Django框架中的urls配置：
首先通过pycharm创建一个Django项目：
例如要写blog的功能：则在digango_lesson中的urls代码如下：
"""django_lesson URL Configuration The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/3.0/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: path('', views.home, name='home') Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: path('', Home.as_view(), name='home') Including another URLconf 1. Import the include() function: from django.urls import include, path 2. Add a URL to urlpatterns: path('blog/', include('blog.urls')) """ from django.conf.urls import url from django.contrib import admin from django.urls import path, include from blog import views urlpatterns = [ path('admin/', admin.site.urls), path('show_time/', views.show_time), path('blog/', include('blog.urls')), # 将urls 进行分发 发到blog文件夹下的urls ]
blog项目功能的urls 全部写在 blog文件夹下的urls,如下：
"""django_lesson URL Configuration The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/3.0/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: path('', views.home, name='home') Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: path('', Home.as_view(), name='home') Including another URLconf 1. Import the include() function: from django.urls import include, path 2. Add a URL to urlpatterns: path('blog/', include('blog.urls')) """ from django.conf.urls import url from django.contrib import admin from django.urls import path, include from blog import views urlpatterns = [ url(r'article/(d{4})$/(d{2})', views.article_year), url(r'article/(?P<year>d{4})$/(?P<mouth>d{2})', views.article_year_mouth), # 这种写法参数必须起尖括号里面的名字 url(r'article/(?P<year>d{4})/(?P<mouth>d{2})/(?P<day>d{2})', views.article_year_mouth_day), # 这种写法参数必须起尖括号里面的名字 url(r'register', views.register,name="reg"), # url(r'login', views.login,name="log"), ]
写完url后 要在views中完成功能代码：
from django.shortcuts import render, HttpResponse
import time
# Create your views here.
def show_time(request):
t = time.ctime()
# return HttpResponse("Hellow")
return render(request, "index.html", {"time": t})
def article_year(request, y, m):
return HttpResponse("日期：%s年 %s月" % (y, m))
def article_year_mouth(request, year, mouth):
return HttpResponse("这个日期日期：%s年 %s月" % (year, mouth))
def article_year_mouth_day(request, year, mouth, day):
return HttpResponse("现在的日期：%s年 %s月 %s日" % (year, mouth, day))
def register(request):
if request.method == "POST":
print(request.POST.get("user")) # user
print(request.POST.get("pwd")) # 123
return HttpResponse("success!")
return render(request, "register.html")
# def login(request):
# username = request.GET.get("user")
# password = request.GET.get("pwd")
# if username == "hanhan" and password == "123":
# return render(request, "successful.html")
# else:
# return render(request, "register.html")
用到html应该全部放在templates文件夹中：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>学生注册</h1>
<form action="{% url 'reg' %}" method="post">
<!--{% url 'reg' %} 对应的是blog下面的urls url(r'register', views.register,name="reg"),-->
<p>用户名<input type="text" name="user"></p>
<p>密码 <input type="text" name="pwd"></p>
<p>爱好 <input type="checkbox" name="hobby">篮球
<input type="checkbox" name="hobby">足球
<input type="checkbox" name="hobby">乒乓球
</p>
<p><input type="submit"></p>
</form>
</body>
</html>
如果要加入JS,等文件则需要在settings中配置：
# 加在末尾即可
STATICFILES_DIRS = (
os.path.join(BASE_DIR, "blog/static"),
) # 逗号很重要 static相当于包的名字 固定这样写 才可以找到
HTML中用JS代码如下：
index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
{# {% load staticfiles %}#}
<title>Title</title>
</head>
<body>
<h1>Django，你好,现在时间为:{{time}}</h1>
{#第一种 执行Script 文件 #}
<script src="/static/jquery-3.1.1.js"></script> <!--要放到处理代码后面 -->
{#第二种#}
{#<script src="{% static 'jquery-3.1.1.js' %}"></script>#}
<script>
$("h1").css("color","red")
</script>
</body>
</html>
