用戶未在 Django 中進行身份驗證？ 它顯示錯誤

Question

我正在創建一個網站，所以我在登錄頁面中完成了注冊頁面，每個詳細信息都是正確的，但顯示的是請驗證您的詳細信息我的意思是其他部分我也在用戶名和密碼后打印了打印聲明當我輸入時打印相同的詳細信息但是無法訪問登錄。

視圖.py

def sign_in(request):
        
    if request.method == "POST":
        username=request.POST['username']
        password=request.POST['password']
        print(username,password)
        user = authenticate(username=username,password=password)
            
        if user is not None:
            login(request,user)
            messages.success(request,"you are logged successfully ")
            return redirect("front_page")    
        else:
            messages.error(request,"please verify your details")
            return redirect("sign_in")   
    return render(request,"login.html")

def front_page(request):
    return render(request,"frontpage.html")

網址.py

 path('log_in',views.sign_in,name="sign_in"),
 path('front_page',views.front_page,name="front_page"),

html

 <div class="signup-form">
        <form action="{% url 'sign_in' %}" method="POST">
         {% csrf_token %}
         <h2 class="text-center">Login</h2>
         <p class="text-center">Please fill in this form to login your account!</p>
         <hr>
   
         <div class="form-group">
           <div class="input-group">
             <div class="input-group-prepend">
               <span class="input-group-text">
                 <span class="fa fa-user"></span>
                         </span>
             </div> 
             <input type="text" class="form-control" name="username" placeholder="Username" required="required">
           </div>
         </div> 
         
         <div class="form-group">
            <div class="input-group">
              <div class="input-group-prepend">
                <span class="input-group-text">
                  <i class="fa fa-lock"></i>
                </span>                    
              </div>
                <input type="password" class="form-control" name="password" placeholder="Password" required="required">
            </div>
          </div>

          <div class="form-group d-flex justify-content-center">
            <button type="submit" class="btn btn-primary btn-lg">Login</button>
          </div>
          <div class="text-center text-primary">Dont have a account? <a href="{% url 'register' %}">Create here </a></div>
        </form>
       
    </div>

我只想使用用戶名和密碼登錄，但它顯示請驗證您的詳細信息，但所有詳細信息都是正確的。

有任何想法嗎？

authenticate()還需要request作為參數，因此它應該是：

user = authenticate(request,username=username,password=password)

您注冊用戶的視圖應該是這樣的：

def register(request):
if request.method == "POST":
    username=request.POST['username']
    password=request.POST['password']
    confirm_password=request.POST['confirm_password']
    
    if password == confirm_password:    
        if User.objects.filter(username=username).exists():
            messages.info(request,"user name was taken please choose another one")
            return redirect('register')
        else:
            user1=User.objects.create_user(username=username,password=password)
            user1.is_active = False  
         
            messages.success(request,"you account  was created successfully thank you for choosing us ")
            return redirect("sign_in")  
      
    else:
        messages.info(request,"please verify your passwords")
        return redirect('register')   
else:
    return render(request,'register.html')    

Answer 2

您的初始代碼有問題，

def sign_in(request):
        
    if request.method == "POST":
        username=request.POST['username']
        password=request.POST['password']
        print(username,password)
        user = authenticate(username=username, password=password)
            
        if user is not None:
            login(request,user)
            messages.success(request,"you are logged successfully ")
            return redirect("front_page")    
        else:
            messages.error(request,"please verify your details")
            return redirect("sign_in")   
    return render(request,"login.html")

是您正在嘗試對尚未注冊的用戶進行身份驗證。 這類似於我在文檔中找到的代碼，但該代碼用於登錄用戶，而不是注冊用戶。

解決方案是：

def sign_in(request):

    if request.method == "POST":
        username=request.POST['username']
        password=request.POST['password']
        user, created = User.objects.get_or_create(username=username, password=password)
        user = authenticate(username=username, password=raw_password)
        login(request, user)
        return redirect("front_page")

    return render(request,"login.html")

感謝Sunderam指出我的錯誤，function authenticate()確實是hash 密碼，所以它會接受原始密碼。
