+# Getting Started with Create React App
+
+This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+
+## Available Scripts
+
+In the project directory, you can run:
+
+### `npm start`
+
+Runs the app in the development mode.\
+Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
+
+The page will reload when you make changes.\
+You may also see any lint errors in the console.
+
+### `npm test`
+
+Launches the test runner in the interactive watch mode.\
+See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+
+### `npm run build`
+
+Builds the app for production to the `build` folder.\
+It correctly bundles React in production mode and optimizes the build for the best performance.
+
+The build is minified and the filenames include the hashes.\
+Your app is ready to be deployed!
+
+See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+
+### `npm run eject`
+
+**Note: this is a one-way operation. Once you `eject`, you can't go back!**
+
+If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
+
+Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
+
+You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
+
+## Learn More
+
+You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).

+# 邮件服务配置指南
+
+## 概述
+本系统支持通过SMTP协议发送验证码邮件，支持主流邮件服务提供商，包括QQ邮箱、Gmail、163邮箱等。
+
+## 配置步骤
+
+### 1. 创建 .env 文件
+在项目根目录 `/home/ronghanji/api/API-TRM/rhj/backend/` 下创建 `.env` 文件（如果不存在），参考 `.env.example` 文件。
+
+### 2. 邮件服务配置选项
+
+#### QQ邮箱配置（推荐）
+```bash
+MAIL_SERVER=smtp.qq.com
+MAIL_PORT=587
+MAIL_USE_TLS=true
+MAIL_USERNAME=your_email@qq.com
+MAIL_PASSWORD=your_app_password
+MAIL_DEFAULT_SENDER=your_email@qq.com
+```
+
+**QQ邮箱授权码获取方法：**
+1. 登录QQ邮箱 (https://mail.qq.com)
+2. 点击"设置" → "账户"
+3. 找到"POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务"
+4. 开启"POP3/SMTP服务"或"IMAP/SMTP服务"
+5. 按照提示发送短信验证
+6. 获得16位授权码，这个授权码就是MAIL_PASSWORD
+
+#### Gmail配置
+```bash
+MAIL_SERVER=smtp.gmail.com
+MAIL_PORT=587
+MAIL_USE_TLS=true
+MAIL_USERNAME=your_email@gmail.com
+MAIL_PASSWORD=your_app_password
+MAIL_DEFAULT_SENDER=your_email@gmail.com
+```
+
+**Gmail应用密码获取方法：**
+1. 登录Google账号管理 (https://myaccount.google.com)
+2. 启用两步验证
+3. 转到"安全性" → "应用密码"
+4. 选择"邮件"和设备类型
+5. 生成16位应用密码
+
+#### 163邮箱配置
+```bash
+MAIL_SERVER=smtp.163.com
+MAIL_PORT=25
+MAIL_USE_TLS=false
+MAIL_USERNAME=your_email@163.com
+MAIL_PASSWORD=your_email_password
+MAIL_DEFAULT_SENDER=your_email@163.com
+```
+
+**163邮箱客户端授权密码获取方法：**
+1. 登录163邮箱
+2. 点击"设置" → "POP3/SMTP/IMAP"
+3. 开启"POP3/SMTP服务"
+4. 设置客户端授权密码
+
+#### 企业邮箱配置
+```bash
+MAIL_SERVER=your_company_smtp_server
+MAIL_PORT=587
+MAIL_USE_TLS=true
+MAIL_USERNAME=your_email@company.com
+MAIL_PASSWORD=your_password
+MAIL_DEFAULT_SENDER=your_email@company.com
+```
+
+### 3. 完整的 .env 配置示例
+
+```bash
+# 数据库配置
+SQLURL=mysql+pymysql://username:password@localhost:3306/redbook
+SQLPORT=3306
+SQLNAME=redbook
+SQLUSER=root
+SQLPWD=123456
+
+# JWT密钥
+JWT_SECRET_KEY=your-jwt-secret-key-here
+
+# Flask密钥
+SECRET_KEY=your-flask-secret-key-here
+
+# 邮件服务配置（选择一种）
+MAIL_SERVER=smtp.qq.com
+MAIL_PORT=587
+MAIL_USE_TLS=true
+MAIL_USERNAME=your_email@qq.com
+MAIL_PASSWORD=your_qq_auth_code
+MAIL_DEFAULT_SENDER=your_email@qq.com
+```
+
+## 配置验证
+
+### 1. 测试邮件配置
+创建一个测试脚本来验证邮件配置是否正确：
+
+```python
+# test_email.py
+import sys
+import os
+sys.path.append(os.path.dirname(os.path.abspath(__file__)))
+
+from config import Config
+from app.functions.FAuth import FAuth
+from app.models import db
+from app import create_app
+
+def test_email_config():
+    """测试邮件配置"""
+    app = create_app()
+    
+    with app.app_context():
+        # 检查配置
+        print("邮件服务器配置:")
+        print(f"MAIL_SERVER: {Config.MAIL_SERVER}")
+        print(f"MAIL_PORT: {Config.MAIL_PORT}")
+        print(f"MAIL_USE_TLS: {Config.MAIL_USE_TLS}")
+        print(f"MAIL_USERNAME: {Config.MAIL_USERNAME}")
+        print(f"MAIL_DEFAULT_SENDER: {Config.MAIL_DEFAULT_SENDER}")
+        
+        if not all([Config.MAIL_USERNAME, Config.MAIL_PASSWORD, Config.MAIL_DEFAULT_SENDER]):
+            print("❌ 邮件配置不完整！")
+            return False
+        
+        # 发送测试邮件
+        auth = FAuth(db.session)
+        result = auth.send_verification_email(
+            email="test@example.com",  # 替换为您的测试邮箱
+            verification_type="register"
+        )
+        
+        if result['success']:
+            print("✅ 邮件配置正确，测试邮件发送成功！")
+            return True
+        else:
+            print(f"❌ 邮件发送失败: {result['message']}")
+            return False
+
+if __name__ == "__main__":
+    test_email_config()
+```
+
+### 2. 运行测试
+```bash
+cd /home/ronghanji/api/API-TRM/rhj/backend
+python test_email.py
+```
+
+## 常见问题和解决方案
+
+### 1. 认证失败 (535 Authentication failed)
+**原因：** 用户名或密码错误
+**解决方案：**
+- 检查邮箱地址是否正确
+- 确认使用的是授权码/应用密码，不是登录密码
+- QQ/163邮箱需要开启SMTP服务并获取授权码
+
+### 2. 连接超时
+**原因：** 网络问题或服务器地址错误
+**解决方案：**
+- 检查MAIL_SERVER和MAIL_PORT是否正确
+- 确认网络连接正常
+- 尝试使用不同的端口（如465用于SSL）
+
+### 3. TLS错误
+**原因：** TLS配置问题
+**解决方案：**
+- 检查MAIL_USE_TLS设置是否正确
+- 某些邮件服务器需要使用SSL（端口465）而不是TLS
+
+### 4. 发送频率限制
+**原因：** 邮件服务商限制发送频率
+**解决方案：**
+- 减少发送频率
+- 使用企业邮箱服务
+- 考虑使用专业的邮件服务（如SendGrid、阿里云邮件推送等）
+
+## 生产环境建议
+
+### 1. 安全性
+- 使用环境变量存储敏感信息
+- 定期更换邮箱密码和授权码
+- 使用专用的邮箱账号发送系统邮件
+
+### 2. 可靠性
+- 配置备用邮件服务器
+- 实现邮件发送重试机制
+- 监控邮件发送状态
+
+### 3. 性能优化
+- 使用异步邮件发送
+- 实现邮件队列
+- 限制发送频率
+
+## 专业邮件服务替代方案
+
+如果需要更高的可靠性和发送量，建议使用专业邮件服务：
+
+1. **阿里云邮件推送**
+2. **腾讯云邮件推送**
+3. **SendGrid**
+4. **Mailgun**
+
+这些服务通常提供更好的送达率和更高的发送限制。

+# Getting Started with Create React App
+
+This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+
+## Available Scripts
+
+In the project directory, you can run:
+
+### `npm start`
+
+Runs the app in the development mode.\
+Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
+
+The page will reload when you make changes.\
+You may also see any lint errors in the console.
+
+### `npm test`
+
+Launches the test runner in the interactive watch mode.\
+See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+
+### `npm run build`
+
+Builds the app for production to the `build` folder.\
+It correctly bundles React in production mode and optimizes the build for the best performance.
+
+The build is minified and the filenames include the hashes.\
+Your app is ready to be deployed!
+
+See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+
+### `npm run eject`
+
+**Note: this is a one-way operation. Once you `eject`, you can't go back!**
+
+If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
+
+Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
+
+You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
+
+## Learn More
+
+You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
