Nodejs redis使用redis- delete -通配符前缀删除密钥集不起作用

const redis = require('redis');
const client = redis.createClient();

function deleteKeysWithPrefix(prefix) {
  return new Promise((resolve, reject) => {
    let cursor = '0';
    let deletedKeys = 0;

    const scanCallback = (err, reply) => {
      if (err) {
        reject(err);
        return;
      }

      const [newCursor, keys] = reply;
      cursor = newCursor;

      const deleteCallback = (err, numDeleted) => {
        if (err) {
          reject(err);
          return;
        }

        deletedKeys += numDeleted;
        if (cursor === '0') {
          resolve(deletedKeys);
        } else {
          client.scan(cursor, 'MATCH', prefix, 'COUNT', 100, scanCallback);
        }
      };

      if (keys.length > 0) {
        client.del(keys, deleteCallback);
      } else {
        deleteCallback(null, 0);
      }
    };

    client.scan(cursor, 'MATCH', prefix, 'COUNT', 100, scanCallback);
  });
}

// 使用示例
const prefix = 'mykey:*';
deleteKeysWithPrefix(prefix)
  .then((deletedKeys) => {
    console.log(`Deleted ${deletedKeys} keys`);
  })
  .catch((err) => {
    console.error('Error:', err);
  });
