Hello all,
I'm having an issue getting the correct parameters passing in my printWeather function for the Node.js challenge. The API I'm using to call the city name and weather ID is Open Weather Map - I'm using the docs found here: https://openweathermap.org/current#current_JSON
Currently, when running my code, I get the printWeather message "The temperature in undefined is undefined". I'm looking to have it return a message e.g. "The temperature in Toronto is 14 degrees C" or similar.
const https = require("https");
const http = require("http");
function printWeather(weather) {
message = `The temperature in ${weather.name} is ${weather.main.temp}.`;
console.log(message);
}
function getWeather(city) {
const request = http.get(`http://api.openweathermap.org/data/2.5/forecast?id=524901&APPID=03d21c74966bde3f834a355c42432b86`, response => {
let body = "";
response.on("data", chunk => {
body += chunk.toString();
});
response.on("end", () => {
// console.log(body);
//parse data
const weather = JSON.parse(body);
printWeather(weather);
//print data
});
});
};
getWeather();

Your code works apart from the line below. You are just referencing the wrong path in the JSON response.
let message = `The temperature in ${weather.city.name} is ${weather.list[0].main.temp}.`;
// 0 index of weather.list being the most recent measurement
If you want to get the weather for a specific city you will need to pass the city through to the get request URL.
