推荐使用条件编译，少用条件判断
// @/utils/EPlatform.ts
/**枚举EPlatform*/
export enum EPlatform { /**App*/ AppPlus = ‘APP-PLUS‘, /**App nvue*/ AppPlusNvue = ‘APP-PLUS-NVUE‘, /**H5*/ H5 = ‘H5‘, /**微信小程序*/ MpWeixin = ‘MP-WEIXIN‘, /**支付宝小程序*/ MpAlipay = ‘MP-ALIPAY‘, /**百度小程序*/ MpBaidu = ‘MP-BAIDU‘, /**字节跳动小程序*/ MpToutiao = ‘MP-TOUTIAO‘, /**QQ小程序*/ MpQq = ‘MP-QQ‘, /**360小程序*/ Mp360 = ‘MP-360‘, /**微信小程序/支付宝小程序/百度小程序/字节跳动小程序/QQ小程序/360小程序*/ Mp = ‘MP‘, /**快应用通用(包含联盟、华为)*/ QuickappWebview = ‘quickapp-webview‘, /**快应用联盟*/ QuickappWebviewUnion = ‘quickapp-webview-union‘, /**快应用华为*/ QuickappWebviewHuawei = ‘quickapp-webview-huawei‘,}
// @/utils/Platform.ts
/**类型Platform*/import {EPlatform} from "@/utils/EPlatform";/**使用条件编译获取平台信息*/function ifDefPlatform(): EPlatform { let platform: EPlatform //#ifdef APP-PLUS platform = EPlatform.AppPlus; //#endif //#ifdef APP-PLUS-NVUE platform = EPlatform.AppPlusNvue; //#endif //#ifdef H5 platform = EPlatform.H5; //#endif //#ifdef MP-WEIXIN platform = EPlatform.MpWeixin; //#endif //#ifdef MP-ALIPAY platform = EPlatform.MpAlipay; //#endif //#ifdef MP-BAIDU platform = EPlatform.MpBaidu; //#endif //#ifdef MP-TOUTIAO platform = EPlatform.MpToutiao; //#endif //#ifdef MP-QQ platform = EPlatform.MpQq; //#endif //#ifdef MP-360 platform = EPlatform.Mp360; //#endif //#ifdef MP platform = EPlatform.Mp; //#endif //#ifdef quickapp-webview platform = EPlatform.QuickappWebview; //#endif //#ifdef quickapp-webview-union platform = EPlatform.QuickappWebviewUnion; //#endif //#ifdef quickapp-webview-huawei platform = EPlatform.QuickappWebviewHuawei; //#endif return platform}/**平台类型*/export const Platform: EPlatform = ifDefPlatform()/**默认导出平台类型*/export default Platform/**App*/export const isAppPlus = Platform == EPlatform.AppPlus/**App nvue*/export const isAppPlusNvue = Platform == EPlatform.AppPlusNvue/**H5*/export const isH5 = Platform == EPlatform.H5/**微信小程序*/export const isMpWeixin = Platform == EPlatform.MpWeixin/**支付宝小程序*/export const isMpAlipay = Platform == EPlatform.MpAlipay/**百度小程序*/export const isMpBaidu = Platform == EPlatform.MpBaidu/**字节跳动小程序*/export const isMpToutiao = Platform == EPlatform.MpToutiao/**QQ小程序*/export const isMpQq = Platform == EPlatform.MpQq/**360小程序*/export const isMp360 = Platform == EPlatform.Mp360/**微信小程序/支付宝小程序/百度小程序/字节跳动小程序/QQ小程序/360小程序*/export const isMp = Platform == EPlatform.Mp/**快应用通用(包含联盟、华为)*/export const isQuickappWebview = Platform == EPlatform.QuickappWebview/**快应用联盟*/export const isQuickappWebviewUnion = Platform == EPlatform.QuickappWebviewUnion/**快应用华为*/export const isQuickappWebviewHuawei = Platform == EPlatform.QuickappWebviewHuawei
使用
// @/utils/Config.ts
import {EPlatform} from ‘./EPlatform‘;import {isH5, Platform} from ‘@/utils/Platform‘/**配置信息*/export default class Config { /**http请求根目录*/ static get httpBaseUrl(): string { if (isH5) { return ‘/‘ } else { return ‘http://demo.cn/‘ } }}
