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.

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
            
        
    
    

    

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, request
from flask import jsonify
from flask import render_template
from flask import Response
import requests
from bs4 import BeautifulSoup
import 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):
        url = "%s/pinpaigongyu/pn/%d/" % (city_url, page_num)
        headers = {
            "connection": "keep-alive",
            "upgrade-insecure-requests": "1",

            "cache-control": "no-cache",
        }
        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
        for li in li_list:
            house = {}
            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...

下次见...
