mongodb - 未捕获( promise )TypeError : Cannot use 'in' operator to search for 'validateStatus' in

Question

我得到 ** Uncaught (in promise) TypeError: Cannot use 'in' operator to search for 'validateStatus' in 5f8425a33a14f026f80133ed** 其中 5f8425a33a14f026f80133ed 是传递给 axios url 的 id

我想根据用户 ID 显示服务。我的 url 在 postman 中完美运行，但是当我从 veux 商店访问它时，它给出了一个错误。

services.js(商店)

import axios from 'axios';

const state = {
    services : {},
    status: '',
    error: null
};

const getters = {
    services : state => { return state.services }
};

const actions = {
      async fetchServices({commit}, userId) {
        let res = await axios.get('http://localhost:5000/api/services/displayUser' , userId)
        commit('setProducts', res.data)
        return res;          
    }
};

const mutations = {
    setProducts (state, items) {
        state.services= items
    },
};

export default {
    state,
    actions,
    mutations,
    getters
};

这就是我调用操作的方式:

computed: {
      ...mapGetters(["services"]),
    }, 
  methods: {
    ...mapActions(["fetchServices"]),
    getData(){
      this.fetchServices(this.user._id)
    },
  },
    async created() {
      await this.getProfile();
      await this.getData();
    }

axios路由定义为

router.get('/displayUser', (req,res) => {
    const query = user =  req.body ;
    Services.find(query)
        .exec((err, services) => res.json(services))
})

GET 请求不应该有正文。使用查询参数，在路径中指定一个 id，或者使用 POST 请求。在查询参数的情况下，这可能看起来像这样:

let res = await axios.get('http://localhost:5000/api/services/displayUser' , { params: { userId })

router.get('/displayUser', (req,res) => {
    const query = user =  req.query;
    Services.find(query)
        .exec((err, services) => res.json(services))
})
