链家 (python)爬虫 成交数据 及 在售数据 爬取

依赖包 lxml requests BeautifulSoup xlwt xlrd Bs4

mac or linux :

sudo pip2.7 install lxml requests BeautifulSoup xlwt xlrd Bs4

windows:

pip2.7 install lxml requests BeautifulSoup xlwt xlrd Bs4

分析程序需要安装anaconda3.

项目目录说明:

HomeLinkTest : Android 工程(用于破解链家App签名验证内容)

jsonSource: 链家客户端json传内容样本,包含(成交商品列表页,成交商品详情页,成交商品更多内容页)(在售商品列表页,在售商品详情页,在售商品更多内容页)

spider:链家爬虫脚本(python脚本)(爬取PC端在线数据,移动端在售数据和成交数据)

爬虫脚本基于python2.7,jupyter-notebook基于python3

#前言:链家数据爬虫,本文采用两种方式

1.常见的分析PC端HTML进行数据爬取(简单实现在售数据爬取,成交数据需要在移动端查看)

2.破解链家移动端签名密钥,使用客户端接口进行爬取(在售数据及成交数据爬取)

实现功能:

一. web界面爬取

爬取web界面在售内容 https://bj.lianjia.com/ershoufang/ 仅爬取在售内容

python2.7 LianjiaSpider/spider/salingInfoSpider.py

爬取web界面成交内容 https://bj.lianjia.com/chengjiao/

python2.7 LianjiaSpider/spider/chengJiaoSpider.py

二.移动端数据爬取(在售,成交)

基于链家app:https://bj.lianjia.com/ 针对其签名校验进行破解

获取对应的json内容,进行自动爬取(仅做技术交流,请勿进行商业应用或其他侵权行为)

在售数据爬取:

python2.7 LianjiaSpider/spider/zaishou/zaiShouSpider.py

成交数据爬取:

python2.7 LianjiaSpider/spider/zaishou/chengJiaoJiaSpider.py

在售及成交数据自动爬取:

python2.7 LianjiaSpider/spider/Spider_Thread_Manager.py

三.jupyter-notebook分析

安装anaconda3, 在终端中运行jupyter-notebook 然后在弹出网页中打开analysis.ipynb或者 单价因子.ipynb

四.爬取小区数据并作图

python3 plotArea.py [city] [area]

然后在 fig/default目录里查看图片。
