  • 数据库查询: POST https://api.weixin.qq.com/tcb/databasequery
  • 数据库更新: POST https://api.weixin.qq.com/tcb/databaseupdate
  • 数据库删除: POST https://api.weixin.qq.com/tcb/databasedelete

数据库集合

  • ax_join: 预约记录表
    • JOIN_ID: 预约记录ID
    • JOIN_USER_ID: 用户ID
    • JOIN_MEET_ID: 预约项目ID
    • JOIN_MEET_TITLE: 预约项目标题
    • JOIN_STATUS: 预约状态
    • JOIN_REASON: 取消理由
    • 其他字段...

安全注意事项

  1. 环境变量保护: 确保微信AppSecret等敏感信息通过环境变量设置,不要硬编码在代码中

  3. 操作日志: 服务器会记录所有API调用,便于审计
  4. 数据备份: 删除操作不可撤销,建议定期备份重要数据

故障排除

常见错误

  1. AccessToken不合法 (40014)

    • 检查AppID和AppSecret是否正确
    • 确认IP白名单设置
  2. AccessToken过期 (42001)

    • 服务器会自动刷新token,如持续出现请检查系统时间
  3. 数据库查询失败

    • 检查云环境ID是否正确
    • 确认数据库集合是否存在

调试模式

设置环境变量启用调试日志:

LOG_LEVEL=debug npm start
