使用云函数删除实时数据库中所有出现的UID

const tcb = require('tcb-admin-node');

exports.main = async (event, context) => {
  const app = tcb.init({
    env: 'your-env-id' // 替换为你的环境ID
  });

  const db = app.database();

  try {
    const queryResult = await db.collection('your-collection').where({
      uid: 'your-uid' // 替换为你要删除的UID
    }).get();

    const deletePromises = queryResult.data.map(async (doc) => {
      await db.collection('your-collection').doc(doc._id).remove();
    });

    await Promise.all(deletePromises);

    return {
      code: 0,
      message: '删除成功'
    };
  } catch (err) {
    return {
      code: -1,
      message: '删除失败：' + err.message
    };
  }
};
