vue中promise怎么用？

Question

//登录

      this.$store.dispatch("Login", this.loginForm).then(info => {          this.loginloading = false;          return new Promise((resolve, reject) => {          //登录成功后获取token
            GetAssessTokenInfo(name, psd)
              .then(response => {                  
                resolve(response);
              })
              .catch(error => {
                reject(error);
              });
          });
        })
        .catch(() => {
        });

我想在登录成功后的回调里，发送获取token的协议，正确的promise写法该怎么写？

store.jsimport { login  } from '@/api/user'  const user = {  state: {    token: ''   },  mutations: {    SET_TOKEN: (state, data) => {       state.token= data     }   },  actions: {     Login({ commit }, userInfo) {      return new Promise((resolve, reject) => {         login(userInfo)           .then(response => {           const data = response.data            commit('SET_TOKEN', data.token)             resolve(response )           })           .catch(error => {             reject(error)           })       })     },    // 前端 登出 清除本地token 不访问接口     FedLogOut({ commit }) {      return new Promise(resolve => {         commit('SET_TOKEN', '')                resolve()       })     }   } }export default user调用 this.$store.dispatch("Login", this.loginForm).then(info => {  // 你的代码 }).catch(err=>{});
