How can make a form for redirecting user to the entered address in Django?
问题
我有点困惑，不知道应该如何制作一个简单的表单，该表单接受用户输入的网站 URL，并在点击提交按钮后进行重定向。我应该使用UserCreationForm吗？如果是这样，我应该使用哪些字段？还是应该创建一个自定义表单？
英文:
I am a little confused as to how should I be working on making a simple form that takes a website url input from a user and redirects on clicking the submit form button. Should I be using the UserCreationForm , if so , what fields should I be using for the same. Or should I be creating a custom form for the same .

以下是翻译好的部分：
模板：
<form action="{% url 'my_view' %}" method="POST">{% csrf_token %}<input name="url" type="url"><input type="submit"></form>
视图：
@login_requireddef my_view(request):if request.method == "POST":return redirect(request.POST.get("url"))else:return render(request, "my_template.html")
英文:
Here is a (simplified) example:
Template:
<form action="{% url 'my_view' %}" method="POST">{% csrf_token %}<input name="url" type="url"><input type="submit"></form>
View:
@login_requireddef my_view(request):if request.method == "POST":return redirect(request.POST.get("url"))else:return render(request, "my_template.html")

如果您打算使用文本字段，那么应避免使用表单。创建一个普通的HTML表单，其中包含一个文本输入字段，然后在后端获取该值。
HTML：mytemplate.html
<form method="post">{% csrf_token %}<input type="url" name="url" placeholder="https://example.com" /><input type="submit" value="提交" /></form>
views.py
from django.shortcuts import redirect, renderdef redirect_to_url(request):if request.method == "POST":url = request.POST.get('url')return redirect(url)else:return render(request, 'mytemplate.html', {})
这是一个非常基本的实现。您还可以验证URL是否存在。
import requestsfrom django.shortcuts import redirect, renderfrom django.http import HttpResponsedef redirect_to_url(request):if request.method == "POST":url = request.POST.get('url')resp = requests.get(url)if resp.status_code == 200: # 其他验证和条件return redirect(url)return HttpResponse('无效的URL')else:return render(request, 'mytemplate.html', {})

英文:
If you are going to use a text field then you should avoid forms. Create a normal HTML form with a input type text and get that value in backend.
HTML: mytemplate.html
<form method="post">{% csrf_token %}<input type="url" name="url" placeholder="https://example.com" /><input type="submit" value="Submit" /></form>
views.py
from django.shortcuts import redirect, renderdef redirect_to_url(request):if request.method == "POST":url = request.POST.get('url')return redirect(url)else:return render(request, 'mytemplate.html', {})
This is a very basic implementation. You can also verify if the url exists.
import requestsfrom django.shortcuts import redirect, renderfrom django.http import HttpResponsedef redirect_to_url(request):if request.method == "POST":url = request.POST.get('url')resp = requests.get(url)if resp.status_code == 200: # some other validation and conditionsreturn redirect(url)return HttpResponse('Invalid URL')else:return render(request, 'mytemplate.html', {})
