1. Replace the proxy IP: If the proxy IP is unavailable or blocked, you can try to replace the proxy IP. The proxy IP can be obtained through the API provided by the proxy provider or manually, and tested and screened. In the choice of proxy ip providers, it is necessary to provide a large number of ip pools and national regional nodes, which is more stable in use.
2. Check the proxy server status: If the proxy server fails or the network fluctuates, you can check the proxy server status and network status, and try to reconnect or replace the proxy server. Ip connectivity can be verified in batches through proxy ip online detection websites.
3. Check the settings of agent IP address and port number: If the settings of agent IP address and port number are wrong, you can check their correctness and make corresponding changes and tests.
4. Use anti-crawler technology: If the target website uses anti-crawler technology, some anti-crawler technologies can be used to bypass protection. You can bypass the anti-crawler strategy by using multiple proxy IPS, simulating browser behavior, pretending HTTP requests, etc.
5. Check Python program code: If Python crawler has errors, you can check the code logic, grammar and missing modules, and make corresponding debugging and modification. Debugging tools and logging techniques can be used to help diagnose problems and solve errors.
