I am trying to get data from a 3rd-party API, but cannot get any data back from it in my program. However, I can get it to work via Postman.
params in Postman:
JSON from Postman:
JSON from console:
the code in question:
const consola = require('consola');
const express = require('express');
const axios = require('axios');
const app = express();
// GET - /api/title
app.get('/', (req, res) => {
const title = 'and then there were none'; // this is just until data is coming from user input
const replaceSpaces = (str) => str.split(' ').join('+');
axios
.get('https://tastedive.com/api/similar', {
params: {
q: replaceSpaces(title),
type: 'books',
info: 1,
limit: 7,
k: process.env.TASTE_DIVE_KEY,
},
})
.then(({ data }) => {
consola.ready({
message: `data from axios server ${JSON.stringify(data)}`,
badge: true,
});
res.json(data);
})
.catch((error) => {
res.status(400).json(error);
consola.error({
message: `error from axios server ${error}`,
badge: true,
});
});
});
Does anybody know what could be causing this discrepancy? I have the same params in both my code and in Postman, but I'm not getting the full data back in my app that I am in Postman.

I tried to deploy my local running MERN stack project to Heroku. The UI is showing fine, but the axios calls continue to fail. Here is how I wrote the axios URL.
axiosConfig.js:
import axios from "axios";
const api = axios.create({
baseURL: process.env.REACT_APP_BASE_URL // or process.env.BASE_URL if not using CRA
});
export default api
Arrival.js:
import api from '../../axiosConfig';
const Arrivals = () => {
const baseURL = api || "http://localhost:5000";
useEffect(() => {
axios.get(baseURL + '/flights/arrivals/' + timeDuration)
.then((response) => {
setData(response.data);
console.log(data)
})
.catch(err => {
console.log(err)
})
}, [timeDuration]);//eslint-disable-line
When I call the api, the network showing it's tring to get from:
https://minions-airport-202.herokuapp.com/function()%7Breturn%20e.apply(t,arguments)%7D/flights/arrivals/28800000
And it is getting 500 Internal Server Error. Any idea why?
I am in a next-js app and my auth token is stored in cookies.
For some raisons i use Swr and Api route to fetch my secured api backend.
i am trying to find a way to put my auth token in all api request.
During login cookie is set
res.setHeader(
'Set-Cookie',
cookie.serialize('token', data.access_token, {
httpOnly: true,
secure: process.env.NODE_ENV !== 'development',
maxAge: data.expires_in, // 1 week
sameSite: 'strict',
path: '/',
}),
);
This is an example of a page using swr fetch
//page/test.ts - example of my test route
const { data, error } = useFetchContent(id);
if (error) {
showError('error');
replace('/');
}
return <DisplayContent content={data} />
This is a swrFetchHook
// fetchContentHook
function useFetchContent(id: string): ContentDetail {
return useSWR<any>(`/api/content/${id}`, fetcherApiRoute);
}
const fetcherApiRoute = (url: string): Promise<any> => {
return axios(url)
.then((r) => r.data)
.catch((err) => {
console.info('error is ', err)
throw err
});
};
export default useFetchContent;
inside api route
export default async (req, res): Promise<ContentDetail> => {
const { id } = req.query;
if (req.method === 'GET') {
const fetchRealApi = await apiAxios(url);
if(fetchRealApi) {
// here depending on result of fetchRealApi i add some other fetch ...
return res.status(200).json({ ...fetchRealApi, complement: comp1 });
}
return res.status(500)
}
return res.status(500).json({ message: 'Unsupported method only GET is allowed' });
};
and finally api axios configuration
const apiAxios = axios.create({
baseURL: '/myBase',
});
apiAxios.interceptors.request.use(
async (req) => {
// HERE i am trying to get token from cookies
// and also HERE if token is expired i am trying to refresh token
config.headers.Authorization = token;
req.headers['Content-type'] = 'application/x-www-form-urlencoded';
return req;
},
(error) => {
return Promise.reject(error);
},
);
export default apiAxios;
I am stuck here because i cant find token during apiAxios.interceptors.request.use...
Did you know what i am doing wrong, and am i on a correct way to handle this behavior ?
To allow sending server cookie to every subsequent request, you need to set withCredentials to true. here is the code.
const apiAxios = axios.create({
baseURL: '/myBase',
withCredentials: true,
});
Nilesh's answer is right if your API is able to authorize requests based on cookies. Also it needs the API to be in the same domain as your frontend app. If you need to send tokens to the API (the one which is in the cookie), then you will need a small backend component often called BFF or Token Handler. It can extract the token from the cookie and put in an Authorization header.
At Curity we've created a sample implementation of such a Token Handler, of which you can inspire: https://github.com/curityio/kong-bff-plugin/ You can also have a look at an overview article of the Token Handler pattern.
I'm using contact forms 7, and in my form submission I use this function:
const formData = {
'your-name':'John Doe',
'your-email': 'johndoe#mail.com',
}
axios({
method: 'POST',
url: 'https://0xsociety.com/wp-json/contact-form-7/v1/contact-forms/258/feedback',
headers: {
"content-type": "multipart/form-data",
},
data: formData,
})
But it doesnt work, i get errors saying fields are empty.
But I tried with postman and it works perfectly when i do it manually
How would I get my axios post request to mimic this:
https://gyazo.com/e1ffe5bcc3f943a074d9b9e2c32b162d
I figured this out by using postman in my app:
import request from 'postman-request'
const formData = {
'your-name': name,
'your-email': email,
'your-subject': inquiries.find(x=> x.value === inquiry).text,
'file-871': file
}
request.post('https://your-domain/wp-json/contact-form-7/v1/contact-forms/your-form-id/feedback',{ form: formData}, function(err,httpResponse,body){
if(err) {
console.log(err)
}
else {
console.log(body)
}
})
Forgive me if it's a silly question, but the last time I coded in javascript was almost 20 years ago... I'm re-learning javascript these weeks and I'm not sure I got it all.
I'm using hapi with rest-hapi and want to add some standalone endpoints, basically translating the backend portion of this Autodesk tutorial form express.
I'm using the basic rest-hapi example main script, and tried to add a route with the following code:
//api/forge.js
module.exports = function(server, mongoose, logger) {
const Axios = require('axios')
const querystring = require('querystring')
const Boom = require('boom')
const FORGE_CLIENT_ID = process.env.FORGE_CLIENT_ID
const FORGE_CLIENT_SECRET = process.env.FORGE_CLIENT_SECRET
const AUTH_URL = 'https://developer.api.autodesk.com/authentication/v1/authenticate'
const oauthPublicHandler = async(request, h) => {
const Log = logger.bind('User Token')
try {
const response = await Axios({
method: 'POST',
url: AUTH_URL,
headers: {
'content-type': 'application/x-www-form-urlencoded',
},
data: querystring.stringify({
client_id: FORGE_CLIENT_ID,
client_secret: FORGE_CLIENT_SECRET,
grant_type: 'client_credentials',
scope: 'viewables:read'
})
})
Log.note('Forge access token retrieved: ' + response.data.access_token)
return h.response(response.data).code(200)
} catch(err) {
if (!err.isBoom){
Log.error(err)
throw Boom.badImplementation(err)
} else {
throw err
}
}
}
server.route({
method: 'GET',
path: '/api/forge/oauth/public',
options: {
handler: oauthPublicHandler,
tags: [ 'api' ],
plugins: {
'hapi-swagger': {}
}
}
})
}
The code works and I can display the access_token in nodejs console, but swagger doesn't get the response:
At first I thought that an async function cannot be used as handler, but my hapi version is 17.4.0, and it supports async handlers.
What am I doing wrong?
It turns out it was an easy fix: I just needed to specify the Hapi server hostname in my main script!
The problem was with CORS, since Hapi used my machine name instead of localhost. Using
let server = Hapi.Server({
port: 8080,
host: 'localhost'
})
solved my problem.
I am building a content management system for an art portfolio app, with React. The client will POST to the API which uses Mongoose to insert into a MongoDB. The API then queries the DB for the newly inserted image, and returns it to the client.
Here's my code to connect to MongoDB using Mongoose:
mongoose.connect('mongodb://localhost/test').then(() =>
console.log('connected to db')).catch(err => console.log(err))
mongoose.Promise = global.Promise
const db = mongoose.connection
db.on('error', console.error.bind(console, 'MongoDB connection error:'))
const Schema = mongoose.Schema;
const ImgSchema = new Schema({
img: { data: Buffer, contentType: String }
})
const Img = mongoose.model('Img', ImgSchema)
I am using multer and fs to handle the image file. My POST endpoint looks like this:
router.post('/', upload.single('image'), (req, res) => {
if (!req.file) {
res.send('no file')
} else {
const imgItem = new Img()
imgItem.img.data = fs.readFileSync(req.file.path)
imgItem.contentType = 'image/png'
imgItem
.save()
.then(data =>
Img.findById(data, (err, findImg) => {
console.log(findImg.img)
fs.writeFileSync('api/uploads/image.png', findImg.img.data)
res.sendFile(__dirname + '/uploads/image.png')
}))
}
})
I can see in the file structure that writeFileSync is writing the image to the disk. res.sendFile grabs it and sends it down to the client.
Client side code looks like this:
handleSubmit = e => {
e.preventDefault()
const img = new FormData()
img.append('image', this.state.file, this.state.file.name)
axios
.post('http://localhost:8000/api/gallery', img, {
onUploadProgress: progressEvent => {
console.log(progressEvent.loaded / progressEvent.total)
}
})
.then(res => {
console.log('responsed')
console.log(res)
const returnedFile = new File([res.data], 'image.png', { type: 'image/png' })
const reader = new FileReader()
reader.onloadend = () => {
this.setState({ returnedFile, returned: reader.result })
}
reader.readAsDataURL(returnedFile)
})
.catch(err => console.log(err))
}
This does successfully place both the returned file and the img data url on state. However, in my application, the image always displays broken.
Here's some screenshots:
How to fix this?
Avoid sending back base64 encoded images (multiple images + large files + large encoded strings = very slow performance). I'd highly recommend creating a microservice that only handles image uploads and any other image related get/post/put/delete requests. Separate it from your main application.
For example:
I use multer to create an image buffer
Then use sharp or fs to save the image (depending upon file type)
Then I send the filepath to my controller to be saved to my DB
Then, the front-end does a GET request when it tries to access: http://localhost:4000/uploads/timestamp-randomstring-originalname.fileext
In simple terms, my microservice acts like a CDN solely for images.
For example, a user sends a post request to http://localhost:4000/api/avatar/create with some FormData:
It first passes through some Express middlewares:
libs/middlewares.js
...
app.use(cors({credentials: true, origin: "http://localhost:3000" })) // allows receiving of cookies from front-end
app.use(morgan(`tiny`)); // logging framework
app.use(multer({
limits: {
fileSize: 10240000,
files: 1,
fields: 1
},
fileFilter: (req, file, next) => {
if (!/\.(jpe?g|png|gif|bmp)$/i.test(file.originalname)) {
req.err = `That file extension is not accepted!`
next(null, false)
}
next(null, true);
}
}).single(`file`))
app.use(bodyParser.json()); // parses header requests (req.body)
app.use(bodyParser.urlencoded({ limit: `10mb`, extended: true })); // allows objects and arrays to be URL-encoded
...etc
Then, hits the avatars route:
routes/avatars.js
app.post(`/api/avatar/create`, requireAuth, saveImage, create);
It then passes through some user authentication, then goes through my saveImage middleware:
services/saveImage.js
const createRandomString = require('../shared/helpers');
const fs = require("fs");
const sharp = require("sharp");
const randomString = createRandomString();
if (req.err || !req.file) {
return res.status(500).json({ err: req.err || `Unable to locate the requested file to be saved` })
next();
}
const filename = `${Date.now()}-${randomString}-${req.file.originalname}`;
const filepath = `uploads/${filename}`;
const setFilePath = () => { req.file.path = filepath; return next();}
(/\.(gif|bmp)$/i.test(req.file.originalname))
? fs.writeFile(filepath, req.file.buffer, (err) => {
if (err) {
return res.status(500).json({ err: `There was a problem saving the image.`});
next();
}
setFilePath();
})
: sharp(req.file.buffer).resize(256, 256).max().withoutEnlargement().toFile(filepath).then(() => setFilePath())
If the file is saved, it then sends a req.file.path to my create controller. This gets saved to my DB as a file path and as an image path (the avatarFilePath or /uploads/imagefile.ext is saved for removal purposes and the avatarURL or [http://localhost:4000]/uploads/imagefile.ext is saved and used for the front-end GET request):
controllers/avatars.js (I'm using Postgres, but you can substitute for Mongo)
create: async (req, res, done) => {
try {
const avatarurl = `${apiURL}/${req.file.path}`;
await db.result("INSERT INTO avatars(userid, avatarURL, avatarFilePath) VALUES ($1, $2, $3)", [req.session.id, avatarurl, req.file.path]);
res.status(201).json({ avatarurl });
} catch (err) { return res.status(500).json({ err: err.toString() }); done();
}
Then when the front-end tries to access the uploads folder via <img src={avatarURL} alt="image" /> or <img src="[http://localhost:4000]/uploads/imagefile.ext" alt="image" />, it gets served up by the microservice:
libs/server.js
const express = require("express");
const path = app.get("path");
const PORT = 4000;
//============================================================//
// EXPRESS SERVE AVATAR IMAGES
//============================================================//
app.use(`/uploads`, express.static(`uploads`));
//============================================================//
/* CREATE EXPRESS SERVER */
//============================================================//
app.listen(PORT);
What it looks when logging requests:
19:17:54 INSERT INTO avatars(userid, avatarURL, avatarFilePath) VALUES ('08861626-b6d0-11e8-9047-672b670fe126', 'http://localhost:4000/uploads/1536891474536-k9c7OdimjEWYXbjTIs9J4S3lh2ldrzV8-android.png', 'uploads/1536891474536-k9c7OdimjEWYXbjTIs9J4S3lh2ldrzV8-android.png')
