I have been struggling with how to add query string parameters to my URL. I couldn't make it work until I realized that I needed to add ? at the end of my URL, otherwise it won't work. This is very important as it will save you hours of debugging, believe me: been there...done that.
Below, is a simple API Endpoint that calls the Open Weather API and passes APPID, lat and lon as query parameters and return weather data as a JSON object. Hope this helps.
//Load the request module
var request = require('request');
//Load the query String module
var querystring = require('querystring');
// Load OpenWeather Credentials
var OpenWeatherAppId = require('../config/third-party').openWeather;
router.post('/getCurrentWeather', function (req, res) {
var urlOpenWeatherCurrent = 'http://api.openweathermap.org/data/2.5/weather?'
var queryObject = {
APPID: OpenWeatherAppId.appId,
lat: req.body.lat,
lon: req.body.lon
}
console.log(queryObject)
request({
url:urlOpenWeatherCurrent,
qs: queryObject
}, function (error, response, body) {
if (error) {
console.log('error:', error); // Print the error if one occurred
} else if(response && body) {
console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
res.json({'body': body}); // Print JSON response.
}
})
})
Or if you want to use the querystring module, make the following changes
var queryObject = querystring.stringify({
APPID: OpenWeatherAppId.appId,
lat: req.body.lat,
lon: req.body.lon
});
request({
url:urlOpenWeatherCurrent + queryObject
}, function (error, response, body) {...})
