djangoの2

古鸽或百度的镜子：

 

1､E:\django下建个文件夹名为搜索引擎→PyCharm新建项目选Django→location改为E:\django\搜索引擎→More Settings的Application写个search

***************分割线***************

2､项目文件夹搜索引擎：

 

①settings.py，只改语言和时区

 

②urls.py：

 

from django.conf.urls import url

from django.contrib import admin

from search import views

 

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^$', views.index),

    url(r'^s', views.so),  #搜索网址尾是?及各参数，不加/和$；百度是s，古鸽是search

    url(r'^search', views.so),

]

***************分割线***************

3､应用文件夹search：

 

①新建俩文件夹templates和static：templates里存放复制自谷鸽首页的googleIndex.html，和强子院子写的baiduIndex.html；static放images\so.gif等强子所做的百度前端样式。

②views.py：

 

from django.shortcuts import render

from django.http import HttpResponse

import requests

from fake_useragent import UserAgent

 

def copySearchEngineData(word):

    h = {'User-Agent': UserAgent().random}

    #static文件夹，若是和manage.py同级，则前无/；若用的是在某个应用内建的，则加/

    #html=requests.get('https://www.baidu.com%s' %word,headers=h).text

    #html=html.replace('//www.baidu.com/img/baidu_jgylogo3.gif','/static/images/so.gif')

    s = requests.session()

    javascript=s.get('https://xs5.rqiao.net', headers=h).text.split('cookie\' : "')[1].split('"')[0]

    s.cookies['verynginx_sign_javascript']=javascript

    html = s.get('https://xs5.rqiao.net%s' %word, headers=h).text

    oldLogo='/images/branding/googlelogo/2x/googlelogo_color_120x44dp.png'

    html=html.replace(oldLogo,'/static/images/so.gif')

    return html

 

def index(request):

    return render(request,'googleIndex.html')   #baiduIndex.html

 

def so(request):

    #word=request.GET['wd']    #取输入框的值：text框的name属性的值，百度是wd，古鸽是q

    word=request.get_full_path()  #取网址中不含域名的后半截

    result=copySearchEngineData(word)

    return HttpResponse(result) #展示的是html文件用render，网页源代码则用HttpResponse

③baiduIndex.html：

 

{% load static from staticfiles %}

 

＜!doctype html>

＜html>

    ＜head>＜meta charset="UTF-8">＜title>百度镜像＜/title>＜/head>

 

＜body>

    ＜p style="text-align:center">

        ＜strong>＜span style="color:white;font-size:36px;">更纯净,无广告!＜/span>

        ＜span style="font-size:18px;color:green">绿色的网络搜索环境＜/span>＜/strong>

    ＜/p>

 

    ＜div style="margin:auto;text-align:center;line-height:360px">

        ＜form action="/s" method="get">

        ＜input type="text" name="wd" style="width:500px;height:40px">

        ＜input type="submit" value="百度一下" style="height:45px">

        ＜/form>

    ＜/div>

＜/body>
