Nuxt + axios ...how to add {{this.$route.params}} in axios url? - vue.js

Hello im trying to add {{this.$route.params}} to my axios url for get the data on dedicated profil pages.
here is the part i want to add in axios url the "id" :
The Axios code from 'RikLamers' who explain me how to get data, it is where i want to add "this.$route.params" :
data() {
return {
results: [],
}
},
async mounted() {
await axios.get(`API url" ${to.params.id}`)
.then(response => {this.results = response.data.content})
},
but i mistake somewhere, hope someone can explain me ?

You can access URL param using this.$route.params.id. Use try catch, when you use await.
data() {
return {
results: [],
}
},
async mounted() {
try {
const response = await axios.get(`[Your API URL]/${this.$route.params.id}`)
this.results = response.data.content
catch (e) {}
},

How to access object on Vue front end from axios proxy

I have a locally hosted mongodb database with mongoose, express, axios, and a Vue front end. Right now I'm trying to access a single object from an exported array, but I'm missing the mark and getting "undefined" as the result.
vue.config.js:
module.exports = {
devServer: {
proxy: 'http://localhost:3000',
}
}
here's the front end Vue script meant to use the objects:
import axios from 'axios';
export default {
name: 'Game',
data () {
return {
pages: [],
currentPage: {},
pageTitle: "",
pageText: "",
options: [],
}
},
created () {
this.getPages();
},
methods: {
async getPages() {
try {
let res = await axios.get('/api/pages');
this.pages = res.data;
console.log(this.pages);
this.currentPage = this.pages[0];
console.log(this.currentPage);
return true;
} catch (error) {
console.log(error);
}
},
my "get" endpoint in pages.js:
router.get('/', async (req, res) => {
try {
let pages = await Page.find();
res.send({pages: pages}); //send result of search for pages as list of pages called "pages"
} catch (error) {
console.log(error);
res.sendStatus(500); //500 = server could not fulfill request
}
});
the route in server.js:
const pages = require('./routes/pages');
app.use('/api/pages', pages);
app.listen(3000, () => console.log('Server listening on port 3000!'));
module.exports = app;
and here's the console output, with the "pages" object from vue's data property and the "currentPage" that's supposed to be at pages[0] (printed to console in earlier example):
I can access the api at 'localhost:3000/api/pages' just fine, but how do I break into that array and access the first page object? I want to get an object from the list axios fetches from mongoose, then hold that object in a variable so I can access it's properties. The whole "pages > [[Target]] > pages > [ ]" is part of the problem I'm sure, but I don't know what to tell the code to open it.
Whoops! I realized my mistake. In pages.js I should have sent "res.send(pages);" After a whole couple days too XD

How to use Nuxt Context to call Axios request with param

so I'm trying to get my Axios to do a get request with a param that'll end the url in
'/?user= {id}'
the id is passed in by my loggedInUser.id from Vuex. I know that async functions won't accept 'this' inside the call so I included store as a parameter. Something's still off with how I passed the data around thought I think. Would appreciate any help, thanks!
import { mapGetters } from "vuex";
export default {
computed: {
...mapGetters(["loggedInUser"])
},
head() {
return {
title: "Actors list"
};
},
components: {
EditProfile
},
async asyncData({ store }) {
try {
const body = { data: store.getters.loggedInUser.id };
const { actors } = await $axios.$get(`/api/v1/actors/`, {
params: {
user: body
}
});
return { actors };
} catch (e) {
return { actors: [] };
}
},
data() {
return {
actors: []
};
Edit
I got it to work when I removed the data: from 'const body' and removed the brackets as well around 'actor'
try {
const body = store.getters.loggedInUser.id;
const actors = await $axios.$get(`/api/v1/actors/`, {
params: {
user: body
}
});
You can access your params from Context.
Context is available in special nuxt lifecycle areas like asyncData, fetch, plugins, middleware and nuxtServerInit.
In Nuxt, with asyncData hook you can get query parameters from the route context key.
Please read the Nuxt.js Context documentation. The context provides additional objects/params from Nuxt to Vue components
With your-domain/?user=wonderman
asyncData({ route: { query: queryParams} }) {},
variable queryParams is an object:
{ user: "wonderman" }

Obviously silly mistake trying to pass a value from an Axios response to data object in Vue

I'm sure this is ridiculously simple, but I'm having trouble passing a response from an Axios request to the data object to use elsewhere. It's currently just returning whatever I set as the default in the data object (in this instance, null). Help please! It's greatly appreciated.
My Vue code:
var thing = new Vue({
el: '#el',
data: {
message: null,
},
components: ...
template: ...
methods: {
thing() {
...
}
},
created() {
axios.get('/is-logged')
.then(response => {
if(response.data.status == 'error') {
this.message = response.data.message;
}
})
.catch(e => {
console.log(e);
});
},
mounted() {
if (!this.message) {
console.log(this.message);
this.thing();
}
}
});
The response I get back from is_logged:
{"message":"You are not authorised","status":"error"}
You're logging its value before the AJAX request completes (since the component will be mounted before you get the response from the request in created).
Try putting console.log(this.message) at the end of your then callback.

Axios GET not including params in Nuxt template

I want to pass an id to axios so that I can switch url dynamically.
My axios request in my template is as follows:
async asyncData({ params }) {
const { data } = await axios.get('http://localhost:8000/api/', {
params: {
id: 1
}
})
return { data }
}
The request being passed to my api is:
GET /api/?id=1
but I need
GET /api/1
What is happening here?
It looks like the asyncData function is called once when the page is loaded. I am still no wiser as to why it does not accept params in the way outlined in the docs and numerous tutorials, but it would not refresh the page because it is never called again.
To refresh the page data with a new api call, you need to return the axios promise from within the methods part of the export. The code below does the axios get request first, then adds or subtracts 1 from the id with plus and minus functions.
<script>
import axios from 'axios'
export default {
head() {
return {
title: 'Weather'
}
},
data: function() {
return { counter: 1 }
},
methods: {
plus: function(counter, data, datalength) {
this.counter += 1
axios.get('http://localhost:8000/api/' + this.counter).then(res => {
console.log(this.counter)
console.log(res.data)
return (this.data = res.data)
})
},
minus: function(counter, data) {
if (this.counter >= 2) {
this.counter -= 1
axios.get('http://localhost:8000/api/' + this.counter).then(res => {
console.log(this.counter)
console.log(res.data)
return (this.data = res.data)
})
} else {
this.counter = 1
}
}
},
async asyncData({ params, counter }) {
let { data } = await axios.get('http://localhost:8000/api/1')
return { data }
}
}
</script>
If anybody wants to elaborate or post a better solution, please go ahead - but I'm posting this because I searched so many tutorials and nothing worked until I found a way to interpret the documentation, which is certainly not beginner-friendly.

Unit testing HTTP request with Vue, Axios, and Mocha

I'm really struggling trying to test a request in VueJS using Mocha/Chai-Sinon, with Axios as the request library and having tried a mixture of Moxios and axios-mock-adaptor. The below examples are with the latter.
What I'm trying to do is make a request when the component is created, which is simple enough.
But the tests either complain about the results variable being undefined or an async timout.
Am I doing it right by assigning the variable of the getData() function? Or should Ireturn` the values? Any help would be appreciated.
Component
// Third-party imports
import axios from 'axios'
// Component imports
import VideoCard from './components/VideoCard'
export default {
name: 'app',
components: {
VideoCard
},
data () {
return {
API: '/static/data.json',
results: null
}
},
created () {
this.getData()
},
methods: {
getData: function () {
// I've even tried return instead of assigning to a variable
this.results = axios.get(this.API)
.then(function (response) {
console.log('then()')
return response.data.data
})
.catch(function (error) {
console.log(error)
return error
})
}
}
}
Test
import Vue from 'vue'
import App from 'src/App'
import axios from 'axios'
import MockAdapter from 'axios-mock-adapter'
let mock = new MockAdapter(axios)
describe('try and load some data from somewhere', () => {
it('should update the results variable with results', (done) => {
console.log('test top')
mock.onGet('/static/data.json').reply(200, {
data: {
data: [
{ id: 1, name: 'Mexican keyboard cat' },
{ id: 2, name: 'Will it blend?' }
]
}
})
const VM = new Vue(App).$mount
setTimeout(() => {
expect(VM.results).to.be.null
done()
}, 1000)
})
})
I am not sure about moxios mock adaptor, but I had a similar struggle. I ended up using axios, and moxios, with the vue-webpack template. My goal was to fake retreiving some blog posts, and assert they were assigned to a this.posts variable.
Your getData() method should return the axios promise like you said you tried - that way, we have some way to tell the test method the promise finished. Otherwise it will just keep going.
Then inside the success callback of getData(), you can assign your data. So it will look like
return axios.get('url').then((response) {
this.results = response
})
Now in your test something like
it('returns the api call', (done) => {
const vm = Vue.extend(VideoCard)
const videoCard = new vm()
videoCard.getData().then(() => {
// expect, assert, whatever
}).then(done, done)
)}
note the use of done(). That is just a guide, you will have to modify it depending on what you are doing exactly. Let me know if you need some more details. I recommend using moxios to mock axios calls.
Here is a good article about testing api calls that helped me.
https://wietse.loves.engineering/testing-promises-with-mocha-90df8b7d2e35#.yzcfju3qv
So massive kudos to xenetics post above, who helped in pointing me in the right direction.
In short, I was trying to access the data incorrectly, when I should have been using the $data property
I also dropped axios-mock-adaptor and went back to using moxios.
I did indeed have to return the promise in my component, like so;
getData: function () {
let self = this
return axios.get(this.API)
.then(function (response) {
self.results = response.data.data
})
.catch(function (error) {
self.results = error
})
}
(Using let self = this got around the axios scope "problem")
Then to test this, all I had to do was stub the request (after doing the moxios.install() and moxios.uninstall for the beforeEach() and afterEach() respectively.
it('should make the request and update the results variable', (done) => {
moxios.stubRequest('./static/data.json', {
status: 200,
responseText: {
data: [
{ id: 1, name: 'Mexican keyboard cat' },
{ id: 2, name: 'Will it blend?' }
]
}
})
const VM = new Vue(App)
expect(VM.$data.results).to.be.null
VM.getData().then(() => {
expect(VM.$data.results).to.be.an('array')
expect(VM.$data.results).to.have.length(2)
}).then(done, done)
})
