Question

我在此处使用此示例代码：https://github.com/watson-developer-cloud/botkit-middleware。

我基本上已经设置了twilio，watson与活动工作流程的对话。我的问题是，当发送文本消息到twilio时，twilio向我使用ngrok公开的webhook发送POST请求。但是当我的代码接收到POST请求时，它会被空体接收。没有文字，用户，从，到。管他呢。我使用的是Twilio SMS Bot，而不是Twilio IPM Bot。

HTTP Requests
-------------

POST /sms/receive              200 OK

利用twilio sms代替ipm进行更改。

const configuration = {
  account_sid: process.env.TWILIO_ACCOUNT_SID,
  auth_token: process.env.TWILIO_AUTH_TOKEN,
  twilio_number: process.env.TWILIO_NUMBER
};

const Botkit = require('botkit');

const controller = Botkit.twiliosmsbot(configuration);

var bot = controller.spawn({});

Twilio开发者传道者在这里。

我注意到有问题的服务器only parses incoming requests as JSON。 Twilio sends webhooks in the format application/x-www-form-urlencoded因此您需要告诉bodyParser解析这些类型的请求。

我将以下内容添加到server.js

app.use(bodyParser.urlencoded({ extended: true }));

然后你应该能够阅读Twilio请求的主体。
