反应axios 401未经授权

尝试验证用户时出现401错误。只是为了给出上下文，React正在使用Express服务器，并使用Passport进行身份验证。 React有一个8001端口，而Express服务器有8000端口。

GET / api / users / user 401 2.167 ms - 59

其他获取请求工作。例如

应对

export const getUser = () => {

    return async (dispatch) =>{
        Axios.get('/api/users/user')
        .then( (res) => {
            console.log(res.data);
            localStorage.setItem('auth', res.data.authenticated);
            dispatch({type: GET_USER, res});
        }).catch( (err) => {
            console.log(err);
        })

回答如下：

你正面对这个因为你的req.user是空的，这就是为什么它进入else语句并返回你要返回的Unauthorized。

检查服务器控制台是否打印任何console.log(res.locals.user);

发送您的auth token与这样的标题

headers : {
  'Content-Type' : 'application/json',
  'Accept' : 'application/json',
  'Authorization' : 'Bearer <token_here>'
}

更新

您的请求将始终返回401 unauthorized。
