 node-red 擷取 環境部環境資料開放平台開放資料 UVI PM2.5

   先向環境部註冊 取得 金鑰 

=======================================================

var rawdata =msg.payload;

var site_number=rawdata.length;

var site_array=[];

var i;

for (i=0; i<site_number;i++)

{

    site_array[i]=rawdata[i].sitename;

}

msg.payload=site_array;

 

flow.set("uvi_sitename",site_array);

return msg;

=======================================================

get  Sitename  all records function 的寫法

 j變數的用法

var rawdata =context.global.uvi_records;

var site_number=rawdata.length;

var site_name=msg.payload;

var site_array=[];

var i;

var j=0;

for (i=0; i<site_number;i++)

{

    if (site_name==rawdata[i].sitename)

    {

      site_array[j]=rawdata[i];

      j=j+1;

    }

}

msg.payload=site_array;

 

flow.set("uvi_getdata",site_array);

return msg;

金鑰請修改成自己的
