It's Vue.js app and the code looks as following:
getQrCodeUrl(paymentId) {
this.$axios.get(`${this.$config.server}/api/crm/payments/qr/${paymentId}/url`)
.then(responseUrl => {
console.log('responseUrl.data =', responseUrl.data)
console.log('responseUrl.data.url =', responseUrl.data.url)
})
.catch(error => {
...
})
},
I've got responseUrl.data, but responseUrl.data.url is undefined as in the screenshot below:
The screenshot shows you that responseUrl is an object with result and data properties. I believe it is the successful promise. By adding a .then(response => response.json()), you will have the data by itself as a JSON object.
Refactor the code as follows :-
getQrCodeUrl(paymentId) {
this.$axios.get(`${this.$config.server}/api/crm/payments/qr/${paymentId}/url`)
.then(response => response.json())
.then(response => {
console.log('response.url =', response.url)
})
.catch(error => {
...
})
},

i already call the axios and show using console log if it is successful or not already, However i wanted to pass the axios post response value to my vue component and display the response in my vue component in order for me to make a condition. Is there any way to do it? I try some other part but no luck. Kindly guide me.
main.vue
methods: {
onClicked() {
this.$store
.dispatch('Clickme', this.data)
.then(() => {
alert("Success");
})
.catch(() => {
alert("Error");
})
}
}
clicked.js
return new Promise((resolve, reject) => {
clicked(username, password)
.then(resp => {
console.log("---->>>> : ");
const data = resp.data.data
console.log(username, password);
console.log(resp);
console.log("statresponse.status : " + resp.data.status);
console.log("statresponse.message : " + resp.data.message);
console.log("statresponse.inside message : " + resp.data.data.message);
// console.log("USER.JS RESPONSE: " + resp.data.status);
// console.log("USER.JS RESPONSE: " + resp.data.message);
setToken(data.token)
commit('SET_TOKEN', data.token)
resolve()
})
.catch(error => {
console.log(error)
reject(error)
})
})
Try changing main.vue to:
onClicked() {
this.$store
.dispatch('Clickme', this.data)
.then((response) => {
//Do whatever you want with your response
alert("Success");
})
.catch(() => {
alert("Error");
})
}
and change clicked.js to:
resolve(resp.data.data)
This will make so the promise resolves the response data.
However if you make the http request in your store/using vuex, what you probably want to do is commit a mutation to put the response into your state - and then map the state from your component.
If I call my api function from POINT 1, fetch method inside the api method works well. When I comment it out and call the function at POINT 2 fetch method inside the addAccount() doesn't work. There is no exception, no rejection, no request on Reactotron, even I can't find request over Charles Proxy. What is the difference and what I have to know to figure it out?
I tried with RN 0.55.2 and 0.57.5
// Auth.js typical react native component
import * as api from '../actions/api';
class Auth extends Component {
// first triggered function
loginAccount(){
// api.addAccount(); // POINT 1 - this line works well if I uncomment
fetch('https://domain-a.com/login/',{
method: 'POST',
credentials: "same-origin",
headers: {
'accept-language': 'en-US;q=1',
'Content-type': 'application/x-www-form-urlencoded; charset=UTF-8',
},
body: encodeURIComponent(bodyParameters)
}).then((response) => {
console.log(response);
return response.json()
}).then(({ status, invalid_credentials }) => {
if(status == "ok"){
CookieManager.get('https://domain-a.com')
.then((cookies) => {
this.fetchAccountData(cookies);
})
})
}
fetchAccountData(cookies){
fetch('https://domain-a.com/'+cookies.user_id+'/info/',{
method: 'GET',
headers: {
'cookie': cookies
}
}).then((response) => {
return response.json();
})
.then(({ user, status }) => {
api.addAccount(); // POINT 2 - this line doesn't work
});
}
}
// api.js
// I repleaced fetch code with document example just to be clearify
export const addAccount = () => {
console.log("fetch begin"); // always works
fetch('https://facebook.github.io/react-native/movies.json')
.then((response) => response.json())
.then((responseJson) => {
console.log(responseJson); // won't works from point 2
})
.catch((error) =>{
console.error(error); // never runs
});
}
It looks like your first .then statement in the addAccount() function is missing a return statement. responseJson would be undefined without a proper a 'return response.json()' statement. Also adding brackets for better semantic formatting.
export const addAccount = () => {
console.log("fetch begin"); // always works
fetch('https://facebook.github.io/react-native/movies.json')
.then((response) => {
console.log(response); //test this response
return response.json();
})
.then((responseJson) => {
console.log(responseJson); // won't works from point 2
})
.catch((error) =>{
console.error(error); // never runs
});
}
I'm trying to find the correct way to get the number of returned results from my async axios get query but not getting anywhere so hoping someone can assist
My code is as follows
mounted() {
axios.get('http')
.then(response => {
this.myItems = response.data // this works
countResults(response) //this doesn't seem to
.catch(error => console.log(error))
})
},
filters:{
countResults: function(value){
return value.length;
}
I then call as follows
<p>Number of Entries: {{countResults}}</p>
Thanks
You can call the filter method in this way
this.$options.filters.countResults(response)
To solve your problem you need to store the response. You can do that in this way
mounted() {
axios.get('http')
.then(response => {
this.myItems = response.data // this works
this.responseData = response.data
}).catch(error => console.log(error))
},
data: {
responseData: []
},
filters: {
countResults: function(){
return this.responseData.length;
}
Im trying to call an API with fetch from React Native App but itdoesnt log the response data (console.warn('data', data)) for some reason. It prints the 'call to getArtists' log but then nothing happens.
const URL = 'https://jsonplaceholder.typicode.com/posts'
function getArtists(){
console.log('call to getArtists')
return fetch(URL)
.then(response => response.json())
.then(data => {
console.warn('data', data)
})
}
Code is available here: https://snack.expo.io/rkzea2Zlm at components/api-client.js
What am I doing wrong?
First in your "api_client.js", put a return inside like the code bellow.
function getArtists(){
console.log('call to getArtists')
return fetch(URL)
.then(response => response.json())
.then(data => {
return data
})
}
In your App.js just do that inside componentWillMount.
componentDidMount(){
getArtists()
.then(data => {
alert(JSON.stringify(data))
});
}
I'm trying out ES2015 modules in Chrome Canary Version 60.0.3102.0. My script.js file reads like this:
import {fetchJSON} from './functions/fetchJSON.js';
const configFile = 'config.json';
const init = () => {
fetchJSON(configFile)
.then((data) => { // code fails here at ln.7
console.log(data);
})
.catch(error => console.log(error));
};
init();
and my fetchJSON.js file reads like this:
export function fetchJSON(url) {
const fetchJSON = fetch(url)
.then(response => response.json())
.then(data => {
console.log(data); // data exists and is reported in the console
return data;
});
}
I'm getting the error:
script.js:7 Uncaught TypeError: Cannot read property 'then' of undefined
at init (script.js:7)
at script.js:14
Your fetchJSON function isn't returning anything. Because of that, when you try chaining a .then on the result of fetchJSON, you're getting the Uncaught TypeError - undefined.
Solution: return your Promise chain in your fetchJSON function:
export function fetchJSON(url) {
return fetch(url)
.then(response => response.json())
.then(data => {
return data;
});
}
