uni-app平台判断 | uni app判断h5 小程序 app 等不同平台

 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/'
    }
  }
}
