Scraping flight information quickly using proxy IP is a complex and skillful task. To do this efficiently and legally, you need to understand how to set up and manage proxy IPs, as well as how to write and optimize your scraping programs. The following is a detailed guide covering the steps from selecting a proxy service to performing scraping tasks.

Choose the right proxy service

Proxy type

Residential proxy: Uses a real residential IP address, which is more anonymous and not easily detected and blocked by the target website.

Data center proxy: Fast, but easily identified as a proxy, need to be used with caution.

Mobile proxy: Uses the IP address of a mobile network, which is the most anonymous, but the cost is higher.

Choose a provider

Choose a reputable proxy service provider to ensure the quality and stability of the proxy IP. Service providers that can be considered include lunaproxy, Piaproxy, etc.

Configure proxy IP

Manual configuration

Manually set the proxy IP address and port in your scraping script.

Use a library or tool

Use a scraping library like Scrapy, Selenium, BeautifulSoup, etc., which usually supports proxy configuration.

Use multithreading and asynchronous IO to improve crawling efficiency

In order to improve crawling efficiency, you can use technologies such as multithreading and asynchronous IO to access multiple target websites concurrently. Through multithreading technology, multiple requests can be initiated at the same time; and asynchronous IO can avoid blocking and waiting for responses, thereby improving the overall response speed. These technologies can effectively improve crawling efficiency and shorten crawling time.

Regularly update the proxy IP pool

Since the proxy IP may be blocked or invalidated by the target website, the proxy IP pool needs to be updated regularly. You can replace the invalid IP by purchasing or obtaining a new proxy IP for free to maintain the stability and availability of the proxy IP pool.
