分享App Linking直达应用

使用App Linking分享应用,目标设备接收后可直达应用,参见:使用App Linking实现应用间跳转

开发步骤

  1. 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

  2. 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

  3. 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())
    }
    }
  4. 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 })
    .width('87%')
    .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}`);
    });
    })
    }
    }

分享普通链接直达浏览器

普通链接分享支持将网页链接到目标设备/目标应用。

  • 目标设备接收时,通过浏览器直接打开链接。
  • 目标应用接收时,可便捷地处理链接内容。例如:将一个链接分享给畅连,发送给畅连好友。

开发步骤

  1. 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';
  2. 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
    });
  3. 额外增加一条数据。

    shareData.addRecord({
    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: '测试链接',
    description: '测试描述',
    });
  4. 启动分享面板。

    // 进行分享面板显示
    let controller: systemShare.ShareController = new systemShare.ShareController(shareData);
    let uiContext: UIContext = this.getUIContext();
    let context: common.UIAbilityContext = uiContext.getHostContext() as common.UIAbilityContext;
    controller.show(context, {
    selectionMode: systemShare.SelectionMode.SINGLE,
    previewMode: systemShare.SharePreviewMode.DEFAULT,
    }).then(() => {
    console.info('ShareController show success.');
    }).catch((error: BusinessError) => {
    console.error(`ShareController show error. code: ${error.code}, message: ${error.message}`);
    });
