Scrapy Rotating Proxies

It means that the address of such a server changes periodically. This is useful if the user wants to be as anonymous as possible when surfing the web.

Both on a PC and on modern cell phones, a built-in utility that is responsible for working with network connections, provides the ability to set up a connection through a proxy server. You just need to enter the IP-address for connection and the port number. In the future all traffic will be redirected through this proxy. Accordingly, the provider will not block it.

In web development, the style.left property refers to the left offset position of an element within its containing element. The value of style.left is a string that represents the distance from the element's left edge to the left edge of its containing element. This distance can be specified using various units, such as pixels, percentages, or other length units.

When you retrieve style.left in JavaScript, you get a string representation of this distance. For example:

var element = document.getElementById('exampleElement');
var leftValue = element.style.left; // Returns a string like "10px" or "50%"

To perform numerical calculations or comparisons with the left offset, you might want to parse this string and extract the numeric value. Parsing involves removing the unit (e.g., "px" or "%") and converting the remaining part to a numeric value.

Here's an example of how you can parse the style.left value in JavaScript:

var element = document.getElementById('exampleElement');
var leftValue = element.style.left;

// Parse the numeric value
var parsedLeft = parseFloat(leftValue);

// Now parsedLeft is a numeric value representing the left offset
console.log(parsedLeft);

By parsing the value, you can use it in mathematical operations or make comparisons. Keep in mind that parsing might return NaN (Not a Number) if the value is not a valid number, so it's important to handle such cases appropriately.

If you can't download images in Scrapy:

- Check the image pipeline configuration in settings.py.
- Verify HTTPS compatibility and install the certifi package if necessary.
- Confirm the correctness of XPath or CSS selectors for image URLs.
- Ensure image URLs are in the correct format; log URLs for inspection.
- Handle redirects by setting REDIRECT_ENABLED = True.
- Check and set appropriate HTTP headers in your Scrapy spider.
- Adjust the CONCURRENT_REQUESTS setting to avoid server restrictions.
- Verify correct configuration of the ImagesPipeline.
- Inspect the downloaded images in the specified IMAGES_STORE directory.
- Implement exception handling in your spider to catch download errors.
