Utilizing Proxies with Colly
Proxies can be easily integrated with Colly to facilitate anonymous and scalable web scraping. Colly supports the configuration of proxy servers, which can be rotated to avoid IP-based blocks and throttling.
Steps to Integrate Proxies:
- Initialization: Initialize Colly with its default settings.
- Proxy Configuration: Set up the proxy settings within Colly.
- Rotation: Employ logic to rotate proxies as needed.
- Testing: Validate the setup to ensure proxies are used for requests.
Code Example:
goc := colly.NewCollector()
rps, _ := proxy.RoundRobinProxySwitcher("http://127.0.0.1:8080", "http://127.0.0.2:8080")
c.SetProxyFunc(rps)
