Question

我的帖子webhook：

router.post('/webhook', function (req, res) {
          var data = req.body;

      // Make sure this is a page subscription
      if (data.object == 'page') {
        // Iterate

 over each entry

 // There may be multiple if batched
    data.entry.forEach(function(pageEntry) {
      var pageID = pageEntry.id;
      var timeOfEvent = pageEntry.time;
      // Iterate over each messaging event
      pageEntry.messaging.forEach(function(messagingEvent) {
        if (messagingEvent.optin) {
          receivedAuthentication(messagingEvent);
        } else if (messagingEvent.message) {
          receivedMessage(messagingEvent);
        } else if (messagingEvent.delivery) {
          receivedDeliveryConfirmation(messagingEvent);
        } else if (messagingEvent.postback) {
          receivedPostback(messagingEvent);
        } else if (messagingEvent.read) {
          receivedMessageRead(messagingEvent);
        } else if (messagingEvent.account_linking) {
          receivedAccountLink(messagingEvent);
        } else {
          console.log("Webhook received unknown messagingEvent: ", messagingEvent);
        }
      });
    });

    // Assume all went well.
    //
    // You must send back a 200, within 20 seconds, to let us know
    // you've successfully received the callback. Otherwise, the request
    // will time out and we will keep trying to resend.
    res.sendStatus(200);
  }
});

2.my receivedMessage功能：

function receivedMessage(event) {
  var senderID = event.sender.id;
  var recipientID = event.recipient.id;
  var timeOfMessage = event.timestamp;
  var message = event.message;

  console.log("Received message for user %d and page %d at %d with message:", 
    senderID, recipientID, timeOfMessage);
  console.log(JSON.stringify(message));

  var messageId = message.mid;

  var messageText = message.text;
  var messageAttachments = message.attachments;

  if (messageText) {

    // If we receive a text message, check to see if it matches a keyword
    // and send back the example. Otherwise, just echo the text we received.
    switch (messageText) {
      case 'generic':
        sendGenericMessage(senderID);
        break;

      default:
        sendTextMessage(senderID, messageText);
    }
  } else if (messageAttachments) {
    sendTextMessage(senderID, "Message with attachment received");
  }
}

当我使用sendTextMessage运行我的代码时，这是服务器日志，调用callsend api，我认为我的代码失败了：

2017-03-17T10：06：11.296017 + 00:00 app [web.1]：收到用户留言 1367047720019479和第1334554393257327页，电话：1489745171043 消息：2017-03-17T10：06：11.298010 + 00:00 app [web.1]： {＆＃34;中＆＃34;：＆＃34;中期$ cAAS9xUXoM5lhDQCaY1a27tcMAHJS＆＃34;＆＃34;序列＆＃34;：157393，＆＃34;文本＆＃34;：＆＃34;测试消息＆＃34;} 2017-03-17T10：06：11.298044 + 00:00 app [web.1]： {＆＃34;收件人＆＃34; {＆＃34; ID＆＃34;：＆＃34; 1367047720019479＆＃34;}＆＃34;消息＆＃34; {＆＃34;文本＆＃34;：＆＃34;检测消息＆＃34;}} 2017-03-17T10：06：11.298649 + 00:00 app [web.1]：POST / webhook / 200 3.244 ms - 2

现在当我包含sendtext和callSendAPI时：

function sendTextMessage(recipientId, messageText) {
  var messageData = {
    recipient: {
      id: recipientId
    },
    message: {
      text: messageText
    }
  };
console.log(JSON.stringify(messageData));

callSendAPI(messageData);

}


function callSendAPI(messageData) {

 ***console.log("inside the call api");***
request.post({
    uri: 'https://graph.facebook.com/v2.6/me/messages',
    qs: { access_token: access },
    //method: 'POST',
    json: messageData

  }, function (error, response, body) {
    if (!error && response.statusCode == 200) {
      var recipientId = body.recipient_id;
      var messageId = body.message_id;

      console.log("Successfully sent generic message with id %s to recipient %s", 
        messageId, recipientId);
    } else {
      console.error("Unable to send message.");
      console.error(response);
      console.error(error);
    }
  });  
}

这是它给出的输出：
