验证码验证Python Django

我收到以下设置的无效验证码响应。联系人表单工作得非常好，我添加了验证验证码的规则，我检查了密钥，即使解决了它，仍然得到无效的验证码。以下是我的设置：

views.py

    def get_client_ip(request):
    x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
    if x_forwarded_for:
        ip = x_forwarded_for.split(',')[0]
    else:
        ip = request.META.get('REMOTE_ADDR')
    return ip

def grecaptcha_verify(request):
        response = {}
        data = request.POST
        captcha_rs = data.get('g-recaptcha-response')
        url = "https://www.google.com/recaptcha/api/siteverify"
        params = {
            'secret': settings.RECAPTCHA_SECRET_KEY,
            'response': captcha_rs,
            'remoteip': get_client_ip(request)
        }
        verify_rs = requests.get(url, params=params, verify=True)
        verify_rs = verify_rs.json()
        response["status"] = verify_rs.get("success", False)
        response['message'] = verify_rs.get('error-codes', None) or "Unspecified error."
        return response

def contact(request):
        if request.method == 'POST':
            if grecaptcha_verify(request) == "success":
                subject = request.POST.get('subject')
                message = request.POST.get('message')
                email = request.POST.get('email')     
                if subject and message and email:
                    try:
                        send_mail(subject, message, email, ['myemail@gmail.com'],fail_silently= True)
                    except BadHeaderError:
                        return HttpResponse('{Bad Header}')
                    return greatsuccess(request)        
                else:
                    return HttpResponse('{Invalid Form}')
            else:
                return HttpResponse('Invalid Captcha')    
        return render(request, 'personal/contact.html')

我的模板：

        <form role="form" method="POST">

我对Python非常陌生，如何检查后台发生的事情以及验证在哪一点失败？

您正在发出

get

验证请求，但需要向其发出

post

请求。这就是验证码验证失败的原因。所以试着这样做：

    url = "https://www.google.com/recaptcha/api/siteverify"
    headers = {'User-Agent': 'DebuguearApi-Browser',}
    params = {'secret': settings.RECAPTCHA_SECRET_KEY, 'response': captcha_rs}
    verify_rs = requests.post(url, data=params, headers=headers)  # <--  Update Here
    ... # rest of your code

url=”https://www.google.com/recaptcha/api/siteverify"
headers={'User-Agent'：'DebuguearApi浏览器'，}
params={'secret'：settings.repactcha_secret_KEY，'response'：captcha_rs}
验证_rs=requests.post（url，data=params，headers=headers）#Ok。
我让它工作了。谢谢鲁德拉的帮助

我先删除了
，因为我注意到这是不必要的。这允许在POST数据中包含g-recaptcha-response。显然，重要的是要确保你的表单是正确的，并且谷歌喜欢它

其次，我根据收到的建议对main views.py做了一些修改+一些改进

def greatsuccess(request):
    messages.success(request, "Email sent!")
    return render(request, 'personal/contact.html')

def greatfail(request):
    messages.error(request, "Invalid Captcha!")
    return render(request, 'personal/contact.html')

def grecaptcha_verify(request):
        data = request.POST
        captcha_rs = data.get('g-recaptcha-response')
        url = "https://www.google.com/recaptcha/api/siteverify"
        headers = {'User-Agent': 'DebuguearApi-Browser',}
        params = {'secret': settings.RECAPTCHA_SECRET_KEY, 'response': captcha_rs}
        verify_rs = requests.post(url,params, headers=headers)
        verify_rs = verify_rs.json()
        response = verify_rs.get("success", False)
        return response 

def contact(request):
    if request.method == 'POST':
        response=grecaptcha_verify(request)
        if response == True :
            subject = request.POST.get('subject')
            message = request.POST.get('message')
            email = request.POST.get('email')     
            if subject and message and email:
                try:
                        send_mail('Sent from mywebsite '+subject, message, email, ['email@gmail.com'],fail_silently= True)
                except BadHeaderError:
                    return HttpResponse('{Bad Header}')
                return greatsuccess(request)        
            else:
                    return HttpResponse('{Invalid Form}')
        else:
            greatfail(request)
    return render(request, 'personal/contact.html')

嗨，谢谢你的提示。我改变了这一点，我也改变了一点代码，这样它就可以吐出谷歌的回应。我得到“缺少输入响应”。我似乎无法确定它发生在哪一点。消息与响应相同。根据文档，请求的格式似乎不正确。您能否检查验证码是否得到正确的值。另外，我已经稍微更新了我的答案，请检查它是否有效。嗨，谢谢你的帮助。我不知道如何查看验证码是否有正确的值。我没有在Eclipse控制台中看到它。我该怎么做？只需使用
print（验证码）
