python 安居客 爬虫_Python爬虫安居客房价信息（并利用百度地图API查询坐标）

好的，以下是爬取安居客房价信息并利用百度地图API查询坐标的Python爬虫代码：

import requests
from bs4 import BeautifulSoup
import json

def get_location(city, address):
    url = 'http://api.map.baidu.com/geocoder/v2/'
    params = {
        'address': address,
        'city': city,
        'output': 'json',
        'ak': '你的百度地图API密钥'
    }
    res = requests.get(url, params=params)
    json_data = json.loads(res.text)
    if json_data['status'] == 0:
        location = json_data['result']['location']
        return location['lng'], location['lat']

def get_house_price(city, area):
    url = 'https://{0}.anjuke.com/market/{1}/'.format(city, area)
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
    res = requests.get(url=url, headers=headers)
    soup = BeautifulSoup(res.text, 'lxml')
    house_price_list = []
    for tr in soup.select('.sale-estate-table tr')[1:]:
        tds = tr.select('td')
        house_name = tds[0].text.strip()
        house_address = tds[1].text.strip()
        house_price = tds[2].text.strip()
        house_location = get_location(city, house_address)
        if house_location:
            house_price_list.append({
                'name': house_name,
                'address': house_address,
                'price': house_price,
                'location': house_location
            })
    return house_price_list

if __name__ == '__main__':
    city = 'sh'
    area = 'pudongxinqu'
    house_price_list = get_house_price(city, area)
    print(house_price_list)

其中，`get_location`函数用于利用百度地图API查询地址的坐标，`get_house_price`函数用于爬取安居客网站上的房价信息。在`if __name__ == '__main__'`中，我们可以指定城市和区域，通过调用`get_house_price`函数来获取该区域内的房价信息，并将结果打印出来。

注意：在使用本代码前请替换百度地图API密钥。
