npm i axios
注意:這里的安裝命令就是默認安裝最新版本的axios
代碼如下:
export const errorCodeType = function(code:string):string{ let errMessage:string = "未知錯誤" switch (code) { case 400: errMessage = '錯誤的請求' break case 401: errMessage = '未授權,請重新登錄' break case 403: errMessage = '拒絕訪問' break case 404: errMessage = '請求錯誤,未找到該資源' break case 405: errMessage = '請求方法未允許' break case 408: errMessage = '請求超時' break case 500: errMessage = '服務器端出錯' break case 501: errMessage = '網絡未實現' break case 502: errMessage = '網絡錯誤' break case 503: errMessage = '服務不可用' break case 504: errMessage = '網絡超時' break case 505: errMessage = 'http版本不支持該請求' break default: errMessage = `其他連接錯誤 --${code}` } return errMessage }
這里用到的element-plus大家可以參考其官網安裝即可,傳送門:
element-plus官網
安裝命令: npm install element-plus --save
代碼如下:
import axios from 'axios'; import { errorCodeType } from '@/script/utils/error-code-type'; import { ElMessage, ElLoading } from 'element-plus'; // 創建axios實例 const service = axios.create({ // 服務接口請求 baseURL: import.meta.env.VITE_APP_BASE_API, // 超時設置 // timeout: 15000, headers:{'Content-Type':'application/json;charset=utf-8'} }) let loading:any; //正在請求的數量 let requestCount:number = 0 //顯示loading const showLoading = () => { if (requestCount === 0 && !loading) { //加載中顯示樣式可以自行修改 loading = ElLoading.service({ text: "拼命加載中,請稍后...", background: 'rgba(0, 0, 0, 0.7)', spinner: 'el-icon-loading', }) } requestCount++; } //隱藏loading const hideLoading = () => { requestCount-- if (requestCount == 0) { loading.close() } } // 請求攔截 service.interceptors.request.use(config => { showLoading() // 是否需要設置 token放在請求頭 // config.headers['Authorization'] = 'Bearer ' + getToken() // 讓每個請求攜帶自定義token 請根據實際情況自行修改 // get請求映射params參數 if (config.method === 'get' && config.params) { let url = config.url + '?'; for (const propName of Object.keys(config.params)) { const value = config.params[propName]; var part = encodeURIComponent(propName) + "="; if (value !== null && typeof(value) !== "undefined") { // 對象處理 if (typeof value === 'object') { for (const key of Object.keys(value)) { let params = propName + '[' + key + ']'; var subPart = encodeURIComponent(params) + "="; url += subPart + encodeURIComponent(value[key]) + "&"; } } else { url += part + encodeURIComponent(value) + "&"; } } } url = url.slice(0, -1); config.params = {}; config.url = url; } return config }, error => { console.log(error) Promise.reject(error) }) // 響應攔截器 service.interceptors.response.use((res:any) => { hideLoading() // 未設置狀態碼則默認成功狀態 const code = res.data['code'] || 200; // 獲取錯誤信息 const msg = errorCodeType(code) || res.data['msg'] || errorCodeType('default') if(code === 200){ return Promise.resolve(res.data) }else{ ElMessage.error(msg) return Promise.reject(res.data) } }, error => { console.log('err' + error) hideLoading() let { message } = error; if (message == "Network Error") { message = "后端接口連接異常"; } else if (message.includes("timeout")) { message = "系統接口請求超時"; } else if (message.includes("Request failed with status code")) { message = "系統接口" + message.substr(message.length - 3) + "異常"; } ElMessage.error({ message: message, duration: 5 * 1000 }) return Promise.reject(error) } ) export default service;
auto-imports.d.ts放在src目錄下
注意:需要安裝yarn add unplugin-auto-import或者npm i unplugin-auto-import -D
安裝完重啟項目
代碼如下:
declare global { const computed: typeof import('vue')['computed'] const createApp: typeof import('vue')['createApp'] const customRef: typeof import('vue')['customRef'] const defineAsyncComponent: typeof import('vue')['defineAsyncComponent'] const defineComponent: typeof import('vue')['defineComponent'] const effectScope: typeof import('vue')['effectScope'] const EffectScope: typeof import('vue')['EffectScope'] const getCurrentInstance: typeof import('vue')['getCurrentInstance'] const getCurrentScope: typeof import('vue')['getCurrentScope'] const h: typeof import('vue')['h'] const inject: typeof import('vue')['inject'] const isReadonly: typeof import('vue')['isReadonly'] const isRef: typeof import('vue')['isRef'] const markRaw: typeof import('vue')['markRaw'] const nextTick: typeof import('vue')['nextTick'] const onActivated: typeof import('vue')['onActivated'] const onBeforeMount: typeof import('vue')['onBeforeMount'] const onBeforeUnmount: typeof import('vue')['onBeforeUnmount'] const onBeforeUpdate: typeof import('vue')['onBeforeUpdate'] const onDeactivated: typeof import('vue')['onDeactivated'] const onErrorCaptured: typeof import('vue')['onErrorCaptured'] const onMounted: typeof import('vue')['onMounted'] const onRenderTracked: typeof import('vue')['onRenderTracked'] const onRenderTriggered: typeof import('vue')['onRenderTriggered'] const onScopeDispose: typeof import('vue')['onScopeDispose'] const onServerPrefetch: typeof import('vue')['onServerPrefetch'] const onUnmounted: typeof import('vue')['onUnmounted'] const onUpdated: typeof import('vue')['onUpdated'] const provide: typeof import('vue')['provide'] const reactive: typeof import('vue')['reactive'] const readonly: typeof import('vue')['readonly'] const ref: typeof import('vue')['ref'] const resolveComponent: typeof import('vue')['resolveComponent'] const shallowReactive: typeof import('vue')['shallowReactive'] const shallowReadonly: typeof import('vue')['shallowReadonly'] const shallowRef: typeof import('vue')['shallowRef'] const toRaw: typeof import('vue')['toRaw'] const toRef: typeof import('vue')['toRef'] const toRefs: typeof import('vue')['toRefs'] const triggerRef: typeof import('vue')['triggerRef'] const unref: typeof import('vue')['unref'] const useAttrs: typeof import('vue')['useAttrs'] const useCssModule: typeof import('vue')['useCssModule'] const useCssVars: typeof import('vue')['useCssVars'] const useSlots: typeof import('vue')['useSlots'] const watch: typeof import('vue')['watch'] const watchEffect: typeof import('vue')['watchEffect'] } export {}
注意:需要安裝npm i unplugin-vue-components -D或者yarn add unplugin-vue-components
安裝完重啟項目
import '@vue/runtime-core' declare module '@vue/runtime-core' { export interface GlobalComponents { ElCard: typeof import('element-plus/es')['ElCard'] ElCol: typeof import('element-plus/es')['ElCol'] ElContainer: typeof import('element-plus/es')['ElContainer'] ElFooter: typeof import('element-plus/es')['ElFooter'] ElHeader: typeof import('element-plus/es')['ElHeader'] ElMain: typeof import('element-plus/es')['ElMain'] ElOption: typeof import('element-plus/es')['ElOption'] ElPagination: typeof import('element-plus/es')['ElPagination'] ElRadioButton: typeof import('element-plus/es')['ElRadioButton'] ElRadioGroup: typeof import('element-plus/es')['ElRadioGroup'] ElRow: typeof import('element-plus/es')['ElRow'] ElSelect: typeof import('element-plus/es')['ElSelect'] ElTable: typeof import('element-plus/es')['ElTable'] ElTableColumn: typeof import('element-plus/es')['ElTableColumn'] Loading: typeof import('element-plus/es')['ElLoadingDirective'] } } export {}
注意:需要安裝npm i unplugin-icons或者yarn add unplugin-icons
import { defineConfig } from 'vite'; import vue from '@vitejs/plugin-vue'; import Icons from "unplugin-icons/vite"; import IconsResolver from "unplugin-icons/resolver"; import AutoImport from "unplugin-auto-import/vite"; import Components from "unplugin-vue-components/vite"; import { ElementPlusResolver } from "unplugin-vue-components/resolvers"; import { loadEnv } from 'vite'; import path from 'path'; // 路徑 const pathSrc = path.resolve(__dirname,'src') // https://vitejs.dev/config/ export default({ command, mode }) => { return defineConfig({ plugins: [ vue(), AutoImport({ // Auto import functions from Vue, e.g. ref, reactive, toRef... // 自動導入 Vue 相關函數,如:ref, reactive, toRef 等 imports: ["vue"], // Auto import functions from Element Plus, e.g. ElMessage, ElMessageBox...

完整的環境變量配置文件.env.production和.env.development
7.1、項目根目錄的development文件內容如下
# 開發環境 VITE_APP_TITLE = "阿綿" # 端口號 VITE_APP_PORT = "3000" # 請求接口 VITE_APP_DEV_URL = "http://localhost:8088" # 前綴 VITE_APP_BASE_API = "/api"
7.2、項目根目錄下的production文件內容如下
# 開發環境 VITE_APP_TITLE = "阿綿" # 端口號 VITE_APP_PORT = "3000" # 請求接口 VITE_APP_DEV_URL = "http://localhost:8088" # 前綴 VITE_APP_BASE_API = "/api"
注意:這里還有一個PageParams全局分頁對象:
page-params.ts
代碼如下:
// 全局統一分頁參數類型聲明 declare interface PageParams { pageNum: number, pageSize: number, type?: Model, // 可選參數 readonly sort?: string // 只讀可選參數 } interface Model { type?: string } export default PageParams;
