CSRF跨域访问保护
当我们打开此功能时，在提交时就会报错，此时解决方法有
1.浏览器支持cookie
2.有render方法
3.在提交的表单中加入{% csrf_token%}，为了生成随机值。
现在我们就以第三种为例,就可以解决此类问题了
1 {% extends "index.html" %}
2
3 {% block extra-head-resources %}
4
5 <script src="/static/plugins/ckeditor/ckeditor.js"></script>
6 {% endblock %}
7
8 {% block container %}
9
10 <div style="min-height: 600px;padding-bottom: 50px">
11
12 <form method="post" enctype="multipart/form-data"> {% csrf_token %}
13
14 {% for field in form %}
15 <div class="form-group">
16 <label class="col-sm-2 control-label">{{ field.name }}</label>
17 <div class="col-sm-10">
18 {{ field }}
19 <span style="color: red">{{ field.errors }}</span>
20 </div>
21 </div>
22
23 {% endfor %}
24 <input type="submit" class="col-lg-offset-5 btn btn-sm btn-success" value="提交">
25 </form>
26 </div>
27
28
29 <script>
30 // Replace the <textarea id="editor1"> with a CKEditor
31 // instance, using default configuration.
32 CKEDITOR.replace( ‘id_body‘ );
33 </script>
34
35
36 {% endblock %}
new_article.html
为了防止CSRF攻击，分辨来源，将随机值放在页面中，而不是放在POST请求中，这样就不会被恶意使用。
Middleware中间件
为了能使用户对django的request/response请求处理过程及请求数据包进行全局的更改，比如对所有的请求进行是否已登录的验证，是否有注入或其他攻击行为的检测等，django提供了一个轻量级、底层的钩子插件，就叫中间件。
MIDDLEWARE = [
‘django.middleware.security.SecurityMiddleware‘, 进行一些请求的安全验证，xss攻击过滤，ssl重定向（自动重定向到https）
‘django.contrib.sessions.middleware.SessionMiddleware‘, 启用对session的支持
‘django.middleware.common.CommonMiddleware‘, 做一些常用的小功能，检测url，会自动把foo.com/bar，重定向程foo.com/bar/
‘django.middleware.csrf.CsrfViewMiddleware‘, 跨域请求保护
‘django.contrib.auth.middleware.AuthenticationMiddleware‘, 认证
‘django.contrib.messages.middleware.MessageMiddleware‘, 启用django自带的消息日志插件
‘django.middleware.clickjacking.XFrameOptionsMiddleware‘, 点击劫持
]
自定义中间件
要在settings中，将自己创建的申明
1 MIDDLEWARE = [ 2 ‘django.middleware.security.SecurityMiddleware‘, 3 ‘django.contrib.sessions.middleware.SessionMiddleware‘, 4 ‘django.middleware.common.CommonMiddleware‘, 5 ‘django.middleware.csrf.CsrfViewMiddleware‘, 6 ‘django.contrib.auth.middleware.AuthenticationMiddleware‘, 7 ‘django.contrib.messages.middleware.MessageMiddleware‘, 8 ‘django.middleware.clickjacking.XFrameOptionsMiddleware‘, 9 ‘bbs.test_middleware.SimpleMiddleware‘ 10 ]
settings
1 from django.shortcuts import render,HttpResponse,redirect
2 class SimpleMiddleware(object):
3 def __init__(self, get_response):
4 self.get_response = get_response
5 # One-time configuration and initialization.
6
7
8 def __call__(self, request):
9 # Code to be executed for each request before
10 # the view (and later middleware) are called.
11
12 response = self.get_response(request)
13 print("middleware",response)
14
15 # Code to be executed for each request/response after
16 # the view is called.
17
18 return response
19 def process_view(self,request,view_func,view_args,view_kwargs):
20 print(‘process view‘,self,request,view_func,view_args,view_kwargs)
21 def process_exception(self,request,exception):
22 print(‘process excetion‘,request,exception)
23 return HttpResponse(‘error happend....%s‘ % exception)
24
25 def process_template_reponse(self,request,response):
26 print(‘process_template_reponse‘,request,response)
