大家好～
今天來試著傳送不同類型訊息回覆使用者吧！

以下範例為以如何使用不同的 MessageBuilder 為主，
若對簽名驗證與一些例外處理有興趣，
歡迎參考 Day13 喔～

Text message

範例1：

use LINE\LINEBot\HTTPClient\CurlHTTPClient;
use LINE\LINEBot;
use LINE\LINEBot\MessageBuilder\TextMessageBuilder;

public function reply(Request $request)
{
    $httpClient = new CurlHTTPClient(env('LINE_BOT_CHANNEL_ACCESS_TOKEN'));
    $bot = new LINEBot($httpClient, ['channelSecret' => env('LINE_BOT_CHANNEL_SECRET')]);
    $replyToken = $request['events'][0]['replyToken'];
    $reply = $request['events'][0]['message']['text'];
    $text = new TextMessageBuilder($reply);
    $bot->replyMessage($replyToken, $text);
}

範例2：

use LINE\LINEBot\HTTPClient\CurlHTTPClient;
use LINE\LINEBot;
use LINE\LINEBot\MessageBuilder\TextMessageBuilder;
use LINE\LINEBot\MessageBuilder\Text\EmojiBuilder;
use LINE\LINEBot\MessageBuilder\Text\EmojiTextBuilder;

public function reply(Request $request)
{
    $httpClient = new CurlHTTPClient(env('LINE_BOT_CHANNEL_ACCESS_TOKEN'));
    $bot = new LINEBot($httpClient, ['channelSecret' => env('LINE_BOT_CHANNEL_SECRET')]);
    $replyToken = $request['events'][0]['replyToken'];
    $reply = $request['events'][0]['message']['text'];
    $emoji1 = new EmojiBuilder(0, '5ac1de17040ab15980c9b438', '095');
    $emoji2 = new EmojiBuilder(1, '5ac1de17040ab15980c9b438', '095');
    $emojiText = new EmojiTextBuilder('$$' . $reply, $emoji1, $emoji2);
    $text = new TextMessageBuilder($emojiText);
    $bot->replyMessage($replyToken, $text);
}

一般文字回覆的使用方式十分容易，
只需將要回覆的 string 放入 TextMessageBuilder 實例中即可。
若想要用 Line Emoji 回覆，
則需要實例化較多個 Class，
還需要知道一些小重點：

1. 最多可用20個 Line Emoji。
2. Line Emoji 使用 $ 作為佔位符。
3. 關於佔位符的 index 計算：
   • 第一個字元位置是以0開始計算。
   • 若 index 位置與 $ 不匹配，會回傳 HTTP 400 Bad request。
4. 可用的 Line Emoji 可以參考官方文件喔。

• EmojiBuilder
  • 
  • $productId 與 $emojiId 請參考官方文件。
  • 
• EmojiTextBuilder
  • 
  • 如果有多個 Line Emoji，就像範例一樣直接依序放入就行了。
    • $emojiText = new EmojiTextBuilder('$$' . $reply, $emoji1, $emoji2);
• TextMessageBuilder
  • 如果是一般文字訊息：
    • 直接將 String 帶入就可以了。
  • 如果是包含 Line Emoji：
    • 將 EmojiTextBuilder 的實例帶入。

Sticker message

use LINE\LINEBot\HTTPClient\CurlHTTPClient;
use LINE\LINEBot;
use LINE\LINEBot\MessageBuilder\StickerMessageBuilder;

public function reply(Request $request)
{
    $httpClient = new CurlHTTPClient(env('LINE_BOT_CHANNEL_ACCESS_TOKEN'));
    $bot = new LINEBot($httpClient, ['channelSecret' => env('LINE_BOT_CHANNEL_SECRET')]);
    $replyToken = $request['events'][0]['replyToken'];
    $sticker = new StickerMessageBuilder('11537', '52002771');
    $bot->replyMessage($replyToken, $sticker);
}

• 可用貼圖請參考官方文件。

Image message

use LINE\LINEBot\HTTPClient\CurlHTTPClient;
use LINE\LINEBot;
use LINE\LINEBot\MessageBuilder\ImageMessageBuilder;

public function reply(Request $request)
{
    $httpClient = new CurlHTTPClient(env('LINE_BOT_CHANNEL_ACCESS_TOKEN'));
    $bot = new LINEBot($httpClient, ['channelSecret' => env('LINE_BOT_CHANNEL_SECRET')]);
    $replyToken = $request['events'][0]['replyToken'];
    $image = new ImageMessageBuilder(
        'https://cdn-icons-png.flaticon.com/512/3522/3522266.png',
        'https://cdn-icons-png.flaticon.com/512/3522/3522248.png'
    );
    $bot->replyMessage($replyToken, $image);
}

上面範例刻意用兩張不一樣的圖片讓測試結果更好分辨：

• 
• 圖Ａ為 Preview Image
  • Max file size: 1 MB
• 圖Ｂ為 Original Content
  • Max file size: 10 MB
• 圖片格式僅接受 JPEG or PNG

Video message

use LINE\LINEBot\HTTPClient\CurlHTTPClient;
use LINE\LINEBot;
use LINE\LINEBot\MessageBuilder\VideoMessageBuilder;

public function reply(Request $request)
{
    $httpClient = new CurlHTTPClient(env('LINE_BOT_CHANNEL_ACCESS_TOKEN'));
    $bot = new LINEBot($httpClient, ['channelSecret' => env('LINE_BOT_CHANNEL_SECRET')]);
    $replyToken = $request['events'][0]['replyToken'];
    $video = new VideoMessageBuilder(
        'https://img-9gag-fun.9cache.com/photo/aEpr2ON_460svvp9.mp4',
        'https://img-9gag-fun.9cache.com/photo/abVPMOL_460swp.png'
    );
    $bot->replyMessage($replyToken, $video);
}

• 
• Preview Image
  • Max file size: 1 MB
  • JPEG or PNG
• Original Content
  • Max file size: 200 MB
  • mp4

Audio message

use LINE\LINEBot\HTTPClient\CurlHTTPClient;
use LINE\LINEBot;
use LINE\LINEBot\MessageBuilder\AudioMessageBuilder;

public function reply(Request $request)
{
    $httpClient = new CurlHTTPClient(env('LINE_BOT_CHANNEL_ACCESS_TOKEN'));
    $bot = new LINEBot($httpClient, ['channelSecret' => env('LINE_BOT_CHANNEL_SECRET')]);
    $replyToken = $request['events'][0]['replyToken'];
    $audio = new AudioMessageBuilder(
        'https://example.com/original.m4a',
        '75000'
    );
    $bot->replyMessage($replyToken, $audio);
}

• 
• Original Content
  • Max file size: 200 MB
  • 格式僅接受 m4a
• Duration
  • Audio file 的時間長度
  • 單位為毫秒

Location message

use LINE\LINEBot\HTTPClient\CurlHTTPClient;
use LINE\LINEBot;
use LINE\LINEBot\MessageBuilder\LocationMessageBuilder;

public function reply(Request $request)
{
    $httpClient = new CurlHTTPClient(env('LINE_BOT_CHANNEL_ACCESS_TOKEN'));
    $bot = new LINEBot($httpClient, ['channelSecret' => env('LINE_BOT_CHANNEL_SECRET')]);
    $replyToken = $request['events'][0]['replyToken'];
    $location = new LocationMessageBuilder(
        '好想工作室',
        '台南市東區北門路二段16號 L2A',
        '22.999739302983308',
        '120.21290532894172'
    );
    $bot->replyMessage($replyToken, $location);
}

電腦版畫面：

手機版畫面：

• 
• Title
  • 自定義的標題
  • Max character limit: 100
• Address
  • 自定義的地址說明
  • Max character limit: 100
• Latitude
  • 緯度
  • Decimal
• Longitude
  • 經度
  • Decimal

Title 與 Address 輸入的值不會影響地圖圖釘的位置，
地圖圖釘的位置是以經緯度為主。
另外 Location message 在電腦與手機上呈現的結果會不一樣喔～

MultiMessageBuilder

use LINE\LINEBot\HTTPClient\CurlHTTPClient;
use LINE\LINEBot;
use LINE\LINEBot\MessageBuilder\MultiMessageBuilder;
use LINE\LINEBot\MessageBuilder\VideoMessageBuilder;
use LINE\LINEBot\MessageBuilder\LocationMessageBuilder;

public function reply(Request $request)
{
    $httpClient = new CurlHTTPClient(env('LINE_BOT_CHANNEL_ACCESS_TOKEN'));
    $bot = new LINEBot($httpClient, ['channelSecret' => env('LINE_BOT_CHANNEL_SECRET')]);
    $replyToken = $request['events'][0]['replyToken'];

    $multiMessageBuilder = new MultiMessageBuilder();

    $video = new VideoMessageBuilder(
        'https://img-9gag-fun.9cache.com/photo/aEpr2ON_460svvp9.mp4',
        'https://img-9gag-fun.9cache.com/photo/abVPMOL_460swp.png'
    );
    $multiMessageBuilder->add($video);

    $location = new LocationMessageBuilder(
        '好想工作室',
        '台南市東區北門路二段16號 L2A',
        '22.999739302983308',
        '120.21290532894172'
    );
    $multiMessageBuilder->add($location);

    $response = $bot->replyMessage($replyToken, $multiMessageBuilder);
}

使用 MultiMessageBuilder 就可以不只回傳一筆訊息喔（最多五筆）。

今天就先這樣啦～
Imagemap message、Template message、Flex Message 就明天再來認識吧！
大家明天見！
若文章有任何問題，
還請大家不吝賜教！
