Python中如何实现MOOC扫码登录

session = requests.session()
url = 'https://www.icourse163.org/logonByQRCode/code.do?width=182&height=182'   # 扫码登录url
header = {
    'referer': 'https://www.icourse163.org/',
    'user-agent': ua
}
resp = session.get(url,headers = header).json()		# 拿到相应的json数据
codeUrl = resp['result']['codeUrl']				# 提取二维码url及唯一标志key
pollKey = resp['result']['pollKey']
codejpg = session.get(codeUrl)				# 请求二维码
with open('text.jpg','wb') as f:			# 下载二维码
    f.write(codejpg.content)

checkUrl = f'https://www.icourse163.org/logonByQRCode/poll.do?pollKey={pollKey}'
os.system('start text.jpg')
token = None
for i in range(20):				# 模拟轮询
    checkResp = session.get(checkUrl,headers = header).json()
    if checkResp['result']['codeStatus'] == 2:
        token = checkResp['result']['token']		# 提取token
    else:
        time.sleep(1)			# 每秒一次

os.system('start text.jpg')

vaildateUrl = f'https://www.icourse163.org/passport/logingate/mocMobChangeCookie.htm?token={token}&returnUrl=aHR0cHM6Ly93d3cuaWNvdXJzZTE2My5vcmcvaW5kZXguaHRt'	# returnUrl指MOOC网
session.get(vaildateUrl,headers = header)
