When using automated scripts to crawl content from other people's websites, there is a real risk of being discovered or blocked by the target website. Here are some strategies you can try, but please note that these methods cannot guarantee complete avoidance of problems and may violate the terms of use of the target website, so please be sure to comply with relevant laws and regulations and the terms of use of the website. 1. **Set a reasonable crawling frequency**: Avoid sending a large number of requests in a short period of time. You can reduce the risk of being detected by setting a reasonable request interval. 2. **Use a proxy**: Using a proxy server can hide your real IP address and reduce the risk of being blocked. However, this may still violate the policy of the target website. 3. **Randomize User-Agent**: Randomize the User-Agent string in the request to simulate different browsers and devices to reduce the possibility of being identified as a robot (bot). 4. **Set request headers**: Add common browser request headers, such as Referer and Accept, to make the request look more like normal browsing from a single user. 5. **Simulate human behavior**: Randomize the time and order of requests to simulate the normal browsing behavior of human users rather than a fixed pattern. 6. **Handle CAPTCHAs**: If a website uses CAPTCHAs to prevent automated access, consider using OCR technology or a third-party solution, but this can be complicated. 7. **Monitor blocking**: Regularly check the effectiveness of your scripts and monitor if they are blocked so that you can make adjustments in a timely manner. 8. **Follow robots.txt specifications**: Check the robots.txt file of the target website and comply with the website's crawling policies and restrictions. 9. **Avoid accessing sensitive or frequently changing pages**: Try to avoid crawling pages that change frequently or sensitive information to reduce the risk of being discovered. 10. **Consider legal APIs**: Many websites provide public APIs for developers to use, which is a more legal and secure way to crawl data. It is important to note that although the above strategies can reduce the risk of being discovered to a certain extent, the website's terms of use and data privacy regulations must be respected in any case.
