為何不把code貼出來？這樣誰能幫你

上面說的真好 (真心覺得xDDD
流程步驟 參考哪裡 到哪裡卡住 要講清楚 ..

各位大大好，感謝兩津勘吉的提醒，我之前是部署在azure上，現在想轉到heroku
爬了一些文終於將下面兩個檔案部署上去了，不過還是沒有反應，
我部署了兩個檔案

一個是LINEBotTiny.php
程式碼如下：
<?php
if (!function_exists('hash_equals')) {
defined('USE_MB_STRING') or define('USE_MB_STRING', function_exists('mb_strlen'));
function hash_equals($knownString, $userString)
{
$strlen = function ($string) {
if (USE_MB_STRING) {
return mb_strlen($string, '8bit');
}
return strlen($string);
};
// Compare string lengths
if (($length = $strlen($knownString)) !== $strlen($userString)) {
return false;
}
$diff = 0;
// Calculate differences
for ($i = 0; $i < $length; $i++) {
$diff |= ord($knownString[$i]) ^ ord($userString[$i]);
}
return $diff === 0;
}
}
class LINEBotTiny
{
public function __construct($channelAccessToken, $channelSecret)
{
$this->channelAccessToken = $channelAccessToken;
$this->channelSecret = $channelSecret;
}
public function parseEvents()
{
if ($_SERVER['REQUEST_METHOD'] !== 'POST') {
http_response_code(405);
error_log("Method not allowed");
exit();
}
$entityBody = file_get_contents('php://input');
if (strlen($entityBody) === 0) {
http_response_code(400);
error_log("Missing request body");
exit();
}
if (!hash_equals($this->sign($entityBody), $_SERVER['HTTP_X_LINE_SIGNATURE'])) {
http_response_code(400);
error_log("Invalid signature value");
exit();
}
$data = json_decode($entityBody, true);
if (!isset($data['events'])) {
http_response_code(400);
error_log("Invalid request body: missing events property");
exit();
}
return $data['events'];
}
public function replyMessage($message)
{
$header = array(
"Content-Type: application/json",
'Authorization: Bearer ' . $this->channelAccessToken,
);
$context = stream_context_create(array(
"http" => array(
"method" => "POST",
"header" => implode("\r\n", $header),
"content" => json_encode($message),
),
));
$response = file_get_contents('https://api.line.me/v2/bot/message/reply', false, $context);
if (strpos($http_response_header[0], '200') === false) {
http_response_code(500);
error_log("Request failed: " . $response);
}
}
private function sign($body)
{
$hash = hash_hmac('sha256', $body, $this->channelSecret, true);
$signature = base64_encode($hash);
return $signature;
}
}


另一個檔案是index.php
程式碼如下：
<?php
require_once('./LINEBotTiny.php');

$channelSecret = "*****************";

$channelAccessToken = "**********************************************";

$googledataspi = "https://spreadsheets.google.com/feeds/list/*************/od6/public/values?alt=json";

$client = new LINEBotTiny($channelAccessToken, $channelSecret);

foreach ($client->parseEvents() as $event) {
switch ($event['type']) {
case 'message':

$message = $event['message'];

$json = file_get_contents($googledataspi);
$data = json_decode($json, true);
$rand = mt_rand(1,1000);

foreach ($data['feed']['entry'] as $item) {

$number = $item['gsx$number']['$t'];

switch ($message['text']) {
case "123":
if (mb_strpos($rand, $number) !== false) {
$text_123 = $item['gsx$event']['$t'];
}
break;
default:
error_log("Unsupporeted message text: " . $message['text']);
break;
}
}
switch ($message['text']) {
case '123':
$client->replyMessage(array(
'replyToken' => $event['replyToken'],
'messages' => array(
array(
'type' => 'text',
'text' => $text_123,
),
),
));
break;
default:
error_log("Unsupporeted message text: " . $message['text']);
break;
}
break;
default:
error_log("Unsupporeted event type: " . $event['type']);
break;
}
};

先說一下抱歉 PHP我不太熟 語法可能無法幫到忙
上Heroku時可以看Log連接
請注意你的Webhook有正常與Line做連接 並且如果有錯誤可以在Heroku看見錯誤行數
如無連接則可能部屬失敗或是webhook尚未連接
Heroku Log位置 : More -> View Logs

有連結到，我有稍微爬了一下文，我是用php5.6寫的，但heroku預設php好像是7.0，我不知道該如何修正讓heroku跑php5.6，懇請高手指導
