I'm new to JavaScript and Vue.js, and I'm having trouble accessing an api using Vue.js. The API I'm trying to access has JSON that looks like this:
{
"coord": {
"lon": -88.99,
"lat": 40.51
},
"weather": [
{
"id": 800,
"main": "Clear",
"description": "clear sky",
"icon": "01n"
}
],
"base": "stations",
"main": {
"temp": 2.09,
"pressure": 1022.3,
"humidity": 69,
"temp_min": 2.09,
"temp_max": 2.09,
"sea_level": 1052.03,
"grnd_level": 1022.3
},
"wind": {
"speed": 12.66,
"deg": 205.502
},
"clouds": {
"all": 0
},
"dt": 1482203059,
"sys": {
"message": 0.186,
"country": "US",
"sunrise": 1482239741,
"sunset": 1482273134
},
"id": 4903780,
"name": "Normal",
"cod": 200
}
The API link on it's own works, but I do not think I'm accessing it when I run the program. Even when I don't try and parse the JSON and just display all the data collected from the api my variable is still empty. So, I must be doing something wrong to access the api. Also, after accessing the api, will parsing it like this work: for example, to access the tag "temp" => "data.main.temp"
var weather = new Vue({
el: '#weather',
data: {
getTemp: ''
},
created: function () {
this.fetchData();
},
methods: {
fetchData: function () {
this.$http.get('api.openweathermap.org/data/2.5/weather?q=Normal&units=imperial&APPID=MYAPPID'),
function (data) {
this.getTemp = data.main.temp;
}
}
}
})
;

When developing most projects using Vue.js, there’ll be a need to fetch or consume data from an API. This is used to make the front-end interact with the back-end of the application. The fetched data can then be consumed on the front-end of the application. What is an API?
Developers frequently fetch data from an API that returns data in the JSON format, which they integrate into front-end applications. Vue.js is a great fit for consuming these kinds of APIs.
Add API call to Vue.js Component You will now edit the ‘script.js’ file to add the API call to the Vue.js component. Before that, you must decide on the API. The choice of API is dependent on the application that you are building, or the API functionality that you are relying upon to be fulfilled by the API.
Let’s create a basic Vue application. We’ll build a single HTML page with some mocked-up data that we will eventually replace with live data from the API. We’ll use Vue.js to display this mocked data. For this first step, we’ll keep all of the code in a single file.
I see the problem with scope of this, scope of this changes inside $http.get black, you need to make following changes:
methods: {
fetchData: function () {
var vm = this
this.$http.get('api.openweathermap.org/data/2.5/weather?q=Normal&units=imperial&APPID=MYAPPID'),
function (data) {
vm.getTemp = data.main.temp;
}
}
}
