从 axios 访问不记名令牌

Question

What code can I use to access a bearer token that's been stored in localStorage?

const apiClient = axios.create({
  baseURL: 'http://localhost:5000/api/v1',
  withCredentials: false,
  headers: {
    Accept: 'application/json',
    'Content-Type': 'application/json'.
    Authorization: ???
  }
});

I'm having trouble sending auth headers using a axios Service. When I hardcode the existing bearer token it works, but how can I dynamically access that for each user as it changes?

This is what worked! Thanks to DigitalDrifter for showing me the getItem function in localStorage.

I've been storing the bearer token in 'user' state, so I retrieved the object, parsed it, then inserted it into the Authorization header.

const user = JSON.parse(localStorage.getItem('user'));
const token = user.token;

const apiClient = axios.create({
  baseURL: 'http://localhost:5000/api/v1',
  withCredentials: false,
  headers: {
    Accept: 'application/json',
    'Content-Type': 'application/json',
    Authorization: `Bearer ${token}`
  }
});

A request interceptor can be used to set the Authorization header prior to each outgoing request.

// Add a request interceptor
axios.interceptors.request.use(function (config) {
    let token = localStorage.getItem('bearer_token')

    if (token) {
        config.headers.Authorization = `Bearer ${token}`
    }


    return config;
  }, function (error) {
    // Do something with request error
    return Promise.reject(error);
  });
