python学习笔记（11）Django路由和传值

1. 路由相关

from django.contrib import admin
from django.urls import path
from django.urls.conf import include
from django.urls import re_path  # 正则表达式的路径
from app01 import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path("timer/", views.get_timer),
    path("login/", views.login),
    path("auth", views.auth),
    path("",views.index),
    # 路由系统
    # 路径参数传参
    re_path("article/(\d{4})/(\d+)",views.article_detail),  # 分组，一个()一个分组，这边2个()是2个分组，在article_detail需要加2个参数def article_detail(request,year,month):。
    # 有名分组命名方式就是?P<参数>注意是大写P
    re_path("article_achive/(?P<year>\d{4})/(?P<month>\d+)",views.article_achive),  # 上面是位置传参，可以给参数命名?P<month>方便使用，def article_achive(request,year="2012",month="12")
    # 路由分发
    path("app01/", include("app01.urls")),
    path("app02/", include("app02.urls")),

]

 

2. 数据获取

def index(request):
    
    # 获取请求方式
    print(request.method)
    
    # 获取请求路径不带参数
    print(request.path)
    
    # 获取完整的请求路径
    print(request.get_full_path())
    
    # 请求数据
    print("GET:::",request.GET)
    # GET::: <QueryDict: {'a': ['1'], 'pwd': ['321']}>
    print("GET:::",request.GET.get("pwd"))
    # GET::: 321
    print("POST:::",request.POST)
    # POST::: <QueryDict: {'USER': ['YUAN'], 'PASSWORD': ['3213213213'], 'hobor': ['A', 'B']}>
    print("POST:::",request.POST.get("hobor"))
    # POST::: B
    print("POST_list:::",request.POST.getlist("hobor"))
    # POST::: ['A', 'B']
    # 使用json传值的时候
    print("BODY:::",request.body)
    # BODY::: b'{"user":"yuan","pwd":"wwwwww"}'
    # 使用Json反序列化得到字典
    data = json.loads(request.body.decode())
    print(data)
    # {'user': 'yuan', 'pwd': 'wwwwww'}
    

    # 请求头
    print("请求头：",request.META)
