Couch Tuner Proxy

Connecting to a Selenium Hub via a corporate proxy can be challenging, as the proxy may require authentication or have specific settings that need to be configured. To connect to the Selenium Hub through a corporate proxy, you'll need to configure the proxy settings in your Selenium client and Hub.

Here's a step-by-step guide on how to set up a Selenium Hub and client with corporate proxy settings:

Configure the Selenium Hub:

First, you need to configure the Selenium Hub to use the corporate proxy. You can do this by modifying the Hub's configuration file (usually hub.yml or hub.json) and adding the proxy settings.

For example, if you're using the hub.yml file, add the following configuration:

proxy:
  type: http
  httpProxy: http://username:[email protected]:port
  nonProxyHosts: localhost, 127.0.0.1, .example.com

Replace username, password, proxy.example.com, and port with the appropriate values for your corporate proxy. The nonProxyHosts setting specifies a list of hosts that should not use the proxy.

Configure the Selenium client:

Next, configure the Selenium client to use the corporate proxy. You can do this by setting the proxy settings in your WebDriver configuration.

For example, in Python with the Chrome WebDriver, you can configure the proxy as follows:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.proxy import Proxy, ProxyType

proxy = Proxy()
proxy.proxy_type = ProxyType.MANUAL
proxy.http_proxy = "http://username:[email protected]:port"
proxy.ssl_proxy = "http://username:[email protected]:port"

chrome_options = Options()
chrome_options.add_argument("--proxy-server=%s" % proxy.proxy)

driver = webdriver.Chrome(options=chrome_options)
driver.get('your_url')

# Rest of your code

driver.quit()

Replace username, password, proxy.example.com, and port with the appropriate values for your corporate proxy.

Start the Selenium Hub and connect the client:

Start the Selenium Hub and connect the client to the Hub using the appropriate configuration settings.

For example, if you're using the hub.yml file, start the Hub with the following command:

selenium-server-standalone jar hub.yml

Connect the client to the Hub using the appropriate configuration settings. For example, in Python, you can connect the client to the Hub as follows:

from selenium import webdriver
from selenium.webdriver.remote.webdriver import WebDriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

desired_caps = DesiredCapabilities.CHROME
desired_caps['proxy'] = {
    'httpProxy': 'http://username:[email protected]:port',
    'ftpProxy': 'http://username:[email protected]:port',
}

driver = WebDriver(desired_caps=desired_caps)
driver.get('your_url')

# Rest of your code

driver.quit()

Replace username, password, proxy.example.com, and port with the appropriate values for your corporate proxy.

By following these steps, you should be able to connect to a Selenium Hub via a corporate proxy and use the Selenium client to interact with webpages.

If you can't proxy requests in Scrapy:

- Verify correct proxy configuration in Scrapy settings.
- Confirm proxy functionality with external tools.
- Check for typos or errors in your code and settings.
- Ensure proxy authentication details are correct.
- Test with a direct internet connection to isolate the issue.
- Check for IP blocking by the target website.
- Confirm proper configuration of the HttpProxyMiddleware.
- Use Scrapy logging to inspect requests and responses.
- Ensure your proxy supports HTTPS if needed.
- Test with a single, static proxy for simplicity.
- Keep Scrapy and dependencies up to date.
- Consider using middleware libraries like scrapy-rotating-proxies.

Every proxy server is of the type 168.1.1.1:8080, where the first part before the colon is the IP address of the remote computer through which the connection is made. The second part (after the colon, in this case 8080) is the port number through which your equipment will connect to that very remote server.

The first thing you need to do to use a proxy in your browser is to make the necessary settings. In Google Chrome browser, go to "Network" and then find and click on "Change proxy settings". In the "Internet properties" window that opens, go to "Connection" and click on the "Network settings" button at the bottom. When a new window opens, check the "Use proxy server for local connections" box and the "Do not use proxy server for local addresses" box. Enter the proxy port and IP address in the corresponding fields, close the window and click "OK".

Data parsing in most cases refers to the collection of technical or other information. For example, a local proxy server can be used for parsing "log data". That is, information about the work of the site, the application, which in the future will be useful for developers to find and fix various bugs.
