Axios Typescript, выборка из openweathermap api вызывает неверный запрос или ECONNREFUSED 127.0.0.1:80

Вопрос:

У меня возникли проблемы с подключением к openweathermaps API в моем приложении express,

 app.get("/", cors(), async (req, res) => { 
    const lat: number =   req.query.lat;
    const lon: number =   req.query.lon;
    if (lat amp;amp; lon) {
        const entry = cach.filter(e => e.lat === lat amp;amp; e.lon === lon);
        if (entry.some(e => (Date.now() - e.last_updated < 36000000))) {
            res.json(entry[0]);
        } else { // no entry found
            res.json(await getWeather(lat, lon));
        }

    }
    res.send("no location specified")
});
app.listen(PORT, function () {
    console.log(`App is listening on port ${PORT}`); //5000 by default
});
 

для извлечения данных я использую axios:

 async function getWeather(lat: number, lon: number) {
    try {
    const res = await axios({
        url:`http:api.openweathermap.org/data/2.5/weather?lat=${lat}amp;lon=${lon}amp;appid=${process.env.WAPI}`,
        method:"GET"
    });
    const data = res.data;
    ...
    catch (error){
        console.log(error)
    }

 

но ответ, который я получаю,:

Приложение прослушивает порт 5000 в ср. 09 дек. 2020 г. 15:22:21 GMT 0100 (по центральноевропейскому стандартному времени): http://localhost:5000/?lat=65.58415amp;lon=22.15465 : ПОЛУЧИТЬ запрос

указанный URL-адрес при вводе в браузер не вызывает проблем, у кого-нибудь есть какие-нибудь идеи?

Комментарии:

1. Привет, вы должны исправить свой URL с http:api... на http://api... (рассмотрите возможность использования https). Я думаю, что из-за этого axios интерпретирует ваш URL-адрес как относительный и пытается найти его локально там, где он не существует

2. Боже мой, я это полностью пропустил, Спасибо!
