Question

我收到的错误消息是

“跨域请求被阻止：同源策略禁止读取http://localhost:5000/user/login上的远程资源。（原因：CORS标头'Access-Control-Allow-Origin'丢失）。“

http-header.js

"import axios from 'axios';

export default axios.create({
  baseURL: "http://localhost:5000",
  headers: {
    'Content-type': 'application/json',
    'Access-Control-Allow-Origin': '*'
  }
})

AuthService.js

import axios from '../http-header.js'

export default {
  login : user => {
    return axios.post('/user/login', user)
    .then(res => {
      if(res.status !== 401)
        return res.json().then(data => data)
      else {
        return {isAuthenticated: false, user: {username: "", role: ""}}
      }
    })
  }
}

Answer 1

您必须将'Access-Control-Allow-Origin': '*'添加到您的后端。

无法使用axios发出POST请求
