性能考虑

优化策略

缓存机制：使用 LRU 缓存减少重复加载
异步处理：支持并发图片处理
内存管理：及时释放不再使用的资源
网络优化：智能重试和断点续传

性能指标

指标类型	建议值	说明
单次处理时间	< 5 秒	包含下载和处理
并发处理能力	5-10 个	根据系统资源调整
内存使用	< 500MB	避免内存泄漏
磁盘空间	无限制	临时文件自动清理

故障排除指南

常见问题及解决方案

草稿相关问题

问题类型	错误码	描述	解决方案
草稿不存在	404	指定的草稿URL无效	检查草稿URL是否正确
草稿过期	404	草稿已失效	重新创建草稿
权限不足	403	无权访问草稿	检查访问权限

图片处理问题

问题类型	错误码	描述	解决方案
图片下载失败	500	网络连接问题	检查网络连接和URL有效性
图片格式不支持	400	不支持的图片格式	确保使用 JPG、PNG 等常见格式
图片尺寸无效	400	宽度或高度小于等于0	提供有效的图片尺寸

参数验证问题

问题类型	错误码	描述	解决方案
缺少必填参数	400	draft_url 或 image_infos 为空	确保提供所有必需参数
时间范围无效	400	end <= start	确保结束时间大于开始时间
透明度超出范围	400	alpha 不在 $0.0, 1.0$	使用有效范围内的透明度值

调试技巧

启用详细日志：查看详细的处理过程
检查网络连接：确保网络稳定
验证图片URL：确认图片可正常访问
监控系统资源：避免内存和磁盘空间不足
