我正在尝试使用 JS Fetch API 获取 5 天的天气预报，尽管我按照文档中的说明传递了 cnt=5，但我仍然只获取当前天气。我错过了什么吗？
fetch('https://api.openweathermap.org/data/2.5/weather?q=' + city+ '&appid=' + key+'&cnt=5')
我已经做了足够的研究，但无法弄清楚我到底在哪里做错了。感谢您的帮助。
const key = '**** Your API Key Here ****';
function weatherForecast(city) {
fetch('https://api.openweathermap.org/data/2.5/weather?q=' + city+ '&appid=' + key+'&cnt=5')
.then(function(resp) {
return resp.json()
})
.then(function(data) {
console.log('--->'+(JSON.stringify(data)));
drawWeather(data);
})
.catch(function() {
// catch any errors
});
}
function drawWeather( d ) {
var celcius = Math.round(parseFloat(d.main.temp)-273.15);
var fahrenheit = Math.round(((parseFloat(d.main.temp)-273.15)*1.8)+32);
var description = d.weather[0].description;
document.getElementById('description').innerHTML = description;
document.getElementById('temp').innerHTML = fahrenheit + '°';
document.getElementById('location').innerHTML = d.name+' '+d.sys.country;
}
//Event Listeners on button click
document.addEventListener("DOMContentLoaded", () => {
// Handling button click
document.querySelector(".button-search").addEventListener("click", () => {
const searchedCity = document.querySelector('.text-search');
console.log(searchedCity.value);
if(searchedCity.value){
weatherForecast(searchedCity.value);
}
})

最佳答案
对于 5 天的天气预报，您需要调用 /forecast 而不是 /weather 端点。
例子:
https://api.openweathermap.org/data/2.5/forecast?q=New%20York&appid=<your-api-key>&cnt=5
关于javascript - openweathermap 上的 5 天天气预报未给出预期结果，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/63222396/
