今天遇到一朋友一個問題，順手幫他寫了小工具，其實主要是因為泰國佛牌有一些驗證單位像是 薩瑪空(Samakon) 、G-Pra 、DD -Pra、 塔帕占( Thaprachan )等等
這些驗證單位的網站提供了佛牌的認證與詳細資訊，不過通常都需要手動輸入卡號來查詢。我發現 Samakon 的查詢系統是透過 HTTP POST 來發送請求，
因此決定使用 C# 來寫一個簡單的爬取工具。
1. 安裝 RestSharp ，現在習慣用這個處理 關於 http 爬取的部分
2.接下來就是程式碼的部分
我將這個工具分為兩個主要的函式：
GetSMKData - 這個函式會發送 HTTP POST 請求，並獲取 HTML 回應。
ParseSMKData - 使用 Regex 解析 HTML，提取關鍵資訊。

其他的就看你需要啥再自己取得，如果是 Console 因為有泰文的關係，記得 Console.OutputEncoding = Encoding.UTF8;
