介绍 ： django项目开发必须懂的知识点，下面使用的数据库是mysql ,
models.py 数据库表结构，
# -*- coding: utf-8 -*- from __future__ import unicode_literals from django.db import models # Create your models here. class Test(models.Model): name = models.CharField(max_length=20)
1、GET 请求：
urls.py
"""pythondjango URL Configuration The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/1.11/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: url(r'^$', views.home, name='home') Class-based views 1. Add an import: from other_app.views import Home 2.

2、POST请求（重要）
注意：请求之后，经过我们自己的逻辑处理后，如何返回到页面并且解析： 新建一个search2.py
# -*- coding: utf-8 -*- from django.shortcuts import render from django.views.decorators import csrf # 接收POST请求数据 def search_post(request): ctx = {'rlt': 10000} print request.POST if request.POST: ctx['rlt'] = request.POST['q'] return render(request, "post.html", ctx) urls.py

{
{ rlt }}结果：
注意：
在模板的末尾，我们增加一个 rlt 记号，为表格处理结果预留位置。
表格后面还有一个{% csrf_token %}的标签。csrf 全称是 Cross Site Request Forgery。这是Django提供的防止伪装提交请求的功能。POST 方法提交的表格，必须有此标签。
