node-red 擷取 環境部環境資料開放平台開放資料 UVI PM2.5

 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
