Build a Price Tracker with Crawlee and Apify

说明与用途

使用 Crawlee for Python 和 Apify 构建价格追踪器的指南。涵盖设置爬虫、提取产品数据、在价格下降时发送电子邮件警报以及将解决方案部署到 Apify 云平台。

问题

Manually checking product prices is inefficient. Users need an automated way to monitor specific products for price drops and receive immediate notifications.

结果

A fully functional Apify Actor that scrapes product details, exports data in various formats, and sends email alerts when prices drop below a set threshold.

工作流

• Install Apify CLI and create a new project using the 'Python and Crawlee + BeautifulSoup' template.
• Configure the crawler to target a specific product URL (e.g., Raspberry Pi 5 on Central Computer).
• Implement CSS selectors to extract product name and price (handling currency symbols and data attributes).
• Define a price threshold and integrate the 'Send Email' Actor to trigger alerts when the price drops below the threshold.
• Authenticate with Apify using an API token to enable email sending capabilities.
• Test the script locally using 'apify run --purge'.
• Deploy the actor to the Apify cloud using 'apify push'.
• Configure the actor input and schedule runs in the Apify dashboard.
