验证示例代码同源–异常场景1

ID无嵌套，存在空行

代码不一致（空行）

const promise: Promise<number> = new Promise((resolve: Function, reject: Function) => {
  setTimeout(() => {
    const randomNumber: number = Math.random();
    if (randomNumber > 0.5) {
      resolve(randomNumber);

    } else {
      reject(new Error('Random number is too small'));
    }
  }, 1000);
})

docs文档中的ID在Sample中不存在(不匹配)

const promise: Promise<number> = new Promise((resolve: Function, reject: Function) => {
  setTimeout(() => {
    const randomNumber: number = Math.random();
    if (randomNumber > 0.5) {
      resolve(randomNumber);
    } else {
      reject(new Error('Random number is too small'));
    }
  }, 1000);
})

引用部分代码（Exclude字段）

注释不一致（新增注释），代码内容一致

//新增注释
// 开始--async_await_sync_operation
async function myAsyncFunction(): Promise<string> {
  const result: string = await new Promise((resolve: Function) => {
    setTimeout(() => {
      resolve('Hello, world!');
    }, 3000);
  });
  console.info(result); // 输出： Hello, world!
  return result;
}

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

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(async () => {
            let res = await myAsyncFunction();
            console.info('res is: ' + res);
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
// 结束--async_await_sync_operation

docs代码中未去除Exclude字段

import { taskpool } from '@kit.ArkTS';

// 跨线程并发任务
@Concurrent
async function produce(): Promise<number> {
  // 添加生产相关逻辑
  console.info('producing...');
  return Math.random();
}

class Consumer {
  public consume(value: Object) {
    // 添加消费相关逻辑
    console.info('consuming value: ' + value);
  }
}

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

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
        Button() {
          Text('start')
        }.onClick(() => {
          let produceTask: taskpool.Task = new taskpool.Task(produce);
          let consumer: Consumer = new Consumer();
          for (let index: number = 0; index < 10; index++) {
            // 执行生产异步并发任务
            taskpool.execute(produceTask).then((res: Object) => {
              consumer.consume(res);
            }).catch((e: Error) => {
              console.error(e.message);
            })
          }
          this.message = 'success';
        })
        .id('button')
        .width('20%')
        .height('20%')
      }
      .width('100%')
    }
    .height('100%')
  }
}

嵌套的ID，docs中不含嵌套部分(修改4的部分，是否因为空行导致的报错，此文档中，已经取消了空行)

import { BusinessError } from '@kit.BasicServicesKit';
promise.then((result: number) => {
  console.info(`Random number is ${result}`);
}).catch((error: BusinessError) => {
  console.error(error.message);
});
