#鸿蒙通关秘籍#如何使用TaskPool处理同步任务？

在鸿蒙开发中，TaskPool适用于处理相对独立的同步任务。以下是实现步骤：

1. 定义并发函数：创建一个内部调用同步方法的函数。

   typescript @Concurrent async function func(num: number): Promise<number> { let tmpNum: number = Handle.syncSet(num); console.info("this is Child_Thread"); return Handle.syncSet2(tmpNum); }

2. 创建和执行任务：实例化任务，并调用execute()进行执行。

   typescript async function asyncGet(): Promise<void> { let task: taskpool.Task = new taskpool.Task(func, 1); let task2: taskpool.Task = new taskpool.Task(func, 2); let res: number = await taskpool.execute(task) as number; let res2: number = await taskpool.execute(task2) as number; console.info("taskpool: task res is: " + res); console.info("taskpool: task res2 is: " + res2); }

3. 调用并发操作：在UI交互中执行并发任务。

   typescript @Entry @Component struct Index { @State message: string = 'Hello World';

   build() { Row() { Column() { Text(this.message) .fontSize(50) .fontWeight(FontWeight.Bold) .onClick(async () => { asyncGet(); let num: number = Handle.syncSet(100); console.info("this is Main_Thread!"); }); }.width('100%').height('100%'); } } }
