Javascript 如何在vue.js 2上获得此.store.dispatch的响应？

我的组件如下所示：

<script>
    export default{
        props:['search','category','shop'],
        ...

        methods: {
            getVueItems: function(page) {
                this.$store.dispatch('getProducts', {q:this.search, cat:this.category, shop: this.shop, page:page}).then(response => {
                    console.log(response)
                    this.$set(this, 'items', response.body.data)
                    this.$set(this, 'pagination', response.body)
                }, error => {
                    console.error("this is error")
                })
            },
            ...
        }
    }
</script>

import { set } from 'vue'
import product from '../../api/product'
import * as types from '../mutation-types'

// initial state
const state = {
    list: {}
}

// actions
const actions = {
    getProducts ({ commit,state }, payload)
    {
        product.getProducts( payload,
            data => {
                let products = data
                commit(types.GET_PRODUCTS,{ products });
            },
            errors => {
                console.log('error load products ')
            }
        )
    }
}

// mutations
const mutations = {
    [types.GET_PRODUCTS] (state, { products }) {
        state.list = {}
        products.data.forEach(message => {
            set(state.list, message.id, message)
        })
    }
}

export default {
    state,
    actions,
    mutations
}

import Vue from 'vue'
import Resource from 'vue-resource'

Vue.use(Resource)

export default {
    // api to get filtered products
    getProducts (filter, cb, ecb = null ) {
        Vue.http.post(window.Laravel.baseUrl+'/search-result',filter)
            .then(
            (resp) => cb(resp.data),
            (resp) => ecb(resp.data)
        );
    }
}

<script>
    export default{
        props:['search','category','shop'],
        ...

        methods: {
            getVueItems: function(page) {
                const q = this.search
                const cat = this.category
                const shop = this.shop
                this.$http.get('search-result?page='+page+'&q='+q+'&cat='+cat+'&shop'+shop).then((response) => {
                    console.log(JSON.stringify(response))
                    this.$set(this, 'items', response.body.data)
                    this.$set(this, 'pagination', response.body)
                });
            },
            ...
        }
    }
</script>

然后，模块在product.js api上再次调用getProducts方法

product.js api如下所示：

<script>
    export default{
        props:['search','category','shop'],
        ...

        methods: {
            getVueItems: function(page) {
                this.$store.dispatch('getProducts', {q:this.search, cat:this.category, shop: this.shop, page:page}).then(response => {
                    console.log(response)
                    this.$set(this, 'items', response.body.data)
                    this.$set(this, 'pagination', response.body)
                }, error => {
                    console.error("this is error")
                })
            },
            ...
        }
    }
</script>

import { set } from 'vue'
import product from '../../api/product'
import * as types from '../mutation-types'

// initial state
const state = {
    list: {}
}

// actions
const actions = {
    getProducts ({ commit,state }, payload)
    {
        product.getProducts( payload,
            data => {
                let products = data
                commit(types.GET_PRODUCTS,{ products });
            },
            errors => {
                console.log('error load products ')
            }
        )
    }
}

// mutations
const mutations = {
    [types.GET_PRODUCTS] (state, { products }) {
        state.list = {}
        products.data.forEach(message => {
            set(state.list, message.id, message)
        })
    }
}

export default {
    state,
    actions,
    mutations
}

import Vue from 'vue'
import Resource from 'vue-resource'

Vue.use(Resource)

export default {
    // api to get filtered products
    getProducts (filter, cb, ecb = null ) {
        Vue.http.post(window.Laravel.baseUrl+'/search-result',filter)
            .then(
            (resp) => cb(resp.data),
            (resp) => ecb(resp.data)
        );
    }
}

<script>
    export default{
        props:['search','category','shop'],
        ...

        methods: {
            getVueItems: function(page) {
                const q = this.search
                const cat = this.category
                const shop = this.shop
                this.$http.get('search-result?page='+page+'&q='+q+'&cat='+cat+'&shop'+shop).then((response) => {
                    console.log(JSON.stringify(response))
                    this.$set(this, 'items', response.body.data)
                    this.$set(this, 'pagination', response.body)
                });
            },
            ...
        }
    }
</script>

当执行时，我在控制台上检查，响应不显示。响应未定义

如何解决错误

更新

如果我像这样使用普通ajax：

<script>
    export default{
        props:['search','category','shop'],
        ...

        methods: {
            getVueItems: function(page) {
                this.$store.dispatch('getProducts', {q:this.search, cat:this.category, shop: this.shop, page:page}).then(response => {
                    console.log(response)
                    this.$set(this, 'items', response.body.data)
                    this.$set(this, 'pagination', response.body)
                }, error => {
                    console.error("this is error")
                })
            },
            ...
        }
    }
</script>

import { set } from 'vue'
import product from '../../api/product'
import * as types from '../mutation-types'

// initial state
const state = {
    list: {}
}

// actions
const actions = {
    getProducts ({ commit,state }, payload)
    {
        product.getProducts( payload,
            data => {
                let products = data
                commit(types.GET_PRODUCTS,{ products });
            },
            errors => {
                console.log('error load products ')
            }
        )
    }
}

// mutations
const mutations = {
    [types.GET_PRODUCTS] (state, { products }) {
        state.list = {}
        products.data.forEach(message => {
            set(state.list, message.id, message)
        })
    }
}

export default {
    state,
    actions,
    mutations
}

import Vue from 'vue'
import Resource from 'vue-resource'

Vue.use(Resource)

export default {
    // api to get filtered products
    getProducts (filter, cb, ecb = null ) {
        Vue.http.post(window.Laravel.baseUrl+'/search-result',filter)
            .then(
            (resp) => cb(resp.data),
            (resp) => ecb(resp.data)
        );
    }
}

<script>
    export default{
        props:['search','category','shop'],
        ...

        methods: {
            getVueItems: function(page) {
                const q = this.search
                const cat = this.category
                const shop = this.shop
                this.$http.get('search-result?page='+page+'&q='+q+'&cat='+cat+'&shop'+shop).then((response) => {
                    console.log(JSON.stringify(response))
                    this.$set(this, 'items', response.body.data)
                    this.$set(this, 'pagination', response.body)
                });
            },
            ...
        }
    }
</script>

导出默认值{
道具：[“搜索”，“分类”，“商店]，
...
方法：{
getVueItems:函数（第页）{
const q=this.search
const cat=this.category
const shop=this.shop
这是.http.get（'search-result？page='+page+'&q='+q+'&cat='+cat+'&shop'+shop）。然后（（响应）=>{
log（JSON.stringify（响应））
this.$set（this'items'，response.body.data）
this.$set（this'pagination'，response.body）
});
},
...
}
}

它起作用了。它得到了回应

但是，为什么我使用vuex store时，它不起作用？

您应该在

操作中返回
承诺的

尝试：

或者简单地说，您可以向上传递
return Vue.http.post（）
