python EasyUI + Django--整合 CSRF 防护去除
先来张完整图：
关于Django 得CSRF 中间件 防护 GET 是不做CSRF验证得 但POST 默认验证 $.cookie(‘csrftoken‘)) "value"
第一种方法： 在主配置文件 settings.py 中去除中间件
第二种： 无需 注销 第一种方法 #‘django.middleware.csrf.CsrfViewMiddleware‘,
在Views.py 中引入 from django.views.decorators.csrf import csrf_exempt ,csrf_protect
在需要得方法前添加 @csrf_exempt 不启用CSRF 反之 @csrf_protect
第三种： 通过CSRF 验证 FORM 表单 加入{% csrf_token %}
ajax通过CSRF验证：
$.ajax({ url: ‘/remove/‘, type: ‘POST‘, data: {id:row.id}, headers: {‘X-CSRFtoken‘: $.cookie(‘csrftoken‘)},
定义全局ajax headers请求头 CSRF验证
$(function (){
$.ajaxSettings({
beforeSend: function(xhr,settings){
xhr.setRequestHeader(‘X-CSRFtoken‘, $.cookie(‘csrftoken‘))
}
})
});
models 表结构代码
from django.db import models
#根据类对象生成表结构
#python manage.py makemigrations
#根据表结构生成对应数据库表 SQLite
#python manage.py migrate
class Person(models.Model):
Uesr_name = models.CharField(max_length=32)
User_sex = models.CharField(max_length=32, null=True,blank=True)
User_phone=models.IntegerField(max_length=255, null=True,blank=True)
User_addre=models.CharField(max_length=32, null=True,blank=True)
urls.py URL代码
from django.conf.urls import url from django.contrib import admin from App.views import * urlpatterns = [ url(r‘^admin/‘, admin.site.urls), url(r‘^$‘,indexl), url(r‘^start/‘, app_start), url(r‘^read/‘, Read_all_SQL), url(r‘^edit/(?P<id>\d+)‘, Edit_UserNmae), url(r‘^remove/‘, Remove_US_ID), ]
