半个小时教你写一个毕设之地图搜租房
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
毕业生租房
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, 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)

@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:
