Django联络表Google Recaptcha装饰器

Question

我卡在某个地方。我需要一点帮助。

我开始学习django。我为用户登录和注册创建reCaptcha装饰器。它的工作非常好。但是我不能在联系页面上使用相同的reCaptcha装饰器吗？当按下“发送邮件”按钮而不单击reCaptcha按钮时，邮件仍然不见了，并继续显示成功页面。...我该如何解决？

我在这个（sendmail）查看页面上使用装饰器；

view.py

from django.core.mail import send_mail, BadHeaderError
from django.http import HttpResponse
from django.shortcuts import render, redirect
from .forms import ContactForm
from blog.recaptcha import check_recaptcha

@check_recaptcha
def emailView(request, check_recaptcha):
    if request.method == 'GET':
        form = ContactForm()
    else:
        form = ContactForm(request.POST)
        if form.is_valid():
            subject = form.cleaned_data['subject']
            from_email = form.cleaned_data['from_email']
            message = form.cleaned_data['message']
            try:
                send_mail(subject, message, from_email, ['hi@mydomain.net'])
            except BadHeaderError:
                return HttpResponse('Invalid header found.')
        return redirect('sendemail:success')
    return render(request, "email.html", {'form': form})



def successView(request):
    return HttpResponse('Success! Thank you for your message.')

recaptcha.py（装饰器）

from functools import wraps

from django.conf import settings
from django.contrib import messages

import requests

def check_recaptcha(view_func):
    @wraps(view_func)
    def _wrapped_view(request, *args, **kwargs):
        request.recaptcha_is_valid = None
        if request.method == 'POST':
            recaptcha_response = request.POST.get('g-recaptcha-response')
            data = {
                'secret': settings.GOOGLE_RECAPTCHA_SECRET_KEY,
                'response': recaptcha_response
            }
            r = requests.post('https://www.google.com/recaptcha/api/siteverify', data=data)
            result = r.json()
            if result['success']:
                request.recaptcha_is_valid = True
            else:
                request.recaptcha_is_valid = False
                messages.error(request, 'Invalid reCAPTCHA. Please try again.')
        return view_func(request, *args, **kwargs)
    return _wrapped_view

email.html

{% extends "layout.html" %}
{% load crispy_forms_tags %}

{% block body %}

<!-- templates/email.html -->
<h4>Contact Form</h4>
    <form method="post">
    {% csrf_token %}
    {{ form|crispy }}
    <div class="g-recaptcha" data-sitekey="6LfkcHg12554353qbkgi-ebcVMhS6e0-XcB0ce"></div>
    <br>
    <button type="submit" class="btn btn-danger">Send</button>

</form>

{% endblock %}

非常感谢您！
