print(response.url)
with open("baidu.html","w",encoding="utf-8") as fp:
    fp.write(response.content.decode('utf-8'))

  }

data = {
    'first':'true',
    'pn':1,
    'kd':'python'
}
url = "https://www.lagou.com/jobs/positionAjax.json?needAddtionalResult=false"

response = requests.post(url=url,data=data,headers= headers)

print(type(response.json()))


三、request使用代理proxy




#   常用免费代理  1、西刺免费代理IP:http://www.xicidaili.com  2、快代理：http://www.kuaidaili.com  3、代理云:http://www.dailiyun.com
import requests
#使用代理
proxy = {
    'http':"136.228.128.14:61158"
}

url = "http://httpbin.org/ip"
response = requests.get(url=url,proxies=proxy)
print(response.text)




四、request建立会话session




import requests

# response = requests.get("http://www.baidu.com")
#
# print(response.cookies.get_dict())

#request建立会话
session = requests.session()


login_url = "http://172.18.254.102:8080/IBSManage/loginAction_login.action"

headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36",
    "Referer": "http://172.18.254.102:8080/IBSManage/login.jsp"
    }

data = {
    "curuser.username": "yaoy",
    "curuser.password": "sand"
}

session.post(url=login_url,headers=headers,data=data)


dapeng_url = "http://172.18.254.102:8080/IBSManage/trans_list.action"

trans_data = {
    "startDate":"2019-11-27",
    "endDate": "2019-11-27",
    "page": 1,
    "rows": 15
}
response = session.post(url=dapeng_url,data=trans_data,headers=headers)
print(response.json())
