@ohos.wantAgent (WantAgent模块)(系统接口)

WantAgent模块提供了创建WantAgent实例、获取实例的用户ID、获取want信息、比较WantAgent实例和获取bundle名称等能力。

说明：

本模块首批接口从API version 7开始支持，从API version 9废弃，替换模块为@ohos.app.ability.wantAgent。后续版本的新增接口，采用上角标单独标记接口的起始版本。

当前页面仅包含本模块的系统接口，其他公开接口参见@ohos.wantAgent (WantAgent模块)。

导入模块

import WantAgent from '@ohos.wantAgent';

WantAgent.getWant

getWant(agent: WantAgent, callback: AsyncCallback<Want>): void

获取WantAgent中的Want(callback形式)。

系统能力：SystemCapability.Ability.AbilityRuntime.Core

系统API：该接口为系统接口，三方应用不支持调用。

参数：

示例：

import WantAgent, { WantAgent as _WantAgent} from '@ohos.wantAgent';
import Want from '@ohos.app.ability.Want';
import { BusinessError } from '@ohos.base';

//wantAgent对象
let wantAgent: _WantAgent;

//getWantAgent回调
function getWantAgentCallback(err: BusinessError, data: _WantAgent) {
	console.info('==========================>getWantAgentCallback=======================>');
    if (err.code == 0) {
    	wantAgent = data;
    } else {
        console.error('getWantAgent failed, error: ' + JSON.stringify(err));
        return;
    }

    //getWant回调
    let getWantCallback = (err: BusinessError, data: Want) => {
        console.info('==========================>getWantCallback=======================>');
    }
    WantAgent.getWant(wantAgent, getWantCallback);
}
