Question

我正在尝试通过ajax提交表单。我的模板如下：-

<form method="POST" id="form1" class="SignUP signupform">
        <div class="classheading">Sign-up</div>
        {% csrf_token %}
        <input type="text" name="user" placeholder="Username" class="sinput" required="true" />
        <input type="text"name="email" placeholder="Email" class="sinput" required="true"/>
        <input type="password"name="password"placeholder="Password" class="sinput" required="true"/>
        <input type="password"placeholder="Re-enter Password" class="sinput" required="true"/>
        <button type="submit" class="subform">Sign Up</button>
</form>

提交此表单的ajax视图是：-

$(document).ready(function(){
    $('#form1').submit(function(){
    console.log('form is submitted');

    var csrftoken = $("[name=csrfmiddlewaretoken]").val();

    var formdata={
        'username':$('input[name=user]').val(),
        'email':$('input[name=email]').val(),
        'password1':$('input[name=password]').val(),
        'password2':$('input[name=password1]').val(),
    };
    console.log("Formvalue is taken");

    $.ajax({
        type:'POST',
        url:'/Submit/signingup',
        data:formdata,
        dataType:'json',
        encode:true,
        headers:{
        "X-CSRFToken": csrftoken
        },
    })

    .done(function(data){
        console.log(data);
    });


    event.preventDefault();
});
 });

在后端，我正在使用Django提交此表单。相应的视图如下：-

@csrf_protect
def signup(request):
if request.method == 'POST':
    form = SignupForm(request.POST)
    if form.is_valid():
        user = form.save(commit=False)
        user.is_active = False
        user.save()
        current_site = get_current_site(request)
        mail_subject = 'Activate your blog account.'
        message = render_to_string('acc_active_email.html', {
            'user': user,
            'domain': current_site.domain,
            'uid':urlsafe_base64_encode(force_bytes(user.pk)).decode(),
            'token':account_activation_token.make_token(user),
        })
        to_email = form.cleaned_data.get('email')
        email = EmailMessage(
                    mail_subject, message, to=[to_email]
        )
        email.send()
        return HttpResponse("Confirm your email.")
else:
     return JsonResponse({'success': False,'errors': [(k, v[0]) for k, v in form.errors.items()]})

但是它显示403错误。在命令提示符下，它显示“ CSRF_TOKEN丢失或不正确”。可能是什么错误？

Answer 1

像这样从打开标记后立即输入csrf_token。并尝试

<form method="POST" id="form1" class="SignUP signupform">{% csrf_token %}

Answer 2

尝试

mypal <- colorNumeric(palette = "viridis", domain = d$A)

    leaflet() %>% 
      addProviderTiles("OpenStreetMap.Mapnik") %>%
      setView(lat = 39.8283, lng = -98.5795, zoom = 4) %>%
      addPolygons(data =

USA, stroke = TRUE, color='black', opacity=1, weight=.5, smoothFactor = 0.2, fillOpacity = 1,
                  fillColor = ~mypal(d$A),
                  popup = paste('<b>',d$state, "</b><br>A:", d$A) %>%
      addLegend(position = "bottomleft", pal = mypal, values = d$A,
                title = "A",
                opacity = 1)

Django表单提交中缺少CSRF令牌
