首先需要一个Python3环境,怎么准备我就不多说了,实在不会的出门右转看一下廖雪峰老师的博客.

HTML部分

• 代码来自:高德API+Python解决租房问题,简单改了下加载数据部分

代码路径:/static/index.html

    
    
    
    
    
    
    
    
    
    
    
    

    

        

            选择工作地点：
            

                
            
        
        

            选择通勤方式：
            

                 公交+地铁                 地铁            
        
    
    

    

Python flask部分

Python3环境,使用安装Flask,pymysql,BeautifulSoup

pip install Flask;pip install pymysql;pip install beautifulsoup4;pip install requests;

然后直接上代码咯.

路径:/app.py

from flask import Flask, requestfrom flask import jsonifyfrom flask import render_templatefrom flask import Responseimport requestsfrom bs4 import BeautifulSoupimport pymysql
app = Flask(__name__)@app.route("/get_houses_db/")def get_houses_db():
    # 从数据库读出来的数据,url为房源url,address为房源定位地址
    houses = []    # Connect to the database
    connection = pymysql.connect(host='127.0.0.1',
                                 user='root',
                                 password='123',
                                 db='你的数据库名字',
                                 charset='utf8mb4',
                                 cursorclass=pymysql.cursors.DictCursor)    try:        with connection.cursor() as cursor:            # Read a single record
            sql = "SELECT 你的URL字段,你的地址字段 FROM 你的房源数据表 where 1=1;"
            keyword = request.args.get('keyword')            if keyword is not None:
                sql = sql + "查询字段 like %%s%" % keyword
            cursor.execute(sql)
            houses = cursor.fetchall()    finally:
        connection.close()    return jsonify(houses)@app.route("/get_houses", methods=['POST', 'GET'])def get_houses():
    # 直接从网页获取数据,url为房源url,address为房源定位地址
    houses = []
    city = request.args.get('city')    if city is None:
        city = 'bj'
    city_url = 'http://%s.58.com' % city    for page_num in range(1, 10):

        }
        response = requests.request("GET", url, headers=headers)
        htmlSoup = BeautifulSoup(response.text, "html.parser")
        ul = htmlSoup.find(attrs={"class": "list"})        if ul is None:            continue
        li_list = ul.find_all("li")        if li_list is None:            continue

            house['url'] = '%s/%s' % (city_url, li.find("a")['href'])
            house['address'] = li.find("h2").text
            houses.append(house)    return jsonify(houses)@app.route('/')def index():
    return app.send_static_file('index.html')if __name__ == '__main__':
    app.run(port=8888)# python3 安装flask之后,安装命令pip install Flask# 运行 python app.py

效果图:

然后...

写完了...
