近年來許多各式各樣的購物網站興起，網路購物成為多數人花錢消費的選擇，不管是電子產品、食品或是各類生活用品等等，幾乎都能在購物網站中完成購買，再加上不需要大費周章地到大型賣場，網路購物成為許多消費者的首要選擇；而在眾多的購物網站和商品品牌中，當消費者拿到兩者幾乎一模一樣或是功能相近的產品時，消費者通常都會以「價格」作為選擇的最終指標。 LINE APP是時下非常普遍多人使用的APP，不管是日常訊息傳送、影片分享、甚至是行動支付等應用，LINE APP帶給使用者們的方便讓我們幾乎不能一天不使用它。而LINEBOT是LINE推出的聊天機器人，在經過設計後便可以達成工程師或使用者希望得到的回應，不管是純粹聊天或是更加複雜的功能。 本研究目標是要以Python語言撰寫出一個能夠爬取購物網站之商品價格資訊的爬蟲程式，並以LINEBOT為使用者介面呈現。使用者只需要對聊天機器人傳送想要爬取的商品名稱，LINEBOT便會以回覆訊息的方式，給予使用者輸入之商品資訊與價格。

In recent years, many various shopping websites have emerged, and online shopping has become the choice for most people to spend money. Whether it is electronic products, food or all kinds of daily necessities, almost all purchases can be made on shopping websites. Coupled with the fact that there is no need to spend time and effort to go to large stores, online shopping has become the first choice for many consumers; and in many shopping websites and product brands, when consumers get the two that are almost identical or have similar functions When it comes to products, consumers usually use "price" as the final indicator of choice. LINE is a very common APP used by many people nowadays. Whether it is for daily messaging, video sharing, or even mobile payment..., the convenience that Line APP brings to users makes it almost impossible to not use it for a day. The LINEBOT is a chat robot launched by LINE. After being designed, it can achieve the response that engineers or users hope to get, whether it is pure chat or more complex functions. Our goal for thematic production is to build a crawler program based on the Python programming language that can crawl the commodity price information of shopping websites and present it with LINEBOT as the user interface. Users only need to send the name of the product they want to crawl to the chatbot, and LINEBOT will reply to the message and give the user the input product information and price.
