# IP 白名單功能說明
|
||||
|
||||
## 功能概述
|
||||
|
||||
本系統已實現完整的 IP 白名單功能,可以根據客戶端的 IP 地址來控制訪問權限。
|
||||
|
||||
## 功能特點
|
||||
|
||||
### 1. IP 顯示
|
||||
- 在頁面右上角顯示當前用戶的 IP 地址
|
||||
- 支援桌面版和手機版的不同顯示方式
|
||||
- 顯示 IP 白名單狀態(允許/拒絕)
|
||||
|
||||
### 2. IP 白名單檢查
|
||||
- 支援多種 IP 格式:
|
||||
- 單一 IP:`192.168.1.100`
|
||||
- IP 範圍:`192.168.1.0/24` (CIDR 格式)
|
||||
- 多個 IP:用逗號分隔,如 `192.168.1.100, 10.0.0.50`
|
||||
- 實時檢查每個請求的 IP 地址
|
||||
- 不在白名單內的 IP 會被拒絕訪問並顯示 403 錯誤頁面
|
||||
|
||||
### 3. 管理介面
|
||||
- 提供 `/admin/ip-whitelist` 管理頁面
|
||||
- 可以動態配置 IP 白名單
|
||||
- 顯示當前 IP 狀態和訪問權限
|
||||
|
||||
## 配置方法
|
||||
|
||||
### 1. 環境變數配置
|
||||
|
||||
在 `.env.local` 檔案中添加以下配置:
|
||||
|
||||
```bash
|
||||
# 允許訪問的IP地址或IP範圍,用逗號分隔
|
||||
ALLOWED_IPS=127.0.0.1,::1,192.168.1.0/24,10.0.0.0/8
|
||||
|
||||
# 是否啟用IP白名單檢查
|
||||
# true: 啟用IP檢查,不在白名單內的IP將被拒絕
|
||||
# false: 禁用IP檢查,允許所有IP訪問
|
||||
ENABLE_IP_WHITELIST=true
|
||||
```
|
||||
|
||||
### 2. IP 格式說明
|
||||
|
||||
#### 單一 IP
|
||||
```
|
||||
192.168.1.100
|
||||
```
|
||||
|
||||
#### IP 範圍 (CIDR 格式)
|
||||
```
|
||||
192.168.1.0/24 # 允許 192.168.1.0 - 192.168.1.255
|
||||
10.0.0.0/8 # 允許 10.0.0.0 - 10.255.255.255
|
||||
172.16.0.0/12 # 允許 172.16.0.0 - 172.31.255.255
|
||||
```
|
||||
|
||||
#### 多個 IP 或範圍
|
||||
```
|
||||
192.168.1.100,10.0.0.50,172.16.0.0/16
|
||||
```
|
||||
|
||||
## 使用步驟
|
||||
|
||||
### 1. 啟用 IP 白名單
|
||||
1. 設置 `ENABLE_IP_WHITELIST=true`
|
||||
2. 在 `ALLOWED_IPS` 中配置允許的 IP 地址
|
||||
3. 重新啟動應用程式
|
||||
|
||||
### 2. 測試功能
|
||||
1. 訪問主頁面,查看右上角的 IP 顯示
|
||||
2. 使用不在白名單內的 IP 訪問,應該會看到 403 錯誤頁面
|
||||
3. 訪問 `/admin/ip-whitelist` 查看管理介面
|
||||
|
||||
### 3. 管理 IP 白名單
|
||||
1. 訪問 `/admin/ip-whitelist` 頁面
|
||||
2. 查看當前 IP 狀態
|
||||
3. 修改白名單設置
|
||||
4. 保存設置
|
||||
|
||||
## 技術實現
|
||||
|
||||
### 1. 中間件 (middleware.ts)
|
||||
- 攔截所有請求
|
||||
- 檢查客戶端 IP 是否在白名單內
|
||||
- 拒絕不在白名單內的訪問
|
||||
|
||||
### 2. IP 工具函數 (lib/ip-utils.ts)
|
||||
- `isIpAllowed()`: 檢查 IP 是否被允許
|
||||
- `getClientIp()`: 獲取客戶端真實 IP
|
||||
- `isIpInRange()`: 檢查 IP 是否在指定範圍內
|
||||
|
||||
### 3. API 路由 (app/api/ip/route.ts)
|
||||
- 提供 IP 信息查詢接口
|
||||
- 返回當前 IP 和白名單狀態
|
||||
|
||||
### 4. IP 顯示組件 (components/ip-display.tsx)
|
||||
- 顯示當前 IP 地址
|
||||
- 顯示白名單狀態
|
||||
- 支援響應式設計
|
||||
|
||||
## 安全注意事項
|
||||
|
||||
1. **IP 偽造防護**:系統會檢查多個 IP 來源頭,包括:
|
||||
- `x-forwarded-for`
|
||||
- `x-real-ip`
|
||||
- `x-client-ip`
|
||||
- `cf-connecting-ip` (Cloudflare)
|
||||
|
||||
2. **本地開發**:開發環境中,`127.0.0.1` 和 `::1` 通常會被自動允許
|
||||
|
||||
3. **代理環境**:如果使用反向代理,請確保正確配置 IP 轉發
|
||||
|
||||
## 故障排除
|
||||
|
||||
### 1. IP 顯示不正確
|
||||
- 檢查是否在代理環境中
|
||||
- 確認 `getClientIp()` 函數的 IP 來源配置
|
||||
|
||||
### 2. 白名單不生效
|
||||
- 確認 `ENABLE_IP_WHITELIST=true`
|
||||
- 檢查 `ALLOWED_IPS` 格式是否正確
|
||||
- 重新啟動應用程式
|
||||
|
||||
### 3. 403 錯誤頁面
|
||||
- 檢查當前 IP 是否在白名單內
|
||||
- 查看瀏覽器開發者工具中的網路請求
|
||||
- 檢查伺服器日誌
|
||||
|
||||
## 開發建議
|
||||
|
||||
1. **測試環境**:建議在測試環境中先配置 `ENABLE_IP_WHITELIST=false`
|
||||
2. **IP 範圍**:使用 CIDR 格式可以更靈活地管理 IP 範圍
|
||||
3. **日誌記錄**:系統會記錄被拒絕的訪問,便於排查問題
|
||||
4. **備份配置**:建議備份 IP 白名單配置,避免誤操作

"114.33.18.13", // 岡山 Hinet
|
||||
"125.229.65.83", // 汐止
|
||||
"60.248.164.91", // 汐止
|
||||
"220.132.236.89", // 新竹
|
||||
"211.72.69.222", // 新竹
|
||||
"219.87.170.253", // 璟茂
|
||||
"125.228.50.228" // 璟茂
|
||||
];
|
||||
```
|
||||
|
||||
## 安全建議
|
||||
|
||||
1. **定期更新**:建議定期檢查和更新IP地址清單
|
||||
2. **記錄存取**:記錄所有IP的存取日誌
|
||||
3. **備用方案**:考慮設定備用的存取方式
|
||||
4. **監控異常**:監控未授權IP的存取嘗試
|
||||
5. **網路分段**:考慮使用VPN或專用網路
|
||||
|
||||
## 驗證IP格式的正則表達式
|
||||
```regex
|
||||
^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$
