一、模板渲染
render(request, template_name, context=None, content_type=None, status=None, using=None) 返回一个HttpResponse对象 
from django.urls import path, re_path, include from mysite import views urlpatterns = [ path("index/", views.my_index) ] from django.shortcuts import render def my_index(request): num = 100 # 传递数值 username = "Zhang Shan" # 传递字符串 ls = ["aa", "bb", "cc"] # 传递列表 d = { "k1":"v1", "k2":"v2", "x3":{ "aa":111, "bb":222}} # 传递字典 class Person: # 传递对象 def __init__(self, name, age, sex): self.name = name self.age = age self.sex = sex def run(self): return "running{}".format(self.name) p1 = Person("li shi", 20, "male") import datetime time = datetime.datetime.now() # 传递时间 tag = "<a href='http//www.baidu.com'>百度首页</a>" # 传递标签 ct = { "num":num, "username":username, "ls":ls, "d":d, "person":p1, "time":time, "tag":tag } # context=locals()，会把全部本地变量的值传递到前端页面 return render(request, "index.html", context=ct)

<br>
根据字典的键获取值：{
{ d.k1 }} <!-- 不能写成d."k1"-->
<br>
字典嵌套取值：{
{ d.x3 }}
<br>
字典嵌套取里面的值：{
{ d.x3.aa }}
