OpenHarmony startAbility 如何获取参数

前置条件

系统：OpenHarmony 3.1 release

SDK版本：API8

问题：通过startAbility启动页面后，如何在新页面中获取want.parameters中的参数，如：mykey0、mykey1...

import featureAbility from '@ohos.ability.featureAbility';
import wantConstant from '@ohos.ability.wantConstant'
featureAbility.startAbility(
    {
        want:
        {
            action: "action.system.home",
            entities: ["entity.system.home"],
            type: "MIMETYPE",
            flags: wantConstant.Flags.FLAG_AUTH_READ_URI_PERMISSION,
            deviceId: "",
            bundleName: "com.example.myapplication",
            /* FA模型中abilityName由package + Ability name组成 */
            abilityName: "com.example.entry.secondAbility",
            uri:"",
            parameters:
            {
                mykey0: 1111,
                mykey1: [1, 2, 3],
                mykey2: "[1, 2, 3]",
                mykey3: "xxxxxxxxxxxxxxxxxxxxxx",
                mykey4: [1, 15],
                mykey5: [false, true, false],
                mykey6: ["aaaaaa", "bbbbb", "ccccccccccc"],
                mykey7: true,
            },
        },
    },
).then((data) => {
    console.info("==========================>startAbilityForResult=======================>");
});
