【问题描述】：
我的要求：
# python 3.7.3
import requests
from requests import Session
session = Session()
session.head('https://www.basspro.com/shop/en/blazer-brass-handgun-ammo')
cookies = requests.utils.cookiejar_from_dict(requests.utils.dict_from_cookiejar(session.cookies))
response = session.post(
url='https://www.basspro.com/shop/BPSGetInventoryStatusByIDView',
data={
'productId': '3074457345616736172',
'itemId': '3074457345616736949',
'isGunFlag': 'false',
},
cookies=cookies,
headers={
'accept': '*/*',
'accept-encoding': 'gzip, deflate, br',
'accept-language': 'en-US,en;q=0.9',
'content-length': '72',
'content-type': 'application/x-www-form-urlencoded',
'origin': 'https://www.basspro.com',
'referer': 'https://www.basspro.com/shop/en/blazer-brass-handgun-ammo',
'sec-fetch-mode': 'cors',
'sec-fetch-site': 'same-origin',
'user-agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.92 Safari/537.36 Vivaldi/2.9.1705.38',
'x-requested-with': 'XMLHttpRequest',
},
)
print(response.text)
输出：
<input type="hidden" class="relativeToAbsolute" value="true" />
/*
{
"onlineInventory": {
"status": "Status Not Available",
"image": "widget_product_info/outofstock_icon.svg",
"altText": "Status Not Available",
"isDropShip": false,
"availableDate":""
},
"inStoreInventory": {
"stores": [],
"checkStoreText": "Check Store Availability",
"isInStoreInventory": true,
"isPickupInventory": false
}
}
*/
通过浏览器检查和运行相同的 AJAX 请求时的输出：
/*
{
"onlineInventory": {
"status": "Backordered",
"image": "widget_product_info/backordered_icon.svg",
"altText": "Backordered",
"isDropShip": false,
"quantity": 0,
"availableDate":"May 1-8"
},
"inStoreInventory": {
"stores": [{
id: '715839555',
name: '83',
gunRestricted: 'false',
dsName: 'TX - Round Rock',
status: 'Unavailable',
statusText: 'Out of Stock',
image: 'widget_product_info/outofstock_icon.svg',
altText: 'Out of Stock',
availableDate: '',
availableQuantity: '',
availableQuantityDisplay: 'false',
cityState: 'Round Rock, TX',
ISPavailableDate: '',
ISPavailableQuantity: '',
pickupTime: 'by 2:00pm',
offerISPOnBPS: 'Yes',
offerISPOnCAB: 'No'}],
"checkStoreText": "Change Store",
"isInStoreInventory": true,
"isPickupInventory": true
}
}
*/
我也尝试过这样分配 cookie：
url = "https://www.basspro.com/shop/en/blazer-brass-handgun-ammo"
r = requests.get(url)
cookies = r.cookies
# fails to pass the right cookie
如果我改为从https://www.basspro.com/shop/en/blazer-brass-handgun-ammo 处检查的 GET 请求中逐字复制 cookie 并将其放入 POST 标头中，它可以工作。如何让 cookie 以编程方式正常工作？
编辑：
这是我尝试将 Session() 用于 cookie：
# python 3.7.3
import requests
from requests import Session
session = Session()
session.get("https://www.basspro.com/shop/en/blazer-brass-handgun-ammo")
# session.head('https://www.basspro.com/shop/en/blazer-brass-handgun-ammo')
response = session.post(
url='https://www.basspro.com/shop/BPSGetInventoryStatusByIDView',
data={
'productId': '3074457345616736172',
'itemId': '3074457345616736949',
'isGunFlag': 'false',
},
headers={
'accept': '*/*',
'accept-encoding': 'gzip, deflate, br',
'accept-language': 'en-US,en;q=0.9',
'content-length': '72',
'content-type': 'application/x-www-form-urlencoded',
'origin': 'https://www.basspro.com',
'referer': 'https://www.basspro.com/shop/en/blazer-brass-handgun-ammo',
'sec-fetch-mode': 'cors',
'sec-fetch-site': 'same-origin',
'user-agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.92 Safari/537.36 Vivaldi/2.9.1705.38',
'x-requested-with': 'XMLHttpRequest',
},
)
print(response.text)
我得到和以前一样的结果（“status”：“Status Not Available”等）
这是我对第二种解决方案的尝试：
# python 3.7.3
import requests
from requests import Session
url = "https://www.basspro.com/shop/en/blazer-brass-handgun-ammo"
r = requests.get(url)
cookies = r.cookies # the type is RequestsCookieJar
response = requests.post(
url='https://www.basspro.com/shop/BPSGetInventoryStatusByIDView',
data={
'productId': '3074457345616736172',
'itemId': '3074457345616736949',
'isGunFlag': 'false',
},
cookies=cookies,
headers={
'accept': '*/*',
'accept-encoding': 'gzip, deflate, br',
'accept-language': 'en-US,en;q=0.9',
'content-length': '72',
'content-type': 'application/x-www-form-urlencoded',
'origin': 'https://www.basspro.com',
'referer': 'https://www.basspro.com/shop/en/blazer-brass-handgun-ammo',
'sec-fetch-mode': 'cors',
'sec-fetch-site': 'same-origin',
'user-agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.92 Safari/537.36 Vivaldi/2.9.1705.38',
'x-requested-with': 'XMLHttpRequest',
},
)
print(response.text)
再次，我得到与以前相同的结果。我做错了什么？

是的。它们本质上没有善恶之分……这就是你如何使用它们。
