谷鸽或百度的镜像:


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


② urls.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,谷鸽是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 baidu Index.html; static放 images\so.gif等强子所做的百度前端样式。

******分割线******

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,Google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>
