????????最近在做數據分析平臺，那在做這個產品的時最需要的自然是測試數據，自己去構建行業測試數據比較麻煩，看到有同行產品的演示數據當然不能錯過。由于采集過程中使用到BeetleX.Http.Clients去抓取第三方的Https接口數據，所以順便記錄一下BeetleX.Http.Clients使用的方法。

????????首先構建一個控制臺程序，然后Nuget引用BeetleX.Http.Clients組件，引用后就可以干活了，組件提供一個HttpClient對象可以很方便的對webapi進行訪問，即使是調用https也無須添加任何配置即可完成。

????????接下來取一下https://console.bce.xxxx.com/sugar/的演示產品數據。

由于接口的調用需要一些訪問憑證信息，這些信息可以通過瀏覽器訪問獲取得到。

只需要在瀏覽器訪問一下就可以獲取到詳細的cookie和token信息，把這些信息添加到http的頭。配置好之后所有工作就簡單多了，在調用Post后根據自己需要解釋對應Body的數據即可。由于平臺沒做調用限制，沒過幾分鐘900多頁的數據就成功獲取下來
