当 twilio 收到短信时，我的代码返回 http 415 响应

Question

I've configured a webhook in Twilio to point to the below controller when someone sends an sms to my Twilio phone number. But, when an sms is sent, Twilio pops up a 11200 error and ngrok is telling me I'm returning an HTTP 415 error. Any ideas what I'm doing wrong? Here is the controller:

    [HttpPost]
    public IActionResult Index(SmsRequest incomingMessage)
    {
        var messagingResponse = new MessagingResponse();
        messagingResponse.Message(_incomingSMSService.parseIncomingMessage(incomingMessage.From, incomingMessage.Body));

        return TwiML(messagingResponse);
    }

Answer 1

The SmsRequest is coming from the form data, so the controller should have [FormData]SmsRequest incomingMessage in it like this:

    [HttpPost]
    public IActionResult Index([FormData]SmsRequest incomingMessage)
    {
        var messagingResponse = new MessagingResponse();
        messagingResponse.Message(_incomingSMSService.parseIncomingMessage(incomingMessage.From, incomingMessage.Body));

        return TwiML(messagingResponse);
    }
