我试图了解当用户输入zipcode并从以下网站发出“POST”命令(通过单击“Shop Now”按钮)时,标题是如何构造的:
我相信这个“POST”请求中有趣的部分是站点如何形成以下标题,但我不知道它是如何做到的(我怀疑是有一些JavaScript/Angular代码造成的):
x-ccwfdfx7-a
x-ccwfdfx7-b
x-ccwfdfx7-c
x-ccwfdfx7-d
x-ccwfdfx7-f
x-ccwfdfx7-z
因此,我尝试使用requests
模块以来宾身份登录,以了解有关此流如何工作的更多信息:
到目前为止,我所有的尝试都失败了。这是我的密码:
import requests
from requests_toolbelt.utils import dump #pip install requests_toolbelt
import cloudscraper #pip install cloudscraper
#with requests.Session() as session:
with cloudscraper.create_scraper(
browser={
'custom': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.163 Safari/537.36'
}
) as session:
CITY = XXXXX
ZIPCODE = XXXXX
#get cookies
url = 'http://www.peapod.com'
res1 = session.get(url)
session.headers['Referer'] = 'https://www.peapod.com/'
#get more cookies
url = 'http://www.peapod.com/login'
res2 = session.get(url)
#get more cookies
url = 'https://www.peapod.com/ppd/bundles/js/ppdBundle.js'
res3 = session.get(url)
#get all the service locations
response = session.get('https://www.peapod.com/api/v4.0/serviceLocations',
params={
'customerType': 'C',
'zip': ZIPCODE
}
)
try:
loc_id = list(
filter(
lambda x: x.get('location', {}).get('city') == CITY, response.json()['response']['locations']
)
)[0]['location']['id']
except IndexError:
raise ValueError("Can't find City '{}' -> Zip {}".format(CITY, ZIPCODE))
#login as guest
response = session.post('https://www.peapod.com/api/v4.0/user/guest',
json={
'customerType': 'C',
'cities': None,
'email': None,
'serviceLocationId': loc_id,
'zip': ZIPCODE
},
params={
'serviceLocationId': loc_id,
'zip': ZIPCODE
}
)
这似乎产生了某种错误消息,说“我被阻止了”,我认为这是因为我无法理解浏览器如何在“POST”请求中构造ccwfdfx7
头(我怀疑有一些JavaScript/Angular代码负责构建这些头文件,但我找不到它,希望有人能帮忙……)
在同一台计算机上,Chrome浏览器可以很好地登录
