常见问题
邮箱认证失败怎么办?
- 检查
SMTP_USER和SMTP_PASS是否正确 - 对于QQ邮箱,请使用授权码而非密码
- 确保邮箱已开启SMTP服务(通常在邮箱设置中)
如何发送给不同的收件人?
修改 .env 文件中的 DEFAULT_RECEIVER_EMAIL 配置项,或者修改代码支持动态收件人。
服务启动时报错 “KeyError” 怎么办?
确保 .env 文件中包含了所有必需的配置项,特别是:
- SMTP_HOST
- SMTP_PORT
- SMTP_USER
- SMTP_PASS
- DEFAULT_RECEIVER_EMAIL
如何修改服务端口?
在 .env 文件中设置 SERVICE_PORT 为所需端口号:
SERVICE_PORT=8080
安全建议
- 保护敏感信息:
- 不要将
.env文件提交到版本控制系统 - 将
.env添加到.gitignore文件中
- 不要将
- 使用专用邮箱:
- 创建专门用于发送邮件的邮箱账户
- 启用应用专用密码(如QQ邮箱的授权码)
- 限制访问:
- 仅在安全网络环境下运行服务
- 考虑添加API密钥验证机制
- 定期更新:
- 定期更换邮箱授权码
- 关注服务的安全更新
