尽管我已将名称设置为输入字段，但多值字典键错误

Question

我已经制作了一个表格并设置了 method=post，同时将 request.post['name'] 用于变量 MultiValueDictKeyError 即将到来，这是为什么？

 <form action="verify_user" method="post">
        {% csrf_token %}
        <input required type="text" placeholder="Name" name="name"><br><br>
        <input required type="password" placeholder="Password" name="password"><br><br>
      <input required type="passord" placeholder="Confirm password" name="confirm_password" id="">  <br><br>

        <br><br><h1>{{ messages }}</h1>
        <button type="submit">Create</button>
  </form>

这是我的表格 ------

def verify_user(request):
    inputname = request.POST['name']
    inputpass = request.POST['password']
    inputconfirmpass = request.POST['confirm_password']

    if not inputpass == inputconfirmpass:
        messages.info(request,"Passwords don't match")
    else:
        messages.info(request,"Passwords  match")

    return redirect('/verify_user')

这是我在 views.py 中的 function --------------

MultiValueDictKeyError at /verify_user
  'name'
Request Method: GET
Request URL:    http://127.0.0.1:8000/verify_user
Django Version: 4.1.2
Exception Type: MultiValueDictKeyError
Exception Value:    'name'

这是错误--------

尝试提供另一个名称作为name ，例如person_name的东西，我也建议您使用.get()以便您还可以提供一些其他默认值。

意见.py：

def verify_user(request):
    if request.method=="POST":
        inputname = request.POST.get('person_name', False)
        inputpass = request.POST.get('password', False)
        inputconfirmpass = request.POST.get('confirm_password', False)

        if not inputpass == inputconfirmpass: 
   
            messages.info(request,"Passwords don't match")
        else:        
             messages.info(request,"Passwords  match")

        return redirect('/verify_user')
    else: # GET request
        return render(request, "some_folder_name/your_template.html")

模板文件：

<form method="POST">
        {% csrf_token %}
        <input required type="text" placeholder="Name" name="person_name"><br><br>
        <input required type="password" placeholder="Password" name="password"><br><br>
      <input required type="passord" placeholder="Confirm password" name="confirm_password" id="">  <br><br>

        <br><br><h1>{{ messages }}</h1>
        <button type="submit">Create</button>
  </form>
