1# wantAgent的JS API变更Changelog
2
3## cl.url.1.trigger类接口变更
4trigger(agent: WantAgent, triggerInfo: TriggerInfo, callback?: Callback<CompleteData>): void ;
5
6因部分功能未实现，已对其进行删除，应用可调用下面接口进行替代：
7
8 trigger(agent: WantAgent, triggerInfo: TriggerInfo, callback?: AsyncCallback<CompleteData>): void
9
10 **变更影响**
11
12影响已发布的JS接口，应用需要进行适配，才可以在新版本SDK环境正常编译通过。
13
14**关键的接口/组件变更**
15
16| OpenHarmony 3.2.8.1版本接口                                  | OpenHarmony 3.2.9.1 sp8版本接口                              |
17| ------------------------------------------------------------ | ------------------------------------------------------------ |
18| trigger(agent: WantAgent, triggerInfo: TriggerInfo, callback?: Callback<CompleteData>): void ; | trigger(agent: WantAgent, triggerInfo: TriggerInfo, callback?: AsyncCallback<CompleteData>): void |
19
20**适配指导**
21
22应用中调用替代的trigger接口可参考下列代码
23
24示例：
25
26```ts
27import WantAgent from '@ohos.app.ability.wantAgent';
28//wantAgent对象
29var wantAgent;
30// triggerInfo
31var triggerInfo = {
32        code: 0
33    }
34//WantAgentInfo对象
35var wantAgentInfo = {
36    wants: [
37        {
38            deviceId: "deviceId",
39            bundleName: "com.neu.setResultOnAbilityResultTest1",
40            abilityName: "com.example.test.MainAbility",
41            action: "action1",
42            entities: ["entity1"],
43            type: "MIMETYPE",
44            uri: "key={true,true,false}",
45            parameters:
46            {
47                mykey0: 2222,
48                mykey1: [1, 2, 3],
49                mykey2: "[1, 2, 3]",
50                mykey3: "ssssssssssssssssssssssssss",
51                mykey4: [false, true, false],
52                mykey5: ["qqqqq", "wwwwww", "aaaaaaaaaaaaaaaaa"],
53                mykey6: true,
54            }
55        }
56    ],
57    operationType: WantAgent.OperationType.START_ABILITIES,
58    requestCode: 0,
59    wantAgentFlags:[WantAgent.WantAgentFlags.UPDATE_PRESENT_FLAG]
60}
61
62//getWantAgent回调
63function getWantAgentCallback(err, data) {
64    if (err == undefined) {
65        wantAgent = data;
66    } else {
67        console.info('getWantAgent failed' + JSON.stringify(wantAgent));
68    }
69    //getUid回调
70    function triggerCallback(err, data) {
71        if(err) {
72            console.info('getUid failed!' + JSON.stringify(err.code) + JSON.stringify(err.message));
73        } else {
74            console.info('getUid ok!' + JSON.stringify(data));
75        }
76    }
77    try {
78        WantAgent.trigger(wantAgent, triggerInfo, triggerCallback);
79    } catch(err) {
80        console.info('getUid failed!' + JSON.stringify(err.code) + JSON.stringify(err.message));
81    }
82}
83try{
84    WantAgent.getWantAgent(wantAgentInfo, getWantAgentCallback);
85} catch(err){
86    console.info('getWantAgent failed!' + JSON.stringify(err.code) + JSON.stringify(err.message));
87}
88```
