Hy, I try to get some data from a nodeJs API. I use react for frontend. I make my node API, I test with Postman and it work fine. When I use axios for get my data from the server I get a cors Error.
This is my axios call from react:
async function getMagazin(){
return (await axios.get(URL)).data;
}
And this is my node Js API:
import express from 'express';
import bodyParser from 'body-parser';
import db from './dbConfig.js';
import Magazin from './entities/Magazin.js';
import cors from 'cors';
let app = express();
let router = express.Router();
app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());
app.use('/api', router);
app.use(cors());
app.use(function(req, res, next) {
res.setHeader("Access-Control-Allow-Origin", "*");
res.setHeader('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
if ('OPTIONS' == req.method) {
res.sendStatus(200);
}
else {
next();
}});
async function getMagazin(){
return await Magazin.findAll();
}
router.route('/magazin').get(async (req, res) => {
res.json(await getMagazin());
})
let port = process.env.PORT || 8000;
app.listen(port);
console.log("API is running at " + port);
I try to add cors in my node API and hope the error is gone but not.
This is the error:
I try to make I debug, the api call go on the server and execute sql query, but when he return he give me that error. What I must add in my server side code for the API to work?
