我可以使用内置功能吗?
我的目标是在有一些延迟的情况下回答用户消息 - 1-5 分钟。但在文档中,我看不到任何设置超时的能力。这是我的代码:
app.post('/sms', async (req, res) => {
const twiml = new MessagingResponse();
const msg = req.body.Body;
const toroMsg = await toroProcess(msg);
twiml.message(toroMsg);
res.writeHead(200, {'Content-Type': 'text/xml'});
res.end(twiml.toString());
});
