问题 I am currently having a problem with React and Express JS form submit function. It seems like my nodeJS running on port 5000 is receiving an empty object from my ReactJS running on port 8080 using fetch method. React : Contact.js handleSubmit(e) { e.preventDefault(); var data = { name: this.state.name, contact: this.state.contact, email: this.state.email, message: this.state.message, } var url = 'http://localhost:5000/api/insertUsers'; fetch(url, { method: 'POST', headers: { 'Content-Type':

问题 What I'm trying to do is deploy react / apollo-server full stack app to heroku. Thus I' trying to serve static client files from express/apollo-server backend, like this: const path = require('path'); const express = require('express'); const app = express(); const cors = require('cors'); const { ApolloServer } = require('apollo-server'); const { schema } = require('./schema'); const { resolvers } = require('./resolvers'); app.use(cors()); app.use(express.static('public')); app.get('*', (req,

问题 I am getting the CSRF forbidden error . However CSRF is working fine in the rest of the application like post route of logout, signUp, Signin deleteing anything et c.. But when I perform the post action in only one route `/addProduct" I am getting the error Note that I am generating my CSRF token before routes declaration. I am attaching the main file code and the front end code of addProduct. Here is my main file code where I am generating token and including it in all routes app.use

问题 I'm building an Express API and using @hapi/joi for validation. However I find myself in the following situation: if I want to validate a new user, all the properties in the schema have to be required, but if the client wants to modify a user, these properties must be optional since only the client knows what properties it will modify. So if I have this schema for new users : function validateUser(user) { const schema = Joi.object().keys({ name: Joi.string().required(), lastName: Joi.string()

问题 In my express app, generated with express-generator , I want to use the io of socket.io in some other controller files to emit data to client sockets. My approach is below, but I get the following error with that. It would be a great favor if someone can help me in this case. (node:11376) UnhandledPromiseRejectionWarning: TypeError: io.emit is not a function at F:\backend\controllers\LessonController.js:169:9 In the express apps, generated by express-generator , the process of creating the

问题 I've checked many answers on the internet but I think I'm doing some other mistake also. My question is strictly related to guarding /contribute route using JWT (which is a POST request). My API is in expressjs . First I hit /login route with correct credentials and get a token. This token I cross checked on jwt.io and it says "Invalid Signature". Here is that token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWJqZWN0IjoiNWVhZDlkOGY4N2VjMjkwMDE3YzRkODkzIiwiaWF0IjoxNjA3ODczNjY2fQ.H5RI-lOBzfJo4
