【中文标题】使用 facebook messenger bot 示例教程代码时，我收到消息：\'(#100) No matching user found\'【英文标题】：I am getting message: '(#100) No matching user found', when using the facebook messenger bot sample tutorial code使用 facebook messenger bot 示例教程代码时，我收到消息：'(#100) No matching user found' 【发布时间】：2016-11-10 08:32:49 【问题描述】：使用相同的 Facebook 入门指南 (https://developers.facebook.com/docs/messenger-platform/quickstart)
在输入消息并将其发送到机器人时，我在 node.js 控制台上遇到错误。
error:
message: '(#100) No matching user found',
type: 'OAuthException',
code: 100,
fbtrace_id: 'BLguK1o+VsH'
我有最新版本的 node.js 并且正在使用 Ngrok 来公开我的本地主机。
我的 app.post 例程如下：（它是入门指南的精确副本）
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
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.
// res.sendStatus(200);
);
这里是被调用的 receivedMessage 函数
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;
// You may get a text or attachment but not both
var messageText = message.text;
var messageAttachments = message.attachments;
if (messageText)
// If we receive a text message, check to see if it matches any special
// keywords and send back the corresponding example. Otherwise, just echo
// the text we received.
switch (messageText)
case 'image':
sendImageMessage(senderID);
break;
case 'button':
sendButtonMessage(senderID);
break;
case 'generic':
sendGenericMessage(senderID);
break;
case 'receipt':
sendReceiptMessage(senderID);
break;
default:
//getArticles(function(err,articles)
// sendTextMessage(senderID, articles[0].text);
//);
sendTextMessage(senderID, messageText);
/* client.converse('my-user-session-42', messageText, )
.then((data) =>
console.log('the question asked :' + messageText);
sendTextMessage(senderID, data.msg);
console.log('Yay, got Wit.ai response: ' + JSON.stringify(data));
).catch(console.error);
*/
else if (messageAttachments)
sendTextMessage(senderID, "Message with attachment received");
更多这里是我的要求声明：
const bodyParser = require('body-parser');
var express = require('express');
var request = require('request');
var router = express.Router();
const fetch = require('node-fetch');
const Wit, log = require('node-wit');
以下是使用的其余函数：
function sendTextMessage(recipientId, messageText)
var messageData =
recipient:
id: recipientId
,
message:
text: messageText
;
callSendAPI(messageData);
function callSendAPI(messageData)
request(
uri: 'https://graph.facebook.com/v2.6/me/messages',
qs: access_token: PAGE_ACCESS_TOKEN ,
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);
);
所以我在某处读到这一切都与页面 ID 或 facebook 处理整数的方式有关，但我有点困惑。
任何帮助将不胜感激。
【问题讨论】：
我收到了同样的错误信息，几天前这里的一切都正常了。也找不到任何有关重大更改的消息。太不稳定了。 实在是太郁闷了，官方教程代码好像下不了，想看懂继续工作 突然那些奇怪的错误消失了，我能够再次成功发送/接收消息。你有同样的经历吗？ 有时它可以工作，但现在我不断收到我输入的消息的回声。似乎在某个地方我可以找到一个循环。 我今天早些时候有同样的经历，并发现这是由于 Facebook Messenger 机器人的新回显功能导致它循环然后抛出如上所述的错误（因为它最终尝试发送到页面id 而不是用户 id）。我的解决办法是检查message.is_echo。如果为真，请记录它并且不执行任何进一步的操作。发生这种情况是因为 Facebook 将回声视为消息，即除了 is_echo 字段外，它们在任何地方都没有标志（请参阅：developers.facebook.com/docs/messenger-platform/…）
【参考方案1】：
出现此错误是因为使用了不正确的令牌将消息发送回机器人。确保你有正确的（即使一开始是硬编码），可以从你的 developers.facebook.com 页面的 Messenger -> Settings -> Token Generation 下复制。
【讨论】：
令牌偶尔会改变。在应用程序设置中，我们必须选择关联的 FB 页面并生成令牌。之后，我们必须像这样重新订阅应用程序：developers.facebook.com/docs/messenger-platform/…【参考方案2】：你只需要绕过你自己的消息。
您的 Bot 具有唯一 ID（不是 App ID），因此您可以在 POST 逻辑中尝试此解决方法：
var myID = '...' ;
.....
event = req.body.entry[0].messaging[i];
sender = event.sender.id;
if (event.message && event.message.text && sender != myID)
.....
您可以通过查看您的消息来获取您的 Bot id：
"sender":
"id":"USER_ID"
,
Message Received reference
JSON 示例：
even.message:
"sender":"id":"**yourBotID**",
"recipient":"id":"**clientID**",
"timestamp":1468241667962,
"message": "**is_echo":true**,
"app_id":**appID**,
"mid":"mid....",
"seq":617,"text":"..."
提示：要识别您的 BotID，只需在消息负载中查找 "message": "is_echo": true,..。
问候
【讨论】：
嗨，谢谢，我对 node.js 和机器人还很陌生，所以我不太明白 myId 是什么。 我得到这样的发件人ID - function receivedMessage(event) var senderID = event.sender.id.toString(); ..... 您的解决方案会修复以下消息：'(#100) No matching user found'，问题吗？ 是的，当然。我为我自己的机器人 @myRolloBot facebook.com/Myrollobot 编写了这个解决方法 对不起，我对此有点陌生，你能告诉我如何获得 myID 吗？我知道 sender.id 来自哪里。【参考方案3】：我去了 Facebook Messenger 设置 -> Webhooks -> 编辑事件并从订阅的事件中删除了 messenger_echoes。这解决了问题。
【讨论】：
完全有效！希望我能多次投票【参考方案4】：我遵循了这个指南http://x-team.com/2016/04/how-to-get-started-with-facebook-messenger-bots/
一切都奏效了：
我在下面发布了我的代码：

var app = express();
const fetch = require('node-fetch');
const Wit, log = require('node-wit');
app.use(bodyParser.urlencoded(extended: false))
var PAGE_ACCESS_TOKEN = '********'
var MY_TOKEN = '********';
// Wit.ai code
const client = new Wit(accessToken: '*********');
// GET home page.
app.get('/', function(req, res, next)
res.render('index', title: 'Express' );
);
app.get('/webhook/', function(req, res)
if (req.query['hub.mode'] === 'subscribe' &&
req.query['hub.verify_token'] === 'hello_token_success')
console.log("Validating webhook");
res.status(200).send(req.query['hub.challenge']);
else
console.error("Failed validation. Make sure the validation tokens match.");
res.sendStatus(403);
);
//** Receive Messages **
app.post('/webhook/', function (req, res)
var data = req.body;
var events = req.body.entry[0].messaging;
for (var i = 0; i < events.length ; i++)
var event = events[i];

var text = event.message.text;
sendTextMessage(event.sender.id, "Text received, echo: "+ text.substring(0, 200));
// Assume all went well.

【讨论】：
您在github.com/Microsoft/BotBuilder/issues/2274之前是否完成了帐号关联【参考方案5】：确保您使用了正确的收件人 ID。 Recipient 不是页面或应用 ID，而是（如果您想向用户发送消息）用户的 ID。
您可以配置https://requestb.in等webhook并检查来自messanger的请求，您要查找的ID是：
"sender":"id":"1499894473423552"
【讨论】：
【参考方案6】：我删除了事件中的消息回显，只选择了消息和回发，它解决了问题
