如何从节点数据发送到localStorage React？

Question

node

const LocalStorage = require ('node-localstorage').LocalStorage;
localStorage = new LocalStorage('./localStorage');
localStorage.setItem('username', user.name);
localStorage.setItem('token', user.token)

---

react

const author = localStorage.getItem('username')
const token = localStorage.getItem('token')

In react console.log(localStorage) // {}

PS: maybe need send from react to node GET request?

  fetch('/api', {
    method: 'GET'

Answer 1

I Assume that you are trying to make request along with the token that you have saved in locastorage . for that you have to add Authorization headers. like

const token = localStorage.getItem('token')

fetch('https://example.com/endpoint', {
  method: 'GET',
  headers: {
    'Authorization': token
  }  
})

to get the token create a specific route like first you need to import
import jwt from 'jwt-simple';

Then

app.post('/login',function(req,res,next){
   res.send({token:jwt.encode({sub:user.id,iat:timpestamp},SecretKey)});
});

where SecretKey is the key defined to encryption and here the userId with time is taken to generate the token
