和風天氣獲取天氣相關資料

和風天氣api說明地址： http://www.heweather.com/documents/api/s6
專案需要用到天氣的資料來做測試，所以學習了一下和風天氣這個平臺的使用方法，個人覺得還是很全面的。
使用之前需要自己在和風天氣平臺上面註冊一個使用者，然後點選控制器複製一下自己的key，後面會用到。
程式碼：
我獲取的就是今天明天和後天三天的天氣加上pm2.5，看過開發文件就知道pm2.5是在另外一個api上面，所以我就需要兩個api介面
// 介面地址 private String API = "https://free-api.heweather.com/s6/weather?key=加上你自己的key&location="; // 獲取Pm25的介面地址 private String getPm25URL = "https://free-api.heweather.com/s6/air/now?key=加上你自己的key&location=";
介面的形式也很簡單，就是
https://free-api.heweather.com/s6/weather?key=key&location=
需要注意的是：https://free-api.heweather.com/s6/weather?key= 這一段，不是所有人都是一樣的，，就是你自己需要哪種資料就去找對應的api，因為我自己就是去看別人的程式碼然後提示，某個屬性不存在，，233，然後key也是每個人不一樣的，key和location都是必須的值。location是中文的話需要處理亂碼。只需要處理location。
Java程式碼：
因為這個是為了測試不同地方的資料是否一致然後又不能開車到那個地方去，所以需要輸入地名，然後可以輸入的地名平臺上面也有，http://www.heweather.com/documents/city
