+
+---
+
+## 🔧 核心实现
+
+### 1. TypeScript 类型定义
+
+**文件**: `app/types/google-oauth.ts`
+
+定义了完整的 OAuth 相关类型:
+
+```typescript
+// 基础响应接口
+export interface BaseResponse {
+ success: boolean
+ data?: T
+ error?: string
+ message?: string
+}
+
+// Google用户信息
+export interface GoogleUserInfo {
+ userId: string
+ userName: string
+ name: string
+ email: string
+ authType: 'GOOGLE' | 'LOCAL'
+ url?: string
+ isNewUser: boolean
+}
+
+// 邮箱冲突数据
+export interface EmailConflictData {
+ bindToken: string
+ existingUser: {
+ email: string
+ authType: 'LOCAL' | 'GOOGLE'
+ }
+}
+```
+
+### 2. 认证核心逻辑
+
+**文件**: `lib/auth.ts`
+
+#### 2.1 OAuth 授权流程
+
+```typescript
+export const signInWithGoogle = async () => {
+ try {
+ // 获取授权URL
+ const response = await fetch(`${JAVA_BASE_URL}/api/auth/google/authorize`, {
+ method: 'GET',
+ headers: {
+ Accept: 'application/json',
+ 'Content-Type': 'application/json',
+ },
+ })
+
+ const data: BaseResponse = await response.json()
+
+ if (data.success && data.data) {
+ // 保存state参数用于CSRF防护
+ const oauthState: OAuthState = {
+ state: data.data.state,
+ timestamp: Date.now(),
+ redirectUrl: window.location.pathname,
+ }
+ sessionStorage.setItem('google_oauth_state', JSON.stringify(oauthState))
+
+ // 重定向到Google授权页面
+ window.location.href = data.data.authUrl
+ }
+ } catch (error) {
+ console.error('Google OAuth initialization failed:', error)
+ throw error
+ }
+}
+```
+
+#### 2.2 ID Token 登录
+
+```typescript
+export const loginWithGoogleToken = async (
+ idToken: string,
+ action: 'login' | 'register' | 'auto' = 'auto'
+) => {
+ try {
+ const response = await fetch(`${JAVA_BASE_URL}/api/auth/google/login`, {
+ method: 'POST',
+ headers: {
+ Accept: 'application/json',
+ 'Content-Type': 'application/json',
+ },
+ body: JSON.stringify({ idToken, action }),
+ })
+
+ const data: BaseResponse = await response.json()
+
+ // 处理邮箱冲突
+ if (response.status === 409) {
+ const conflictData = data as unknown as BaseResponse
+ throw {
+ type: 'EMAIL_CONFLICT',
+ status: 409,
+ data: conflictData.data,
+ message: data.message || 'Email already exists',
+ }
+ }
+
+ if (!data.success || !data.data) {
+ throw new Error(data.message || 'Google login failed')
+ }
+
+ // 保存认证信息
+ setToken(data.data.token)
+ setUser(data.data.userInfo)
+
+ return data.data.userInfo
+ } catch (error) {
+ console.error('Google token login failed:', error)
+ throw error
+ }
+}
+```
+
+#### 2.3 账户绑定
+
+```typescript
+export const bindGoogleAccount = async (
+ bindToken: string,
+ idToken?: string
+) => {
+ try {
+ const token = getToken()
+ if (!token) {
+ throw new Error('User not authenticated')
+ }
+
+ const response = await fetch(`${JAVA_BASE_URL}/api/auth/google/bind`, {
+ method: 'POST',
+ headers: {
+ Accept: 'application/json',
+ 'Content-Type': 'application/json',
+ Authorization: `Bearer ${token}`,
+ },
+ body: JSON.stringify({
+ bindToken,
+ idToken,
+ confirm: true,
+ }),
+ })
+
+ const data: BaseResponse<{ token: string; message: string }> =
+ await response.json()
+
+ if (!data.success || !data.data) {
+ throw new Error(data.message || 'Account binding failed')
+ }
+
+ // 更新token
+ setToken(data.data.token)
+ return data.data
+ } catch (error) {
+ console.error('Google account binding failed:', error)
+ throw error
+ }
+}
+```
+
+### 3. UI 组件集成
+
+#### 3.1 登录页面更新
+
+**文件**: `components/pages/login.tsx`
+
+**主要更改:**
+
+- 添加 GoogleLoginButton 组件导入
+- 添加 googleLoading 状态管理
+- 实现 async/await 的 handleGoogleSignIn 函数
+- 添加 OAuth 回调错误处理
+
+```typescript
+const handleGoogleSignIn = async () => {
+ try {
+ setGoogleLoading(true)
+ setFormError('')
+ await signInWithGoogle()
+ } catch (error: any) {
+ console.error('Google sign-in error:', error)
+ setFormError(error.message || 'Google sign-in failed, please try again')
+ setGoogleLoading(false)
+ }
+}
+```
+
+#### 3.2 注册页面更新
+
+**文件**: `app/signup/page.tsx`
+
+**主要更改:**
+
+- 取消注释 GoogleLoginButton 组件
+- 添加分隔线保持 UI 一致性
+- 更新 handleGoogleSignIn 函数支持 async/await
+
+### 4. OAuth 回调处理
+
+**文件**: `app/users/oauth/callback/page.tsx`
+
+完整的 OAuth 回调处理页面,包含:
+
+#### 4.1 安全验证
+
+```typescript
+// 验证state参数防止CSRF攻击
+const savedStateStr = sessionStorage.getItem('google_oauth_state')
+if (!savedStateStr) {
+ setStatus('error')
+ setMessage('OAuth state not found. Please try again.')
+ return
+}
+
+const savedState: OAuthState = JSON.parse(savedStateStr)
+if (savedState.state !== params.state) {
+ setStatus('error')
+ setMessage('Invalid OAuth state. Possible CSRF attack detected.')
+ return
+}
+
+// 检查state是否过期(5分钟)
+if (Date.now() - savedState.timestamp > 5 * 60 * 1000) {
+ setStatus('error')
+ setMessage('OAuth session expired. Please try again.')
+ return
+}
+```
+
+#### 4.2 状态管理
+
+支持四种状态:
+
+- `loading`: 处理中
+- `success`: 登录成功
+- `error`: 登录失败
+- `conflict`: 邮箱冲突
+
+### 5. 邮箱冲突处理
+
+**文件**: `components/auth/email-conflict-modal.tsx`
+
+专门处理 HTTP 409 邮箱冲突响应的模态框组件:
+
+```typescript
+const handleBindAccount = async () => {
+ try {
+ setIsBinding(true)
+ setError('')
+ await onBindAccount(conflictData.bindToken)
+ onClose()
+ } catch (error: any) {
+ console.error('Account binding failed:', error)
+ setError(error.message || 'Account binding failed')
+ } finally {
+ setIsBinding(false)
+ }
+}
+```
+
+---
+
+## 🔒 安全机制
+
+### 1. CSRF 防护
+
+- 使用 OAuth state 参数防止 CSRF 攻击
+- state 参数存储在 sessionStorage 中
+- 回调时验证 state 参数一致性
+
+### 2. 会话管理
+
+- OAuth state 有效期为 5 分钟
+- 超时自动清理会话数据
+- 支持会话状态检查
+
+### 3. 错误处理
+
+- 完整的错误类型定义
+- 分层错误处理机制
+- 用户友好的错误提示
+
+### 4. 数据验证
+
+- TypeScript 类型安全
+- API 响应数据验证
+- 参数完整性检查
+
+---
+
+## 📊 API 接口对应
+
+| API 接口 | 实现函数 | 状态 | 说明 |
+| -------------------------------- | ------------------------ | ---- | ---------------- |
+| `GET /api/auth/google/authorize` | `signInWithGoogle()` | ✅ | 获取授权 URL |
+| `POST /api/auth/google/login` | `loginWithGoogleToken()` | ✅ | ID Token 登录 |
+| `POST /api/auth/google/bind` | `bindGoogleAccount()` | ✅ | 绑定 Google 账户 |
+| `GET /api/auth/google/status` | `getGoogleBindStatus()` | ✅ | 查询绑定状态 |
+
+---
+
+## 🎯 用户流程
+
+### 正常登录流程
+
+1. 用户点击 Google 登录按钮
+2. 系统调用`/api/auth/google/authorize`获取授权 URL
+3. 重定向到 Google OAuth 页面
+4. 用户完成授权
+5. 回调到`/users/oauth/callback`
+6. 验证 state 参数和处理授权码
+7. 登录成功,跳转到主页面
+
+### 邮箱冲突处理流程
+
+1. 用户使用 Google 登录
+2. 后端返回 HTTP 409 状态码
+3. 前端显示邮箱冲突模态框
+4. 用户选择绑定账户或返回登录
+5. 如选择绑定,调用绑定 API
+6. 绑定成功后完成登录
+
+---
+
+## 🚀 部署注意事项
+
+### 1. 环境变量配置
+
+确保以下环境变量正确配置:
+
+- `NEXT_PUBLIC_JAVA_URL`: Java 后端 API 基础 URL (默认: `https://77.app.java.auth.qikongjian.com`)
+- Google OAuth 客户端 ID 和密钥
+
+**重要说明**: 所有 Google OAuth 相关的 API 接口都使用`JAVA_BASE_URL`,与普通登录/注册接口保持一致。
+
+### 2. 回调 URL 配置
+
+在 Google Cloud Console 中配置正确的回调 URL:
+
+- 开发环境: `http://localhost:3000/users/oauth/callback`
+- 生产环境: `https://yourdomain.com/users/oauth/callback`
+
+### 3. HTTPS 要求
+
+生产环境必须使用 HTTPS 协议,确保 OAuth 安全性。
+

+### 1. 在新页面中集成 Google 登录
+
+```typescript
+import { GoogleLoginButton } from '@/components/ui/google-login-button'
+import { signInWithGoogle } from '@/lib/auth'
+
+const MyPage = () => {
+ const [googleLoading, setGoogleLoading] = useState(false)
+ const [error, setError] = useState('')
+
+ const handleGoogleSignIn = async () => {
+ try {
+ setGoogleLoading(true)
+ setError('')
+ await signInWithGoogle()
+ } catch (error: any) {
+ console.error('Google sign-in error:', error)
+ setError(error.message || 'Google sign-in failed')
+ setGoogleLoading(false)
+ }
+ }
+
+ return (
+
+ )
+}
+```
+
+### 2. 处理邮箱冲突
+
+```typescript
+import { EmailConflictModal } from '@/components/auth/email-conflict-modal'
+import { bindGoogleAccount } from '@/lib/auth'
+
+const handleEmailConflict = async (conflictData) => {
+ const [showConflictModal, setShowConflictModal] = useState(true)
+
+ const handleBindAccount = async (bindToken: string) => {
+ try {
+ await bindGoogleAccount(bindToken)
+ // 绑定成功,刷新页面或跳转
+ window.location.reload()
+ } catch (error) {
+ console.error('Binding failed:', error)
+ throw error
+ }
+ }
+
+ return (
+ setShowConflictModal(false)}
+ conflictData={conflictData}
+ onBindAccount={handleBindAccount}
+ onReturnToLogin={() => router.push('/login')}
+ />
+ )
+}
+```
+
+### 3. 检查 Google 账户绑定状态
+
+```typescript
+import { getGoogleBindStatus } from '@/lib/auth'
+
+const checkBindStatus = async () => {
+ try {
+ const status = await getGoogleBindStatus()
+ console.log('Google account bound:', status.isBound)
+ return status.isBound
+ } catch (error) {
+ console.error('Failed to check bind status:', error)
+ return false
+ }
+}
+```
+
+---
+

+
+---
+
+## 🔧 自定义配置
+
+### 1. 修改 OAuth 会话超时时间
+
+在`app/users/oauth/callback/page.tsx`中修改:
+
+```typescript
+// 当前为5分钟,可根据需要调整
+if (Date.now() - savedState.timestamp > 5 * 60 * 1000) {
+ // 改为10分钟
+ if (Date.now() - savedState.timestamp > 10 * 60 * 1000) {
+```
+
+### 2. 自定义 Google 登录按钮样式
+
+```typescript
+
+```
+
+### 3. 添加自定义错误处理
+
+```typescript
+const handleGoogleSignIn = async () => {
+ try {
+ await signInWithGoogle()
+ } catch (error: any) {
+ // 自定义错误处理逻辑
+ if (error.message.includes('network')) {
+ setError('网络连接失败,请检查网络后重试')
+ } else if (error.message.includes('timeout')) {
+ setError('请求超时,请重试')
+ } else {
+ setError('Google登录失败,请稍后重试')
+ }
+ }
+}
+```
+
+---
+
+## 📈 性能优化建议
+
+### 1. 代码分割
+
+```typescript
+// 懒加载邮箱冲突模态框
+const EmailConflictModal = lazy(() =>
+ import('@/components/auth/email-conflict-modal').then((module) => ({
+ default: module.EmailConflictModal,
+ }))
+)
+```
+
+### 2. 缓存优化
+
+```typescript
+// 缓存Google绑定状态
+const useGoogleBindStatus = () => {
+ const [status, setStatus] = useState(null)
+ const [loading, setLoading] = useState(true)
+
+ useEffect(() => {
+ const cachedStatus = localStorage.getItem('google_bind_status')
+ if (cachedStatus) {
+ setStatus(JSON.parse(cachedStatus))
+ setLoading(false)
+ }
+
+ getGoogleBindStatus().then((result) => {
+ setStatus(result)
+ localStorage.setItem('google_bind_status', JSON.stringify(result))
+ setLoading(false)
+ })
+ }, [])
+
+ return { status, loading }
+}
+```
+
+### 3. 错误重试机制
+
+```typescript
+const signInWithGoogleRetry = async (maxRetries = 3) => {
+ for (let i = 0; i < maxRetries; i++) {
+ try {
+ await signInWithGoogle()
+ return
+ } catch (error) {
+ if (i === maxRetries - 1) throw error
+ await new Promise((resolve) => setTimeout(resolve, 1000 * (i + 1)))
+ }
+ }
+}
+```

+```
+
+---
+
+## 🔄 前端集成流程
+
+### 方案一:使用 Google JavaScript SDK
+
+1. **引入 Google SDK**
+
+```html
+
+```
+
+2. **初始化 Google 登录按钮**
+
+```javascript
+function initializeGoogleSignIn() {
+ google.accounts.id.initialize({
+ client_id:
+ '847079918888-o1nne8d3ij80dn20qurivo987pv07225.apps.googleusercontent.com',
+ callback: handleGoogleResponse,
+ })
+
+ google.accounts.id.renderButton(
+ document.getElementById('google-signin-button'),
+ {
+ theme: 'outline',
+ size: 'large',
+ text: 'signin_with',
+ locale: 'zh_CN',
+ }
+ )
+}
+```
+
+3. **处理 Google 响应**
+
+```javascript
+async function handleGoogleResponse(response) {
+ try {
+ const result = await fetch('/api/auth/google/login', {
+ method: 'POST',
+ headers: {
+ 'Content-Type': 'application/json',
+ },
+ body: JSON.stringify({
+ idToken: response.credential,
+ action: 'auto',
+ }),
+ })
+
+ const data = await result.json()
+
+ if (data.success) {
+ // 登录成功
+ localStorage.setItem('token', data.data.token)
+ console.log('用户信息:', data.data.userInfo)
+ // 跳转到主页面
+ } else if (result.status === 409) {
+ // 邮箱冲突,需要处理绑定逻辑
+ handleEmailConflict(data)
+ } else {
+ // 其他错误
+ console.error('登录失败:', data.message)
+ }
+ } catch (error) {
+ console.error('请求失败:', error)
+ }
+}
+```
+
+### 方案二:使用授权 URL 重定向
+
+1. **获取授权 URL**
+
+```javascript
+async function getGoogleAuthUrl() {
+ try {
+ const response = await fetch('/api/auth/google/authorize')
+ const data = await response.json()
+
+ if (data.success) {
+ // 保存 state 参数用于验证
+ sessionStorage.setItem('google_oauth_state', data.data.state)
+ // 重定向到 Google 授权页面
+ window.location.href = data.data.authUrl
+ }
+ } catch (error) {
+ console.error('获取授权 URL 失败:', error)
+ }
+}
+```
+
+2. **处理回调(需要后端回调处理接口)**
+
+```javascript
+// 在回调页面处理授权码
+function handleGoogleCallback() {
+ const urlParams = new URLSearchParams(window.location.search)
+ const code = urlParams.get('code')
+ const state = urlParams.get('state')
+ const savedState = sessionStorage.getItem('google_oauth_state')
+
+ if (state !== savedState) {
+ console.error('State 参数不匹配,可能存在 CSRF 攻击')
+ return
+ }
+
+ // 发送授权码到后端处理
+ // 这需要后端提供相应的回调处理接口
+}
+```
+
+---
+
+## 🛡️ 安全注意事项
+
+1. **Token 安全**
+
+ - 妥善保存用户的 Sa-Token
+ - 定期刷新 Token
+ - 在请求头中正确传递 Token
+
+2. **CSRF 防护**
+
+ - 验证 state 参数
+ - 使用 HTTPS 协议
+
+3. **错误处理**
+
+ - 妥善处理各种错误情况
+ - 不要在前端暴露敏感信息
+
+4. **用户体验**
+ - 提供清晰的错误提示
+ - 处理网络异常情况
+ - 支持重试机制
