首先需要一個Python3環境,怎么準備我就不多說了,實在不會的出門右轉看一下廖雪峰老師的博客.

代碼來自:高德API+Python解決租房問題,簡單改了下加載數據部分

代碼路徑:/static/index.html

    
    
    
    
    
    
    
    
    
    
    



    

    

        

            選擇工作地點：
            

                
            
        
        

            選擇通勤方式：
            

                 公交+地鐵
                 地鐵
            
        
    
    

    

Python3環境,使用安裝Flask,pymysql,BeautifulSoup

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

然后直接上代碼咯.

路徑:/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():
    # 從數據庫讀出來的數據,url為房源url,address為房源定位地址
    houses = []
    # Connect to the database
    connection = pymysql.connect(host="127.0.0.1",
                                 user="root",
                                 password="123",
                                 db="你的數據庫名字",
                                 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 你的房源數據表 where 1=1;"
            keyword = request.args.get("keyword")
            if keyword is not None:
                sql = sql + "查詢字段 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():
    # 直接從網頁獲取數據,url為房源url,address為房源定位地址
    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",

        }
        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 安裝flask之后,安裝命令pip install Flask
# 運行 python app.py

然后...

寫完了...
