HarmonyOS鸿蒙Next中fs.access()这个方法能检查路径是否存在吗

可以检查，可以参考demo

import { BusinessError } from '@ohos.base';
import { common } from '@kit.AbilityKit';
import fs from '@ohos.file.fs';

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

  build() {
    Row() {
      Column() {
        Text(this.message).fontSize(50).fontWeight(FontWeight.Bold).onClick(() => {
          let context = getContext(this) as common.UIAbilityContext;
          let pathDir = context.filesDir;
          let filePath = pathDir
          try {
            let res = fs.accessSync(filePath);
            if (res) {
              console.info("file exists" + filePath);
            } else {
              console.info("file not exists");
            }
          } catch (error) {
            let err: BusinessError = error as BusinessError;
            console.error("accessSync failed with error message: " + err.message + ", error code: " + err.code);
          }
        })
      }.width('100%')
    }.height('100%')
  }
}
