+# mail-worker
+
+一個極簡的 Cloudflare Worker，用於接收域名郵件並提供 HTTP API 讀取。
+
+無需資料庫、無需前端、無需 JWT，部署後即可通過 API 取得最新郵件內容。
+
+## 特性
+
+- 📨 通過 Cloudflare Email Routing 接收郵件
+- 🗄️ 使用 KV 儲存，最多保留 50 封
+- 🔑 API Key 鑑權
+- 🌐 支持多個自定義域名（域名需托管在 Cloudflare）
+- 📦 僅依賴 `postal-mime`，無其他依賴
+
+## 前置條件
+
+- 域名已托管在 Cloudflare
+- 已啟用 Cloudflare Email Routing
+
+## 部署
+
+### 方式一：Cloudflare 一鍵部署
+
+[![Deploy to Cloudflare Workers](https://deploy.workers.cloudflare.com/button)](https://deploy.workers.cloudflare.com/?url=https://github.com/OWNER/REPO)
+
+點擊按鈕後，Cloudflare 會自動 Fork 此 repo 並完成代碼部署。
+
+部署完成後，還需手動完成以下兩步：
+
+**1. 建立 KV Namespace 並綁定**
+
+```bash
+wrangler kv:namespace create MAIL_KV
+```
+
+複製輸出的 `id`，前往 Cloudflare 控制台 → Workers & Pages → 你的 worker → Settings → Bindings → 新增 KV Namespace，名稱填 `MAIL_KV`，選擇剛建立的 namespace。
+
+**2. 設定環境變數**
+
+Cloudflare 控制台 → Workers & Pages → 你的 worker → Settings → Variables → 新增：
+
+| 變數名 | 值 |
+|---|---|
+| `AUTH_KEY` | 自訂一個密碼 |
+
+---
+
+### 方式二：本地 CLI 部署
+
+**1. 安裝依賴**
+
+```bash
+npm install wrangler postal-mime
+```
+
+**2. 建立 KV Namespace**
+
+```bash
+wrangler kv:namespace create MAIL_KV
+```
+
+複製輸出的 `id`，填入 `wrangler.toml`。
+
+**3. 配置 `wrangler.toml`**
+
+```toml
+[vars]
+AUTH_KEY = "換成你的密碼"
+
+[[kv_namespaces]]
+binding = "MAIL_KV"
+id = "貼上剛才的 KV ID"
+```
+
+**4. 部署**
+
+```bash
+wrangler deploy
+```
+
+**5. 設定 Email Routing**
+
+Cloudflare 控制台 → Email → Email Routing → Catch-all rule → Action: Send to Worker → 選擇 `mail-worker`
+
+## 自定義域名（可選）
+
+> 域名必須已托管在 Cloudflare，無需手動建立 DNS 記錄，Cloudflare 會自動處理並簽發 SSL。
+
+在 `wrangler.toml` 中取消注釋並填入你的子域名，支持多個：
+
+```toml
+[[routes]]
+pattern = "mail.domain-a.com"
+custom_domain = true
+
+[[routes]]
+pattern = "mail.domain-b.com"
+custom_domain = true
+```
+
+重新部署後即可通過自定義域名訪問 API。多個域名收到的郵件共用同一個 inbox，`to` 欄位可用於區分來源域名。
+
+## API
+
+所有請求需帶上 Header：`X-Auth-Key: 你的密碼`
+
+| 方法 | 路徑 | 說明 |
+|---|---|---|
+| GET | `/latest` | 取得最新一封完整郵件 |
+| GET | `/mails?limit=10` | 取得最近 N 封郵件列表（不含正文） |
+| GET | `/mail/:id` | 取得單封完整郵件（含 html/text） |
+| DELETE | `/mails` | 清空收件匣 |
+
+**範例**
+
+```bash
+# 使用自定義域名取得最新郵件
+curl https://mail.yourdomain.com/latest \
+  -H "X-Auth-Key: 你的密碼"
+
+# 回應範例
+{
+  "id": "uuid-xxxx",
+  "receivedAt": "2025-03-22T10:00:00.000Z",
+  "from": "[email protected]",
+  "to": "[email protected]",
+  "subject": "驗證碼：123456",
+  "text": "你的驗證碼是 123456",
+  "html": "<p>你的驗證碼是 123456</p>",
+  "attachments": [
+    { "filename": "report.pdf", "mimeType": "application/pdf", "size": 102400 }
+  ]
+}
+```
