1，通过路由反向解析进行重定向

1.1 添加视图函数

myshop/app2/views.py

from django.http import HttpResponse
from django.shortcuts import render
from django.urls import reverse
def index(request):
    return HttpResponse("app2 的index")

# 反向解析
def url_reverse(request):
    # 使用reverse()方法反向解析
    print('解析结果：'+ reverse("app2_url_reverse"))  #  使用reverse()方法反向解析 ,reverse("app2_url_reverse") 对应urls的 name='app2_url_reverse'
    return render(request, "2/url_reverse.html")


def test_get(request):
    print(request.get_host()) # 域名加端口
    print(request.build_absolute_uri()) # 获取完整的请求URI，包括查询字符串
    print(request.path) # 获取访问路径，不含参数
    print(request.get_full_path()) # 获取访问路径，不含参数
    print(request.method) # 获取请求中使用的HTTP方式(POST/GET)
    print(request.GET)  # 获取GET请求的参数
    print(request.META["HTTP_USER_AGENT"]) # 用户浏览器的user-agent字符串
    print(request.META["REMOTE_ADDR"]) # 客户端IP地址
    print(request.GET.get('username')) # 获取get参数

    return HttpResponse("")

# 获取请求中的使用HTTP方式(POST/GET)
def test_post(request):
    print(request.method)
    print(request.POST.get('username'))
    return render(request, '2/test_post.html')


def test_response(request):
    response = HttpResponse()
    response.write("<h1>hello django</h1>")
    response.write("<br>")
    response.write(response.content)
    response.write("<br>")
    response.write(response['Content-Type'])
    response.write("<br>")
    response.write(response.status_code)
    response.write("<br>")
    response.write(response.charset)
    response.write("<br>")

    return response



def test_render(request):
    return render(request, '2/test_render.html', {'info':'hello django'}, content_type='text/html; charset=utf-8')



from django.shortcuts import redirect

def test_redirect_views(request):
    return redirect('test_render')

1.2 添加路由地址

myshop/app2/views.py

from django.urls import path, re_path
from . import views


urlpatterns = [
    path('index', views.index, name='index'),
    path('url_reverse', views.url_reverse, name='app2_url_reverse'), #  使用reverse()方法反向解析 ,name对于视图的reverse("app2_url_reverse")

    path('test_get', views.test_get, name='test_get'),

    path('test_post', views.test_post, name='test_post'),

    path('test_response', views.test_response, name='test_response'),

    path('test_render', views.test_render, name='test_render'),


    path('test_redirect_views', views.test_redirect_views, name='test_redirect_views'),

]

1.3 访问页面

http://127.0.0.1:8000/app2/test_redirect_views 

重定向至http://127.0.0.1:8000/app2/test_render

 2，通过绝对的或相对的URL，让浏览器跳转到指定的URL进行重定方向

2.1 添加视图函数

myshop/app2/views.py

from django.http import HttpResponse
from django.shortcuts import render
from django.urls import reverse
def index(request):
    return HttpResponse("app2 的index")

# 反向解析
def url_reverse(request):
    # 使用reverse()方法反向解析
    print('解析结果：'+ reverse("app2_url_reverse"))  #  使用reverse()方法反向解析 ,reverse("app2_url_reverse") 对应urls的 name='app2_url_reverse'
    return render(request, "2/url_reverse.html")


def test_get(request):
    print(request.get_host()) # 域名加端口
    print(request.build_absolute_uri()) # 获取完整的请求URI，包括查询字符串
    print(request.path) # 获取访问路径，不含参数
    print(request.get_full_path()) # 获取访问路径，不含参数
    print(request.method) # 获取请求中使用的HTTP方式(POST/GET)
    print(request.GET)  # 获取GET请求的参数
    print(request.META["HTTP_USER_AGENT"]) # 用户浏览器的user-agent字符串
    print(request.META["REMOTE_ADDR"]) # 客户端IP地址
    print(request.GET.get('username')) # 获取get参数

    return HttpResponse("")

# 获取请求中的使用HTTP方式(POST/GET)
def test_post(request):
    print(request.method)
    print(request.POST.get('username'))
    return render(request, '2/test_post.html')


def test_response(request):
    response = HttpResponse()
    response.write("<h1>hello django</h1>")
    response.write("<br>")
    response.write(response.content)
    response.write("<br>")
    response.write(response['Content-Type'])
    response.write("<br>")
    response.write(response.status_code)
    response.write("<br>")
    response.write(response.charset)
    response.write("<br>")

    return response


def test_render(request):
    return render(request, '2/test_render.html', {'info':'hello django'}, content_type='text/html; charset=utf-8')



from django.shortcuts import redirect

def test_redirect_views(request):
    return redirect('test_render')


def test_redirect_url(request):
    return redirect('http://www.baidu.com')

2.2 添加路由地址

myshop/app2/urls.py

from django.urls import path, re_path
from . import views


urlpatterns = [
    path('index', views.index, name='index'),
    path('url_reverse', views.url_reverse, name='app2_url_reverse'), #  使用reverse()方法反向解析 ,name对于视图的reverse("app2_url_reverse")

    path('test_get', views.test_get, name='test_get'),

    path('test_post', views.test_post, name='test_post'),

    path('test_response', views.test_response, name='test_response'),

    path('test_render', views.test_render, name='test_render'),


    path('test_redirect_views', views.test_redirect_views, name='test_redirect_views'),

    path('test_redirect_url', views.test_redirect_url, name='test_redirect_url'),
]

2.3 访问页面

http://127.0.0.1:8000/app2/test_redirect_url

重定向至百度一下，你就知道 (baidu.com)
