How do I obtain files in the rawfile directory through ResourceManager?

Solution

You can use getRawFileList in @ohos.resourceManager to obtain all files in the rawFile directory. Refer to the code snippet below.

import { BusinessError } from '@kit.BasicServicesKit';

// Passing in '' indicates obtaining a list of files in the root directory of rawfile
try {
  let context = AppStorage.get('context') as UIContext;
  context.getHostContext()!.resourceManager.getRawFileList('', (error: BusinessError, value: Array<string>) => {
    if (error != null) {
      console.error(`callback getRawFileList failed, error code: ${error.code}, message: ${error.message}.`);
    } else {
      let rawFile = value;
    }
  });
} catch (error) {
  let code = (error as BusinessError).code;
  let message = (error as BusinessError).message;
  console.error(`callback getRawFileList failed, error code: ${code}, message: ${message}.`);
}
