Hi so I have been using this node server for some time and it recently stopped working (presumably due to some logical error I mistakenly adjusted), throwing a 404 when I run the server. When I call on it with an http request it throws a 404 as well and shows the same on load from the actual URL in a browser. What is going on?

Other details:
Two important files: index.js & api.js but functionality is all in api.js which is why URL stem goes: .../api/...
Ok got the issue and its as silly as it can get. Are you sure you started the right server ? Its definitely not the node server. Its the http-server you have started. To start the server through node you need to go into the directory (in the terminal) and write "node index.js". Necessary code to start a http-server is written inside index.js.
Got this from the below screenshot.
the error for me is that you are making a GET request on a route that requires a POST request:
router.post('/new_charge', function (req, res) {
...
})
So you should check that you are making a post request to this route and not a GET request. How are you accessing that route from the client?
There is no router.get route for '/api/new_charge', there is one router.post route though.
Where is your router.get('/new_charge') route? it's not in the files you posted. You might have either deleted it or the /new_charge route needs to be used as post and not get.

I have a mongo model like this:-
var mongoose = require('mongoose');
const itemsModel = new mongoose.Schema({
_id: {
type: String,

userName: {
type: String,

});
module.exports = mongoose.model("itemsModel", itemsModel);
and I am handling my backend route in a file called itemRoute.js like this:-
const express = require("express");
const router = express.Router();
const id = require('uuid');
const itemsModel = require("../src/model/itemsModel");
router.post('/add-item/', (req, res) => {
const { userName, description, itemId } = req.body;
itemsModel.findOne({
itemId: itemId,
userName: userName,
}, (error, prevData) => {
if(error){
return res.send({
success: false,
description: `Internal Server Error ${error}`
});
}
if (prevData.length > 0){
itemsModel.findOneAndUpdate(
{ _id: prevData[0]._id },
{ description: description },
(error, status) => {
if (error){
return res.json({

} else {
return res.status(200).json({

);
}
const newModel = new itemsModel;

I have the following in my index.js express file:-
app.use('/api', require('./routes/itemRoute'));
and I am calling from my frontend like this:-
handleAddItemButton = (event) => {
event.preventDefault();
const data = {
userName: this.props.userName,
description: this.state.description,
itemId: this.props.itemId,
}
fetch(`http://localhost:8000/api/add-item/`, {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify(data)
})
.then(res => res.json())
.then(res => {
console.log(res);
})
.catch((err) => console.log(err));
};
My index.js file:-
/* jshint esversion:6 */
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const path = require('path');
const mongoose = require('mongoose');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({

}));
app.use(express.static('./build'));
app.use(express.static('./build/static'));

})
app.get('/*', (req, res) => {
res.sendFile(path.resolve('./build/index.html'))
})
app.listen(port, () => console.log(`server running at ${port}`));
When my frontend actually makes the request, I am thrown the following error:-
POST http://localhost:8000/api/add-item/ net::ERR_CONNECTION_REFUSED
I have looked through my code again and again but to no avail. Any and all help is sincerely appreciated. Please guide me through what Im doing wrong.
Edit 1:-
After #ewokx comment I ran mongod and got the following;-
Is this the issue? How to solve this?
MongoDB requires a data folder to store its files.
The default location for the MongoDB data directory is c:\data\db. So, create this folder it will solve your issue.
Hi so I seem to have successfully solved the problem. The problem wasn't with any of the things like db permissions, mongod, ports or something like that. I reset my index.js file to match the db name in the db connection.
Another thing I was doing wrong, I was passing a json stringified object as the request body. Removing that and on connecting proeprly to the db, the code started working nicely.
I'm trying to follow the Stripe Checkout subscription instructions:
https://stripe.com/docs/billing/subscriptions/build-subscriptions?ui=checkout
When I submit the form, over localhost I get "Cannot POST /create-checkout-session" (404 in network tab), and if I run from my production server, it just opens /create-checkout-session as a new (blank) Vue page. I have tried changing the form action to https://mydomain.xyz/create-checkout-session, but it didn't work.

I'm currently learning angular and working on a project with a mongoDB database and express for my APIs. I want to fetch the comments of a post by the post ID,
The get request returns me a list of comments. the problem is when I first run node js the get request doesn't work, it only works when I first post a new comment and then run the get request for the comments again.
And as long as node is running the get request will continue to work whenever it's called for, until I restart node once again for the error to happen again.
it returns a 404 not found error.
This error doesn't happen with any other route, but my code is the same in all of them.
PS : I Have made sure that the function is getting the post id before the get request is made.

Well, that's very obvious that the server can't find the entity in the DB.
You need to check one of the following:
Maybe when you restart the node server, you restart the db too. that can happen if you're using docker-compose locally. then when you run your node server again your DB starts but there's no data in the DB, therefore the service can't find any data.
After service restart you're using non-existing ID because of wrong UI flow.
I would guess that you're facing the first option.
I have an express API and a ReactJs front-end. I try to make a POST call from my front-end directly to the local API.
For this I'm using axios.
The request is working fine when I set the parameters directly inside the query string but is always getting on timeout if I try to add the parameters through the data attribute of the axios.post() method.
Working
axios.post(`http://localhost:5001/site/authenticate?username=demo&password=demo`)
Not working
const payload = {
"username":"mh",
"password":"mh"
}
axios.post(`http://localhost:5001/site/authenticate`, payload)
My express server:
const express = require('express');
const bodyParser = require('body-parser');
const morgan = require('morgan');
const jwt = require('jsonwebtoken'); // used to create, sign, and verify tokens
var cors = require('cors');
const app = express();
const port = process.env.API_PORT || 5001;
app.use(cors());
app.set('secret', process.env.API_SECRET);
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.use(morgan('dev'));
app.use((req, res, next) => {
let data = '';
req.setEncoding('utf8');
req.on('data', (chunk) => {
data += chunk;
});
req.on('end', () => {
req.rawBody = data;
next();
});
});
// Allow CORS
app.use(function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next();
});
// SITE ROUTES -------------------
const siteRoutes = express.Router();
siteRoutes.post('/authenticate', function(req, res) {
console.log('auth');
getDocument(usersBucket, req.query.username)
.then((doc) => {
console.log("Authentification... TODO");
// return the information including token as JSON
res.json({
success: true,
status: 200,
token: token
});
})
.catch(() => {
res.status(401).json({ success: false, message: 'Authentification failed. User not found.' });
});
});
// route middleware to verify a token
siteRoutes.use(function(req, res, next) {
const token = req.body.token || req.query.token || req.headers['x-access-token'];
if (token) {
// verifies secret and checks exp
jwt.verify(token, app.get('secret'), function(err, decoded) {
if (err) {
return res.json({ success: false, message: 'Failed to authenticate token.', status: 401 });
} else {
req.decoded = decoded;
next();
}
});
} else {
return res.status(403).send({
success: false,
message: 'No token provided.'
});
}
});
siteRoutes.get('/', function(req, res) {
res.json({ message: 'Welcome!' });
});
app.use('/site', siteRoutes);
app.listen(port, () => {
logger.log(`Express server listening on port ${port}`);
});
Any idea? Thanks.
Update
I replaced my route just to see if I got in or not (without worrying about parameters):
siteRoutes.post('/authenticate', function(req, res) {
console.log("go in");
res.json({
success: true,
status: 200,
});
});
But my console.log is not showing hen I use the payload (it is when I do not).
You should access the payload data via request.body, not the request.query:
// SITE ROUTES -------------------
const siteRoutes = express.Router();
siteRoutes.post('/authenticate', function(req, res) {
console.log('auth');
getDocument(usersBucket, req.body.username) // <------- HERE
.then((doc) => {
console.log("Authentification... TODO");
// return the information including token as JSON
res.json({
success: true,
status: 200,
token: token
});
})
.catch(() => {
res.status(401).json({ success: false, message: 'Authentification failed. User not found.' });
});
});
request.query are the parameters passed in the URL, like:
protocol://hostname:port/path/to.route?query_param_0=value_0&query_param_1=value_1
on your express endpoint request.query will be:
{
query_param_0: value_0,
query_param_1: value_1
}
while sending the payload, with the second argument in axios.post(url, payload):
axios.post('/user', {
firstName: 'Fred',
lastName: 'Flintstone'
})
on your express endpoint request.body will be:
{
firstName: 'Fred',
lastName: 'Flintstone'
}
when you use app.use(bodyParser.json()); (and you do).
You are using “getDocument(usersBucket, req.query.username)”
This means you express route is expecting username as a request param. That’s why it’s working when you use “?username=xx”
Instead try to get it from json body of request.
“req.body.username”
Also you should consider validating the request body or param as required.
I'm building my first SPA project with Vue.
I decided to go with NodeJS for the back-end, however, I'm having a headache building the login function with the JsonWebToken.
I had wrote some codes to see how JWT works and when I tried to see how JWT gets verified, server gave me an error.
JsonWebTokenError: jwt must be provided
at Object.module.exports [as verify] (c:\dir\node_modules\jsonwebtoken\verify.js:39:17)
at c:\projects\practice\demo\back\server.js:34:17
Below is the code for my server.js
This is the code for importing the stuff.
const express = require('express');
const jwt = require('jsonwebtoken');
const bodyParser = require('body-parser');
const api = express();
api.use(bodyParser.json());
api.use(bodyParser.urlencoded({ extended: true }));
This is for the API for issuing JWT.
api.post('/secure', function (req, res) {
const token = jwt.sign({ user: {id:1, name:'ME!', role: 'average'} }, 'dsfklgj');
console.log(token);
res.json({jwt: token});
});
This is the API for checking JWT.
api.post('/check/post', function (req, res) {
const token = req.body.jwt;
const x = jwt.verify(token, 'dsfklgj', function (err, decoded) {
if (err) throw err;
console.log(decoded);
});
if (x != true) {
res.json({ auth: false });
}else {
res.json({ auth: true });
}
});
jwt must be provided
This error happens when the coming token is null or empty.
Make sure that the Authorization header has a value of Bearer <Access Token>. Bearer < white space > < Access Token >
It may be you have not defined jwt in specific file or it is null or empty. Therefore you are getting an error. I just test your code and it works for me. It may be that you are not sending jwt token into post request correctly.
const express = require('express');
const jwt = require('jsonwebtoken');
const bodyParser = require('body-parser');
const http = require('http');
const api = express();
api.use(bodyParser.json());
api.use(bodyParser.urlencoded({ extended: true }));
api.post('/secure', function(req, res) {
const token = jwt.sign({ user: { id: 1, name: 'ME!', role: 'average' } }, 'dsfklgj');
console.log(token);
res.json({ jwt: token });
});
api.post('/check/post', function(req, res) {
const token = req.body.jwt;
console.log('token: ' + token);
const x = jwt.verify(token, 'dsfklgj', function(err, decoded) {
if (err) throw err;
console.log(decoded);
});
console.log(x);
if (x != true) {
res.json({ auth: false });
} else {
res.json({ auth: true });
}
});
api.set('port', 3000);
var server = http.createServer(api);
server.listen(api.get('port'), function() {
console.log("Express server listening on port " + api.get('port'));
});
BTW there is no way to test it like like this const x = jwt.verify(token, 'dsfklgj', function (err, decoded) {. Either write it in Sync way or check condition in async callback function. In your case, x will be undefined and no guarantee when it will run.
