Python django 1.11.6 csrf_令牌值是否为空？

设置.py

MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

@csrf_protect #ensure_csrf_cookie....etc i tried it.
def category(request):
    context = RequestContext(request)
    dic = {
        'a': 'aaaa',
        'b': 'bbb'
    }
    return render_to_response('cate.html', dic, context_instance=context)

myview.py

MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',

    dic = {
        'a': 'aaaa',
        'b': 'bbb'
    }
    return render_to_response('cate.html', dic, context_instance=context)

cate.html

<form name="cateForm" id="cateForm" method="POST">
    {% csrf_token %}
    <input type="text" name="href" id="href" size="50">
</form>

{%csrf_令牌%}

如果我查看源代码，那么csrf_标记值为空。

不要使用

呈现到\u响应，它已经过时了。使用
渲染

def category(request):
    dic = {
        'a': 'aaaa',
        'b': 'bbb'
    }
    return render(request, 'cate.html', dic)

不要使用
render\u to\u response
，它已经过时了。使用
渲染

def category(request):
    dic = {
        'a': 'aaaa',
        'b': 'bbb'
    }
    return render(request, 'cate.html', dic)

render_to_响应函数的context_实例参数已弃用，并已在Django 1.10中删除。这里讨论了这个问题：.
