后端的代码利用postman是正常的，能存cookies。但是axios登录成功，就cookies保存不成功，不知道哪里出问题了。

import axios from "axios";

axios.defaults.withCredentials = true
axios.defaults.timeout = 10000
axios.defaults.headers.post['Content-Type'] = 'application/x-www=form-urlencoded'

export default {
    //get请求
    requestGet(url, params = {}) {
        return new Promise(((resolve, reject) => {
            axios.get(url, params).then(res => {
                resolve(res.data)
            }).catch(error => {
                reject(error)
            })
        }))
    },
    //post
    requestPost(url, params = {}) {
        return new Promise(((resolve, reject) => {
            axios.post(url, params).then(res => {
                resolve(res.data)
            }).catch(error => {
                reject(error)
            })
        }))
    }

import http from './http'

//解析token
export const checkToken = () => {
    return http.requestGet('/user/check_user_login')
}
//登录
export const doLogin = (captcha, name, password) => {
    return http.requestPost('/user/login?' + 'captcha=' + captcha + '&name=' + name + '&password=' + password)
}

//处理结果
doLogin(this.loginInfo.verifyCode, this.user.userName, this.user.password).then(result => {
  if (result.code === 200) {
    //成功，跳转
    this.toastMsg(result.message, 'success')
    this.$router.push({path: '/dashboard'});
  } else {
    //失败
    this.updateVerifyCode()
    this.toastMsg(result.message, 'error')
  }
}).catch(error => {
  console.log(error.message)
});
