Arouter

简介

Arouter是一款轻量且高效的适用于OpenHarmony的页面路由工具。

  • 支持页面间路由跳转;
  • 支持带参数跳转及回调;
  • 支持配置跳转拦截器;
  • 支持预处理跳转与否。

下载安装

ohpm install @ohos/arouteronactivityresult

OpenHarmony ohpm 环境配置等更多内容,请参考如何安装 OpenHarmony ohpm 包

使用说明

路由跳转

1.不传参跳转

通过Arouter.getInstance()创建路由对象,使用链式调用方法 build('')配置跳转的页面,navigation() 方法进行页面跳转。

import {Arouter} from "@ohos/arouteronactivityresult";
Arouter.getInstance()
    .build("--/--")  //需要跳转的地址
    .navigation()

2.传参跳转

在不传参跳转的基础上,跳转之前通过withParams()进行参数配置。

import {Arouter} from "@ohos/arouteronactivityresult";
Arouter.getInstance()
    .build("--/--")  //需要跳转的地址
    .withParams({index:"--"})
    .navigation()

3.路由回调

路由回调需要配合NavigationCallback接口进行,在路由前的页面实现NavigationCallback接口

import {NavigationCallback} from '@ohos/arouteronactivityresult'
var callback:NavigationCallback = {
    onInterrupt(postcard){},
    onArrival(postcard){},
    onActivityResult(data){}
}

然后将callback传入 .navigationWithCallback()中进行跳转

import {Arouter} from "@ohos/arouteronactivityresult";
Arouter.getInstance()
    .build("--")//需要跳转的地址
    .navigationWithCallback(callback)

在目标页面的onPageShow()生命周期中调用getPostcard()方法获取到指定的postcard

import router from '@ohos.router';
if (postcard == null) {
    postcard = Arouter.getInstance().getPostcard(router.getState().path + router.getState().name);
}

使用 postcard.getNavigationCallback() 方法调用对应的回调方法,即可回调源页面实现的方法

postcard.getNavigationCallback().onActivityResult(params)

路由拦截

1.配置拦截器

在拦截器中的process()方法中实现页面的拦截,通过interceptorCallback.onInterrupt()中断跳转,interceptorCallback.onContinue()继续跳转。

import {Postcard,IInterceptor,InterceptorCallback} from '@ohos/arouteronactivityresult';
var iInterceptor:IInterceptor= {
    process(postcard:Postcard, interceptorCallback:InterceptorCallback) {
        // 选择拦截的页面,若跳转时有该路径则进行拦截提示,若没有则直接跳转
        if (Postcard.getUri() == 'pages/transit') {
            // 选择弹框
            AlertDialog.show(
                {
                    message: '被拦截了,点击继续跳转',
                    primaryButton: {
                        value: '取消',
                        action: () => {
                            // 中断跳转
                            interceptorCallback.onInterrupt(postcard)
                        }
                    },
                    secondaryButton: {
                        value: '继续',
                        action: () => {
                            // 继续跳转
                            interceptorCallback.onContinue(postcard);
                        }
                    },
                }
            )
        } else {
            // 继续跳转
            interceptorCallback.onContinue(postcard);
        }
    }
}

2.注册拦截器

import {registerInterceptor} from '@ohos/arouteronactivityresult';
registerInterceptor(iInterceptor);

3.移除拦截器

import {unregisterInterceptor} from '@ohos/arouteronactivityresult';
unregisterInterceptor()

4.配置绿色通道

在跳转前使用.setGreenChannel()方法跳过拦截(true:跳过拦截)。

Arouter.getInstance()
    .build("--/--")//需要跳转的地址
    .setGreenChannel(true)
    .navigation()

5.配置预处理跳转与否

预处理:实现 PretreatmentService 接口中 onPretreatment 方法,并返回一个Boolean值(true:继续跳转,false:不跳转)。

import {PretreatmentService} from '@ohos/arouteronactivityresult';
var pretreatmentService:PretreatmentService = {
  onPretreatment(postcard:Postcard):boolean{
    return true
  }
}

在跳转前调用.setPretreatmentService() 方法,将 pretreatmentService传入 setPretreatmentService()方法中完成预处理功能。

Arouter.getInstance()
    .build(this.router)
    .setPretreatmentService(pretreatmentService)
    .navigationWithCallback(callback)
