Here’s how to handle proxy authentication in Selenium 4 with Java: 1. Set Up Proxy with Authentication: Use `org.openqa.selenium.Proxy` to configure the proxy 2. Embed Credentials: Add the credentials in the proxy URL: ```java Proxy proxy = new Proxy(); proxy.setHttpProxy("username:password@proxyhost:port"); proxy.setSslProxy("username:password@proxyhost:port"); ``` 3. Attach to Driver: Add the proxy to your browser’s options: ```java ChromeOptions options = new ChromeOptions(); options.setCapability("proxy", proxy); WebDriver driver = new ChromeDriver(options); ``` -
Hello I'm working in one software company, when I open any browser I have to provide my proxy login to browse it. I have used this above code in my automation it is showing "Not found" error.

Fayaz To perform local mapping of a file in Charles with Selenium in BrowserStack automation, you can follow these steps: 1. Install Charles on your machine. 2. Start Charles and connect to the internet. 3. Open BrowserStack and create a new session. 4. In the BrowserStack session, select the Selenium option and enter the URL of the application that you want to test. 5. In the Selenium script, add the following code to perform local mapping of the file: ``` import requests import json def local_mapping(url, local_file): """Performs local mapping of a file in Charles. Args: url: The URL of the file to be mapped. local_file: The path to the local file to be mapped. """ request = requests.get(url) response = request.json() for item in response['mappings']: if item['url'] == url: item['local'] = local_file requests.post(url, json=response) if __name__ == '__main__': url = 'example.com/file.txt' local_file = '/tmp/file.txt' local_mapping(url, local_file) ``` 6. Run the Selenium script. 7. Charles will now map the file from the URL to the local file. 8. You can now test the application as usual. Here are some things to keep in mind when performing local mapping of a file in Charles with Selenium in BrowserStack automation: * The file that you want to map must be accessible from the machine where Charles is running. * The path to the local file must be absolute. * The local file must exist. * The URL of the file must be accessible from the internet. * The Selenium script must be able to access the Charles proxy. I hope this helps
Hi Raghav. Im trying to run it at the end but this is the error im facing:Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: net::ERR_PROXY_CONNECTION_FAILED (Session info: chrome=120.0.6099.110). how do i resolve it?
Leela The error message org.openqa.selenium.WebDriverException: unknown error: net::ERR_PROXY_CONNECTION_FAILED indicates that your Selenium script is unable to connect to the internet due to a proxy connection failure. Here are some possible solutions you can try: 1. Check your proxy settings: If you are using a proxy: Verify that the proxy settings are correct, including the hostname, port, username, and password. Ensure the proxy server is up and running. Try disabling the proxy and see if the script works without it. This will help you determine if the issue is indeed related to the proxy. If you are not using a proxy: Make sure your computer is connected to the internet and that the firewall is not blocking the connection. Check for any network connectivity issues or restrictions on your network. 2. Update your ChromeDriver: Make sure you are using the latest version of ChromeDriver that is compatible with your Chrome browser version. Download the appropriate version from the official ChromeDriver download page: chromedriver.chromium.org/downloads. 3. Set browser capabilities: You can try setting the proxy capability in your Selenium code to explicitly configure the proxy settings. This might be helpful if the automatic proxy detection is not working properly. Refer to the documentation of your specific WebDriver for details on how to set capabilities. Turn on verbose logging in your WebDriver to get more detailed information about the connection attempt. Check the browser console for any additional error messages that might be related to the proxy connection. Review online resources and forums for similar errors encountered with Selenium and proxy connections. By trying these steps and providing more information, you should be able to identify the cause of the net::ERR_PROXY_CONNECTION_FAILED error and resolve it in your Selenium script.
yes, you can use with Selenium. Using Node.js or JavaScript with Selenium is a popular choice for web automation testing. Selenium provides bindings for multiple programming languages, including JavaScript, which allows you to write automated tests using JavaScript or Node.js Using JavaScript or Node.js with Selenium provides a flexible and powerful combination for web automation testing. It allows you to leverage the capabilities of Selenium WebDriver while utilizing the features and ecosystem of JavaScript or Node.js.
Hi Ekta When using Selenium to automate web testing, you may encounter a proxy authentication popup that prompts you to enter a username and password. Here's how you can handle it: Create a new Firefox profile with proxy settings and save it to your local machine. Launch Firefox using the new profile that you just created. Use Selenium WebDriver to navigate to the website that requires proxy authentication. When the proxy authentication popup appears, use Selenium to switch to the alert box. Use the switchTo() method to switch to the alert box. Use the sendKeys() method to enter the username and password in the fields provided. Use the accept() method to click the OK button and submit the credentials. Here is some sample code to handle proxy authentication popup using Selenium in Java: FirefoxOptions options = new FirefoxOptions(); FirefoxProfile profile = new FirefoxProfile(); profile.setPreference("network.proxy.type", 1); profile.setPreference("network.proxy.http", "proxy_host"); profile.setPreference("network.proxy.http_port", "proxy_port"); profile.setPreference("network.proxy.ssl", "proxy_host"); profile.setPreference("network.proxy.ssl_port", "proxy_port"); options.setProfile(profile); WebDriver driver = new FirefoxDriver(options); driver.get("yourwebsite.com"); Alert alert = driver.switchTo().alert(); alert.sendKeys("your_username" + Keys.TAB + "your_password"); alert.accept(); This code launches Firefox with a new profile that has proxy settings, navigates to the website, switches To set proxy authentication for Chrome in Selenium, you can use ChromeOptions to add the necessary arguments. Here is an example: // set the proxy server and credentials String proxyServer = "proxy.example.com:8080"; String proxyUser = "username"; String proxyPass = "password"; // create ChromeOptions instance ChromeOptions options = new ChromeOptions(); // add the arguments to set the proxy server and credentials options.addArguments("--proxy-server=" + proxyServer); options.addArguments("--proxy-auth=" + proxyUser + ":" + proxyPass); // create WebDriver instance with ChromeOptions WebDriver driver = new ChromeDriver(options); In this example, we set the proxyServer variable to the hostname and port of the proxy server, and the proxyUser and proxyPass variables to the username and password for proxy authentication. Then, we create a ChromeOptions instance and add the necessary arguments using addArguments(). Finally, we create a ChromeDriver instance with the ChromeOptions object. With this configuration, when Chrome launches, it will automatically use the proxy server with the specified credentials.

public static void main(String[] args) {
// Start BrowserMob Proxy
BrowserMobProxy proxy = new BrowserMobProxyServer();
proxy.start(0);
// Configure Selenium to use the proxy
Proxy seleniumProxy = new Proxy();
seleniumProxy.setHttpProxy("localhost:" + proxy.getPort());
ChromeOptions options = new ChromeOptions();
options.setProxy(seleniumProxy);
WebDriver driver = new ChromeDriver(options);
proxy.newHar("capture");
// Navigate and trigger POST request
driver.get("your-url.com");
driver.findElement(By.id("your-button-id")).click(); // Adjust selector
// Capture and print POST payload
proxy.getHar().getLog().getEntries().stream()
.filter(entry -> "POST".equals(entry.getRequest().getMethod()))
.forEach(entry -> System.out.println("Payload: " + entry.getRequest().getPostData().getText()));
// Clean up
driver.quit();
proxy.stop();
}
}
Key Points
Proxy Setup: Configures Selenium to route through BrowserMob Proxy
Navigate and Capture: Triggers POST request and filters for POST entries to print payload.
Adjust the URL and element selector as necessary

Launch Firefox using the new profile that you just created.
Use Selenium WebDriver to navigate to the website that requires proxy authentication.

WebDriver driver = new FirefoxDriver(options);

This code launches Firefox with a new profile that has proxy settings, navigates to the website, switches
To set proxy authentication for Chrome in Selenium, you can use ChromeOptions to add the necessary arguments. Here is an example:
// set the proxy server and credentials
String proxyServer = "proxy.example.com:8080";
String proxyUser = "username";
String proxyPass = "password";
// create ChromeOptions instance
ChromeOptions options = new ChromeOptions();
// add the arguments to set the proxy server and credentials
options.addArguments("--proxy-server=" + proxyServer);
options.addArguments("--proxy-auth=" + proxyUser + ":" + proxyPass);
// create WebDriver instance with ChromeOptions
WebDriver driver = new ChromeDriver(options);
In this example, we set the proxyServer variable to the hostname and port of the proxy server, and the proxyUser and proxyPass variables to the username and password for proxy authentication.
Then, we create a ChromeOptions instance and add the necessary arguments using addArguments(). Finally, we create a ChromeDriver instance with the ChromeOptions object.
With this configuration, when Chrome launches, it will automatically use the proxy server with the specified credentials.
Hi Raghav, how to setup proxy for selenium manager ( without using Webdriver manager). I am getting TCP connection error while working with selenium manager.
Hi Rohit, To set up a proxy for Selenium without using a webdriver manager, you will need to configure the proxy settings in the code that creates the browser instance
Example:
/*
from selenium import webdriver
proxy = "proxy.example.com:8080"
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--proxy-server={}".format(proxy))
# Create the browser instance
browser = webdriver.Chrome(chrome_options=chrome_options)
*/
This sets up a proxy for the browser to use when making requests. The --proxy-server argument is used to specify the proxy server to use. The argument value is in the format ://:. Replace proxy.example.com:8080 with the IP and port of your proxy
In case your proxy requires authentication you will need to add the authentication details as well in the above settings.
