the process of setting up Selenium with the Capsolver extension to solve reCaptcha v2. This method can also be applied to other types of captchas.
1. Installing Selenium and Required Components
First, you need to install Selenium and other necessary components. You can do this using npm:
npm install selenium-webdriverMake sure you have the appropriate drivers for the browser you intend to use (e.g., ChromeDriver for Google Chrome, GeckoDriver for Firefox).
2. Configuring the Capsolver Extension
Download the Capsolver extension from here. Unzip it into the ./CapSolver.Browser.Extension directory at the root of your project.
The extension offers various settings, including automatic captcha solving, proxy support, and more. These settings are located in ./assets/config.json. Here's an example of the configuration:
json
{
"apiKey": "YourApiKey",
"useCapsolver": true,
"useProxy": false,
"proxyType": "http",
"hostOrIp": "",
"port": "",
"proxyLogin": "",
"proxyPassword": "",
"enabledForBlacklistControl": false,
"blackUrlList": [],
"enabledForRecaptcha": true,
"enabledForRecaptchaV3": true,
"enabledForcaptcha": true,
"enabledForcaptcha": true,
"reCaptchaMode": "token",
"captchaMode": "click",
"reCaptchaDelayTime": 0,
"captchaDelayTime": 0,
"reCaptchaRepeatTimes": 10,
"reCaptcha3RepeatTimes": 10,
"captchaRepeatTimes": 10,
"captchaRepeatTimes": 10
}Insert your API key in the apiKey field in ./assets/config.json. You can find your API key on the Capsolver page.
For this example, we'll use the reCaptchaMode set to token, but you can also use click mode for reCaptcha.
3. Setting Up Selenium to Solve reCaptcha with Capsolver Extension
First, you need to set up Selenium WebDriver and configure it to use the Capsolver extension. Here's an example using ChromeDriver:
javascript
const { Builder } = require('selenium-webdriver');
const chrome = require('selenium-webdriver/chrome');
const path = require('path');
(async function solveCaptcha() {
let options = new chrome.Options();
options.addArguments(`--load-extension=${path.join(__dirname, 'CapSolver.Browser.Extension')}`);
let driver = await new Builder()
.forBrowser('chrome')
.setChromeOptions(options)
.build();
try {
// Navigate to the page with reCaptcha
await driver.get('https://www.google.com/recaptcha/api2/demo');
// Wait for the captcha solver button and click it
await driver.wait(until.elementLocated(By.css('#recaptcha-anchor-label')), 10000);
await driver.findElement(By.css('#recaptcha-anchor-label')).click();
// Add additional steps as per your requirement
} finally {
await driver.quit();
}
})();Full Code:
javascript
const { Builder, By, until } = require('selenium-webdriver');
const chrome = require('selenium-webdriver/chrome');
const path = require('path');
(async function solveCaptcha() {
let options = new chrome.Options();
options.addArguments(`--load-extension=${path.join(__dirname, 'CapSolver.Browser.Extension')}`);
let driver = await new Builder()
.forBrowser('chrome')
.setChromeOptions(options)
.build();
try {
await driver.get('https://site.example');
await driver.wait(until.elementLocated(By.css('#recaptcha-anchor-label')), 10000);
await driver.findElement(By.css('#recaptcha-anchor-label')).click();
} finally {
await driver.quit();
}
})();And that's it! You have successfully solved reCaptcha v2 using the Capsolver Extension and Selenium. To solve other types of captchas, simply follow the same steps and adjust accordingly.
