#鸿蒙通关秘籍#如何在HarmonyOS中使用scanBarcode模块进行扫码？

在HarmonyOS中，可以使用scanBarcode模块的startScanForResult方法，通过设置扫码参数启动扫码功能，并通过Promise异步获取结果。以下是一个简单的例子:

import { scanBarcode, scanCore } from '@kit.ScanKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@kit.BasicServicesKit';

let options = { scanTypes: [scanCore.ScanType.ALL], enableMultiMode: true, enableAlbum: true };

scanBarcode.startScanForResult(getContext(this), options).then((result) => {
  hilog.info(0x0001, '[Scan Sample]', `Succeeded in getting ScanResult by promise with options, result is ${JSON.stringify(result)}`);
}).catch((error) => {
  hilog.error(0x0001, '[Scan Sample]', `Failed to get ScanResult. Code: ${error.code}, message: ${error.message}`);
});
