## Usage
Before using the **CommonEventSubscriber** module, you must obtain a **subscriber** object by calling **CommonEvent.createSubscriber**.
```ts
getCode(callback:AsyncCallback<number>):void
importCommonEventfrom'@ohos.commonEvent';
letsubscriber;// Used to save the created subscriber object for subsequent subscription and unsubscription.
// Subscriber information.
letsubscribeInfo={
events:["event"]
};
// Callback for subscriber creation.
functioncreateCB(err,commonEventSubscriber){
if(err.code){
console.error(`createSubscriber failed, code is ${err.code}`);
