vue+vuex+axio从后台获取数据存入vuex实现组件之间共享数据

npm install vuex --save-dev

import store from './store/index'

 store,
 template: '<App/>',
 render: (createElement) => createElement(App)
})

        resolve(response.data);
      })
      .catch((error) => {
       console.log(error)
        reject(error)
      })
  })
}
