视图

myapp/views.py文件中，定义一个函数可以称为视图函数，简称视图。它接收处理请求，并响应请求。

实现一个小实例

# myproject/urls.pyfrom django.contrib import adminfrom django.urls import path, includefrom .myapp import urlsurlpatterns = [    path('admin/', admin.site.urls),    path('myapp/', include(urls)),]# myproject/myapp/urls.pyfrom django.urls import pathfrom . import viewsurlpatterns = [    path('', views.home, name='home'),    path('index//', views.index, name='index'),]# myproject/myapp/views.pyfrom django.shortcuts import renderdef index(request, name, age):    data = {'name': name, 'age': age}    return render(request, 'myapp/index.html', data)# myproject/myapp/templates/myapp/index.html

请求name: {{ name }}

请求age: {{ age }}

最终显示效果

实现GET请求实例

# myproject/myapp/urls.pyfrom django.urls import path, re_pathfrom . import viewsurlpatterns = [    path('index//', views.index, name='index'),    # 用户模块    re_path('^user.html$', views.user_html, name='user_html'),    re_path('^user_get$', views.user_get, name='user_get'),]# myproject/myapp/views.pyfrom django.http import HttpResponsefrom django.shortcuts import renderfrom django.views.decorators.http import require_http_methodsdef index(request, name, age):    data = {'name': name, 'age': age}    return render(request, 'myapp/index.html', data)def user_html(request):    return render(request, 'myapp/user/user_html.html')@require_http_methods(['GET'])def user_get(request):    first_name = request.GET.get('first_name')    last_name = request.GET.get('last_name')    return HttpResponse('

success

姓：'+ first_name +'

名：'+ last_name +'

user_html.html

user_html.html页面

提交后显示结果

实现POST请求实例

# myproject/myapp/urls.pyfrom django.urls import path, re_pathfrom . import viewsurlpatterns = [    path('index//', views.index, name='index'),    # 用户模块    re_path('^user.html$', views.user_html, name='user_html'),    re_path('^user_post$', views.user_post, name='user_post'),]# myproject/myapp/views.pyfrom django.http import HttpResponsefrom django.shortcuts import renderfrom django.views.decorators.http import require_http_methodsdef index(request, name, age):    data = {'name': name, 'age': age}    return render(request, 'myapp/index.html', data)def user_html(request):    return render(request, 'myapp/user/user_html.html')@require_http_methods(['POST'])def user_post(request):    first_name = request.POST.get('first_name')    last_name = request.POST.get('last_name')    return HttpResponse('

post success

姓：'+ first_name +'

名：'+ last_name +'

user_html.html
