[Vue- Promise函數(shù)---參數(shù)resolve(調(diào)用.then方法)-- 參數(shù)reject(調(diào)用.catch方法)---鏈?zhǔn)浇Y(jié)構(gòu)]

// 退出登錄

    handleLogOut (a,b) {
      return new Promise((resolve, reject) => {
        logout(a,b).then(() => {
          commit('setToken', '')
          resolve()
        }).catch(err => {
          reject(err)
        })
      })
    },

其他頁(yè)面調(diào)用handleLogOut ()函數(shù)使用.then(res => {})

handleLogOut (a,b).then(res => {
  if (res.data.code === 200) {

  } else {
  
  }
})
