Question

我创建了此VoiceXML代码，要求用户填写一些数据，然后将这些数据存储在数据库中。

当我通过Postman运行代码以模拟请求时，我没有收到任何错误。但是，当我实际运行并调用Python / Django语音应用程序时，一旦我的应用程序到达该部分，我就会收到一个“内部错误”。

VoiceXML输出：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE vxml SYSTEM "http://www.w3.org/TR/voicexml21/vxml.dtd">

            </filled>
        </block>
    </form>
</vxml>

如果需要的话，可以保存输入的代码：

def InputData(request, element_id, session_id):
    input_element = get_object_or_404(InputData_model, pk=element_id)
    voice_service = input_element.service
    session = lookup_or_create_session(voice_service, session_id)


    if request.method == "POST":
        session = get_object_or_404(CallSession, pk=session_id)

        value = 'DTMF_input'

        result = UserInput()

        result.session = session

        result.category = input_element.input_category 

        result.save()

        return redirect(request.POST['redirect'])

    session.record_step(input_element)
    context = input_generate_context(input_element, session)

    context['url'] = request.get_full_path(False)

    return render(request, 'input.xml', context, content_type='text/xml')

如果我希望用户能够通过DTMF填写数字并将该数据存储到我的模型中，我的VoiceXML代码是否正确？还是我错过了一些重要的功能？

Answer 1

要将结果发布回服务器，您需要使用submit元素而不是goto元素。

<submit src="/vxml/InputData/34/8" namelist="DTMF_input" method="post"/>

在VoiceXML specification中查看详细信息。

VoiceXML发出“内部错误”，但未显示明显错误
