      code: ''
    }
  },

  created() {
    this.code = this.getQueryStringByName('code')
    // if (!getLocalStorage('openId')) {
    //   this.login()
    // }
  },

    login() {
      return new Promise((resolve, reject) => {
        if (!this.code && !getLocalStorage('openId')) {

          window.location.href = url
        } else {
