In nodeJS möchte ich einen Standardordner für meine Box-API-Downloadfunktion festlegen

Question

Ich verwende das Box SDK für NodeJS und habe eine Funktion zum Herunterladen von Dateien. Ich muss nur den Download so einstellen, dass er in einem Projektunterordner abgelegt wird Ich habe die Dokumentation gelesen, kann aber keine relevanten Parameter finden

async function downloadBoxFile(fileID, fileName) {
  try {
    // Load configuration
    const config = loadConfiguration();
    const { clientID, clientSecret, enterpriseID } = config.boxConfiguration;

    // Authenticate Box client
    const boxClient = boxAuthentication(clientID, clientSecret, enterpriseID);        

    const fileReadStream = await boxClient.files.getReadStream(fileID, null, {
      fields: 'modified_at, size, sha1, owned_by'
    });

    const writeStream = fs.createWriteStream(fileName);
    fileReadStream.pipe(writeStream);

    return new Promise((resolve, reject) => {
      fileReadStream.on('end', () => {        
        writeLog('> File downloaded successfully:' + fileName);
        resolve();
      });
      fileReadStream.on('error', (error) => {
        console.log('Error downloading file:', error);
        writeLog('Error downloading file:', error);
        reject(error);
      });
    });
  } catch (error) {
    console.log('Error downloading file:', error);
    writeLog('Error downloading file:', error);
    throw error;
  }
}

我设法解决这个问题，只需将路径参数传递给函数并附加到文件名

const fullPath = path.join(folderPath, fileName);
const writeStream = fs.createWriteStream(fullPath);
fileReadStream.pipe(writeStream);
