分页传参数的两种形式，url正则？id=1

目的：打开http://127.0.0.1:8000/home 点击查看详情转到 http://127.0.0.1:8000/detail-1-1.html实现查看具体信息

一，利用url路由系统的正则表达式传参数

　　url(r'^detail-(?P<uid>d+)-(?P<nid>d+).html',views.detail),

　　def detail(request,uid,nid):

　　　　return

urls:

from django.contrib import admin
from django.urls import path
from cmbd import views
from django.conf.urls import url
urlpatterns = [
    path('admin/', admin.site.urls),
    path('home/', views.home),
    path('home', views.home),
    url(r'^detail-(?P<uid>d+)-(?P<nid>d+).html',views.detail),
]

views:

from django.shortcuts import render,redirect
user_dict = {
    '1':{'name':'hrg','email':'hrg@163.com','pwd':'123'},
    '2':{'name':'eric','email':'hrg@163.com','pwd':'111'},
    '3':{'name':'hhh','email':'hrg@163.com','pwd':'222'},
    '4':{'name':'kkk','email':'hrg@163.com','pwd':'123'},
}

def home(request):
    return render(request,'home.html',{'user_dict':user_dict,})

def detail(request,uid,nid):
    detail_dict = user_dict[uid]
    print(detail_dict)
    return render(request,'detail.html',{'detail_dict':detail_dict,})

templates:

home.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <ul>
        {% for k,v in user_dict.items %}
            <li>
                <span>id:{{ k }}姓名：{{ v.name }}</span>
                <a href="/detail-{{ k }}-1.html">查看详情</a>
            </li>
        {% endfor %}
    </ul>
</body>
</html>


detail.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <h1>用户详情：</h1>
    <ul>
        {% for k,v in detail_dict.items %}
            <li>{{ k }}:{{ v }}</li>
        {% endfor %}
    </ul>
</body>
</html>

二，利用URL地址栏？功能传参数

　　/detail?uid=1&pid=2

urls:

from django.contrib import admin
from django.urls import path
from cmbd import views
from django.conf.urls import url
urlpatterns = [
    path('admin/', admin.site.urls),
    path('home/', views.home),
    path('home', views.home),
    path('detail',views.detail),
]

views:

from django.shortcuts import render,redirect
user_dict = {
    '1':{'name':'hrg','email':'hrg@163.com','pwd':'123'},
    '2':{'name':'eric','email':'hrg@163.com','pwd':'111'},
    '3':{'name':'hhh','email':'hrg@163.com','pwd':'222'},
    '4':{'name':'kkk','email':'hrg@163.com','pwd':'123'},
}

def home(request):
    return render(request,'home.html',{'user_dict':user_dict,})

def detail(request):
    uid = request.GET.get('uid')   #获取home.html中/detail?uid={{ k }}传来的值
    detail_dict = user_dict[uid]
    print(detail_dict)
    return render(request,'detail.html',{'detail_dict':detail_dict,})

templates:

home.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <ul>
        {% for k,v in user_dict.items %}
            <li>
                <span>id:{{ k }}姓名：{{ v.name }}</span>
                <a href="/detail?uid={{ k }}">查看详情</a>
            </li>
        {% endfor %}
    </ul>
</body>
</html>

detail.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <h1>用户详情：</h1>
    <ul>
        {% for k,v in detail_dict.items %}
            <li>{{ k }}:{{ v }}</li>
        {% endfor %}
    </ul>
</body>
</html>
