课程名称：通过API Web抓取消费数据：Python，JavaScript 课程概述：本课程将指导学员使用Python和Django构建应用程序，转化API发送的数据，使应用程序充当客户端并消费数据。Web抓取是自动化收集结构化网页数据的过程，亦称为网页数据提取。Web抓取的主要应用场景包括价格监控、价格智能、新闻监控、潜在客户生成和市场研究等。一般来说，网页数据提取被希望利用海量公开网络数据以做出更聪明决策的人士和企业广泛使用。 如果你曾经从网站上复制粘贴信息，那你已经在微观层面上执行了和Web抓取器相同的功能。与手动提取数据的枯燥过程不同，Web抓取利用智能自动化技术，从互联网的无穷尽的领域中检索数百、数百万甚至数十亿的数据点。数据提取工具可以帮助自动化从其他网站提取信息的过程，精准高效，且能确保提取的数据整齐有序，便于分析和用于其他项目。 在电子商务领域，Web数据抓取被广泛用于竞争对手价格监控。它是品牌检查竞争对手产品和服务定价的唯一实际方式，使品牌能够微调自己的价格策略，保持竞争优势。同时，也可作为制造商确保零售商遵循产品定价指南的工具。市场研究机构和分析师依赖于Web数据提取来评估消费者情绪，通过跟踪在线产品评论、新闻文章和反馈信息。 在金融领域，数据提取的应用也非常广泛。数据抓取工具用于提取新闻故事中的洞察，以此信息指导投资策略。同样，研究人员和分析师依赖于数据提取来评估公司的财务健康状况。保险和金融服务公司可以从网络中挖掘丰富的替代数据，以为客户设计新产品和政策。 课程大纲：无
We build an application with Python and Django and use it to transform the data that an API sends, so our application is acting as a client and consuming the data.Web scraping is the process of collecting structured web data in an automated fashion. It's also called web data extraction. Some of the main use cases of web scraping include price monitoring, price intelligence, news monitoring, lead generation, and market research among many others.In general, web data extraction is used by people and businesses who want to make use of the vast amount of publicly available web data to make smarter decisions.If you've ever copied and pasted information from a website, you've performed the same function as any web scraper, only on a microscopic, manual scale. Unlike the mundane, mind-numbing process of manually extracting data, web scraping uses intelligent automation to retrieve hundreds, millions, or even billions of data points from the internet's seemingly endless frontier.Web data extraction - also widely known as data scraping - has a huge range of applications. A data scraping tool can help you automate the process of extracting information from other websites, quickly and accurately. It can also make sure the data you've extracted is neatly organized, making it easier to analyze and use for other projects.In the world of e-commerce, web data scraping is widely used for competitor price monitoring. It's the only practical way for brands to check the pricing of their competitors' products and services, allowing them to fine-tune their own price strategies and stay ahead of the game. It's also used as a tool for manufacturers to ensure retailers are compliant with pricing guidelines for their products. Market research organizations and analysts depend on web data extraction to gauge consumer sentiment by keeping track of online product reviews, news articles, and feedback.There's a vast array of applications for data extraction in the financial world. Data scraping tools are used to extract insight from news stories, using this information to guide investment strategies. Similarly, researchers and analysts depend on data extraction to assess the financial health of companies. Insurance and financial services companies can mine a rich seam of alternative data scraped from the web to design new products and policies for their customers.
