Python 向我的Django登录页面添加Recaptcha表单

我想将Recaptcha添加到我的登录表单中。我正在跟踪存储库，但遇到了一些问题：我将此添加到了我的

视图.py

：

from django import forms
from captcha.fields import ReCaptchaField

class FormWithCaptcha(forms.Form):
    captcha = ReCaptchaField()

from django.shortcuts import render, redirect
from django.http import HttpResponse
from .models import Tutorial
from django.contrib.auth.forms import AuthenticationForm
from django.contrib.auth import login, logout, authenticate
from django.contrib import messages
from .forms import NewUserForm

from django import forms
from captcha.fields import ReCaptchaField

class FormWithCaptcha(forms.Form):
    captcha = ReCaptchaField()

def homepage(request):
    return render(request=request,
                  template_name="main/home.html",
                  context={"tutorials": Tutorial.objects.all})

def register(request):
    if request.method == "POST":
        form = NewUserForm(request.POST)
        if form.is_valid():
            user = form.save()
            username = form.cleaned_data.get('username')
            messages.success(request, f"New Account Created: {username}")
            login(request, user)
            messages.info(request, f"You are now logged in as {username}")
            return redirect("main:homepage")
        else:
            for msg in form.error_messages:
                messages.error(request, f"{msg}: {form.error_messages[msg]}")


    form = NewUserForm
    return render(request,
                  "main/register.html",
                  context={"form":form})

def logout_request(request):
    logout(request)
    messages.info(request, "Logged out successfully!")
    return redirect("main:homepage")

def login_request(request):
    if request.method == "POST":
        form = AuthenticationForm(request, data=request.POST)
        if form.is_valid():
            username = form.cleaned_data.get('username')
            password = form.cleaned_data.get('password')
            user = authenticate(username=username, password=password)
            if user is not None:
                login(request, user)
                messages.info(request, f"You are now logged in as {username}")
                return redirect("main:homepage")
            else:
                messages.error(request, "Invalid username or password")

        else:
            messages.error(request, "Invalid username or password")

    form = AuthenticationForm()
    return render(request,
                  "main/login.html",
                  {"form":form})

但我真的不知道该怎么办。我想我需要在我的

login.html

页面中添加一些东西，但我不知道是什么。谁能给我一些帮助吗？请注意，我已经将公钥和私钥添加到我的

settings.py

文件中

这是整个

视图.py

：

from django import forms
from captcha.fields import ReCaptchaField

class FormWithCaptcha(forms.Form):
    captcha = ReCaptchaField()

from django.shortcuts import render, redirect
from django.http import HttpResponse
from .models import Tutorial
from django.contrib.auth.forms import AuthenticationForm
from django.contrib.auth import login, logout, authenticate
from django.contrib import messages
from .forms import NewUserForm

from django import forms
from captcha.fields import ReCaptchaField

class FormWithCaptcha(forms.Form):
    captcha = ReCaptchaField()

def homepage(request):
    return render(request=request,
                  template_name="main/home.html",
                  context={"tutorials": Tutorial.objects.all})

def register(request):
    if request.method == "POST":
        form = NewUserForm(request.POST)
        if form.is_valid():
            user = form.save()
            username = form.cleaned_data.get('username')
            messages.success(request, f"New Account Created: {username}")
            login(request, user)
            messages.info(request, f"You are now logged in as {username}")
            return redirect("main:homepage")
        else:
            for msg in form.error_messages:
                messages.error(request, f"{msg}: {form.error_messages[msg]}")


    form = NewUserForm
    return render(request,
                  "main/register.html",
                  context={"form":form})

def logout_request(request):
    logout(request)
    messages.info(request, "Logged out successfully!")
    return redirect("main:homepage")

def login_request(request):
    if request.method == "POST":
        form = AuthenticationForm(request, data=request.POST)
        if form.is_valid():
            username = form.cleaned_data.get('username')
            password = form.cleaned_data.get('password')
            user = authenticate(username=username, password=password)
            if user is not None:
                login(request, user)
                messages.info(request, f"You are now logged in as {username}")
                return redirect("main:homepage")
            else:
                messages.error(request, "Invalid username or password")

        else:
            messages.error(request, "Invalid username or password")

    form = AuthenticationForm()
    return render(request,
                  "main/login.html",
                  {"form":form})

您应该发布您的

views.py

，这样我可以更好地帮助您，但是使用Django的常识，您应该使用FormWithCaptcha作为上下文变量呈现

login.html

文件，例如，命名为recaptcha，然后在您的登录文件中，在需要的任何地方像{recaptcha}一样调用它。但是，如果您的问题尚未解决，请再次发布您的视图文件

def login_request(request):
    if request.method == "POST":
        form = AuthenticationForm(request, data=request.POST)
        if form.is_valid():
            username = form.cleaned_data.get('username')
            password = form.cleaned_data.get('password')
            user = authenticate(username=username, password=password)
            if user is not None:
                login(request, user)
                messages.info(request, f"You are now logged in as {username}")
                return redirect("main:homepage")
            else:
                messages.error(request, "Invalid username or password")

        else:
            messages.error(request, "Invalid username or password")

    form = AuthenticationForm()
    recaptcha = FormWithCaptcha()
    return render(request,
                  "main/login.html",
                  {"form":form, "recaptcha": recaptcha})

通过从django.contrib.auth子类化LoginForm，您可以在没有外部LIB的情况下实现目标

有关代码示例和更详细的解释，请参见答案。使用上下文处理器，您还可以将recaptcha公钥添加到login.html模板中。

I added views.py！我觉得您需要构建自己的自定义身份验证表单（但因为我不知道库），您应该将captcha表单添加到渲染中，我将更新我的答案。嘿！谢谢你的帮助！我试图将这一部分添加到我的代码中，但我得到的“FormWithCaptcha”没有定义对不起，朋友，放弃“（）”->recaptcha=FormWithCaptcha（）。是的！我以为那就是你想做的！不过，出于某种原因，我仍然会犯错误。我正在读取存储库以检查错误在哪里
