This is project for scraping video metadata from Bilibili and processing the data into a MySQL database. My project Workflow [login to view URL] Initialization ([login to view URL]) Establishes a connection to the database and creates the video_stats table if it doesn't already exist. The video_stats table is designed to store various video metrics like views, likes, comments, and rankings. It has a foreign key relationship with the bv_numbers table, ensuring data integrity. [login to view URL] Number Collection ([login to view URL]) Scrapes the unique BV numbers (video IDs) from the Bilibili website using Selenium. Handles pagination and avoids duplicates by cross-referencing existing data in the bv_numbers table. [login to view URL] Data Fetching ([login to view URL]) Retrieves detailed video metrics for the collected BV numbers. Implements dynamic IP rotation to bypass request limits or bans. Inserts the fetched data into the video_stats table in batches for efficiency. [login to view URL] Orchestration ([login to view URL]) Coordinates the entire workflow using Python’s multiprocessing module. Runs the BV number scraper and video data fetcher concurrently. Monitors process health and restarts processes if they terminate unexpectedly. Enforces a maximum runtime for the script to prevent it from running indefinitely. [login to view URL] Cleaning ([login to view URL]) Resets the database by truncating the video_stats and bv_numbers tables, clearing all existing data but there are 2 issues when i try crawl the data by my own code. the first is errors during API calls or scraping. the IP of my crawler will be blocked, and I will no longer be allowed to access the website to obtain data. the second is As I get more and more videos to crawl, the more time it takes to crawl each time, and the interval between the data tracked at each time becomes larger, and I can't guarantee that it will be around 5 minutes.

Hi I see you're working on scraping Bilibili video metadata and processing the data into a MySQL database. I understand you're facing two main issues: IP blocking during API calls or scraping, and increased crawling time as more videos are added. To address these: 1. For IP blocking, you can implement more robust techniques like using rotating proxies, setting up a pool of proxy servers, or integrating services like ScraperAPI or ProxyCrawl. This will ensure that your crawler can avoid getting blocked by distributing the requests across different IP addresses. 2. Regarding the increased crawling time, it could be due to inefficient handling of concurrency or rate limiting. I recommend optimizing your scraping strategy by improving the parallelization of tasks using tools like `asyncio` or managing the load using a queue-based system. You can also implement a backoff strategy when the server starts limiting the requests, ensuring you stay within acceptable intervals. Would you like to discuss these solutions in more detail, or do you have any specific concerns you'd like me to focus on? I’d be happy to help you optimize this workflow. About me: I’m Usama Malik, a Full-Stack Developer with experience in Python scraping, Node.js, and database management. I have worked on similar automation and web scraping projects and am confident I can help solve these issues. Let’s schedule a quick call to discuss your requirements in more detail.
