IronWebScraper is a web scraping library for .NET that allows developers to efficiently extract data from websites. Using a proxy server with IronWebScraper is a common requirement to avoid IP bans or to scrape content as if you are coming from different geographical locations.
To use a proxy with IronWebScraper, you need to set the Proxy
property of the WebScraper
or Request
class. Below is an example of how to set up a proxy server in IronWebScraper:
- First, you need to install IronWebScraper by either downloading the DLL from the official website or using NuGet Package Manager. To install it via NuGet, you can run the following command in the NuGet Package Manager Console:
Install-Package IronWebScraper
- Once you have IronWebScraper installed, you can write C# code that sets up a proxy server. Here is an example of how to use a proxy in IronWebScraper:
using IronWebScraper;
class Program
{
static void Main(string[] args)
{
var scraper = new WebScraper();
// Set up the proxy server
scraper.Proxy = new HttpProxy("proxy_server_address", proxy_port, "username", "password");
// Or set up the proxy server without authentication
// scraper.Proxy = new HttpProxy("proxy_server_address", proxy_port);
// Define the scraping logic
scraper.OnResponse += (response) =>
{
// Process the response.Content with response.StatusCode, etc.
Console.WriteLine(response.Content);
};
// Start scraping
scraper.Request("http://example.com", Parse);
scraper.Start();
}
// Define the parse method
public static void Parse(Response response)
{
// Your parse logic here
}
}
Replace "proxy_server_address"
, proxy_port
, "username"
, and "password"
with the actual details of your proxy server. If your proxy server doesn't require authentication, you can use the constructor without the username and password parameters.
Please note the following points while using proxies:
- Make sure that the proxy you're using is reliable and supports the protocols required by the websites you intend to scrape.
- Be aware of the legal and ethical implications of web scraping and ensure you have the right to scrape the website and that you comply with its terms of service and robots.txt file.
- Some websites may still be able to detect that you are using a proxy and might block your requests.
IronWebScraper is a powerful tool, and when combined with proxies, it can help you scrape data from websites while minimizing the risks of being blocked or banned. Always use proxies responsibly and respect the target website's terms of service.
