VueJS method for making an HTTP GET request

Attempting to make an http get request using Vue js. I can't seem to find any issues with the logic, although I'm not very experienced with vuejs.

Continuously encountering these two errors:

[Vue warn]: Error in mounted hook: "TypeError: Cannot read property 'get' of undefined"

and

TypeError: Cannot read property 'get' of undefined.

var owm = new Vue({
  el: '#owm',
  data: {
    debug: true,
    weather: []
  },
  methods: {
    loadWeather: function() {
      this.$http.get('http://api.openweathermap.org/data/2.5/find?q=stockholm&type=like&appid=766b78c39446a8fa6313c3b7b2063ade', function(data, status, request){
        if(status == 200)
        {
          this.weather = data;
          console.log(this.weather);
        }
      });
    }
  },
  mounted: function () {
    this.loadWeather();
  }
});

After updating the code using vue resource, the errors have disappeared but the data is not being logged in the console, what could be the issue?

Vue.use(VueResource);
var owm = new Vue({
  el: '#owm',
  data: {
    weather: []
  },
  methods: {
    loadWeather: function() {
      this.$http.get('http://api.openweathermap.org/data/2.5/find?q=stockholm&type=like&appid=[API KEY]', function(data, status, request){
        if(status == 200)
        {
          this.weather = data;
          console.log(this.weather);
        }
      });
    }
  },
  mounted: function () {
    this.loadWeather();
  }
});

UPDATE: This revised code functions as expected, although I'm unsure about the .then function and why it worked with it instead of the callback function.

this.$http.get('http://api.openweathermap.org/data/2.5/find?q=stockholm&type=like&appid=[API KEY]').then((data) => {
  this.weather = data;
  console.log(this.weather);

Answer №1

After experimenting with a sample on my local machine, I discovered that the $http usage was incorrect. The correct way to handle it is by referring to the documentation and using a then function to handle the promise resolution. Here is the updated code snippet that worked for me:

 loadWeather: function() {
    var self=this;
  this.$http.get('http://api.openweathermap.org/data/2.5/find?q=stockholm&type=like&appid=766b78c39446a8fa6313c3b7b2063ade').then(function(response){
    if(response.status == "200"){
        console.log(response);
    self.weather = response.data.list[0].weather // use self instead of this
    }


  })
