python - 错误 : didn't return an HttpResponse object. 它返回 None

Question

我想按 html 模板中的按钮

              <form action="{% url 'speech2text' %}" class="card-text" method="POST">
                  {% csrf_token %}
                  <button class="btn btn-primary btn-sm" type="submit">Start</button>
              </form>

              <p> Sie haben das folgende gesagt: </p>
              <p> {{ speech_text }} </p>

按下按钮，将执行以下 View 中的代码并将结果发送回模板:

def speech2textView(request):
    if request.method == "POST":
        r = sr.Recognizer()
        with sr.Microphone() as source:
            audio = r.listen(source)
            text = r.recognize_google(audio, language="de-DE")
            args = {'speech_text': text}
            return render(request, 'speech2text.html', args)

这里出了什么问题？非常感谢您的帮助。

我再次编辑了代码，现在它可以工作了。我想分享这个。非常感谢这个社区。

def speech2textView(request):
    args = {}
    if request.method == "POST":
        print(request.method)
        r = sr.Recognizer()
        with sr.Microphone() as source:
            audio = r.listen(source)
            text = r.recognize_google(audio, language="de-DE")
            args = {'speech_text': text}
    return render(request, 'speech2text.html', args)
