类库安装路径：python36/lib/site-package/requests

header需要加的

1. url-encode   2. json  3. xml  4.html


5、file 不要加

#3 form
# host = ‘http://ws.webxml.com.cn‘
# headers = {"Content-Type": "application/x-www-form-urlencoded"}
# r = requests.post(url=host + ‘/WebServices/WeatherWS.asmx/getSupportCityString‘,
#                   headers=headers, data={"theRegionCode": 311101})
# print(r.text)

#4 xml  java .net
# host = ‘http://ws.webxml.com.cn‘
# headers = {"Content-Type": "text/xml; charset=utf-8", "SOAPAction": "http://WebXml.com.cn/getSupportCityString"}
# xml = ‘‘‘<?xml version="1.0" encoding="utf-8"?>
# <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
#   <soap:Body>
#     <getSupportCityString xmlns="http://WebXml.com.cn/">
#       <theRegionCode>311101</theRegionCode>
#     </getSupportCityString>
#   </soap:Body>
# </soap:Envelope>‘‘‘
#
# r = requests.post(url=host + ‘/WebServices/WeatherWS.asmx‘,
#                   headers=headers, data=xml)
# print(r.text)

#5 json    data=json字符串    如果不用引号需要先转成字符串， json=字典
headers = {"Content-Type": "application/json; charset=utf-8"}
r = requests.post(url=‘http://139.199.132.220:8000/event/weather/getWeather/‘, headers=headers,
              data=‘{"theCityCode": 1}‘)

r2 = requests.post(url=‘http://139.199.132.220:8000/event/weather/getWeather/‘, headers=headers,
              json={"theCityCode": 1})

print(r.text)
print(r2.text)

requets库下载实现

import requests
header ={‘Cookie‘: ‘uid=1; token=44c972f05d76fdd93c31f9c2b65bb098f308cdfc‘}
url =‘http://118.24.91.97:9000/api/export/?month=1&city=110000‘
res = requests.get(url=url,headers=header)
#res.raw

with open(‘./result.csv‘, ‘wb‘) as fd:
    for text in res.iter_content(1024):
        fd.write(text)
