Wsg Proxy

You cannot use a proxy server in Outlook (for security reasons). Therefore, it is possible to organize a local proxy with traffic forwarding through the port. Or you can use third-party tools such as ProxyCap.

To set up a proxy on your computer, you need to go through a simple procedure. If we're talking about Windows 10, you'll first need to open the "Settings" application and the "Network and Internet" section. Here, after opening the "Proxy Server" tab, find the column "Manual proxy server setup" just to the right and move the switch to the "On" position. Enter the IP address and the proxy port in the specified fields and click "Save".

Simply, in the connection properties of your PC or mobile device, you need to enter the data of the proxy server through which you will be connecting. In Windows, for example, this is done through "Settings", then "Network and Internet", and in the next window you should open the tab "Proxy server".

To pass a variable from Python to Selenium JavaScript, you can use the execute_script method provided by the WebDriver instance. This method allows you to execute custom JavaScript code within the context of the current web page. You can pass Python variables as arguments to the JavaScript code.

Here's an example using Python:

Install the required package:

pip install selenium

Create a method to execute JavaScript with a Python variable:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

def execute_javascript_with_python_variable(driver, locator, python_variable):
    element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located(locator))
    return driver.execute_script("return arguments[0] + arguments[1];", element.text + python_variable)

Use the execute_javascript_with_python_variable method in your test code:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Set up the WebDriver
driver = webdriver.Chrome()
driver.maximize_window()

# Navigate to the target web page
driver.get("https://www.example.com")

# Locate the element you want to interact with
locator = (By.ID, "element-id")

# Execute JavaScript with a Python variable
result = execute_javascript_with_python_variable(driver, locator, "Hello, World!")

# Print the result
print(result)

# Perform any additional actions as needed

# Close the browser
driver.quit()

In this example, we first create a method called execute_javascript_with_python_variable that takes a driver instance, a locator tuple containing the locator strategy and locator value, and a python_variable string containing the Python variable value. Inside the method, we use the WebDriverWait class to wait for the element to become visible and then call the execute_script method with the JavaScript code that concatenates the element's text and the Python variable.

In the test code, we set up the WebDriver, navigate to the target web page, and locate the element using the locator variable. We then call the execute_javascript_with_python_variable method with the driver, locator, and "Hello, World!" as input. The method returns the concatenated result, which we print in the console.

Remember to replace "https://www.example.com", "element-id", and "Hello, World!" with the actual URL, element ID or locator, and desired Python variable value.

In Scrapy, you can control the caching behavior of requests made by rules in your spider by adjusting the dont_cache attribute in the Rule object. The dont_cache attribute, when set to True, indicates that the requests matched by the rule should not be cached.

Here's an example of how you can use dont_cache in a CrawlSpider:

from scrapy.linkextractors import LinkExtractor
from scrapy.spiders import CrawlSpider, Rule

class MySpider(CrawlSpider):
    name = 'my_spider'
    allowed_domains = ['example.com']
    start_urls = ['http://example.com']

    rules = (
        # Example Rule with dont_cache set to True
        Rule(LinkExtractor(allow=('/page/')), callback='parse_page', follow=True, dont_cache=True),
    )

    def parse_page(self, response):
        # Your parsing logic for individual pages goes here
        pass

- The spider is defined as a CrawlSpider.
- The Rule is created with LinkExtractor to match URLs that contain '/page/' in them.
- The dont_cache=True attribute is set to True in the Rule, indicating that requests matched by this rule should not be cached.

By setting dont_cache to True, Scrapy will make sure that requests matched by this rule will be fetched without considering the cache. This is useful when you want to ensure that each request to the specified URLs results in a fresh response, bypassing any cached data.
