    • JWT相关

    工作内容

    • 更新用户数据

    准备工作

    无

    业务逻辑

    页面调用用户信息

    //更新文件：client/src/views/personal-panel/index.vue
...
<script>
import http from '@/utils/http'

export default {
  data () {
    return {
      loginer: {}
    }
  },
  async created () {
    const { id } = this.$store.state.loginer
    const res = await http.get(`/users/${id}`)
    this.loginer = res.data
  }
}
</script>

    在登录的时候，已经将登录用户信息存储到vuex中，通过用户ID查询用户详细信息。

    服务端查询用户服务

    // 更新文件： server/router/users.js
...
const { list, get, register, login, update } = require('../control/users');
...
  {
    path: '/:id',
    method: 'GET',
    handle: get
  },
...
    // 更新文件：server/control/users.js
async function get (ctx) {
  const { id } = ctx.params;
  try {
    const user = await userModel.findOne({
      _id: id
    }).select('+telephone +email'); //新增查询除默认外的字段
    if (user) {
      ctx.body = {
        code: '200',
        data: user,
        msg: '成功'
      }
      return;
    }
    throw('请核对参数')
  } catch (err) {
    ctx.body = {
      code: '403',
      data: null,
      msg: err.message
    }
  }
}
...
module.exports = {
...
  get,
...
}
    • 其中，userModel.findOne({_id: id})默认查出的是Schema没有设置select: false的字段，如果需要其它字段的话，需要userModel.findOne({_id: id}).select('+telephone +email');新增字段
    • 通过ctx.params获取匹配路由:id参数。

    前端展示布局

</script>
    • get方法调用/users/:id接口后，需要给用户设初始值。
    • patch方法调用/users/:id接口，更新用户信息后，要更新vuex存储的状态，更新展示的用户信息，更新弹窗初始值。

    服务端更新用户服务

    // 更新文件：server/control/users.js
...
async function update (ctx) {
  const { id } = ctx.params;
  const payload = ctx.request.body;
  try {
    await userModel.updateOne(
      {
        _id: id
      },
      {
        ...payload
      }
    );
    ctx.body = {
      code: '200',
      data: {
        id,
        ...payload
      },
      msg: '更新成功'
    }
  } catch (err) {
    ctx.body = {
      code: '403',
      data: null,
      msg: '请核查参数'
    }
  }
}
