我正在开发一个facebook聊天机器人 . 我面临一个我无法解决的问题 . 我正在用laravel开发它 . 在这里,我无法获得回发有效负载 . 这是我的代码
public function index(Request $request) {
if ($request->hub_verify_token === $this->verifyToken) {
echo $request->hub_challenge;
exit;
}
$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'];
$pageId = $input['entry'][0]['id'];
$accessToken = "access_token_that_got_from_fb";
//set Message
if($messageText != "") {
$answer = "Howdy! User";
}
if($messageText == "hello") {
$answer = 'Testing hello from bot';
}
foreach ($input['entry'][0]['messaging'] as $message) {
// When bot receive message from user
if (!empty($message['postback'])) {
$answer = 'got it tada';
}
}
//send message to facebook bot
$response = [
'recipient' => [ 'id' => $senderId ],
'message' => [ 'text' => $answer ] //json_encode($request->getContent())
];
$ch = curl_init('https://graph.facebook.com/v2.11/me/messages?access_token='.$accessToken);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($response));
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
$result = curl_exec($ch);
curl_close($ch);
}
我的路线是
Route::any('chatbot', 'ChatbotController@index');
这里的消息正在发挥作用 . 但是回发有效负载请求不会转到服务器 . 另一方面,在普通的php文件中使用相同的代码,我能够获得回发paylod .
$hubVerifyToken = 'chatbot';
$accessToken = "access_token";
// check token at setup
if ($_REQUEST['hub_verify_token'] === $hubVerifyToken) {
echo $_REQUEST['hub_challenge'];
exit;
}
// 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'];
$postback = isset($input['entry'][0]['messaging'][0]['postback']['payload']) ? $input['entry'][0]['messaging'][0]['postback']['payload'] : '' ;
//set Message
if($messageText == "hi") {
$answer = "Hello";
}
if($messageText == "hello") {
$answer = "Hello there, welcome to Chatleads";
}
if($postback) {
$answer = "postback TADA";
}
//send message to facebook bot
$response = [
'recipient' => [ 'id' => $senderId ],
'message' => [ 'text' => $answer ]
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://graph.facebook.com/v2.11/me/messages?access_token=$accessToken");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($response));
curl_setopt($ch, CURLOPT_POST, 1);
$headers = array();
$headers[] = "Content-Type: application/json";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
curl_close ($ch);
如何解决这个问题?有人能告诉我一条路吗?

通过检查laravel.log文件解决了这个问题 .
messageText应该是这样的 . 这就是它导致错误的原因 .
