I'm working on an backend API but at some point I need to get user data from another API. I am trying to use Axios to make http request in order to do that. The request return the result in the browser as expected but the problem is that I can't display console log in the terminal. It doesn't show anything even though I asked the program to do so. Is there a problem probably with my code?
Here is my code :
const axios = require('axios');
const AxiosLogger = require('axios-logger');
const instance = axios.create();
module.exports = (router) => {
router.get('/profile', function(req, res) {
//random fake profile info
axios.get('https://randomuser.me/api/')
.then(response => {
console.log(response.data);
console.log(response.data);
return response.data
})
.catch(error => {
console.log(error);
});
});
};
I would suggest trying response.send to forward the axios response to your client like so:
module.exports = (router) => {
router.get('/profile', function(req, res) {
//random fake profile info
axios.get('https://randomuser.me/api/')
.then(response => {
console.log(response.data);
// Send the axios response to the client...
res.send(response.data)
})
.catch(error => {
console.log(error);
});
});
};

I'm trying to make a post request to the server,but it returns 400 error.
:
this is react function
const handleSubmit = () => {
const bookInstanceObject = {
imprint: imprint,
};
axios
.post('http://localhost:3001/catalog/bookinstance/create', bookInstanceObject)
.then(res => {
console.log(res.data);
})
.catch(error => {
console.log(error);
});
};
and this is the server side:
router.post('/bookinstance/create', (request, response, next) => {
const body = request.body;
const bookInstance = new BookInstance({
imprint: body.title,
});
bookInstance
.save()
.then(savedBook => {
response.json(savedBook.toJSON());
})
.catch(error => next(error));
});
any idea ?
What I think is happening
The front end's handleSubmit function is POSTing to /catalog/bookinstance/create, while the server is expecting it to come to /bookinstance/create.
Simple typo, easy to miss when your stressing over it not working.
How to fix?
Change the URLs to match.
Either:
change the front-end's POST url to /bookinstance/create,
or:
change the server's expected route to router.post('/catalog/bookinstance/create',
Why is it a GET in the error log?
I don't know but I suspect that this error is about a GET request somewhere else in your code.
Please let us know in the comments if the error goes away with this fix. (Assuming my fix works)
When i'm going to localhost:3000/api/categories i'm getting an empty array, but when i log my products there is alot of data inside the object. Anyone knows what i'm doing wrong? Thanks!
let products = getData()
function getData() {
return fetch('some url',
{
method: 'GET',
headers: {
'Content-Type': 'application/json'
}
}
).then(res => res.json())
};
app.get(('/api/categories'), (req, res) => {
products.then(console.log);
res.send(products);
products.then(console.log);
});
products is a promise. You can't send it to the client via res.send.
Instead, do what you're doing when you log it: use then:
app.get(('/api/categories'), (req, res) => {
products
.then(data => res.send(data))
.catch(error => {
// Send an error
});
});
Note that your code gets the products once, at startup, and then responds to the request with that static set of products.
If you want to get the products in response to the request from the client, remove the
let products = getData();
and put it in the get handler:
app.get(('/api/categories'), (req, res) => {
this.getData()
.then(data => res.send(data))
.catch(error => {
// Send an error
});
});
That repeats the request each time the client calls your server.
Of course, you might consider a middle ground, keeping and reusing the data for X seconds...
I'm trying to make a POST request using axios to my firebase cloud-function on form submit in react app. But I get '500' error everytime I make a request with an html-page response This app works best with javascriot enabled.
Latest Update:
It looks like there is no issue with cloud function
code. Rather more of a react-component issue. I used Postman to send
the POST request with header prop Content-Type set to application/json
and sending body in raw format {"email": "example_email"} and got
expected response from the cloud function. But when sent the request from
react component above, I get an html file response saying the app
works best with javascript enabled
I've tried setting Content-Type to both Application/json and multipart/form-data as I suspected it to be an issue but still got no luck.
Following is my code for cloud function and react submit form:
Cloud Function
const functions = require('firebase-functions');
const cors = require('cors')({ origin: true })
const runThisFunc1 = require(./libs/runThisFunc1);
const runThisFunc2 = require(./libs/runThisFunc2);
exports.wizardFunc = functions.https.onRequest((request, response) => {
cors(request, response, () => {
let email = request.body.email;
try {
return runThisFunc1(email)
.then(data => {
console.log("Word Done by 1!");
return runThisFunc2(data);
})
.then(res => {
console.log("Word Done by 2!");
return response.status(200).send("Success");
})
.catch(err => {
console.error("Error: ", err.code);
return response.status(500).end();
});
}catch(err) {
return response.status(400).end();
}
});
});

Is there something wrong I am doing in the code or the request config is wrong?
I'm currently developing a 'Dupe Finder' web app for a co-worker. This is my first time using the 'csvtojson' package.
I'm reading from the file just fine on the server, but when I send a response back to the client (ideally containing a json object) I'm getting this very odd console log and I'm not sure if its correct:
To get this response, I have a button on the home page, when clicked, the client makes an http request on the home directory of the server, called '/getnums'. The request reads from the CSV then should be returning and obj with its contents. It is sort of doing that, in the screenshot, if I click the tick next to promiseValue, it'll give me an array. But i'm not sure why its returning a Promise..anyway..
api.js:
var CSVDATA = () => {
fetch('/getnums')
.then(res => {
console.log(res.json())
})
}
export default {
CSVDATA,
}
'/getnums' goes to my router, which is simly router.get('/', mainController.getNums)
in the controller is where the reading begins:
const csv = require('csvtojson')
module.exports = {
getNums: (req, res, next) => {
const csvFilePath = `${__dirname}/../../client/readFrom/main.csv`
csv().fromFile(csvFilePath)
.then(jsonObj => {
return res.status(200).json(jsonObj)
})
.catch(e => {
req.error = e
next()
})
},
}
anyone have an idea what might be going on here?
That is simply how .json() works.
It returns promise so you need to handle it asynchronously
var CSVDATA = () => {
fetch('/getnums')
.then(res => res.json())
.then(json => console.log(json));
}
export default {
CSVDATA,
}

API requests are failing because the URL generated by Axios is incorrect due to my config. I know what the request url is suppose to look like, so I want to see the request url Axios generates.
I can point Axios to my local server and see the requests there, but I want to debug this on the client. I want to play with the config, and see how the requests change. Is there a way to output the request url from Axios before or after sending?
// param format
{ address: 'Vancouver', key: GOOGLE_API_KEY }
// Geocode sample
https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY
_request = async (...args) => {
const { outputFormat, params } = args
const instance = axios.create({
baseURL: `https://maps.googleapis.com`,
})
const response = await instance.get('/maps/api/geocode/${outputFormat}?', {
params,
})
// I want to see the url generated by Axios so I can debug the issue
console.log(response)
}
I am within the Expo, React Native environment.
Working example using fetch:
const url = `https://maps.googleapis.com/maps/api/geocode/json?address=vancouver&key=${GOOGLE_API_KEY}`
fetch(url)
.then((response) => response.json())
.then((data) => {
console.log(data)
})
.catch(function(error) {
console.log(error)
})
Solution used:
_request = async (obj) => {
const { outputFormat, params } = obj
const instance = axios.create({
baseURL: `https://maps.googleapis.com`,
})
instance.interceptors.request.use(function (config) {
console.log(config)
return config
}, function (error) {
return Promise.reject(error)
})
const response = await instance.get(`/maps/api/geocode/${outputFormat}`, {
params,
})
}
You can turn on debug mode and look at the network tab as mentioned in the other answer, or you can intercept axios and console.log or do whatever you want with the request before it's sent:
axios.interceptors.request.use(function (config) {
// Do something before request is sent
console.log(config)
return config;
}, function (error) {
// Do something with request error
return Promise.reject(error);
});
You can just use axios#getUri([config]) (source) to perform the same logic as the request. It merges the configurations (e.g. the given config and the instance configuration), merges the url with the baseURL, and appends any params using the paramSerializer.
