1安装mongoDB，配置成功
2在pycharm上配置连接成功，也能够查看到数据库，及数据库中存储内容的大小，
！！！！！
但是无法可视化查看数据库存储的具体内容。
import requests
import json
from bs4 import BeautifulSoup
import re
import csv
import time
import pymongo
# 建立连接
client = pymongo.MongoClient('localhost',27017)
# 在mongo中新建名为weather的数据库
book_weather = client['weather']
# 在weather库中新建名为sheet_weather_3的表
sheet_weather = book_weather['sheet_weather_3']
csv_file = csv.reader(open('china-city-list.csv','r',encoding='UTF-8'))
print(csv_file)
data1=list(csv_file)
# date1 = data1.split("\r")
for i in range(3):
data1.remove(data1[0])
for item in data1[:10]:
print(item[0:11])
url = 'https://free-api.heweather.net/s6/weather/now?location=' + item[0] + '&key=756d9a91c4f74734847eab104367c984'
print(url)
strhtml = requests.get(url)
strhtml.encoding='utf8'
time.sleep(1)
dic = strhtml.json()
# print(strhtml.text)
sheet_weather.insert_one(dic)
