从网站填充松果矢量数据库#

¥Populate a Pinecone vector database from a website

使用 n8n 抓取网站，将数据加载到 Pinecone，然后使用聊天工作流进行查询。此工作流使用 HTTP 节点 获取网站数据，使用 HTML 节点 提取相关内容，然后使用 Pinecone 矢量存储节点 将其发送到 Pinecone。

¥Use n8n to scrape a website, load the data into Pinecone, then query it using a chat workflow. This workflow uses the HTTP node to get website data, extracts the relevant content using the HTML node, then uses the Pinecone Vector Store node to send it to Pinecone.
