解析json文件，json接口，将内容入数据库（Python脚本）
本文主要是介绍解析json文件，json接口，将内容入数据库（Python脚本），对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
刚接触用Python解析数据，发现十分的方便
先来了解一下json.loads()、json.dumps()和json.dump()、json.load()四个函数
json.loads()、json.dumps()和json.dump()、json.load()分别是两组不一样用法
带s的用于数据类型的转换，不带s的用于操做文件。
json.loads()、json.dumps()概念理解
json自己是字符串，经过json.loads()、json.dumps()能够进行字典和字符串的转换。
由于浏览器不支持字典方式显示，若是请求过来的类型是字典，必须经过json.dumps()函数将字典转换为字符串以后，才可展现。
json.dump()和json.load()概念理解
主要用来读写json文件函数
1.通过接口解析json数据提取各个城市的实时疫情数据，没有在脚本里进行定时，不知道该怎么写定时任务（查百度也弄不明白），就在linux系统设置了，一天执行一次脚本
# -*- coding: utf-8 -*-
import requests
from bs4 import BeautifulSoup
import json
import time
from pymysql import *
def mes():
url = 'https://ncov.dxy.cn/ncovh5/view/pneumonia?from=timeline&isappinstalled=0' #请求地址
headers = {'user-agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.87 Safari/537.36 SLBrowser/6.0.1.6181'}#创建头部信息
resp = requests.get(url,headers = headers) #发送网络请求
content=resp.content.decode('utf-8')
print("content"+content)
soup = BeautifulSoup(content, 'html.parser')
print(soup)
listA = soup.find_all(name='script',attrs={"id":"getAreaStat"})
account =str(listA)
mes = account.replace('[<script id="getAreaStat">try { window.getAreaStat = ', '')
mes=mes.replace('}catch(e){}</script>]','')
#mes=account[52:-21]
#json.loads 用于解码 JSON 数据。该函数返回 Python 字段的数据类型。
messages_json = json.loads(mes)
print("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa")
print(messages_json)
times=time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time()))
print(times)
provinceList=[]
cityList=[]
lenth=total()
total()
sheng = len(messages_json)
con=sheng+(lenth)#算出数据库已有的条数+今天省份的条数，才是城市的开始id
print(sheng)
print(len(messages_json))
print(con)
for item in messages_json:
lenth+=1
provinceName=item['provinceName']
nowCount = item['currentConfirmedCount']
confirmedCount=item['confirmedCount']
suspectedCount=item['suspectedCount']
curedCount=item['curedCount']
deadCount=item['deadCount']
cities=item['cities']
provinceList.append((lenth,times,provinceName,None,nowCount,confirmedCount,suspectedCount,curedCount,deadCount))
for i in cities:
con+=1
provinceName = item['provinceName']
cityName=i['cityName']
nowCount = i['currentConfirmedCount']
confirmedCount = i['confirmedCount']
suspectedCount = item['suspectedCount']
curedCount = i['curedCount']
deadCount = i['deadCount']
cityList.append((con,times,provinceName,cityName,nowCount,confirmedCount,suspectedCount,curedCount,deadCount))
insert(provinceList,cityList)
return NULL
def insert(provinceList, cityList):
provinceTuple=tuple(provinceList)
cityTuple=tuple(cityList)
cursor = db.cursor()
sql = "insert into China values (%s,%s,%s,%s,%s,%s,%s,%s,%s) "
try:
cursor.executemany(sql,provinceTuple)
print("插入成功")
db.commit()
except Exception as e:
print(e)
db.rollback()
try:
cursor.executemany(sql,cityTuple)
print("插入成功")
db.commit()
except Exception as e:
print(e)
db.rollback()
cursor.close()
def total():
sql= "select * from China"
cursor = db.cursor()
try:
cursor.execute(sql)
results = cursor.fetchall()
lenth = len(results)
db.commit()
return lenth
except:
print('执行失败，进入回调1')
db.rollback()
# 连接数据库的方法
def connectDB():
try:
db = connect(host='localhost', port=3306, user='root', password='123456', db='db2',charset='utf8')
print("数据库连接成功")
return db
except Exception as e:
print(e)
return NULL
if __name__ == '__main__':
db=connectDB()
mes()
sql:
CREATE TABLE `china` ( `id` int(11) NOT NULL, `time` datetime NULL DEFAULT NULL, `provinceName` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '省，直辖市', `cityName` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '市', `nowCount` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '现存确诊', `confirmedCount` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '总共确诊', `suspectedCount` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '疑似', `curedCount` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '治愈', `deadCount` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '死亡', PRIMARY KEY (`id`) USING BTREE ) ENGINE = InnoDB CHARACTER SET = utf8mb4 COLLATE = utf8mb4_bin ROW_FORMAT = Dynamic; SET FOREIGN_KEY_CHECKS = 1;
2.是一个本地的json文件，解析，然后数据入库。和上面其实差不多
# coding:utf8

def mes():
with open(r"D:\alldata.json", 'r', encoding='UTF-8') as load_f:

print(load_dict)
load_dict = load_dict['stations'] # 拆第一层花括号
print(len(load_dict))
con = len(load_dict)
print(load_dict[0]['id'])
# data_raw = pd.DataFrame(columns=load_dict.keys())
# data_raw = data_raw.append(load_dict, ignore_index=True)
provinceList = []
lenth = select()
print("aaaaaaaaa")
print(select())
for item in load_dict:
print(lenth)
lenth = lenth + 1
print("bbbbbbbbbbbbbbbbbbbbbb")
print(lenth)
id = item['id']

print("相数")
print(provinceList)
insert(provinceList)
return NULL
def insert(provinceList):
provinceTuple = tuple(provinceList)
cursor = db.cursor()
sql = "insert into park_db values (%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s) "
