求助大佬，点击刷新后天气地址更新了，但是天气信息没有跟新，并且跳出报错

这是JSON格式{ "code": "200", "updateTime": "2020-06-30T22:00+08:00", "fxLink": "http://hfx.link/2ax1", "now": { "obsTime": "2020-06-30T21:40+08:00", "temp": "24", "feelsLike": "26", "icon": "101", "text": "多云", "wind360": "123", "windDir": "东南风", "windScale": "1", "windSpeed": "3", "humidity": "72", "precip": "0.0", "pressure": "1003", "vis": "16", "cloud": "10", "dew": "21" }, "refer": { "sources": [ "QWeather", "NMC", "ECMWF" ], "license": [ "QWeather Developers License" ] }}
