Question

我正在为facebook Messenger开发机器人。我在php中创建了一个测试页面，一个facebook应用程序和WebHook页面。

我将机器人注册到测试页面并且结果是肯定的，但如果我尝试向页面发送消息，则不响应，好像无法联系页面。

这是我的php脚本：

$access_token = "EAAY...ZD";
$verify_token = "verifica_token";
$hub_verify_token = null;

if(isset($_REQUEST['hub_challenge'])) {
    $challenge = $_REQUEST['hub_challenge'];
    $hub_verify_token = $_REQUEST['hub_verify_token'];
}


if ($hub_verify_token === $verify_token) {
    echo $challenge;
}


// handle bot's anwser
$input = json_decode(file_get_contents('php://input'), true);
$senderId = $input['entry'][0]['messaging'][0]['sender']['id'];
$messageText = $input['entry'][0]['messaging'][0]['message']['text'];
$answer = "I don't understand. Ask me 'hi'.";
if($messageText == "hi") {
    $answer = "Hello";
}
$response = [
    'recipient' => [ 'id' => $senderId ],
    'message' => [ 'text' => $answer ]
];
$ch = curl_init('https://graph.facebook.com/v2.6/me/messages?access_token='.$access_token);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($response));
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
curl_exec($ch);
curl_close($ch);

在将它们组合在一起之前，请单独尝试以下代码。

<?php

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://graph.facebook.com/v2.6/me/messages?access_token=EAAY...ZD",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "{\n    recipient: {id:".$senderId."},\n    message: {text: \"".$answer."\"}\n}",
  CURLOPT_HTTPHEADER => array(
    "cache-control: no-cache",
    "content-type: application/json"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}
