要转换为本地时间的原因是为了可以更改图像的背景。因此，最后我想输出12:00或20:00之类的时间。我的JSON看起来像：
{
"lat":52.37,"lon":4.89,"timezone":"Europe/Amsterdam","timezone_offset":7200,"current":{
"dt":1593619296,"sunrise":1593573770,"sunset":1593633935,"temp":20.09,"feels_like":13.21,"pressure":1006,"humidity":56,"dew_point":11.05,"uvi":6.73,"clouds":20,"visibility":10000,"wind_speed":10.3,"wind_deg":260,"weather":[
{
"id":801,"main":"Clouds","description":"few clouds","icon":"02d"
}
],"rain":{
}
},
那很好。只需运行摘要即可。
const api_res = {
"lat": 52.37,"lon": 4.89,"timezone": "Europe/Amsterdam","timezone_offset": 7200,"current": {
"dt": 1593619296,"sunrise": 1593573770,"sunset": 1593633935,"temp": 20.09,"feels_like": 13.21,"pressure": 1006,"humidity": 56,"dew_point": 11.05,"uvi": 6.73,"clouds": 20,"visibility": 10000,"wind_speed": 10.3,"wind_deg": 260,"weather": [{
"id": 801,"main": "Clouds","description": "few clouds","icon": "02d"
}],"rain": {}
}
}
function format_date(x) {
x = String(x);
if(x.length === 1) {
return "0"+x;
} else {
return x;
}
}
seconds_to_sunrise = api_res["current"]["sunrise"];
var d = new Date(0);
d.setUTCSeconds(seconds_to_sunrise);
console.log(format_date(d.getHours())+":00");,
如果我正确地找到了您的问题，则需要这样的东西（例如，您可以将其重构得更漂亮）：
const dt = new Date(weatherData.current.dt * 1000);
const sunrise = new Date(weatherData.current.sunrise * 1000);
const sunset = new Date(weatherData.current.sunset * 1000);
我们将秒数乘以1000，因为JS中的时间戳以毫秒为单位，而不是Unix OS的秒。
之后，您可以使用Date对象通过Date API获得所需的内容。我想，您想要.getHours()方法。
