我们直接进入正题吧~~~
先来看下效果图

那么前端代码呢~~~
不着急，这就双手奉上哈~~

<a-col :span="12">
        <div class="login-body">
          <a-form

            </a-tabs>

            <a-form-item style="margin-top:24px">
              <a-button
                size="large"

handleSubmit(e) {
      /*
      *@Param 防止冒泡
      */
      e.preventDefault()
      const {
        form: { validateFields },
        state,

              state.loginBtn = false

          setTimeout(() => {
            state.loginBtn = false
          }, 600)
        }
      })
    }     

具体走的Logig方法只是参考哈：

Login({
      commit
    }, userInfo) {
      return new Promise((resolve, reject) => {
        login(userInfo).then(response => {
          const result = response.data
          // eslint-disable-next-line no-unused-vars
          const authorities = 'login'
          // if (result.authorities && result.authorities.length > 0) {
          if (authorities || authorities.length > 0) {
            Vue.ls.set(MENU, authorities, null)
            // commit('SET_AUTH', result.authorities)
            commit('SET_INFO', result.user)
          } else {
            reject(new Error('你没有权限，请联系管理员'))
          }

          commit('SET_NAME', {
            // name: result.user.name,
            name: '123',
            welcome: welcome()
          })
          // commit('SET_AVATAR', result.user.avatar)
          commit('SET_AVATAR', '123')
          resolve(response)
        }).catch(error => {
          reject(error)
        })
      })
    },
    // 退出
    Logout({
      commit,
      state
    }) {
      return new Promise((resolve) => {
        logout(state.token).then(() => {
          resolve()
        }).catch(() => {
          resolve()
        }).finally(() => {
          commit('SET_TOKEN', '')
          commit('SET_ROLES', [])
          Vue.ls.remove(ACCESS_TOKEN)
        })
      })
    }

  }

以上流程只是仅供参考哈~~~只是个人觉得把重要的逻辑所罗列出来而已。若是觉得那里有问题，可以留言，大家一起进步，谢谢来客的查看。共勉！！！
