我正在尝试从HTML源中读取以下输出(源每30分钟更新一次):
{"un":"Watt","tm":"2015-11-21T15:57:00","dt":60,"val":[" 510"," 504"," 504"," 498"," 498"," 498"," 498"," 498"," 498"," 492"," 492"," 504"," 522"," 522"," 516"," 528"," 528"," 534"," 522"," 522"," 504"," 498"," 498"," 486"," 486"," 540"," 528"," 528"," 534"," 528",null]}
但我无法让它发挥作用。
是否有可能以某种方式表明结果是一个json文件,或者我是否需要某人为此创建一个ETL插件?
有一种简单的方法吗?
