Question

我在这里尝试使用“记住我”选项登录，但是此代码无法正常工作。如果未选中“ remember_me”复选框，则它不会登录；如果还选中了“记住我”选项，则它将登录但注销后，登录表单中还没有用户名和密码。我该如何实现Remember_me选项，还有更好的主意吗？

forms.py

from django import forms
class LoginForm(forms.Form):
    username = forms.CharField(max_length=100)
    password = forms.CharField(widget=forms.PasswordInput)
    remember_me = forms.BooleanField()

模板

<form action="" method="post" class="form-signin">
                  {% csrf_token %}
                <input type="text" class="form-control mb-2" name='username' placeholder="Username" required autofocus>
            <input type="password" class="form-control mb-2" name='password' placeholder="Password" required>
                <button class="btn btn-lg btn-primary btn-block mb-20" type="submit">Sign in</button>
                  <div class="checkbox float-left">
                    <input type="checkbox"  name="remember_me" id="basic_checkbox_1" >
                    <label for="basic_checkbox_1">Remember me</label>
                  </div>
                <a href="#" class="float-right">Need help?</a>
              </form>

views.py

if request.method == 'POST':
        form = LoginForm(request.POST or None)
        if form.is_valid():
            username = form.cleaned_data['username']
            password = form.cleaned_data['password']
            remember_me = form.cleaned_data['remember_me']
            user = authenticate(request,username=username,password=password)
            if user:
                login(request,user)
                if not remember_me:
                    request.session.set_expiry(0)
                redirect_url = request.GET.get('next', 'home')
                messages.success(request, 'logged in.')
                return redirect(redirect_url)
            else:
                messages.error(request,'Invalid username or password')
    else:
        form = LoginForm()
    return render(request,'login.html',{'form':form})

您一切正常。当用户选中记住我时，您必须使用permanent/persistence cookies（这是django的默认行为）。如果用户未选中记住我，则必须使用session cookies。 永久性/持久性COOKIES 有有效期，会话COOKIES 没有有效期。当用户关闭浏览器时，会话COOKIES 被删除。 request.session.set_expiry(0)这将帮助您设置会话COOKIES 。
