#加载模块

import json

#请求地址

#发送请求
response=requests.get(url=url,headers=headers)
 
 
#数据解析
data_html=response.text
#【0】转换数据类型从list到str,强大的正则
json_str=re.findall('"component":\[(.*)\],',data_html)[0]
#转换字典
json_dict=json.loads(json_str)
caseList=json_dict['caseList']
 
for case in caseList:
    area=case['area']#
    confirmed=case['confirmed']#
    curConfirm=case['curConfirm']
    asymptomatic=case['asymptomatic']
    crued=case['crued']#
    died=case['died']#
    confirmedRelative=case['confirmedRelative']
    diedRelative=case['diedRelative']
    curedRelative=case['curedRelative']
    asymptomaticRelative=case['asymptomaticRelative']
    nativeRelative=case['nativeRelative']
    overseasInputRelative=case['overseasInputRelative']
 #打印检查  print(area,confirmed,curConfirm,confirmedRelative,nativeRelative,overseasInputRelative, asymptomatic,asymptomaticRelative,crued,curedRelative,died,diedRelative)
#写入表格    
with open('./data.csv',mode='a',encoding='utf-8',newline='')as f:
        csv_writer=csv.writer(f)
        csv_writer.writerow([area,confirmed,curConfirm,confirmedRelative,nativeRelative,overseasInputRelative,asymptomatic,asymptomaticRelative,crued,curedRelative,died,diedRelative])
