我正在尝试使用来自网页的适当参数来填充 json 响应，并发出 post http 请求。当我运行脚本时，我看到脚本卡住了并且没有带来任何结果。它也不会抛出任何错误。这是站点链接。在点击按钮之前，我从该站点的此表单的三个下拉列表中选择了三个选项Get times & tickets。
我试过：
import requests
from bs4 import BeautifulSoup
url = 'https://www.thetrainline.com/'
link = 'https://www.thetrainline.com/api/journey-search/'
payload = {"passengers":[{"dateOfBirth":"1991-01-31"}],"isEurope":False,"cards":[],"transitDefinitions":[{"direction":"outward","origin":"1f06fc66ccd7ea92ae4b0a550e4ddfd1","destination":"7c25e933fd14386745a7f49423969308","journeyDate":{"type":"departAfter","time":"2021-02-11T22:45:00"}}],"type":"single","maximumJourneys":4,"includeRealtime":True,"applyFareDiscounts":True}
with requests.Session() as s:
s.headers['User-Agent'] = 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.104 Safari/537.36'
s.headers['content-type'] = 'application/json'
s.headers['accept'] = 'application/json'
r = s.post(link,json=payload)
print(r.status_code)
print(r.json())
我怎样才能得到 json 响应，发出带有来自该站点的参数的 post 请求？
您缺少所需的标头：x-version和referer. 该referer标题指的是搜索表单，您可以建立它。在journey-search您必须发布availability请求之前。
