import Vue from ’vue’;import vuex from ’vuex’;import { get, post} from ’@/api’;Vue.use(vuex);export default new vuex.Store({ module: { }, state: { uploadImgUrls: [], }, mutations: { // 处理同步方法 SET_UPLOADIMG(state, imgUrl) { const tmp = state.uploadImgUrls; tmp.push(imgUrl); state.uploadImgUrls = tmp; }, DEL_UPLOADIMG(state, data) { state.uploadImgUrls = [...data]; }, }, actions: { // 处理异步方法 // 上传图片 async uploadImg({ commit }, { payload }) { let f = new FormData(); f.append(’file’, payload); const data = await post(’/upload’, f); commit(’SET_UPLOADIMG’, data); }, },});
