以下是我的工作内容：
首先，我创建了一个名为mainApi.js的文件，其任务仅是与API建立连接。
mainApi.js
import axios from "@/plugins/axios";
export default {
get(url ,id){
return axios.get(`/${url}/${id}`);
},
getAll(url, filter) {
return axios.get(`/${url}`, {params: {...filter}});
},
create(url ,teBeCreated){
return axios.post(`/${url}`, teBeCreated);
},
update(url ,toBeUpdated){
return axios.put(`/${url}/${toBeUpdated.oid}`, toBeUpdated);
},
delete(url ,id){
return axios.delete(`/${url}/${id}`);
},
}
第二步：我编写了一个基类来定义存储数据所需的函数。然后其他存储模块可以继承这个类。
gate.js
import mainApi from '@/api/main'
import store from '@/store'
export default class {
constructor() {
this.state = {
view: null,
list: [],
};
this.getters = {
view: (state) => state.view,
list: (state) => state.list,
}
this.mutations = {
SET_VIEW(state, payload) {
state.view = payload;
},
SET_LIST(state, payload) {
state.list = payload;
},
UN_SET_VIEW(state) {
state.view = null;
},
UN_SET_LIST(state) {
state.list = [];
},
}
this.actions = {
get({ commit }, { url, id }) {
return new Promise((resolve, reject) => {
mainApi.get(url, id)
.then(response => {
commit('SET_VIEW', response.data.data);
resolve(response)
})
.catch(error => {
console.log("error in get method in gate store: ", error);
commit('UN_SET_VIEW');
reject(error)
})
});
},
getAll({ commit }, { url, filter }) {
return new Promise((resolve, reject) => {
mainApi.getAll(url, filter)
.then(response => {
commit('SET_LIST', response.data.data);
resolve(response)
})
.catch(error => {
console.log("error in getAll method in gate store: ", error);
commit('UN_SET_LIST');
reject(error)
})
});
},
create({ commit }, { url, params }) {
return new Promise((resolve, reject) => {
mainApi.create(url, params)
.then(response => {
resolve(response)
})
.catch(error => {
console.log("error in create method in gate store: ", error);
reject(error)
});
});
},
update({ commit }, { url, params }) {
return new Promise((resolve, reject) => {
mainApi.update(url, params)
.then(response => {
resolve(response)
})
.catch(error => {
console.log("error in update method in gate store: ", error);
reject(error)
})
})
},
delete({ commit }, { url, id }) {
return new Promise((resolve, reject) => {
mainApi.delete(url, id)
.then(response => {
resolve(response);
})
.catch(error => {
console.log("error in delete method in gate store: ", error);
reject(error)
})
});
},
}
}
第三步：现在，我们可以定义尽可能多的独立存储模块。如下所示，在每个模块中，我们只需要获取从视图检索到的数据并将其传递给mainApi（gate.js基类的函数和方法都是我们模块的一部分），并操作接收到的数据。
someStore.js
import Gate from '@/store/modules/gate'
let gate = new Gate();
const url = 'customUrl'
const gateStates = { ...gate.state }
const gateGetters = { ...gate.getters }
const gateMutations = { ...gate.mutations }
const state = {
...gateStates,
};
const getters = {
...gateGetters,
};
const mutations = {
...gateMutations,
};
const actions = {
get: ({ commit }, id) => gate.actions.get({ commit }, { url, id }),
getAll: ({ commit }) => gate.actions.getAll({ commit }, {url, filter: {}}),
create: ({ commit }, params) => gate.actions.create({ commit }, { url, params }),
update: ({ commit }, params) => gate.actions.update({ commit }, { url, params }),
delete: ({ commit }, id) => gate.actions.delete({ commit }, { url, id })
};
export default {
namespaced: true,
state,
getters,
actions,
mutations
};
最后，我们需要导入模块并将其定义为 "vuex store 模块"，如下所示：
store/index.js
import Vue from 'vue'
import Vuex from 'vuex'
import someModule from './modules/someModule'
Vue.use(Vuex)
export default new Vuex.Store({
state: {},
mutations: {},
actions: {},
modules: {
someModule
},
plugins: {}
})
在这个示例中，我使用了另一个
Promise，因为我需要直接在视图中获取服务器的响应。如果你只想在 store 中使用响应，则不需要这些 Promise，并且应该按以下方式将其删除：
在
gate.js中改为：
get({ commit }, { url, id }) {
return new Promise((resolve, reject) => {
mainApi.get(url, id)
.then(response => {
commit('SET_VIEW', response.data.data);
resolve(response)
})
.catch(error => {
commit('UN_SET_VIEW');
console.log("error in getOne method in gate store: ", error);
reject(error)
})
});
},
转换为这样
get({ commit }, { url, id }) {
mainApi.get(url, id)
.then(response => {
commit('SET_VIEW', response.data.data);
})
.catch(error => {
commit('UN_SET_VIEW');
console.log("error in getOne method in gate store: ", error);
})
},
这样，每个模块都有list和view参数，可以在你的视图中轻松调用：
someView.vue
created() {
store.dispatch('someModule/get', this.$route.params.id)
}
computed: {
view() {
return store.getters('someModule/view')
}
}
