仅在IE9上提交django表单的HTTP 403

2023年1月30日 154次阅读

我正在研究Django 1.4.2版.

我已经实现了这个简单的表单示例(灵感来自
djangobook)：

# views.py

from django.shortcuts import render
from django.http import HttpResponseRedirect
from django.core.mail import send_mail
from mysite.contact.forms import ContactForm

def contact(request):
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
            send_mail(
                cd['subject'],
                cd['message'],
                cd.get('email', 'noreply@example.com'),
                ['siteowner@example.com'],
            )
            return HttpResponseRedirect('/contact/thanks/')
    else:
        form = ContactForm()
    return render(request, 'contact_form.html', {'form': form})

# contact_form.html

<html>
<head>
    <title>Contact us</title>
</head>
<body>
    <h1>Contact us</h1>

    {% if form.errors %}
        <p style="color: red;">
            Please correct the error{{ form.errors|pluralize }} below.
        </p>
    {% endif %}

    <form action="" method="post">
        <table>
            {{ form.as_table }}
            {% csrf_token %}
        </table>
        <input type="submit" value="Submit">
    </form>
</body>
</html>

# forms.py

from django import forms

class ContactForm(forms.Form):
    subject = forms.CharField()
    email = forms.EmailField(required=False)
    message = forms.CharField()

一切都适用于我尝试过的所有浏览器(chrome,maxthon,firefox),但在IE9中,我得到了HTTP 403拒绝.

关于导致什么的任何线索？

编辑：经过深入调查后,我发现问题来自于：当询问空表格时,导航器会收到csrf cookie,但由于未知原因,它在发布表单时不会发回这个cookie.这个问题似乎只有当cookie来自pythonanywhere.com的nginx服务器时才会出现,当我从我自己的apache服务器测试时,cookie被发送回来确定.

以下是从服务器捕获的两个标头：

HTTP/1.1 200 OK
Server: nginx/1.2.5
Date: Wed, 21 Nov 2012 13:56:31 GMT
Content-Type: text/html; charset=utf-8
Transfer-Encoding: chunked
Connection: keep-alive
Vary: Cookie
Set-Cookie: csrftoken=1AJjzkbUgJdKAmkbiHicJ3or2Mfi6AbD; expires=Wed, 20-Nov-2013 13:56:31 GMT; Max-Age=31449600; Path=/

HTTP/1.1 200 OK
Date: Wed, 21 Nov 2012 13:56:50 GMT
Server: Apache/2.2.15 (CentOS)
Vary: Cookie
Set-Cookie:  csrftoken=2iMZSH1s0vJnEt4tRRY7FciT1Q7orrVF; expires=Wed, 20-Nov-2013 13:56:50 GMT; Max-Age=31449600; Path=/
Keep-Alive: timeout=180, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/html; charset=utf-8

唯一显着的区别似乎是来自apache的Kee-Alive标题……

你认为它可以来自那里吗？

最佳答案 {％csrf_token％}输出< input type =“hidden”…>标签,也许IE9忽略它,因为它是表的直接子,而不是在单元格内.

尝试在< input type =“submit”value =“Submit”>旁边移动{％csrf_token％}
