设置原子化服务支持分享

原子化服务分享

UIAbility组件提供了UIAbility.onShare()生命周期方法，应用可通过此方法设置要分享的数据。其中，ohos.extra.param.key.contentTitle表示分享框中对分享内容title的描述，ohos.extra.param.key.shareAbstract表示分享框中对携带内容的摘要描述，ohos.extra.param.key.shareUrl表示服务的在线地址。以上三项分享数据均是开发者填充，且为Object对象，对象的key分别为title，abstract，url。
```
import AbilityConstant from '@ohos.app.ability.AbilityConstant';
class MyUIAbility extends UIAbility {
    onShare(wantParams) {
        console.log('onShare');
        wantParams['ohos.extra.param.key.contentTitle'] = {title: "OA"};
        wantParams['ohos.extra.param.key.shareAbstract'] = {abstract: "communication for company employee"};
        wantParams['ohos.extra.param.key.shareUrl'] = {url: "oa.example.com"};
    }
}
```

系统弹框调用abilityManager.acquireShareData()接口发起原子化服务共享，根据missionId找到对应的UIAbiltiy，调用其OnShare生命周期，收到共享数据。

import abilityManager from '@ohos.app.ability.abilityManager';
try {
    abilityManager.acquireShareData(1, (err, wantParam) => {
        if (err) {
            console.error(`acquireShareData fail, err: ${JSON.stringify(err)}`);
        } else {
            console.log(`acquireShareData success, data: ${JSON.stringify(wantParam)}`);
        }
    });
} catch (paramError) {
    console.error(`error.code: ${JSON.stringify(paramError.code)}, error.message: ${JSON.stringify(paramError.message)}`);
}
