import common from '@ohos.app.ability.common';
import router from '@ohos.router'

封裝app內(nèi)的頁(yè)面之間跳轉(zhuǎn)、app與app之間的跳轉(zhuǎn)工具類(lèi)

【使用要求】

DevEco Studio 3.1.1 Release
api 9

【使用示例】

import MyRouterUtil from '../common/utils/MyRouterUtil'
MyRouterUtil.openBrowser('https://www.baidu.com')


export default class MyRouterUtil {
  //日志過(guò)濾器
  static readonly LOG: string = "====MyRouterUtil"
  /**
   * 鴻蒙APP跳轉(zhuǎn)到手機(jī)瀏覽器并打開(kāi)網(wǎng)頁(yè)
   * @param url 打開(kāi)網(wǎng)頁(yè)后展示的url地址
   */
  public static async openBrowser(url: string) {
    try {
      let want = {
        "action": "ohos.want.action.viewData",
        "entities": ["entity.system.browsable"],
        "uri": url,
        "type": "text/plain"
      }
      let context = getContext(this) as common.UIAbilityContext;
      await context.startAbility(want)
      console.info(MyRouterUtil.LOG, 'openBrowser', url)
    } catch (error) {
      console.error(MyRouterUtil.LOG, 'openBrowser', `${error.code},url：${url}`)
    }
  }

返回上一頁(yè)

public static backPage() {
    router.back()
    console.info(MyRouterUtil.LOG, 'backPage', '判斷棧內(nèi)頁(yè)面數(shù)：', router.getLength())
  }

在鴻蒙APP內(nèi)打開(kāi)網(wǎng)頁(yè)
常用來(lái)打開(kāi)隱私聲明、用戶(hù)協(xié)議等

@param url

  public static async openWeb(url: string) {
    try {
      await router.pushUrl({
        url: 'pages/Web', //這個(gè)頁(yè)面是我自己創(chuàng)建的，用于展示網(wǎng)頁(yè)。里面可根據(jù)url的參數(shù)決定是否顯示原生的標(biāo)題欄。
        params: {
          launchWebview: url
        }
      }, router.RouterMode.Standard)
      console.info(MyRouterUtil.LOG, 'openWeb', url)
    } catch (e) {
      console.error(MyRouterUtil.LOG, 'openWeb', JSON.stringify(e), 'url:', url)
    }
  }

獲取當(dāng)前內(nèi)存中，跑轉(zhuǎn)到web頁(yè)時(shí)保存的參數(shù)

public static getParamsByWeb() {
    let url = JSON.parse(JSON.stringify(router.getParams())).launchWebview
    console.info(MyRouterUtil.LOG, 'getParamsByWeb', url)
    return url
  }

跳轉(zhuǎn)到首頁(yè)，需要在首頁(yè)Index中

public static async openIndex() {
   try {
     await router.pushUrl({
       url: 'pages/Index'
     }, router.RouterMode.Single)
     console.info(MyRouterUtil.LOG, 'openIndex', 'succ')
     router.clear()
   } catch (e) {
     console.error(MyRouterUtil.LOG, 'openIndex', JSON.stringify(e))
   }
 }

跳轉(zhuǎn)到登錄頁(yè)

public static async openLogin() {
    try {
      await router.pushUrl({
        url: 'pages/Login'
      }, router.RouterMode.Standard)
      console.info(MyRouterUtil.LOG, 'openLogin', 'succ')
    } catch (e) {
      console.error(MyRouterUtil.LOG, 'openLogin', JSON.stringify(e))
    }
  }
}
