前端如何自己開發快遞查詢api接口

快遞查詢接口是指快遞查詢網對外開放的應用程序接口，開發人員能夠通過調用該接口與快遞查詢網進行交互，並基於該接口開發自己的快遞查詢應用程序。

技術文檔請參考快遞鳥官網api：免費查詢快遞接口_100%安全保障_物流即時查詢API-快遞鳥
（一）接入流程：

1、登錄快遞鳥官網注冊頁面注冊快遞鳥賬號
網址：快遞單號查詢接口_電子面單_APIKey授權申請-快遞鳥賬號注冊
2、登錄快遞鳥用戶管理后台
網址：用戶登錄_快遞鳥API讓物流接口對接更簡單
接口說明
(1)、接口支持的消息接收方式為HTTP POST，請求方法的編碼格式(utf-8)：“application/x-www-form-urlencoded;charset=utf-8”。
(2)、指定的物流運單號選擇相應的快遞公司編碼，格式不對或則編碼錯誤都會返失敗的信息。如EMS物流單號應選擇快遞公司編碼（EMS）
(3)、 API測試地址：http://testapi.kdniao.cc:8081/api/dist
(4)、API正式地址：http://api.kdniao.cc/api/dist
(5)、定時推送新的物流信息
(6)、接口秘鑰申請：快遞鳥（http://www.kdniao.com/reg）
