前言\n\n在鐵人賽前半段，我們深入探討了 LINE Bot 的兩大核心功能：Richmenu(選單設置)與各種 Reply Message(回覆訊息)的訊息類型。然而在實務應用中，若要提供更豐富的互動體驗，Line 往往需要搭配 LIFF(LINE Front-end Framework)來實現更多元的應用場景。\n\n以常見的早餐店點餐網站或店家會員卡為例，使用者點擊連結後，LIFF 網頁會在 LINE 內開啟，此時已處於登入狀態。授權後即可取得使用者的 LINE 資料(如名稱、頭像)，無需額外註冊。完成操作後關閉網頁，便直接返回聊天室。\n\n> 本日程式碼的[範例連結](https:\u002F\u002Fgithub.com\u002FLING-JUN-HAO\u002Fliff-ironman\u002Ftree\u002Fday17)\n\n### LIFF 與瀏覽器技術基礎\n\n> 若 Line Bot 服務對象以年長用戶為主，需特別留意裝置相容性問題。年長用戶常使用較舊版本的手機系統，若未進行完善的相容性測試，可能導致頁面無法正常顯示或功能失效，影響使用體驗。\n\n**LIFF 瀏覽器採用各平台的原生網頁元件：**\n\n- iOS 使用 WKWebView\n- Android 使用 WebView\n\n這些底層技術直接影響系統相容性與快取策略的實作方式。快取行為受 `HTTP` 標頭控制,特別是 `Cache-Control` 等相關設定。\n\n### 創建 Line Login 頻道\n\nLINE LIFF 必須在已擁有 LINE Login 頻道的前提下才能建立，它屬於 LINE Login 服務的一部分，與先前使用的 Messaging API 是不同的頻道服務項目。因此，可以將 LINE LIFF 視為一個獨立的前端專案來進行開發與建置。\n\n![創建 LINE Login 頻道](https:\u002F\u002Fres.cloudinary.com\u002Fdseg0uwc9\u002Fimage\u002Fupload\u002Fv1759756229\u002F2025%20IT%20%E9%90%B5%E4%BA%BA%E8%B3%BD\u002FDay%2023%EF%BC%9ALINE%20LIFF%20%E7%B6%B2%E9%A0%81%E6%87%89%E7%94%A8%E9%96%8B%E7%99%BC%E5%85%A5%E9%96%80\u002F%E5%89%B5%E5%BB%BA_LINE_Login_%E9%A0%BB%E9%81%93_mt6hdy.jpg)\n\n**建置頻道時需要填寫以下必要資訊：**\n\n- Region to provide the service：選擇 Taiwan。決定服務的主要營運區域\n- Company or owner's country or region：選擇 Taiwan。填寫頻道擁有者的所在地\n- Channel name：填寫「LIFF 基礎認識」，此名稱會顯示在授權頁面上\n- Channel description：填寫「了解 LINE LIFF V2 有哪些功能可以使用吧!」，簡短說明此頻道的用途\n- App types：勾選 `Web app` 即可。目前僅需透過瀏覽器開啟 LIFF 連結,暫不需要原生應用程式\n- Email address：預設為註冊帳號時使用的信箱,用於接收重要通知\n\n> 雖非必填項目,但建議設置頻道圖示,因為使用者在首次授權時會看到此圖示,有助於建立品牌識別度\n\n完成上述設定後,即可建立 LINE Login 頻道。\n\n![LINE Login 頻道創建成功](https:\u002F\u002Fres.cloudinary.com\u002Fdseg0uwc9\u002Fimage\u002Fupload\u002Fv1759757016\u002F2025%20IT%20%E9%90%B5%E4%BA%BA%E8%B3%BD\u002FDay%2023%EF%BC%9ALINE%20LIFF%20%E7%B6%B2%E9%A0%81%E6%87%89%E7%94%A8%E9%96%8B%E7%99%BC%E5%85%A5%E9%96%80\u002FLINE_Login_%E9%A0%BB%E9%81%93%E5%89%B5%E5%BB%BA%E6%88%90%E5%8A%9F_p9gtob.png)\n\n> 頻道下方會顯示發布狀態。當狀態為「Developing」時，僅限開發者本人測試使用，無法分享給其他使用者。若需要讓其他人使用，需將頻道發布為正式版本，狀態會變更為「Published」。\n\n### 創建 Line LIFF 應用程式\n\n> 每個 LINE Login 頻道最多可新增 30 個 LINE LIFF 應用程式\n\n進入剛才建立的 LINE Login 頻道後，點選「LIFF」頁籤，即可進行 LIFF 應用程式的相關設定。\n\n向下捲動頁面，點擊「Add」按鈕，開始新增第一個 LIFF 應用程式。\n\n![LINE LIFF

LIFF 應用程式需填寫以下必要資訊：**\n\n- LIFF app name：填寫「LIFF-Demo-1」，作為應用程式識別名稱\n- Size：compact。決定 LIFF 瀏覽器打開呈現的大小，總共有 `Full`、`Tall`、`Compact` 三種尺寸  \n    ![LINE LIFF 不同尺寸顯示方式](https:\u002F\u002Fres.cloudinary.com\u002Fdseg0uwc9\u002Fimage\u002Fupload\u002Fv1759757560\u002F2025%20IT%20%E9%90%B5%E4%BA%BA%E8%B3%BD\u002FDay%2023%EF%BC%9ALINE%20LIFF%20%E7%B6%B2%E9%A0%81%E6%87%89%E7%94%A8%E9%96%8B%E7%99%BC%E5%85%A5%E9%96%80\u002FLINE_LIFF_%E4%B8%8D%E5%90%8C%E5%B0%BA%E5%AF%B8%E9%A1%AF%E7%A4%BA%E6%96%B9%E5%BC%8F_py7vj8.png)\n- Endpoint URL：：填寫「https:\u002F\u002Fwww.google.com\u002F」 。此欄位為 LIFF 前端專案的伺服器網址。由於目前尚未建立專案,暫時以 Google 首頁作為測試網址。\n- Scope：將 openid、profile 及 chat\\_message.write 三個選項都勾選。這部分在[官網](https:\u002F\u002Fdevelopers.line.biz\u002Fen\u002Fdocs\u002Fliff\u002Fregistering-liff-apps\u002F#registering-liff-app)有詳細說明。\n\n> 不同 Scope 會影響可使用的 LIFF SDK 方法：\n> \n> -   openid：基本的身份驗證權限，可使用 `liff.getIDToken()` 及 `liff.getDecodedIDToken()`\n> -   profile：可使用 `liff.getProfile()` 取得使用者資訊，或使用 `liff.getFriendship()` 確認是否已加入官方帳號為好友\n> -   chat\\_message.write：允許透過 `liff.sendMessages()` 發送訊息到 LINE 聊天室。\n\n- Add friend option：設定為 `Off`。此選項控制使用者在授權時是否需要加入對應的 LINE 官方帳號為好友。\n\n**【 Options 】**\n\n- Scan QR：勾選此選項,允許 LIFF 應用程式使用 `liff.scanCodeV2()` 方法啟動 LINE 內建的 QR code 掃描器。\n\n創建完成後，就能看到 LIFF 應用程式的名稱和相關資訊。記得先記好目前的 LIFF ID 後面會使用到喔。\n\n![LIFF

Login 頻道設定中開啟 email 權限。\n\n![LINE Login 設定(官方帳號 & Email

LIFF URL 請求流程說明\n\n當使用者透過行動裝置開啟 LIFF URL 時，會看到需要授權的畫面。  \n![LIFF

`endpoint URL`，流程就到此結束。由於目前設定的 `endpoint URL` 並非指向使用 LIFF 開發的網站，因此不會執行後續的 LIFF 初始化流程。\n\n* * *\n\n### 使用 Vue 開發 LIFF 應用程式\n\n**Step 1：使用官方腳手架工具創建專案**\n\n開啟終端機，輸入以下指令來創建 LIFF 專案：\n\n```bash\nnpx @line\u002Fcreate-liff-app\n```\n\n**Step 2：選擇開發框架並填入 LIFF ID**\n\n根據互動式問答選擇您要使用的前端框架，並輸入剛才創建的 LIFF 應用程式 ID。\n\n> 本範例使用 Vue 框架進行示範（預設採用 Options API）\n\n![LIFF 腳手架問答創建](https:\u002F\u002Fres.cloudinary.com\u002Fdseg0uwc9\u002Fimage\u002Fupload\u002Fv1759760808\u002F2025%20IT%20%E9%90%B5%E4%BA%BA%E8%B3%BD\u002FDay%2023%EF%BC%9ALINE%20LIFF%20%E7%B6%B2%E9%A0%81%E6%87%89%E7%94%A8%E9%96%8B%E7%99%BC%E5%85%A5%E9%96%80\u002FLIFF_%E8%85%B3%E6%89%8B%E6%9E%B6%E5%95%8F%E7%AD%94%E5%89%B5%E5%BB%BA_p9n0la.png)\n\n**Step 3：查看專案結構並啟動開發伺服器**\n\n創建完成後，可以查看專案的資料夾結構，預設的進入點是 `src\u002FApp.vue`。\n\n> 如果前面步驟沒有設定 LIFF ID，可以在 `.env` 檔案中進行設定。\n\n在專案路徑下輸入以下指令啟動開發伺服器：\n\n```bash\nnpm run dev\n```\n\n開啟架設的伺服器查看 LIFF 專案網頁：\n\n> 這邊可以按照啟動的網址輸入至 URL，查看這個 LIFF 初始專案的網頁\n\n![Vite 開發伺服器](https:\u002F\u002Fres.cloudinary.com\u002Fdseg0uwc9\u002Fimage\u002Fupload\u002Fv1759761136\u002F2025%20IT%20%E9%90%B5%E4%BA%BA%E8%B3%BD\u002FDay%2023%EF%BC%9ALINE%20LIFF%20%E7%B6%B2%E9%A0%81%E6%87%89%E7%94%A8%E9%96%8B%E7%99%BC%E5%85%A5%E9%96%80\u002FVite_%E9%96%8B%E7%99%BC%E4%BC%BA%E6%9C%8D%E5%99%A8_izxhfm.png)\n\n看到網頁這樣呈現就代表 LIFF 初始化成功囉  \n![LIFF 開發伺服器初始化成功顯示畫面](https:\u002F\u002Fres.cloudinary.com\u002Fdseg0uwc9\u002Fimage\u002Fupload\u002Fv1759761198\u002F2025%20IT%20%E9%90%B5%E4%BA%BA%E8%B3%BD\u002FDay%2023%EF%BC%9ALINE%20LIFF%20%E7%B6%B2%E9%A0%81%E6%87%89%E7%94%A8%E9%96%8B%E7%99%BC%E5%85%A5%E9%96%80\u002FLIFF_%E9%96%8B%E7%99%BC%E4%BC%BA%E6%9C%8D%E5%99%A8%E5%88%9D%E5%A7%8B%E5%8C%96%E6%88%90%E5%8A%9F%E9%A1%AF%E7%A4%BA%E7%95%AB%E9%9D%A2_bgsxej.png)\n\nLIFF 應用程式在載入時會自動執行初始化程序。當使用者透過 LINE 應用程式開啟 LIFF URL 時，系統會顯示授權畫面請求使用者同意。授權完成且 LIFF 初始化成功後，應用程式即可正常使用 [LIFF API](https:\u002F\u002Fdevelopers.line.biz\u002Fen\u002Freference\u002Fliff\u002F#get-profile) 提供的各項功能，例如取得使用者資料、傳送訊息等。\n\n> 若使用者透過網頁版(非 LINE 應用程式)開啟 LIFF URL，則需要額外整合 LINE Login 進行身份驗證，才能正常使用 LIFF 功能。\n\n### 使用 ngrok 替換 LIFF Endpoint URL\n\n此設定方式與先前架設 LIFF Webhook Server 的流程相同。在開發初期階段，我們同樣透過 ngrok 第三方服務，將本地的 HTTP 網址轉換為符合 HTTPS 安全協定的網址，以滿足 LINE Platform 的安全性要求。這樣可以優先確保應用程式能夠正常運作，後續再進行正式部署。\n\n在設定 LIFF Endpoint URL 之前，需要在 Vite 配置檔中加入 ngrok 網域的 `allowedHosts` 設定。這是因為 Vite 開發伺服器預設僅接受來自 localhost 的連線請求，必須額外授權才能允許 ngrok 代理服務的外部網域存取。\n\n**Step 1：設定 Vite 允許的主機清單**\n\n在 vite.config.ts 中加入 ngrok 網域設定。\n\n**vite.config.ts**\n\n```ts\nimport { defineConfig } from \"vite\";\nimport vue from \"@vitejs\u002Fplugin-vue\";\n\n\u002F\u002F https:\u002F\u002Fvitejs.dev\u002Fconfig\u002F\nexport default defineConfig({\n  plugins: [vue()],\n  server: {\n    allowedHosts: [\".ngrok-free.app\"], \u002F\u002F 開發階段搭配 ngrok 使用\n  },\n});\n```\n\n**Step 2：實作 LINE Login 驗證機制**\n\n由於我們是透過網頁版開啟 LIFF 應用程式，當需要讀取使用者資料時，必須先經過登入驗證環節。確認使用者身份合法後，才能透過 liff 物件呼叫 getProfile() 方法取得使用者資料。\n\n**本範例使用的 LIFF API：**\n\n- liff.init()：初始化 LIFF 應用程式，需傳入 LIFF ID\n- liff.isLoggedIn()：檢查使用者是否已登入\n- liff.login()：如果用戶未登入，導向 LINE Login 授權頁面\n- liff.getProfile()：取得使用者的個人資料（包含 userId、displayName、pictureUrl 等）\n\n**src\u002FApp.vue**\n\n```ts\n\u002F\u002F 略\n\u003Cscript lang=\"ts\">\nimport { defineComponent } from \"vue\";\nimport liff from \"@line\u002Fliff\";\n\nexport default defineComponent({\n  data() {\n    return {\n      message: \"\",\n      error: \"\"\n    };\n  },\n  mounted() {\n    liff\n      .init({\n        liffId: import.meta.env.VITE_LIFF_ID\n      })\n      .then(async () => {\n        if (!liff.isLoggedIn()) {\n          liff.login(); \u002F\u002F 若未登入則導向登入頁面\n        } else {\n          const userProfile = await liff.getProfile();\n          this.message = JSON.stringify(userProfile);\n        }\n      })\n      .catch((e: Error) => {\n        this.message = \"LIFF init failed.\";\n        this.error = `${e}`;\n      });\n  }\n});\n\u003C\u002Fscript>\n```\n\n接著啟動 ngrok，並將產生的網址替換至 LINE Developers 上的 LIFF Endpoint URL。完成後，即可透過行動裝置或網頁瀏覽器開啟 LIFF URL 進行測試。\n\n![LIFF 伺服器執行 getProfile

liff.getProfile() 可以取得使用者身份資料，但官方文件特別提醒，若直接將前端取得的用戶身份傳送至後端伺服器，會有資料被[竄改的風險](https:\u002F\u002Fdevelopers.line.biz\u002Fen\u002Fdocs\u002Fliff\u002Fusing-user-profile\u002F#sending-id-token)。建議改為透過驗證 ID token 的方式，讓後端安全地取得使用者身份資訊。\n\n到這邊，我們已經成功完成上述流程圖的完整流程：成功初始化 LIFF 應用程式，並正常顯示自己架設的 LIFF 網頁。\n\n**本日範例有改寫成 Composition API 版本，並且搭配顯示 LIFF App 執行環境的狀態。**\n\n![LIFF App

本日結語\n\nLIFF 是與 LINE App 深度整合的前端框架，可讓網頁應用直接透過 LINE 開啟並進行統一驗證，同時能偵測使用者的執行環境與支援功能，使前端能依實際狀況動態呈現內容。今天的重點主要放在初步了解 LIFF 的基本設定。\n",{"title":433,"description":434},{"name":366,"url":367,"day":101},{"loc":432,"images":2295,"lastmod":435},[2296,2297,2298,2299,2300,2301,2302,2303,2304,2305,2306,2307,2308,2309],{"loc":1222},{"loc":1296},{"loc":1339},{"loc":1365},{"loc":1396},{"loc":1481},{"loc":1518},{"loc":1531},{"loc":1547},{"loc":1611},{"loc":1665},{"loc":1674},{"loc":2243},{"loc":2266},"ithome-2025-day-23","2025-10-06-ithome-2025-day-23",[11,360,362,374],"_5jzqNvD-u6T2Z-jKV1N75vYz6_3AGjyeD5gRaugq0U",1792575185144]
