settings设置
注：在django中，如果setting里面# 'django.middleware.csrf.CsrfViewMiddleware',被注释，则没有csrf限制，
否则有csrf限制。
如果有csrf有限制或无限制，应用时2则有以下解决方案：
<br>#******************基本应用**********************
# a.（HTML表单中form表单添加）
# { % csrf_token %}
# def csrf1(request):
# if request.method == 'GET':
# return render(request,'csrf1.html')
# else:
# return HttpResponse('哥们干啥来了')
# ***********************************************
#******************全站禁用***********************
# b.(settings设置里面）
# 'django.middleware.csrf.CsrfViewMiddleware',
#************************************************
#******************局部禁用***********************
# c.（全站使用前提下可以使用局部禁用）
# 'django.middleware.csrf.CsrfViewMiddleware',
# from django.views.decorators.csrf import csrf_exempt
# @csrf_exempt
# def csrf1(request):
# if request.method == 'GET':
# return render(request, 'csrf1.html')
# else:
# return HttpResponse('ok')
# ************************************************
# ****************局部使用*************************
# d.（全站禁用前提下可以使用局部使用）
# 'django.middleware.csrf.CsrfViewMiddleware',
# from django.views.decorators.csrf import csrf_protect
# @csrf_protect
# def csrf1(request):
# if request.method == 'GET':
# return render(request, 'csrf1.html')
# else:
# return HttpResponse('ok')
# ************************************************
#****************CBV中添加装饰器********************
# c.特殊CBV
# from django.views import View
# from django.utils.decorators import method_decorator
# @method_decorator(csrf_protect, name='dispatch')
# class Foo(View):
# def get(self, request):
# pass
#
# def post(self, request):
# pass # def wrapper(func):
# def inner(*args,**kwargs):
# return func(*args,**kwargs)
# return inner
# 1. 指定方法上添加装饰器
# class Foo(View): # @method_decorator(wrapper)
# def get(self,request):
# pass # def post(self,request):
# pass
# 2. 在类上添加
# @method_decorator(wrapper,name='dispatch') #全部类添加
# @method_decorator(wrapper, name='get') # 只给get添加
# @method_decorator(wrapper, name='post') # 只给post添加
# class Foo(View): # def dispatch(self,request,*args,**kwargs)
# pass # def get(self,request):
# pass # def post(self,request):
# pass

二.Django之CSRF（Ajax）请求
def csrf1(request):
if request.method == 'GET':
return render(request,'csrf1.html')
else:
return HttpResponse('哥们干啥来了')
views.py<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form method="POST" action="/csrf1.html/">
{% csrf_token %}
<input type="text" name="user">
<input type="submit" value="提交"/>
<a onclick="submitForm();">Ajax提交</a>
</form>
<script src="/static/jquery-3.2.1.js"></script>
<script src="/static/jquery.cookie.js"></script>
<script> 第一种方式：
function submitForm() {
var csrf = $('input[name="csrfmiddlewaretoken"]').val();
var user = $('#user').val();
$.ajax({
url:'/csrf1.html',
type:'POST',
data:{"user":user,'csrfmiddlewaretoken':csrf},
success:function (arg) {
console.log(arg);
} })
} 第二种方式：
{# 获取Console值：在浏览器Console上输入document.cookie#}
function submitForm() {
var token = $.cookie('csrftoken');
var csrf = $('input[name="csrfmiddlewaretoken"]').val();
var user = $('#user').val();
$.ajax({
url:'/csrf1.html',
type:'POST',
headers:{'X-CSRFToken':token},
data:{"user":user},
success:function (arg) {
console.log(arg);
}
})
} </script>
</body>
</html>
