Reason given for failure:
CSRF token missing or incorrect.

In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django's CSRF mechanism has not been used correctly. For POST forms, you need to ensure:
Your browser is accepting cookies.
The view function uses RequestContext for the template, instead of Context.
In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL.
If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data.
You're seeing the help section of this page because you have DEBUG = True in your Django settings file. Change that to False, and only the initial error message will be displayed.
You can customize this page using the CSRF_FAILURE_VIEW setting.

解決步驟:

1〉django工程settings.py

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',#確認存在
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    # Uncomment the next line for simple clickjacking protection:
    # 'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

2〉html中的form添加模板標簽{% csrf_token %}

<form action="." method="post">{% csrf_token %}

3〉django工程views.py

from django.shortcuts import render_to_response
from django.template import RequestContext

def some_view(request):
    # ...
    return render_to_response('my_template.html',
                              my_data_dictionary,
                              context_instance=RequestContext(request))

P.S如果要屏蔽CSRF

方法1：注釋掉django工程settings.py中

#'django.middleware.csrf.CsrfViewMiddleware'

方法2：django工程views.py添加屏蔽裝飾器

from django.views.decorators.csrf import csrf_exempt 
@csrf_exempt
def some_view(request):
    #...
