requests( proxy | post | session ) 使用練習

import requests

import os

url = 'http://pic.gooooal.com/images/100452/100452654.jpg'

# proxies = {'http':'220.184.213.250:808'}

# 私密代理
ip = os.environ.get('proxyServer')

user = os.environ.get('proxyuser')

password = os.environ.get('password')

print(ip,user,password)
private_proxies = {'http':'http://%s:%s@%s'%(user,password,ip)}


response = requests.get(url = url,proxies = private_proxies,timeout = 5)

with open('./download/C羅3.jpg',mode='wb') as fp:
    # response中content二進制的內容
    fp.write(response.content)

import requests

print(response.text)

import requests

# Session 可以保留Cookie
# 相當於urllib中Cookiejar

session = requests.Session()


# 第一次發起Post請求，爲了登陸，保存登陸的信息，Cookie
url = 'http://zs.1000phone.net/Admin/login'

form = {'AdminName':'[email protected]',
        'PassWord':'19871211hhll$'}

response = session.post(url=url,data=form)
print(response.text)

# 第二次，使用session，進行網絡訪問的時候，session，記錄Cookie
# url = 'http://zs.1000phone.net/Collect/index/zone_id/0/course_id/50'
# response = session.get(url=url)
#
# print(response.text)
