今天要把前幾天講過的 HTML、CSS、JavaScript 架構全部整合起來，加上我自己用 FLEX MESSAGE SIMULATOR 拉的三個圖文訊息版面的 JSON 程式碼製作一個完整的 LINE 整人傳訊息網站。

網站架構


⬆ 我在網站建立了三個按鈕，分別對應：假禮物、假爬梯子、假轉帳通知，按下對應的按鈕選擇要傳送的對象擊可傳送訊息，三種整人一次滿足。HTML 建立按鈕及網頁架構程式碼如下：

<!DOCTYPE html>
<html>
<head>
	<meta charset="UTF-8">
	<meta name="viewport"
		content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=0,viewport-fit=cover">
	<title>My LIFF App3</title>
	<style>
		button {
			display: none;
			width: 50%;
			height: 10%;
			padding: 16px 0;
			margin: auto 0;
		}
	</style>
</head>
<body>
	<button id="btnShare" onclick="sendShare_Gift()" style="display: none;margin: 20px auto;padding: 20px;">Gift</button>
	<button id="btnShare2" onclick="sendShare_Ladder()" style="display: none;margin: 20px auto;padding: 20px;">Ladder</button>
	<button id="btnShare3" onclick="sendShare_Pay()" style="display: none;margin: 20px auto;padding: 20px;">Pay</button>
	<button id="btnLogin" onclick="liff.login()" style="display: none;margin: 20px auto;padding: 20px;">Log In</button>
	<button id="btnLogOut" onclick="logOut()" style="display: none;margin: 20px auto;padding: 20px;">Log Out</button>
	<script src="https://static.line-scdn.net/liff/edge/2/sdk.js"></script>
</body>
</html>

⬆ 記得要嵌入 LINE SDK
接下來要進到用　JavaScript 串 LINE API 的部分，首先要使用 LIFF API 時需要先初始化 LIFF ID 再登入(外部瀏覽器才需要寫 LINE Login，使用 LINE LIFF 開啟型式不需要再寫 LINE Login 函式)
使用 async await 建立一個 main() 主程式，用來初始化 LINE LIFF ID 後登入 LINE 再列出三個按鈕：

async function main() {
			await liff.init({ liffId: "1656997750-QLPwGlaN" })
			if (liff.isLoggedIn()) {
				document.getElementById("btnShare").style.display = "block"
				document.getElementById("btnShare2").style.display = "block"
				document.getElementById("btnShare3").style.display = "block"
				if (!liff.isInClient()) {
					document.getElementById("btnLogOut").style.display = "block"
				}
			} else {
				document.getElementById("btnLogin").style.display = "block"
			}
		}

再分別建立三個　async await 函式：sendShare_Pay()、sendShare_Ladder()、sendShare_Gift()，用來取得登入者的暱稱和傳送假圖文訊息。取得登入者程式碼如下:

name = await liff.getProfile().then((profile) => {
				return profile.displayName;
			}).catch((err) => {
				return err;
			});

之後再用 shareTargetPicker() 函式修改 type 參數為 "flex"，代表傳送圖文訊息給指定的聊天室。最後將 contents 參數內放入該圖文訊息的 JSON 程式碼：

⬆ 把紅框裡面全部的程式碼放到　contents　裡面，就可以傳送預覽的圖文訊息。
