Django中间件整合Vue拦截器的使用

//  interceptors
axios.interceptors.request.use(
  config => {
 // 获取登录成功状态保持的token
    let token = localStorage.getItem('token')
 // 如果有token就在头部加上token
    if (token) {
      config.headers['Authorization'] = token
    }
    return config
  },
  error => {
 // 如果没有token，返回错误的信息
    return Promise.reject(error.response);
  });

axios.interceptors.response.use(function (response) {
    // 在接收响应做些什么，例如跳转到登录页
    ......
    return response;
  }, function (error) {
    // 对响应错误做点什么
    return Promise.reject(error);
  });
