开通App Linking服务,并完成相关配置,App Linking需经过调试。参见:调试App Linking。
在应用配置文件(src/main/module.json5)的skills配置中增加关联配置。参见:声明应用关联的网站域名。
使用App Linking发起系统分享。
import { systemShare } from '@kit.ShareKit';
import { uniformTypeDescriptor as utd } from '@kit.ArkData';
import { common } from '@kit.AbilityKit';
import { image } from '@kit.ImageKit';
import { BusinessError } from '@kit.BasicServicesKit';
@Component
export default struct Index {
private async share() {
// 生成应用图标缩略图
let uiContext: UIContext = this.getUIContext();
let contextFaker: Context = uiContext.getHostContext() as Context;
let thumbnailPath = contextFaker.filesDir + '/exampleImage.jpg'; // 仅为示例 请替换正确的文件路径
let imageSource: image.ImageSource = image.createImageSource(thumbnailPath);
let imagePacker: image.ImagePacker = image.createImagePacker();
let buffer: ArrayBuffer = await imagePacker.packToData(imageSource, {
// 当前只支持'image/jpeg','image/webp'和'image/png'类型图片.
format: 'image/jpeg',
// JPEG编码中设定输出图片质量的参数,取值范围为0-100.
// 建议适当压缩,图片过大无法拉起分享.
quality: 30
});
// 构造ShareData,需配置一条有效数据信息
let shareData: systemShare.SharedData = new systemShare.SharedData({
utd: utd.UniformDataType.HYPERLINK,
// App Linking链接 仅为示例
content: 'https://sharekitdemo.drcn.agconnect.link/ZB3p',
title: '应用名称', // 不传title时 显示链接
description: '应用描述', // 不传则不显示描述内容
thumbnail: new Uint8Array(buffer) // 推荐传入应用图标 不传则显示默认html图标
});
// 进行分享面板显示
let controller: systemShare.ShareController = new systemShare.ShareController(shareData);
let context: common.UIAbilityContext = uiContext.getHostContext() as common.UIAbilityContext;
controller.show(context, {
previewMode: systemShare.SharePreviewMode.DEFAULT,
selectionMode: systemShare.SelectionMode.SINGLE
}).then(() => {
console.info('ShareController show success.');
}).catch((error: BusinessError) => {
console.error(`ShareController show error. code: ${error.code}, message: ${error.message}`);
});
}
build() {
Button('分享')
.onClick(() => this.share())
}
} 目标应用处理App Linking。参见:拉起方实现跳转指导。
import { common, OpenLinkOptions } from '@kit.AbilityKit';
import { BusinessError } from '@kit.BasicServicesKit';
@Entry
@Component
struct Index {
build() {
Button('start link', { type: ButtonType.Capsule, stateEffect: true })

.height('5%')
.margin({ bottom: '12vp' })
.onClick(() => {
let uiContext: UIContext = this.getUIContext();
let context: common.UIAbilityContext = uiContext.getHostContext() as common.UIAbilityContext;
let link: string = "https://www.example.com/programs?action=showall";
let openLinkOptions: OpenLinkOptions = {
appLinkingOnly: false
};
context.openLink(link, openLinkOptions)
.then(() => {
console.info('openlink success.');
})
.catch((error: BusinessError) => {
console.error(`openlink failed. code: ${error.code}, message: ${error.message}`);
});
})
}

导入相关模块。
import { systemShare } from '@kit.ShareKit';
import { uniformTypeDescriptor as utd } from '@kit.ArkData';
import { common } from '@kit.AbilityKit';
import { BusinessError } from '@kit.BasicServicesKit'; 构造分享数据。
// 构造ShareData,需配置一条有效数据信息
let shareData: systemShare.SharedData = new systemShare.SharedData({
utd: utd.UniformDataType.HYPERLINK,
content: 'https://www.vmall.com/index.html?cid=128688', // 仅为示例 使用时请替换为自己的链接
title: '华为商城',
description: '华为手机',
// thumbnail: new Uint8Array() // 推荐传入适合的缩略图 不传则显示默认html图标
}); 额外增加一条数据。
shareData.addRecord({

content: 'https://www.vmall.com/index.html?cid=128688', // 仅为示例 使用时请替换为自己的链接
title: '测试链接',
