ChangeLog of JS API Changes in the WantAgent

This document describes the WantAgent API changes in OpenHarmony 3.2.9.1 SP8 when compared with OpenHarmony 3.2.8.1.

cl.url.1 Trigger API Changes

trigger(agent: WantAgent, triggerInfo: TriggerInfo, callback?: Callback): void ;

This API has been deleted, because some functions have not been implemented. Your application can call the following API:

trigger(agent: WantAgent, triggerInfo: TriggerInfo, callback?: AsyncCallback): void

Change Impacts

Released JS APIs are affected. The application needs to adapt these APIs so that it can be properly compiled in the SDK environment of the new version.

Key API/Component Changes

Adaptation Guide

The following illustrates how to call the alternative trigger API in your application.

Example:

import WantAgent from '@ohos.app.ability.wantAgent';
// WantAgent object
var wantAgent;
// triggerInfo
var triggerInfo = {
        code: 0
    }
// WantAgentInfo object
var wantAgentInfo = {
    wants: [
        {
            deviceId: "deviceId",
            bundleName: "com.neu.setResultOnAbilityResultTest1",
            abilityName: "com.example.test.MainAbility",
            action: "action1",
            entities: ["entity1"],
            type: "MIMETYPE",
            uri: "key={true,true,false}",
            parameters:
            {
                mykey0: 2222,
                mykey1: [1, 2, 3],
                mykey2: "[1, 2, 3]",
                mykey3: "ssssssssssssssssssssssssss",
                mykey4: [false, true, false],
                mykey5: ["qqqqq", "wwwwww", "aaaaaaaaaaaaaaaaa"],
                mykey6: true,
            }
        }
    ],
    operationType: WantAgent.OperationType.START_ABILITIES,
    requestCode: 0,
    wantAgentFlags:[WantAgent.WantAgentFlags.UPDATE_PRESENT_FLAG]
}

// getWantAgent callback
function getWantAgentCallback(err, data) {
    if (err == undefined) {
        wantAgent = data;
    } else {
        console.info('getWantAgent failed' + JSON.stringify(wantAgent));
    }
    // getUid callback
    function triggerCallback(err, data) {
        if(err) {
            console.info('getUid failed!' + err.code + err.message);
        } else {
            console.info('getUid ok!' + JSON.stringify(data));
        }
    }
    try {
        WantAgent.trigger(wantAgent, triggerInfo, triggerCallback);
    } catch(err) {
        console.info('getUid failed!' + err.code + err.message);
    }
}
try{
    WantAgent.getWantAgent(wantAgentInfo, getWantAgentCallback);
} catch(err){
    console.info('getWantAgent failed!' + err.code + err.message);
}
