djangoの2

Posted 2020-10-12

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

 

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，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(wd):

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

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

    #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=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‘ %wd, 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，B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：
