实现原理:

  • urls.py:

from django.conf.urls import url
from django.contrib import admin
from app01 import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    # url(r'^index/', views.index),
    url(r'^asdfasdfasdf/(\d+)/(\d+)/', views.index, name='indexx'),
    url(r'^login/', views.login),
    # url(r'^home/', views.home),
    # views.Home.as_view()是固定用法
    url(r'^home/', views.Home.as_view()),
    # url(r'^detail/', views.detail),
    url(r'^detail-(\d+).html', views.detail),
    # url(r'^detail-(\d+)-(\d+).html', views.detail),
    # url(r'^detail-(?P<nid>\d+)-(?P<uid>\d+).html', views.detail),
]

  • 修改views.py:
from django.shortcuts import render,HttpResponse,redirect

# Create your views here.

# USER_DICT = {
#     'k1': 'root1',
#     'k2': 'root2',
#     'k3': 'root3',
#     'k4': 'root4',
# }

USER_DICT = {
    '1': {'name': 'root1', 'email': 'root@live.com'},
    '2': {'name': 'root2', 'email': 'root@live.com'},
    '3': {'name': 'root3', 'email': 'root@live.com'},
    '4': {'name': 'root4', 'email': 'root@live.com'},
    '5': {'name': 'root5', 'email': 'root@live.com'},
}


def index(request,nid,unid):
    # indexx
    print(request.path_info)
    # /asdfasdfasdf/13/
    # reverse 能反转
    from django.urls import reverse
    v = reverse('indexx', args=(90,88,))

    print(v)

    return render(request, 'index.html', {'user_dict': USER_DICT})


# def detail(request):
#     nid = request.GET.get('nid')
#     detail_info = USER_DICT[nid]
#     return render(request, 'detail.html', {'detail_info': detail_info})


def detail(request, nid):
    # print(nid, uid)
    # return HttpResponse(nid)
    detail_info = USER_DICT[nid]
    return render(request, 'detail.html', {'detail_info': detail_info})


'''
def login(request):
    # 判断用户获取数据方式是GET,就返回什么数据
    if request.method == "GET":
        return render(request, 'login.html')
    # 判断用户获取数据方式是POST,就判断用户提交的数据是否正确
    elif request.method == "POST":
        u = request.POST.get('user')
        p = request.POST.get('pwd')
        if u == 'alex' and p == '123':
            return redirect('/index/')
        else:
            return render(request, 'login.html')
    else:
        # PUT,DELETE,HEAD,OPTION...
        return redirect("/index/")

'''


def login(request):
    # 判断用户获取数据方式是GET,就返回什么数据
    if request.method == "GET":
        return render(request, 'login.html')
    # 判断用户获取数据方式是POST,就判断用户提交的数据是否正确
    elif request.method == "POST":
        # radio
        # v = request.POST.get('gender')
        # print(v)

        v = request.POST.get('fff')
        print(v)
        # 所有上传文件都上传到request.FILES
        obj = request.FILES.get('fff')
        print(obj, type(obj), obj.name)

# def home(request):
#     return HttpResponse('Home')


from django.views import View


class Home(View):

    # 调用父类中的dispatch(相当于助理,)
    def dispatch(self, request, *args, **kwargs):
        print('before')
        result = super(Home,self).dispatch(request, *args, **kwargs)

    def post(self,request):
        print(request.method, 'POST')
        return render(request, 'home.html')

  • 修改index.html:
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <form action="{{ request.path_info }}" method="post">
        <p><input type="text" name="user" placeholder="用户名"></p>
        <p><input type="text" name="email" placeholder="邮箱"></p>
        <input type="submit" value="提交">
    </form>

    <ul>
        {% for k,row in user_dict.items %}
        <!--target="_blank"表示在新页面打开-->
        <li><a target="_blank" href="/detail-{{ k }}.html">{{ row.name }}</a></li>
        {% endfor %}
    </ul>

</body>
</html>

  • @进一步:

  • index.html:
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <form action="{% url 'indexx' nid=1 uid=3 %}" method="post">
        <p><input type="text" name="user" placeholder="用户名"></p>
        <p><input type="text" name="email" placeholder="邮箱"></p>
        <input type="submit" value="提交">
    </form>

    <ul>
        {% for k,row in user_dict.items %}
        <!--target="_blank"表示在新页面打开-->
        <li><a target="_blank" href="/detail-{{ k }}.html">{{ row.name }}</a></li>
        {% endfor %}
