HarmonyOS 添加通讯录功能

请参考示例如下：

import common from '@ohos.app.ability.common';
import { BusinessError } from '@kit.BasicServicesKit';

function startContact(context: common.UIAbilityContext): void {
  context.startAbility({
    bundleName: 'com.ohos.contacts',
    abilityName: 'com.ohos.contacts.MainAbility',
    parameters: {
      phoneNumber:19900000000,
      pageFlag:'page_flag_save_contact'
    }
  }).then(() => {
    console.info('successfully.');
  }).catch((err: BusinessError) => {
    console.error(`Failed Code: ${err.code}, message: ${err.message}`);
  });
}

export class Contact {
  contactsName: string;
  telephone: number;

  constructor(contactsName: string, telephone: number) {
    this.contactsName = contactsName;
    this.telephone = telephone;
  }
}
function startSMSDialog(context: common.UIAbilityContext): void {
  let params: Array<Object> = [new Contact("张三", 19900000000)];
  context.startAbilityForResult({
    bundleName: 'com.ohos.mms',
    abilityName: 'com.ohos.mms.MainAbility',
    parameters: {
      contactObjects: JSON.stringify(params),
      pageFlag: 'conversation',
      content: "短信内容"
    }
  }).then(() => {
    console.info('successfully.');
  }).catch((err: BusinessError) => {
    console.error(`Failed Code: ${err.code}, message: ${err.message}`);
  });
}
