一、说明
1.1 开发环境说明
开发环境--PyCharm
爬虫框架--Scrapy
开发语言--Python 3.6
安装第三方库--Scrapy、pymysql、matplotlib
数据库--MySQL-5.5（监听地址--127.0.0.1:3306，用户名--root，密码--root，数据库--anjuke）
1.2 程序简要说明
本程序以安居客-深圳为例，其他城市使用的是一样的结构爬取其他程序基本修改start_urls和rules中的url即可移植
本程序实现安居客新楼盘和二手房的信息爬取，还存在一些小问题，但算基本可用
程序的总体思路是：使用CrawlSpider爬虫----从start_urls开始爬行----爬行到的url如果符合某个rule就会自动调用回调函数----回调函数使用xpath解析和获取楼盘信息item----pipe将传过来的item写入数据库--report脚本从数据库中读出数据生成图表
新楼盘和二手房爬取的区别是，新楼盘没有反爬虫机制。二手房一是限制了访问频率，如果超过某个频率就需要输入验证码才能访问（我这里通过限制5秒发一个请求进行处理），二是二手房信息页面经过javascript处理，禁用javascript时信息处理div[4]启用javascript时信息被移动到div[3]，scrapy默认是不运行javascript的所以需要使用禁用javascript时的路径才能获取信息。

二、创建数据库表结构
sql创建代码：
# Host: localhost (Version: 5.5.53)
# Date: 2018-06-06 18:27:08
# Generator: MySQL-Front 5.3 (Build 4.234) /*!40101 SET NAMES utf8 */; #
# Structure for table "sz_loupan_info"
# CREATE TABLE `sz_loupan_info` (
`loupan_name` varchar(255) DEFAULT NULL,
`loupan_status` varchar(255) DEFAULT NULL,
`loupan_price` int(11) DEFAULT NULL,
`loupan_discount` varchar(255) DEFAULT NULL,
`loupan_layout` varchar(255) DEFAULT NULL,
`loupan_location` varchar(255) DEFAULT NULL,
`loupan_opening` varchar(255) DEFAULT NULL,
`loupan_transfer` varchar(255) DEFAULT NULL,
`loupan_type` varchar(255) DEFAULT NULL,
`loupan_age` varchar(255) DEFAULT NULL,
`loupan_url` varchar(255) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC; #
# Structure for table "sz_sh_house_info"
# CREATE TABLE `sz_sh_house_info` (
`house_title` varchar(255) DEFAULT NULL,
`house_cost` varchar(255) DEFAULT NULL,
`house_code` varchar(255) DEFAULT NULL,

`house_kind` varchar(255) DEFAULT NULL,
`house_layout` varchar(255) DEFAULT NULL,
`house_size` varchar(255) DEFAULT NULL,
`house_face_to` varchar(255) DEFAULT NULL,
`house_point` varchar(255) DEFAULT NULL,
`house_price` varchar(255) DEFAULT NULL,
`house_first_pay` varchar(255) DEFAULT NULL,
`house_month_pay` varchar(255) DEFAULT NULL,
`house_decorate_type` varchar(255) DEFAULT NULL,
`house_agent` varchar(255) DEFAULT NULL,
`house_agency` varchar(255) DEFAULT NULL,
`house_url` varchar(255) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
三、程序实现
3.1 使用scrapy创建项目
打开cmd，切换到PyCharm工程目录，执行：
scrapy startproject Anjuke
3.2 使用pycharm打开项目并安装好所需的第三方库
直接在pycharm中安装scrapy、pymysql和matplotlib（其他依赖库会自动安装）；另外注意，安装scrapy安成后复制一份cmdline.py到项目主目录下
3.3 创建程序所需文件
anjuke_sz_spider.py----楼盘信息爬取脚本
anjuke_sz_sh_spider.py----二手房信息爬取脚本
anjuke_sz_report.py----楼盘信息报告图表生成脚本
anjuke_sz_sh_report.py----二手房信息报告图表生成脚本
项目目录结构如下：
3.4 配置好scrapy调试运行环境
为anjuke_sz_sider.py和anjuke_sz_sh_spider.py配置好运行参数
3.5 各文件实现
