house-renting-spider (English version)

A web spider for crawling accommodation rental information in Douban Group, which is a well-known Chinese online community.

System Requirements:

To start

# Clone the repo
$ git clone https://github.com/PeggyZWY/house-renting-spider
$ cd house-renting-spider

# Install requirements
$ pip install -r requirements.txt  

# Modify config.ini
$ vim config.ini

Configure in config.ini

  1. key_search_word_list is the wanted keywords for the rented accommodation. If there is more than one keyword, use , to delimit them.
  2. custom_black_list is the unwanted keyword. Similarly, if there is more than one keyword, use , to delimit them.
  3. start_time is the earliest date for the post posted. Set the date in the format like 2018-12-31.
  4. Under the option of [douban], douban_cookie and douban_sleep_time don't need to be changed, since the programme will set the cookie automatically. It is recommended to set douban_sleep_time to 1 second, in order not to be defined as a web spider by Douban.com.

For example:
config

After finishing configuration, type the following in the terminal:

$ python houseRentingSpider.py  

Then wait for the spider to work...

When it finishes, information like the following will be shown:
config

According to the address, open the HTML in any brower and the example results are shown as followes:
config

Others

In houseRentingSpider.py, there are groups set as following for example.

config

The group number in the URL list in douban_url should be correspondent to the names in douban_url_name.

In all, after setting the groups here, and setting keywords in config.ini, you can have your own web spider.

System Requirements:

To start

# Clone the repo
$ git clone https://github.com/PeggyZWY/house-renting-spider
$ cd house-renting-spider

# Install requirements
$ pip install -r requirements.txt  

# Modify config.ini
$ vim config.ini

config.ini里配置并保存:

  1. key_search_word_list为想要搜索的关键词。如果有多个关键词,请用英文逗号,隔开
  2. custom_black_list为拒绝的关键词黑名单。同样如果有多个关键词,请用英文逗号,隔开
  3. start_time为要搜索在这个时间之后的信息。请用2018-12-31这种格式表示日期
  4. [douban]这个option下的douban_cookiedouban_sleep_time不需要改变。程序里会自动设置cookie;douban_sleep_time设为1秒钟比较合适,防止豆瓣反爬虫封号

比如:
config

配置好之后继续在终端输入:

$ python houseRentingSpider.py  

然后就等爬虫爬呀爬。

结束之后,命令行有提示。比如:
config

根据提示打开此HTML文件后会出现结果。比如(截图仅截取部分结果):
config

配色是根据豆瓣来的嘿嘿:)

Others

houseRentingSpider.py里,现在设置了如下小组。

config

douban_url这个数组里URL的参数中group的值以及douban_url_name数组里的小组名要一一对应。

也就是说,只要你是在豆瓣小组里对关键字进行爬取,在这里设置小组,在config.ini设置关键词,就可以定制出自己的爬虫。
